Abstract

The invention relates to water-soluble environmentally-friendly glue spray which is prepared from the following raw materials in percentage by weight: 7 to 10 percent of a polyurethane elastomer, 18 to 23 percent of water-based neoprene latex, 15 to 20 percent of water-based acrylic emulsion, 12 to 15 percent of ethylene-vinyl acetate copolymer emulsion, 1 to 4 percent of sodium dodecyl benzene sulfonate, 6 to 11 percent of a butadiene-styrene bromide copolymer, 1 to 3 percent of a water-based emulsifier, 6 to 12 percent of modified resin emulsion, 2 to 6 percent of a polyurethane associated thickener, 1 to 2 percent of a PH adjuster, 0.1 to 0.7 percent of a water-based defoaming agent and 8 to 15 percent of deionized water. No heating activation is needed, so that the water-soluble environmentally-friendly spray paint is environmentally-friendly, nontoxic, high in adhesive strength, high in drying speed, high in coating toughness, anti-freezing, flame-retardant and high in safety.

Description

technical field [0001] The invention belongs to the field of environment-friendly adhesives, and in particular relates to a water-soluble environment-friendly spray glue. Background technique [0002] Spray glue is a kind of adhesive with suitable viscosity, which can closely connect two different material interfaces and play the role of transfer application. It is widely used in furniture, leather and decoration industries. At present, the spray glue on the market is mainly solvent-based spray glue (oily spray glue). The spray glue sold on the market contains toxic or highly toxic solvents of triphenyls (benzene, toluene, xylene), which will cause poisoning to varying degrees during the use of the product, and seriously pollute the environment, such as toluene and chlorinated solvents, These organic solvents enter the air, seriously affecting people's living environment and damaging people's health. In addition, solvent-based spray glue also has the problem of being flamm...
