The invention relates to a preparation method of a high-strength wet-skid-resistant tread rubber material, and belongs to the technical field of tread rubber materials. According to the technical scheme, the coated silicon carbide fiber is modified, the silicon carbide fibers are effectively filled into the material, the formed composite filler is a double-structure material, the unmodified silicon dioxide material has relatively high polarity; the polarity strength of the embedded and loaded coated silicon carbide fiber is greatly reduced due to the modification effect, and the composite material not only has strong polarity, but also has a weak polarity effect; the imidazole ring in the ionic liquid and siloxane on the surface of the white carbon black form a hydrogen bond to be furtherstably combined; the composite coated fibers are loaded into the white carbon black so that the surface polarity of the white carbon black is reduced, aggregation among white carbon black particles ishindered, the dispersity is improved, the interface interaction between the white carbon black and rubber is enhanced, rubber molecular chains adsorbed on the surface of the white carbon black are increased, the mechanical strength of the material is further improved and the wet skid resistance of the tread rubber material is improved.

    本发明涉及一种高强抗湿滑型胎面胶材料的制备方法,属于胎面胶材料技术领域。在本发明技术方案中,通过改性包覆的碳化硅纤维,使碳化硅纤维有效填充至材料内部,形成的复合填料为双结构材料,未改性的二氧化硅材料具有较强的极性,而嵌合和负载的包覆碳化硅纤维由于改性作用大幅降低其极性强度,使复合材料既具有强极性又具有弱极性效应,离子液体中的咪唑环与白炭黑表面的硅氧烷形成氢键进一步稳定结合,通过复合包覆纤维负载到白炭黑中,降低了其表面极性,阻碍了白炭黑颗粒间的聚集,分散性提高,白炭黑与橡胶的界面相互作用增强,白炭黑表面吸附的橡胶分子链增加,进一步提高材料的力学强度,提高胎面胶材料的抗湿滑性能。
