Abstract

The invention discloses a stretch-proof tire rubber material and a preparation method thereof. The stretch-proof tire rubber material is mainly prepared from the following components in parts by weight: 60 parts of natural rubber, 20-40 parts of butadiene styrene rubber, 15-35 parts of peroxyacetic acid, 15-25 parts of carbon nano tubes, 10-20 parts of nano aluminia, 40-60 parts of carbon black, 1-7 parts of ethylene-vinyl acetate copolymer, 3-7 parts of a coupling agent, 0.5-1.5 parts of zinc dimethyl dithiocarbamate, 10-20 parts of silicon dioxide and 5-15 parts of a vulcanizing agent. Compared with the prior art, the stretch-proof tire rubber material and the preparation method thereof have the advantages that process is simple, cost is low, the advantages of the rubber material in the prior art are maintained, and stretch-proof property of the rubber material can be further improved.

Description

technical field [0001] The invention relates to a stretch-resistant tire rubber material and a preparation method thereof, belonging to the technical field of tire rubber materials. Background technique [0002] With the development of the automobile industry and the improvement of people's quality of life, people's requirements for automobile safety, comfort and speed, as well as environmental protection requirements, promote the continuous improvement of the automobile industry and determine the development direction of pneumatic tires. Tire is the safety part of the car. As the medium between the car and the road surface, its performance has a direct impact on the power, fuel economy, braking, handling stability, ride comfort and off-road performance of the car. The correct selection of tires can ensure the best performance of the car. The current general trend of the world's tire development comes down to "three in one", that is, the radialization, flattening and tubele...
