Bio-Based Materials for Tire Production

A pneumatic tire containing a majority of sustainable content. The tire has over 85% of its components made from sustainable materials like bio-based carbon black, recycled steel, renewable rubber, and biodegradable additives. This provides a tire with significantly higher renewable content compared to conventional tires. The sustainable tire maintains or exceeds performance of traditional tires. The replacement of non-renewable materials with sustainable ones reduces environmental impact while meeting or improving tire performance.

Eco-friendly tire tread rubber composition with improved dispersibility that replaces some of the silica with a hydrophobic rice bran silica prepared by mixing rice bran silica with a liquid unsaturated fatty acid. This improves dispersion of the filler in the rubber matrix compared to using rice bran silica alone. The hydrophobic rice bran silica provides environmental benefits from rice bran waste while maintaining dispersion and processing properties.

Bio-based low-temperature resistant elastomer for tires that can be used in winter conditions without crystallization at low temperatures. The elastomer is made by coordination chain transfer polymerization of bio-based monomers like myrcene and isoprene. The copolymer has a high cis-1,4 structure (90-96%) and low glass transition temperature (-70 to -60°C) due to the mushroom-shaped side groups from the myrcene monomer. This prevents crystallization at low temperatures for better low-temp performance compared to traditional rubber. The bio-based elastomer can be used in winter tire compounds to reduce fossil resource use in tires.

All-steel/semi-steel radial tire sidewall rubber composition that uses bio-based, renewable oil instead of petroleum-based oil to reduce reliance on fossil resources and lower environmental pollution. The composition contains natural rubber, butadiene rubber, carbon black, bio-based oil, stearic acid, zinc oxide, microcrystalline wax, antioxidants, oil-extended sulfur, and accelerator. The bio-based oil is extracted and synthesized from plants and has lower polycyclic aromatic hydrocarbons (PAHs) compared to petroleum oil. This reduces proton levels in the tire sidewalls and meets sustainable development requirements.

Rubber composition for tires containing an oligomeric product made from pyrolysis oil as a replacement for conventional petroleum-based resins. The oligomeric product is prepared by polymerizing the dienes and olefins in the pyrolysis oil using a Friedel-Crafts catalyst. It has a low molecular weight, low viscosity, and aromatic content. The oligomeric product provides rubber properties like glass transition temperature below -20°C and compatibility with elastomers like natural and synthetic rubbers. The pyrolysis oil-derived resin can replace petroleum resins in rubber compositions to recycle waste plastics and valorize the olefins and dienes in pyrolysis oil.

Tire tread composition containing modified natural oil as a processing aid. The modified natural oil is made by reacting epoxidized natural oil with an organic acid or anhydride. It can replace petroleum-based process oils in tire rubber compounds. The modified natural oil provides similar processing benefits without the issues of PAH contamination and vegetable oil compatibility. The modified natural oil content is 5-40 parts per 100 parts of rubber. The modified natural oil improves tire properties like dispersibility of silica, low temperature flexibility, and wear resistance compared to conventional process oils.

Functionalized bio-based elastomer for tires with low rolling resistance made by copolymerizing fumarate and conjugated diene monomers. The functionalization involves adding a third monomer that can react with white carbon black filler. The functionalized copolymer is prepared by emulsion polymerization in a nitrogen atmosphere. The resulting latex is demulsified and dried to obtain the functionalized fumarate/conjugated diene copolymer raw rubber. This bio-based elastomer can be used in tire tread compounds to provide low rolling resistance properties and enable "green tire" treads.

Bio-based compound modified liquid reclaimed rubber for tire applications that replaces traditional plasticizers, tackifying resins, and softeners. The modified rubber is prepared by high-temperature reaction of reclaimed rubber, lignin derivatives, and a peptizing agent. This bio-based rubber can be used to partially or fully replace conventional additives in tire rubber compositions to improve sustainability and reduce environmental impact compared to petroleum-based additives.

Tire tread rubber composition with high biobased content and reduced carbon footprint. The tread rubber is made by mixing specific amounts of raw rubber, reinforcing filler, activator, plasticizer, anti-aging agent, accelerator, and vulcanizing agent. The composition aims to replace fossil-based rubber with biobased rubber, like itaconate rubber, to reduce dependence on petroleum. The low-temperature vulcanization process and omitting silane coupling agent further reduce carbon emissions. The composition provides tires with high biobased content, good wet grip, and lower rolling resistance.

Rubber composition for tires made from biomass sources like coffee grounds that replaces petroleum-based components. The composition uses extracts and byproducts from lipid-rich biomass like coffee grounds to replace conventional processing oils, fillers, accelerators, and antioxidants. The extraction involves using solvents like alcohols and hydrocarbons to simultaneously extract oil, fatty acids, and phenols from biomass. The extract, called an all-in-one activator, is used in the tire composition along with biomass-derived carbon black. This allows using biomass as a source for tire components instead of petroleum-based ones.

Tire tread rubber composition with improved processability and environmental friendliness by replacing some of the silica with a phenolic polymer derived from lignin. The composition contains an additive made of lignin, a fat-soluble phenolic polymer, in the rubber base. This improves the processability of the rubber during manufacturing by reducing viscosity and improving mobility of the polymer chains. It also allows partial replacement of silica for environmental benefits. The lignin additive contains an imine group that undergoes reversible dynamic bond exchange at elevated temperatures, contributing to the processability improvements.

Rubber composition and tire for improved fuel economy, bleed resistance, and reduced CO2 emissions. The rubber composition contains a plant oil with specific properties. The plant oil is a glycerol fatty acid triester with a molecular weight above 800 g/mol. This oil functions as a plasticizer in the rubber. Using this high molecular weight plant oil provides better overall performance compared to conventional oils. The tire incorporating this composition has improved fuel efficiency, reduced bleed resistance, and lower CO2 emissions compared to conventional tires.
