[0030] The preparation method is the same as in Example 1.

Embodiment 3

[0032] Raw material components: 16 parts of silicone rubber, 18 parts of EPDM rubber, 8 parts of polyvinyl chloride, 5 parts of lead phosphite, 20 parts of hydrogenated nitrile rubber, 2 parts of rubber vulcanizing agent, 20 parts of highly dispersed white carbon black, 5 parts of nano-zinc oxide, 7 parts of coupling agent, 6 parts of tackifying resin, 2 parts of accelerator NOBS, 1 part of accelerator CZ, 5 parts of aromatic oil, and 2 parts of anti-aging agent H.

[0033] The preparation method is the same as in Example 1.

[0034] Adopt the main technical index in the tire of the rubber composition that embodiment 1-embodiment 3 makes and common tire comparative experiment:

[0035]

[0036]

[0037] The present invention carries out running test through the tire of the rubber composition that embodiment 1-embodiment 3 makes, and this tire is compared with common tire, runs on the glass surface that has water smoothly, and brake does not skid and does not "discharge"....

Abstract

The invention discloses an antiskid wear-resistant tire composition and a preparation method thereof. The antiskid wear-resistant tire composition is prepared from the following raw materials in parts by mass: 14-16 parts of silicon rubber, 12-18 parts of ethylene propylene diene monomer rubber, 4-8 parts of polyvinyl chloride, 2-5 parts of lead phosphite, 16-20 parts of hydrogenated butadiene-acrylonitrile rubber, 1-2 parts of rubber vulcanizer, 10-20 parts of high-dispersity white carbon black, 1-5 parts of nano zinc oxide, 5-7 parts of coupling agent, 4-6 parts of tackifying resin, 1-2 parts of accelerator NOBS, 0.5-1 part of accelerator CZ, 2-5 parts of aromatic oil and 1.3-2 parts of anti-aging agent H. The preparation method comprises the following steps of compounding, rubber sheet cooling, weight compounding and the like. The tire prepared from the composition has favorable wet grip ability, favorable dry grip ability and favorable wear resistance.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to an anti-skid and wear-resistant tire composition used in automobiles and a corresponding preparation method thereof. Background technique [0002] Tires are one of the most important components of a car. Its main function is to support the entire weight of the vehicle, bear the load of the car, transmit traction and braking torque, and ensure the adhesion between the wheel and the road. Most of the tires are rubber material. With the development of automobiles in the direction of high speed, safety, energy saving, and comfort, the requirements for high performance tires are also increasing year by year, which puts forward higher requirements for tires' wet skid resistance and wear resistance. [0003] The existing ordinary tires are poor in wet skid resistance, and the road surface is easy to slip in rainy days, causing serious safety hazards. Improve its wear resistanc...
