Specification

Description:FIELD OF THE INVENTION:
The field of the invention relates to the development of specialized coating compositions for tyres, specifically aimed at preventing oxidative degradation. The invention addresses challenges in tyre durability and performance by incorporating anti-oxidative properties, enhancing resistance to environmental factors such as UV radiation, ozone, and temperature fluctuations.

BACKGROUD OF THE INVENTION:
Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Tyres are a critical component of vehicles, directly influencing safety, performance, and durability. Over time, tyres are exposed to harsh environmental conditions, including ultraviolet (UV) radiation, ozone, temperature fluctuations, and oxygen in the atmosphere. These factors contribute to oxidative degradation, which compromises the structural integrity and longevity of tyres. Oxidative degradation occurs when oxygen interacts with the rubber compounds in tyres, leading to hardening, cracking, and loss of elasticity. This process significantly reduces the performance of tyres and poses safety risks, including blowouts and reduced traction. The need for effective solutions to counteract this degradation has become a pressing concern for both manufacturers and consumers.
Historically, tyre manufacturers have employed various strategies to address oxidation issues. The use of antioxidants and stabilizers in rubber formulations is a common approach. These chemical additives are incorporated during the manufacturing process to delay the onset of oxidative reactions. However, these measures have limitations. Antioxidants can lose their effectiveness over time as they are consumed during the oxidation process, and their efficacy may diminish in extreme environmental conditions. Moreover, the internal dispersion of antioxidants may not provide adequate protection to the outer surface of the tyre, where oxidative exposure is most pronounced. As a result, tyres remain vulnerable to surface cracking and deterioration despite these efforts.
External protective coatings have been explored as an alternative to enhance the oxidative resistance of tyres. Coatings can act as a physical barrier, shielding the rubber from direct contact with oxygen, ozone, and UV rays. However, many existing coating solutions lack long-term durability, adhesion, or the ability to maintain their protective properties under continuous exposure to environmental stressors. Additionally, some coatings may affect the flexibility of the tyre surface, leading to performance issues such as reduced grip or increased rolling resistance. The development of a specialized anti-oxidation coating composition that overcomes these challenges is essential for improving tyre performance and extending their lifespan.
The invention of a robust anti-oxidation coating composition for tyres aims to address these longstanding issues by providing a solution that combines durability, adhesion, and flexibility. The formulation includes advanced polymers and chemical stabilizers that synergistically enhance the oxidative resistance of the tyre surface. The coating composition is designed to form a uniform, thin, and transparent layer that adheres strongly to the tyre surface without compromising its mechanical properties. This ensures that the protective barrier remains intact under varying environmental conditions, including high temperatures, humidity, and UV exposure.
One of the key innovations in the invention is the incorporation of nano-additives into the coating formulation. Nano-additives, such as titanium dioxide or zinc oxide nanoparticles, provide exceptional resistance to UV radiation and oxidative agents. These nanoparticles create a dense protective network that prevents oxygen and ozone molecules from penetrating the rubber surface. Additionally, the small size of the nanoparticles ensures that the coating remains smooth and does not alter the appearance or texture of the tyre. This feature makes the coating suitable for use in both consumer and commercial vehicles, addressing aesthetic and performance considerations.
The invention also emphasizes eco-friendliness and sustainability in its design. Traditional coatings often rely on volatile organic compounds (VOCs), which can have adverse environmental and health impacts. The proposed anti-oxidation coating composition uses low-VOC or VOC-free solvents, making it a safer and more environmentally friendly option. Furthermore, the coating application process is designed to be simple and scalable, enabling efficient deployment in tyre manufacturing facilities or as a post-market solution for tyre maintenance.
Another significant advantage of the invention is its ability to enhance the safety and reliability of tyres in critical applications. In commercial vehicles, such as trucks and buses, tyres are subjected to intense wear and tear due to heavy loads and extended usage. The anti-oxidation coating composition provides an additional layer of protection, reducing the likelihood of tyre failures and associated maintenance costs. Similarly, for passenger vehicles, the coating ensures consistent performance, even in regions with extreme climates. By preventing oxidative degradation, the coating helps maintain the elasticity and grip of the tyres, improving vehicle handling and reducing the risk of accidents.
The invention also aligns with the growing demand for sustainable transportation solutions. By extending the lifespan of tyres, the coating composition reduces the frequency of tyre replacements, thereby minimizing the environmental impact associated with tyre disposal. Used tyres contribute significantly to landfill waste, and their improper disposal can lead to environmental hazards such as soil and water pollution. The invention offers a proactive approach to reducing this waste by improving the durability and service life of tyres, contributing to a more sustainable automotive industry.
In addition to its primary function of preventing oxidative degradation, the coating composition can be tailored to incorporate secondary functionalities. For instance, the formulation can be modified to include hydrophobic agents, making the tyres resistant to water and dirt accumulation. This not only enhances the visual appeal of the tyres but also reduces maintenance requirements for vehicle owners. The multi-functional nature of the coating composition underscores its versatility and potential for widespread adoption in various automotive sectors.
