Abstract

The invention discloses a formula of a snow tire. The formula of the snow tire comprises the following components: 5-15% of natural rubber, 20-40% of solution polymerized styrene butadiene rubber, 15-30% of high abrasion proof carbon black N234, 10-20% of high dispersion white carbon black, 0.5-1% of a peptizer A-8, 0.5-1.5% of a chemical antioxidant 6PPD, 0.5-1.5% of a physical antioxidant microcrystalline wax, 1-3% of an active agent ZNO, 1-3% of an active agent SA, 0.5-1.5% of polyethylene glycol (PEG), 1-3% of a vulcanizing agent S-325, 0.5-1.5% of an accelerant CZ, 0.1-0.5% of a special agent CTP and 4-8% of a coupling agent SI69. The technical scheme provided by the invention has the beneficial effects of low hardness and good elasticity of tire surface glue, low vitrification point of rubber, high wear resistance, good road holding performance on ice and snow covered pavement; therefore, the snow tire can effectively avoid skidding on ice and snow covered pavement, and enhance road safety.

Description

technical field [0001] The invention relates to a tire tread formula and a preparation method thereof, in particular to a snow tire formula and a preparation method thereof. Background technique [0002] Ordinary tires come to winter, especially under the conditions of perennial ice and snow weather in the north, as the temperature decreases, the hardness of the tread rubber increases and the elasticity decreases. The stability is greatly reduced, the grip is reduced to the minimum, and it will slip on ice and snow roads, leading to car accidents. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a snow tire formula and a preparation method thereof. The tread rubber has low hardness, good elasticity, low glass transition temperature of rubber, and can still maintain softness at lower ambient temperatures. High wear resistance, good grip on ice and snow roads, effectively avoid ski...
