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 surface treatment agent formulated with methyl methacrylate and a graft copolymer solution with SBS rubber to promote the adhesion of TPR soles [Adhesion, 2002, 23 (3) 19], in which toluene It is a moderately toxic solvent that 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 method for preparing maleic anhydride-containing polymer emulsion. The method comprises the following steps: adding toluene, butanone, ethyl acetate, methyl methacrylate, maleic anhydride and SBS rubber into a reaction kettle for stirring, and controlling the temperature to be 60-70 DEG C; introducing nitrogen, raising the temperature to 80-90 DEG C, adding benzoyl peroxide and an acrylic monomer solution for polymerizing for 3-5 hours by adopting a dripping mode, lowering the temperature to 50-60 DEG C, performing reduced pressure distillation to remove 50-80% of solvent, adding a neutralizer until the pH value of the system is 6.5-8.5, and reacting for 0.5-1 hour; gradually adding deionized water at high-speed stirring, and finally adding polyvinylpyrrolidone for uniformly stirring, and obtaining the maleic anhydride-containing polymer emulsion used for surface treatment of TPR sole materials. The maleic anhydride-containing polymer emulsion prepared by the method has an obvious adhesion promotion effect on the TPR material and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of polymer emulsion synthesis, and relates to a preparation method of a material surface treatment agent, in particular to a preparation method of a maleic anhydride-containing polymer emulsion used for surface treatment of TPR sole materials in cold-bonded shoemaking. Background technique [0002] Thermoplastic elastomer (also known as thermoplastic rubber), which is made of symmetrical block styrene-butadiene rubber (SBS rubber) as the main body and processed with other materials, is a kind of rubber with both rubber and thermoplastic properties. It shows rubber at room temperature. 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. It is abbreviated as TPR. Because of its easy processing and low price, it is widely used as sole material. Especially middle and high-grade sp...
