Title:

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

Document Type and Number:

WIPO Patent Application WO/2015/005568

Kind Code:

A1

Abstract:

The present invention provides: a production method for a cardanol-based organic vulcanizing agent, the method comprising a step of reacting a cashew nut extract and powdered sulphur; a cardanol-based organic vulcanizing agent produced by means of the method; and a rubber compound and a tyre composition using the vulcanizing agent. The rubber composition using the cardanol-based organic vulcanizing agent of the present invention markedly improves estimated trip milage (FPS), tensile strength (T/S), unvulcanized characteristics and wet road surface grip characteristics as compared with using a conventional vulcanizing agent, and contributes to an improvement in actual vehicle wear performance in tyres that constitute an end product using same, and thus can advantageously be utilized in a blended rubber composition used in a rubber vulcanizing process for tyre treads.
