In the production mode of “natural rubber + styrene-butadiene rubber + reclaimed rubber + carbon black”, the carbon particles in carbon black have strong adsorption, and the adhesion to rubber molecules is very good. Large gel, which increases the hardness, strength and wear resistance of the tire tread rubber, effectively improves the wear resistance and wet skid resistance of the rubber tire tread; but the agglomerate and friction formed by the action of carbon black and rubber Large, so the rolling resistance is large, only nano-scale carbon black can improve this defect, to some extent reduce the rolling resistance of car tires.
