Study on the Effect of Carbon-White/Carbon Black Filling on Wear Resistance of Tread

摘要

This paper studied the law of the wear resistance of tread rubber, by adding different parts of the rubber material (NR, BR9000, SBR-1502), carbon black and Carbon-White. The results show that the abrasion resistance, grip and rolling resistance of the three kinds of rubber materials are slightly different. The wear resistance of BR9000 is the best and the grip performance of SBR1502 is the best. With the increase of carbon black, the wear performance is reduced and the wear resistance is increased. When the adding amount is increased to more than 60 parts, the grip performance is obviously improved and the wear resistance and mechanical properties are not significantly increased. The addition of silica can make the rolling resistance Lower, while the wet grip performance, wear resistance has little effect.
