Document Type and Number:
WIPO Patent Application WO/2021/047087
Kind Code:
A1
Abstract:
Provided is a preparation method for resin for improving wet skid resistance of rubber, the first step: subjecting R resin and B functional group compound to a reaction, to obtain R-B resin and improve degree of polymerization of R resin; wherein R resin is selected from C9 petroleum resin, C5 petroleum resin, α-methylstyrene homopolymer resin, DCPD resin, terpene resin, pinene resin or copolymerized resin based on α-methylstyrene as a principal chain, B functional group compound is selected from phenol, cardanol, ethylidene norbornene (ENB), rosin, hexa methoxy melamine resin (HMMM) or divinylbenzene; the second step: subjecting R-B resin to a reaction with S silane, to obtain R-B-S resin. The prepared resin is used for being added into the rubber, can be effectively dispersed inside the rubber and is distributed in tire tread during vulcanization, which remarkably improves the wet skid resistance of the rubber.
