Abstract

The invention discloses special rubber used for a snow tire. The special rubber is prepared from the following components in parts by weight: 50-70 parts of natural rubber, 30-40 parts of butadiene rubber, 10-20 parts of epichlorohydrin rubber, 25-45 parts of carbon black N330, 15-20 parts of carbon black N339, 12-18 parts of white carbon black, 5-8 parts of silane coupling agent Si75, 2-5 parts of zinc stearate soap, 2-5 parts of aromatic hydrocarbon oil, 0.5-1.5 parts of anti-aging agent H, 1-3 parts of bi-2,4, 1-3 parts of bi-2,5, 1-2 parts of accelerator TT, 1-2 parts of accelerator D and 1-2 parts of accelerator NS. The special rubber used for the snow tire has the advantages of low Tg value, good tensile strength, elongation and rebound resilience, high road holding at a low temperature and excellent cold endurance.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to a special rubber for snow tires. Background technique [0002] Snow tires are tires specially designed for use in winter conditions, such as icy climates and regions with lower temperatures. Cars driving on snowy roads require tires with stronger braking performance, grip performance and handling performance due to the slippery road surface and low driving resistance. Due to the poor cold resistance of ordinary tires, the hardness of the tires increases and the elasticity decreases under the low temperature of winter snowy days, resulting in the loss of working ability and safety. Contents of the invention [0003] The purpose of the present invention is to address the above problems, and propose a special rubber for snow tires, which can still maintain considerable toughness and elasticity at low temperatures, has high grip at low temperatures, excellent comprehensive performan...
