Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a special high wear-resistant rubber material for tire treads. Background technique [0002] Tire tread refers to the layer where the outermost layer of the tire is in contact with the road surface and the surface is printed with patterns, which can make the tire have traction, buffer the impact and swing during driving, and prevent the cord layer from being cut and pierced. The rubber material used to make tire treads needs to have the following characteristics: (1) High wear resistance and fatigue resistance; (2) Good aging resistance; (3) High tensile strength, elasticity and toughness; (4) low heat generation when the vehicle is running. With the improvement of road conditions in our country and the development of expressways, the driving speed of automobiles has been greatly increased, and overloading is common. Users have put forward higher requirements for high t...
