Abstract

The invention relates to a low heat generation and high wear-resistant white carbon black / rubber composite material and its preparation method and application. The rubber composite material includes rubber, white carbon black, silane coupling agent, and functional additives, and other commonly used materials can also be added. auxiliary agent, wherein the functional auxiliary agent contains at least one of cardanol polyoxyethylene ether sulfide and mercapto-containing cardanol polyoxyethylene ether compound. In the rubber composite material provided by the present invention, a silane coupling agent and a functional auxiliary agent are used in common, and the obtained rubber composite material has lower rolling resistance and heat generation, and compared with the existing white carbon black-filled sizing material, has Better wear resistance and lower compression fatigue temperature rise provide broad application prospects for the application of silica in tire tread rubber.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a low heat generation and high wear resistance white carbon black / rubber composite material and its preparation method and application. Background technique [0002] With the advancement of the automobile industry, people have more stringent requirements on the performance of tires. Filling rubber with silica, the prepared silica / rubber composite material has excellent properties such as low rolling resistance and low heat generation in the application of tire tread rubber. Performance, but its wear resistance is poor, especially in all-steel truck tires based on natural rubber, which severely limits the application of silica as a filler in tires. [0003] Coupling agent is a commonly used rubber additive in the manufacture of "green tires". The polysulfide bond or mercapto functional group contained in it can form a chemical bond with the rubber molecular chain, and th...
