The invention discloses a tire tread rubber composition and a preparation method thereof, and the tire tread rubber composition is prepared from polyisoprene rubber, polybutadiene rubber, styrene-butadiene copolymer, 3, 3 '-trimethyl-1, 3, 4-trimethyl-1, 3, 4-trimethyl-1, 3, 4-trimethyl-1, 3 The anti-aging rubber is prepared from 1, 4-isoprene rubber, carbon black, white carbon black, vinyl tri (beta-methoxyethoxy) silane, sodium cocoyl monoglyceride sulfate, aromatic oil, an anti-aging agent 4020, an anti-aging agent RD, microcrystalline wax, stearic acid, zinc oxide, sulfur, an accelerant TMTD and an accelerant ZDC. By using the 3, 4-isoprene rubber, the dry traction performance and the wet skid resistance of the rubber material can be improved, and the mechanical property and the wear resistance of the rubber material are improved by improving the dispersion of white carbon black in the rubber material through the mutual cooperation of the vinyl tri (beta-methoxyethoxy) silane and the sodium cocoyl monoglyceride sulfate, so that optimization and improvement are performed; finally, the tire tread rubber composition with excellent performance is designed, and the tire tread rubber composition not only has excellent mechanical properties, but also has excellent traction performance, wet skid resistance, wear resistance and durability.
本发明公开了一种轮胎胎面橡胶组合物及其制备方法,其由聚异戊二烯橡胶、聚丁二烯橡胶、苯乙烯‑丁二烯共聚物、3,4‑异戊橡胶、炭黑、白炭黑、乙烯基三(β‑甲氧基乙氧基)硅烷、椰油酸单甘油酯硫酸酯钠、芳烃油、防老剂4020、防老剂RD、微晶蜡、硬脂酸、氧化锌、硫磺、促进剂TMTD、促进剂ZDC制成。本发明通过3,4‑异戊橡胶的使用可以提高胶料干地牵引性能和抗湿滑性,胶料的力学性能和耐磨耗性能的改善是通过乙烯基三(β‑甲氧基乙氧基)硅烷和椰油酸单甘油酯硫酸酯钠相互配合改善胶料中白炭黑的分散,从而进行优化和完善,最终设计出性能优越的轮胎胎面橡胶组合物,不仅具有优异的力学性能,还具有优异的牵引性能、抗湿滑性能、耐磨耗性能和耐久性能。
