Method for producing high performance tread rubber using ionic liquid as in-situ catalyst for silanization reaction of filler

摘要

In the present invention, raw rubber, filler, silane, and ionic liquid are sequentially put into an open kneader or a closed kneader to obtain a kneaded rubber, and the kneaded rubber is turned over at a high temperature. A vulcanized bag and an anti-aging agent are added to the kneaded rubber after turning over at room temperature, and the kneaded rubber is vulcanized to obtain a vulcanized rubber. The ionic liquid is used as an in situ catalyst for the silanization reaction of the filler. A method for producing a performance tread rubber is disclosed. The method of the present invention improves the rubber-filler interface performance by effectively promoting the dispersion of light-color fillers such as white carbon black in rubber by using an ionic liquid as a filler surface silanization catalyst. The amount can be greatly reduced, the dynamic characteristics of the tread rubber material can be greatly improved, the rolling resistance and dynamic heat generation can be reduced, the process is simple, no additional processing equipment or steps are added It can be used for manufacturing high-performance tires.
