Abstract

A disclosed rubber composition used for manufacturing a tire tread is characterized by comprising the following compositions in parts by weight: 30-50 parts of emulsion-polymerized styrene butadiene rubber, 10-25 parts of polybutadiene rubber, 10-20 parts of environment-friendly aromatic oil, 10-20 parts of H-resin, 3-8 parts of high dispersive white carbon black, 5-10 parts of cis-1,4-polybutadiene rubber, 3-5 parts of protective wax, 2-5 parts of an inorganic foaming agent, 1-5 parts of an activator, and 1-5 parts of a curing agent. The rubber composition possesses excellent wet slip resistance and bulging resistance and high wet-land grabbing force, a tire prepared from the rubber composition is endowed with balance performances such as tire wet-land grabbing force, rolling resistance and wear resistance, and also the rubber composition helps to improve wear resistance, tear resistance, and chunking and piece-drop resistance of the tire tread.

Description

Technical field [0001] The invention relates to a rubber composition for manufacturing tire treads, belonging to the technical field of tire manufacturing. Background technique [0002] As an important part of automobiles, automobile tires are important components for automobiles to bear gravity, transmit traction, braking force, steering force, and bear road reaction forces. Their quality is directly related to personal and property safety. Internationally, it is customary to divide car tires into passenger car tires and light truck tires (LightTruck Tire), in addition to truck and bus tires (Truck&Bus Tire); and according to the different tire process structures, they are divided into bias tires (Bias). ) And radial tires (Radil), and radial tires are divided into two types: all-steel and semi-steel. Generally speaking, trucks and bus radial tires with specifications above 9.00 are called all-steel radial tires, and trucks, bus tires and cars with specifications below 9.00 are ...