The development of this anti-oxidation coating composition represents a significant advancement in tyre technology. By addressing the limitations of existing solutions, the invention provides a comprehensive approach to enhancing tyre durability, performance, and safety. The combination of advanced materials, innovative formulation techniques, and eco-friendly design ensures that the coating composition meets the demands of modern vehicles while contributing to environmental sustainability. This invention has the potential to set a new standard for tyre protection, offering long-lasting benefits to manufacturers, consumers, and the environment alike.

With reference to FIG. 1,
The present invention pertains to an advanced anti-oxidation coating composition specifically formulated for tyres to address the challenges of oxidative degradation. Oxidation, a process accelerated by exposure to oxygen, ozone, UV radiation, and environmental fluctuations, significantly compromises the durability, performance, and safety of tyres. The invention introduces a robust coating that forms a protective barrier, enhancing the longevity and reliability of tyres under diverse operating conditions.
The formulation consists of a carefully balanced combination of materials designed to provide optimal flexibility, durability, and resistance to oxidative and environmental stressors. The primary component of the composition is an elastomeric polymer base, constituting 40-50% of the formulation. This polymer base is selected from butadiene-based elastomers or synthetic rubbers, which are known for their superior elasticity and strong adhesion properties. The elastomeric base ensures that the coating conforms seamlessly to the tyre surface, maintaining flexibility and mechanical integrity even under dynamic conditions such as high-speed rotation and surface deformation.
To further enhance the protective qualities of the coating, the composition incorporates 5-10% nano-additives, such as titanium dioxide or zinc oxide nanoparticles. These nano-additives play a critical role in providing UV resistance and oxidative stability. Their nanoscale size allows for the formation of a dense, uniform barrier that prevents the penetration of oxygen, ozone, and UV radiation into the rubber surface. The use of nano-additives ensures that the coating provides long-lasting protection without altering the visual or physical properties of the tyre.
Anti-oxidants, in the range of 5-7%, are included in the formulation to neutralize free radicals generated during the oxidative degradation process. The anti-oxidants, such as hindered phenols or amines, act as scavengers for these reactive species, effectively halting the chain reaction that leads to material deterioration. This addition significantly extends the functional lifespan of the tyre, particularly under conditions of prolonged exposure to harsh environmental elements.
To improve the durability and adhesion of the coating, 3-5% crosslinking agents are incorporated into the composition. These agents facilitate chemical bonding between the coating and the tyre surface, ensuring that the protective layer remains intact even under mechanical stress or thermal fluctuations. The crosslinking process enhances the overall structural integrity of the coating, providing a durable shield against oxidative and physical damage.
The inclusion of UV stabilizers, also in the range of 3-5%, further fortifies the coating against photodegradation. These stabilizers, such as benzophenones or hindered amines, absorb harmful UV radiation, protecting the underlying rubber from damage. This feature is particularly beneficial for tyres used in regions with high solar intensity, where UV exposure can accelerate material degradation.
To ensure the coating retains its flexibility and does not crack under varying temperatures, the formulation includes 5-8% plasticizers. These additives improve the coating's adaptability, allowing it to expand and contract with the tyre material without losing its protective qualities. The plasticizers also contribute to the ease of application, ensuring a smooth and even layer during the coating process.
The composition utilizes 20-25% low-VOC or VOC-free solvents to ensure environmental sustainability and safety. These solvents aid in the uniform dispersion of the coating components, facilitating application via methods such as spraying, brushing, or rolling. The use of low-VOC or VOC-free solvents aligns with current environmental standards and reduces the health risks associated with traditional solvent-based coatings.
To further enhance the functionality of the coating, 2-4% optional hydrophobic agents, such as silane-based compounds, are included. These agents impart water and dirt repellency to the coating, reducing the accumulation of contaminants on the tyre surface. This feature not only enhances the visual appeal of the tyres but also minimizes maintenance requirements for vehicle owners.
The application of the coating composition follows a straightforward and scalable method. The tyre surface is first cleaned to remove any contaminants that might hinder adhesion. The composition is then applied using techniques such as spraying, brushing, or rolling, ensuring a uniform layer over the entire surface. Finally, the coating is allowed to cure at ambient or elevated temperatures, forming a transparent, durable, and flexible protective layer.
The coated tyres exhibit significantly enhanced oxidative resistance, durability, and performance under various environmental conditions. The coating preserves the elasticity and grip of the tyres, ensuring optimal safety and handling without compromising rolling resistance or mechanical properties. The multifunctional nature of the coating provides additional benefits, such as UV resistance, oxidative stability, and hydrophobicity, making it suitable for a wide range of applications.
The invention also addresses the growing need for sustainable solutions in the automotive industry. By extending the lifespan of tyres, the coating reduces the frequency of replacements, thereby minimizing tyre waste in landfills. This contributes to environmental conservation and supports a circular economy by reducing the ecological footprint of tyre manufacturing and disposal.
