The invention relates to the field of rubber, and discloses a rubber processing modifier, a preparation method and application thereof, a tire tread rubber composition, tire tread rubber and a preparation method thereof. The rubber processing modifier comprises a mercapto acid monomer, a matrix material and white carbon black, the sulfydryl acid series monomer is provided by at least one of compounds shown in a formula (1): # imgabs0, the rubber processing modifier comprises the sulfydryl acid series monomer, a matrix material and white carbon black, and the sulfydryl acid series monomer, the matrix material and the white carbon black are mixed in advance to prepare the rubber processing modifier; according to the present invention, the rubber processing modifier can significantly improve the compatibility and the dispersibility of the mercapto acid monomer and the rubber matrix, and when the rubber processing modifier is used for preparing the tire tread rubber, the heat generation and the rolling resistance of the tire tread rubber can be significantly reduced on the premise of ensuring the high strength, the high wear resistance and the high wet skid resistance of the tire tread rubber.

    本发明涉及橡胶领域,公开了橡胶加工改性剂及其制备方法与应用、轮胎胎面橡胶组合物、轮胎胎面胶及其制备方法。该橡胶加工改性剂包含巯基酸系单体、基体材料和白炭黑;所述巯基酸系单体由式(1)所示的化合物中的至少一种提供:#imgabs0#该橡胶加工改性剂包含巯基酸系单体、基体材料和白炭黑,预先将巯基酸系单体与基体材料以及白炭黑混合制备得到橡胶加工改性剂,能够显著改善巯基酸系单体与橡胶基体的相容性以及分散性,将该橡胶加工改性剂用于制备轮胎胎面胶时,能够在保证轮胎胎面胶具有高的强度、耐磨性和抗湿滑性的前提下,显著降低轮胎胎面胶的生热和滚动阻力。
