Abstract

The invention discloses a rubber composition for tires. The rubber composition comprises the following components in parts by weight: 8-15 parts of butadiene rubber, 3-9 parts of zinc stearate, 4-6 parts of silicon dioxide, 3-9 parts of sodium acetate, 2-6 parts of ammonium polyphosphate, 5-10 parts of poly-4-methyl-1-amylene, 5-10 parts of an active agent, 2-7 parts of a peroxide vulcanization agent, 1-5 parts of zinc oxide, 3-6 parts of a vulcanization promoting agent TT, 1-3 parts of a filling agent, 4-9 parts of kieselguhr and 1-4 parts of a silane coupling agent. The rubber composition for tires has the beneficial effects of good wearing resistance, good strength and high acid-alkali resistance and oxidation property.

Description

technical field [0001] The present invention relates to a rubber composition for tires. Background technique [0002] As an important part of the car, the car tire is an important part of the car to bear gravity, transmit traction force, braking force, steering force and bear the reaction force of the road surface. Its quality is directly related to personal and property safety. In order to improve the grip performance of the tire rubber composition, people use natural rubber modified rubber, wherein epoxy natural rubber is widely used. However, when epoxy natural rubber is used to make automobile tires, since epoxy natural rubber is prone to thermal aging and vulcanization reduction, the performance of the tire gradually deteriorates during use. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a rubber composition for tires, which has good wear resistance, good stren...
