Problems solved by technology

[0004] The purpose of the present invention is to improve the existing water-based polyurethane glue, to provide an adhesive for environmental protection shoes, which overcomes the low initial viscosity, slow drying rate, poor water resistance and solvent resistance of the latex film in common water-based polyurethane adhesives, The defects of low gloss and poor comprehensive performance of the coating film can greatly improve the initial tackiness, coating property, drying property and adhesiveness of the coating film of the water-based polyurethane adhesive for shoes.

Abstract

The invention discloses an environment-friendly water-based adhesive for shoes, prepared from the following components: modified casein, polyacrylate, caprolactam, water-dispersing polyisocyanates, sodium carboxymethylcellulose, amino resin, functional auxiliaries, dodecyl trimethyl ammonium chloride, sodium diethylhexyl sulfosuccinate, dodecylbenzene sulfonic acid and a curing agent. The environment-friendly adhesive for the shoes overcomes the defects that a common water-based polyurethane adhesive is poor in first viscosity, slow in drying rate, poor in water resistance and solvent resistance of a latex film, lower in glossiness, and poorer in comprehensive performance of a coating film, so as to achieve the aim of greatly improving the first viscosity, coating property, drying property and adhesion of a coating film of the water-based polyurethane adhesive for the shoes.

Description

technical field [0001] The invention relates to an adhesive, in particular to an environmentally friendly water-based adhesive for shoes. Background technique [0002] 95% of my country's shoemaking industry uses neoprene adhesives, and there are relatively few companies using water-based polyurethane. Because neoprene adhesives have good initial viscosity, cold stickiness, cheap price, and usage habits, etc., many enterprises choose low price. neoprene. However, its performance is not resistant to the penetration of plasticizers, and it has poor adhesion to new shoe materials such as soft PVC, thermoplastic rubber, and PU leather. In addition, the benzene that must be used is a toxic solvent, which is a fatal weakness and seriously endangers the health of employees. Health, has not adapted to the requirements of the development of the shoe industry. [0003] my country is a big shoe-making country, producing more than 10 billion pairs every year. Adhesives for shoes have ...
