The invention relates to the field of rubber, and discloses rubber modified masterbatch, tire tread rubber and a preparation method of the rubber modified masterbatch and the tire tread rubber. The rubber modified masterbatch contains a modifier, benzoyl peroxide, a matrix material, white oil, long-chain fatty acid and microcrystalline wax; wherein the base material is one or more of a polyolefin elastomer, ethylene propylene diene monomer and an ethylene-vinyl acetate copolymer. According to the rubber modified masterbatch provided by the invention, the white carbon black has better dispersity in a rubber matrix, and the interaction between the white carbon black and the rubber matrix is stronger, so that the strength of vulcanized rubber can be better improved, the heat generation of the vulcanized rubber is reduced, and the wet skid resistance is improved.

    本发明涉及橡胶领域,公开了一种橡胶改性母胶和轮胎胎面胶及其制备方法。所述橡胶改性母胶含有改性剂、过氧化苯甲酰、基体材料、白油、长链脂肪酸和微晶蜡;其中,所述基体材料为聚烯烃弹性体、三元乙丙橡胶和乙烯‑醋酸乙烯酯共聚物中的一种或多种。本发明提供的橡胶改性母胶可使白炭黑在橡胶基体中有更好的分散性,白炭黑和橡胶基体的相互作用更强,从而能够更好地提高硫化橡胶的强度,降低其生热,以及提高抗湿滑性。
