Embodiment 1

[0033] A high-performance anti-ski tire tread compound, comprising 45 parts of natural rubber, 55 parts of high-cis butadiene rubber, 15 parts of special synthetic polymer, 20 parts of carbon black, and 35 parts of white carbon black in parts by weight , 18 parts of softener, 5 parts of active agent, 2 parts of lubricant, 5.5 parts of coupling agent, 5.25 parts of anti-aging agent and 3 parts of vulcanizing agent,

[0034] The special synthetic polymer adopts Lanxess M750H.

[0035] Its preparation method comprises the following steps:

[0036] The first master refining process:

[0037] (1) Add natural rubber, high cis-butadiene rubber, special synthetic polymer, coupling agent, carbon black and silica, press the top bolt to mix the rubber material, the mixing time is 30-40 seconds, and the mixing time is 30-40 seconds. The speed is 40-45 rpm, the mixing temperature is 110-120°C;

[0038] (2) Add softener and lubricant, press the top bolt to continue mixing, the mixing tim...

Embodiment 2

[0055]It is basically the same as Example 1, the difference is that: high-performance anti-ski tire tread compound, in parts by weight, includes 40 parts of natural rubber, 60 parts of high cis-butadiene rubber, 16 parts of special synthetic polymer, carbon 18 parts of black, 33 parts of white carbon black, 15 parts of softener, 6 parts of active agent, 1.5 parts of lubricant, 5.3 parts of coupling agent, 5.5 parts of anti-aging agent and 2.5 parts of vulcanizing agent.

Embodiment 3

[0057] It is basically the same as that of Example 1, except that the high-performance anti-ski tire tread compound comprises 50 parts by weight of natural rubber, 50 parts of high-cis butadiene rubber, 17 parts of special synthetic polymer, carbon 20 parts of black, 38 parts of white carbon black, 16 parts of softener, 5.5 parts of active agent, 2.5 parts of lubricant, 6.1 parts of coupling agent, 5.5 parts of anti-aging agent and 3.2 parts of vulcanizing agent.

Abstract

The invention relates to high-performance antiskid snow tire tread rubber and a preparation method thereof. The high-performance antiskid snow tire tread rubber is composed of, by weight, 40-55 parts of natural rubber, 45-60 parts of high-cis butadiene rubber, 15-18 parts of special synthetic polymer, 18-22 parts of carbon black, 33-40 parts of white carbon black, 15-20 parts of softener, 4-6 parts of active agent, 1.5-2.5 parts of lubricant, 5.3-6.4 parts of coupling agent, 5-5.5 parts of antiager and 2.5-3.5 parts of vulcanizing agent. The high-performance antiskid snow tire tread rubber is low in hardness, high in elasticity, low in rubber vitrification temperature, still capable of maintaining soft at low environment temperature, high in wear resistance and high in icy and snowy road holding performance, and slipping on icy and snowy roads is avoided effectively, so that car accidents are avoided, and traveling safety is improved.

Description

technical field [0001] The invention relates to a high-performance anti-ski tire tread compound and a preparation method thereof, belonging to the field of tire rubber. 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. Cars are prone to traffic failures on ice and snow roads in winter, and the requirements for anti-skid tires used in winter are getting higher and higher. The market lacks high-performance anti-ski tires. The existing snow tires are relatively hard overall, that is, the tread is relatively hard, and the grip and anti-skid performance on ice and snow roads are not ideal, and the safe handling performance on ice and snow roads cannot be...
