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.
