Problems solved by technology

Organic solvent-based spray glue uses organic solvents as the dispersion medium and diluent. Organic solvents are easy to volatilize and spread into the air to pollute the environment. Some products contain toxic and harmful solvents such as benzene and dichloroethane, which are harmful to people's health. Harm; water-based spray glue is mainly water-based chloroprene, which requires special spraying equipment, and the cost of raw materials is high
The antifreeze performance of water-based spray glue is not as good as that of organic solvent-based spray glue, which limits its application range

Abstract

The invention provides an oil-in-water type environment-friendly spray adhesive and a preparation method thereof. The environment-friendly spray adhesive comprises 50-100 parts of an oil phase, 10-50parts of a compound emulsifier, 50-100 parts of deionized water, 1-2 parts of a defoaming agent, 1-3 parts of a plasticizer and 2-5 parts of a stabilizer, wherein the oil phase comprises 10-20 parts of thermoplastic styrene-butadiene rubber, 12-30 parts of tackifying resin and 100-230 parts of a mixed solvent; and the compound emulsifier comprises 6-18 parts of an anionic emulsifier and 2-6 partsof a nonionic emulsifier. The added plasticizer is environmentally friendly, the plasticizer and the stabilizer can improve the frost resistance and low-temperature stability of the oil-in-water typeenvironment-friendly spray adhesive, and the oil-in-water type environment-friendly spray adhesive product is moderate in viscosity, convenient to spray, high in initial adhesion and capable of completely replacing an existing solvent type spray adhesive.

Description

technical field [0001] The invention relates to an oil-in-water type environmental protection spray glue and a preparation method thereof. Background technique [0002] Spray glue is a type of adhesive that is sprayed on the surface of sponge, wood, leather and other materials to play a bonding role. Spray glue is divided into organic solvent spray glue and water-based spray glue. Organic solvent-based spray glue uses organic solvents as the dispersion medium and diluent. Organic solvents are easy to volatilize and spread into the air to pollute the environment. Some products contain toxic and harmful solvents such as benzene and dichloroethane, which are harmful to people's health. Harm; water-based spray glue is mainly water-based neoprene, which requires special spraying equipment, and the cost of raw materials is high. The antifreeze performance of water-based spray glue is not as good as that of organic solvent-based spray glue, which limits its application range. Co...
