Novel cardanol-based organic vulcanizing agent, method for producing the same, and rubber compounding composition for tires using the same

摘要

The present invention relates to a method for producing a cardanol-based organic vulcanizing agent comprising a step of reacting cashew nut shell extract and powdered sulfur, a cardanol-based organic vulcanizing agent produced by the method, and a rubber compound using the same, A tire composition is also provided. The rubber composition using the cardanol-based organic vulcanizing agent according to the present invention has an expected running mileage (FPS), a tensile strength (T / S, Tensile strength), an unvulcanized characteristic, and a contact property to a wet road surface. Is significantly improved compared to when using a conventional vulcanizing agent, and contributes to the improvement of the actual vehicle wear performance of the tire, which is the final product using this, the rubber compound used in the rubber vulcanization process for tire treads It can be effectively applied to the composition.
