Abstract

The invention discloses a manufacturing method of a styrene-butyl acrylate-divinylpyridine emulsion, which comprises the following steps: (1) adding 0.6-0.9 part by weight of nonionic emulsifier and 0.5-0.8 part by weight of initiator into 200-300 parts by weight of deionized water, and uniformly mixing to obtain an emulsion A; (2) slowly adding 1-1.5 parts by weight of initiator into 50-100 parts by weight of deionized water, and uniformly mixing to obtain an emulsion B; (3) uniformly mixing 10-20 parts by weight of acrylic acid, 20-40 parts by weight of divinylpyridine, 80-120 parts by weight of butyl acrylate, 300-350 parts by weight of styrene, 150-200 parts by weight of deionized water, 2.5-3 parts by weight of anionic emulsifier, 2.5-3.5 parts by weight of nonionic emulsifier and 0.8-1.2 parts by weight of cationic emulsifier to obtain an emulsion C; and (4) dropwisely adding the emulsion B and the emulsion C into the emulsion A uniformly at the same time, and uniformly stirring to obtain the required styrene-butyl acrylate-divinylpyridine emulsion. According to the invention, the styrene-butyl acrylate-divinylpyridine emulsion is used for after finishing of fiber midsoles, so that the fiber midsoles have the functions of favorable elasticity, tearing resistance, favorable stiffiness and the like; and the styrene-butyl acrylate-divinylpyridine emulsion can replace part of an acrylic emulsion, thereby saving the cost.

Description

technical field [0001] The invention relates to the field of emulsions for post-finishing, in particular to a method for preparing a fenpropir emulsion. Background technique [0002] At present, the emulsions used in the finishing of shoe midsoles mainly include vinyl acetate emulsion, styrene-acrylic emulsion, styrene-butadiene latex and acrylic emulsion. After finishing and padding, the physical properties such as stiffness, tear resistance and elasticity of the shoe base material can be improved. . [0003] A kind of anti-radiation midsole shoe material involved in Chinese patent CN102934860A, it adds anti-radiation material to mid-sole shoe material, has antibacterial deodorization anti-radiation function, and the soaking material that it uses is styrene-acrylic emulsion. [0004] Another example is a kind of strong breathable fiber shoe midsole material and manufacturing method involved in Chinese patent CN101942743A. Afterwards, carboxylated styrene-butadiene emulsion...
