Problems solved by technology

The toluene solution of trichloroisocyanuric acid can have a good bonding effect after treating TPR, but it is unstable and needs to be prepared temporarily, and it is easy to make the surface of the material turn yellow and affect the appearance.
Li Weiguang developed a TPR material surface treatment agent prepared with methyl methacrylate and graft copolymer solution with SBS rubber [Adhesive, 2002, 23 (3) 19], in which toluene is a moderately toxic Solvents can accumulate in the human body, long-term exposure can cause respiratory diseases, neurological diseases and even leukemia, etc., causing serious harm to the health of workers in production and use

Abstract

The invention relates to a preparation method of a maleic anhydride containing TPR (Thermal Plastic Rubber) surface treating agent. The method comprises the following steps of: preparing SBS (Styrene Butadiene Styrene) grafted maleic anhydride copolymer emulsion and chlorinated polypropylene grafted copolymer emulsion; uniformly agitating 100 parts by weight of SBS grafted maleic anhydride copolymer emulsion, 20 to 80 parts by weight of chlorinated polypropylene grafted copolymer emulsion, and 10 to 15 parts by weight of polyvinylpyrrolidone, so as to obtain the water-based surface treating agent for the TPR sole material. According to the preparation method, the SBS grafted maleic anhydride copolymer emulsion and chlorinated polypropylene grafted copolymer emulsion are compounded, and the obtained water-based surface treating agent shows high compatibility with the TPR material because of maleic anhydride and chlorinated polypropylene, also shows a good effect on surface treating of the TPR material, meets the adhering requirements of the shoes manufacturing industry, and also realizes the requirements on green and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a preparation method of a surface treatment agent, in particular to a preparation method of an aqueous surface treatment agent for a TPR sole material used with a shoe adhesive in cold-bonded shoemaking. Background technique [0002] Thermoplastic elastomer (also known as thermoplastic rubber) is made of symmetrical block styrene-butadiene rubber (SBS rubber) as the main body and processed with other materials. It is a polymer material with high elasticity and can be plasticized at high temperature. It is also the so-called third-generation rubber after natural rubber and synthetic rubber, abbreviated as TPR. Because of its wear resistance, easy processing and low price, it is widely used as The sole material, especially the middle and high-grade sports sole material. However, due to its weak polarity, in the cold-bonded shoe industry, in order to improve the bond...