The versatility of the composition makes it suitable for use in passenger vehicles, commercial vehicles, and specialty tyres designed for extreme operating conditions. The coating provides consistent performance across diverse applications, ensuring reliability and safety in various settings.
Therefore, the present invention offers an innovative and sustainable solution to the challenges of tyre oxidation. The carefully balanced formulation, comprising elastomeric polymers, nano-additives, anti-oxidants, crosslinking agents, UV stabilizers, plasticizers, solvents, and optional hydrophobic agents, delivers superior protection and functionality. The straightforward application process and multifunctional properties of the coating make it a valuable advancement in tyre technology, benefiting manufacturers, consumers, and the environment alike.

Working of the invention: The invention works by forming a durable and flexible protective layer on the surface of tyres to shield them from oxidative degradation and environmental stressors. The mechanism involves the synergistic action of the carefully formulated components in the anti-oxidation coating composition, each playing a specific role to enhance the tyre's longevity and performance.
The elastomeric polymer base, which forms 40-50% of the composition, acts as the primary medium for the coating. When applied, it creates a flexible, adherent layer that conforms to the tyre's surface, maintaining its elasticity even under dynamic conditions such as rotation, deformation, and varying temperatures. The strong adhesion ensures that the coating remains intact, providing consistent protection over the tyre's lifetime.
Nano-additives, such as titanium dioxide or zinc oxide nanoparticles, comprising 5-10% of the formulation, are dispersed uniformly throughout the coating. These nanoparticles create a dense, impermeable barrier that blocks oxygen, ozone, and UV radiation from reaching the rubber surface. The nanoscale size of these additives ensures a smooth and even application, which enhances both the aesthetic and functional properties of the coating. This barrier prevents the initiation of oxidative reactions, thereby significantly reducing surface cracking and degradation.
Anti-oxidants, present at 5-7%, work at the chemical level to neutralize free radicals generated during the oxidative process. These compounds interrupt the chain reactions that lead to the breakdown of rubber polymers, effectively slowing down the ageing process of the tyre. By scavenging reactive oxygen species, the anti-oxidants help preserve the tyre's structural and mechanical properties.
The crosslinking agents, comprising 3-5% of the formulation, enhance the durability of the coating by forming chemical bonds with the tyre surface. These bonds create a robust interface between the tyre and the coating, ensuring that the protective layer remains securely attached even under mechanical stress or prolonged exposure to environmental factors. This ensures the longevity and reliability of the coating in real-world applications.
UV stabilizers, at 3-5%, absorb harmful ultraviolet radiation and dissipate it as harmless heat. This prevents photodegradation of the rubber material, a common issue in tyres exposed to high-intensity sunlight. The stabilizers ensure that the tyre retains its elasticity and mechanical strength, even in regions with high solar exposure.
The inclusion of 5-8% plasticizers enhances the flexibility of the coating, allowing it to adapt to the tyre's natural expansion and contraction caused by temperature changes. This prevents the coating from cracking or peeling, maintaining a seamless protective barrier throughout the tyre's operational life.
The low-VOC or VOC-free solvents, making up 20-25% of the composition, ensure uniform dispersion of all the components during application. These solvents evaporate during the curing process, leaving behind a uniform and smooth coating layer. The environmentally friendly nature of these solvents also ensures safe application processes and reduced ecological impact.
Optional hydrophobic agents, comprising 2-4%, work to repel water and dirt from the tyre surface. These agents create a self-cleaning effect, reducing the accumulation of contaminants and preserving the tyre's appearance and functionality. This feature is particularly beneficial in wet or muddy conditions, where tyres are more prone to dirt accumulation.
The application of the coating begins with thorough cleaning of the tyre surface to remove dirt, grease, and other contaminants. This ensures maximum adhesion of the coating to the rubber. The composition is then applied using methods such as spraying, brushing, or rolling, ensuring a uniform layer over the tyre. After application, the coating is allowed to cure at ambient or elevated temperatures. During curing, the solvents evaporate, and the crosslinking agents form durable chemical bonds, creating a transparent and flexible protective layer.
Once cured, the coated tyre exhibits enhanced resistance to oxidative and environmental damage. The coating prevents oxygen, ozone, and UV radiation from penetrating the tyre surface, thereby reducing cracking, hardening, and other signs of ageing. The tyre retains its elasticity, grip, and mechanical properties, ensuring consistent performance and safety.
The invention not only prolongs the service life of tyres but also reduces the frequency of tyre replacements, contributing to environmental sustainability. By minimizing the degradation caused by environmental factors, the coating helps reduce waste and the ecological footprint of tyre disposal. The ease of application and scalability of the process make the invention suitable for both tyre manufacturers and post-market maintenance solutions.
Overall, the working of the invention demonstrates a comprehensive approach to protecting tyres from oxidative damage, ensuring durability, safety, and sustainability in a wide range of automotive applications.
