Tire tread rubber with low rolling resistance

Abstract

The invention relates to tire tread rubber with low rolling resistance, belonging to the technical field of a tire rubber formula. The tire tread rubber comprises 2-5 parts of natural rubber, 3-6 parts of styrene-butadiene rubber, 0.1-0.5 part of phenolic resin, 1-2 parts of epoxy resin, 2-4 parts of stearic acid, 2-4 parts of wax, 1-3 parts of an anti-aging agent, 21-35 parts of carbon black N330, 2-7 parts of white carbon black, 0.5-1 part of sulfur, 1.5-2.5 parts of an accelerating agent, 15-35 parts of aromatic oil and 4-15 parts of hard clay. By virtue of reasonable formula combination, the proportion of carbon black in the system is reduced, the rolling resistance of a finished product of a tire in use can be greatly reduced, and the wear resistance of the tire tread can not be influenced.

Description

technical field [0001] The invention relates to a tire compound, more specifically, the invention relates to a low rolling resistance tire tread compound, which belongs to the technical field of tire compound formula. Background technique [0002] Tires are circular elastic rubber products that are rolled on the ground and rolled on various vehicles or machinery. Usually installed on the metal hub, it can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubb...
