The invention provides a mixing method for reducing agglomeration of white carbon black in a rubber matrix. A rubber composite material is composed of the following raw materials in parts by weight: raw rubber, white carbon black, a silane coupling agent Si-69, N234 carbon black, an accelerant DPG, a rubber additive and a vulcanizing agent. The invention further provides a preparation method of the rubber composite material containing the white carbon black, the invention provides the mixing method for improving agglomeration of the white carbon black in the rubber matrix, the problems of agglomeration and secondary agglomeration of the white carbon black in the rubber matrix are solved, and the modification effect of the silane coupling agent Si-69 on the surface of the white carbon black is improved. Therefore, the extrusion process performance of the rubber composite material with high content of white carbon black is improved, and the problem of low reinforcing efficiency of the white carbon black is solved.

    本发明提供一种降低白炭黑在橡胶基体中团聚的混炼方法,由如下重量份数的原料组成:生胶,白炭黑,硅烷偶联剂Si‑69,N234炭黑,促进剂DPG,橡胶助剂,硫化剂。本发明还提供一种含有白炭黑的橡胶复合材料制备方法,本发明提供了一种改善白炭黑在橡胶基体中团聚的混炼方法,改善白炭黑在橡胶基体中的团聚及二次团聚问题,提高硅烷偶联剂Si‑69对白炭黑表面的改性的效果。从而改善高含量白炭黑的橡胶复合材料的压出工艺性能及改善白炭黑补强效率低的问题。
