NOVEL CARDANOL-BASED ORGANIC VULCANIZING AGENT, PRODUCTION METHOD FOR SAME AND BLENDED RUBBER COMPOSITION FOR TYRES USING SAME

摘要

Disclosed are a method for preparing a cardanol-based organic vulcanizing agent, including a step of reacting cashew nut extract with powdered sulfur, a cardanol-based organic vulcanizing agent obtained by the method, and a rubber compound and tire composition using the same. The rubber composition using the cardanol-based organic vulcanizing agent shows significantly improved expected mileage (FPS), tensile strength (T/S), non-vulcanized properties and wet traction as compared to the rubber composition using the conventional vulcanizing agent, and contributes to improvement of wear property of tires as final products in actual cars. Therefore, the cardanol-based organic vulcanizing agent can be applied advantageously to rubber compound compositions for tires used in rubber vulcanizing processes for tire treads.
