Two-component water-soluble environment-friendly spray gel and method for preparing same

Abstract

The invention provides two-component water-soluble environment-friendly spray gel and a method for preparing the same. The spray gel comprises the following components in part by weight: a component A: 60 to 80 parts of water-borne polychloroprene latex, 20 to 30 parts of acrylic acid latex, 20 to 30 parts of ethylene-vinyl acetate copolymer latex and 2 to 10 parts of sodium dodecyl benzene sulfonate; a component B: 5 to 20 parts of modified rosin latex, 1 to 5 parts of isocyanate, 5 to 10 parts of polyurethane association-type thickening agent, 2 to 8 parts of clay, 0.2 to 0.8 part of water-borne defoaming agent and 20 to 30 parts of deionized water; and the mass ratio of the component A to the component B is (3-6):1. The two-component water-soluble environment-friendly spray gel of the invention has the advantages of no organic solvents, no heavy metals, no smell, high bonding initial adhesion, quick drying, excellent heat resistance and anti-ageing property and the like; and the spray gel can be used for bonding not only leather, sponges or non-woven fabrics in same materials, but also sponges and wood, sponges and non-woven fabrics and wood and non-woven fabrics, so that the scope of application of water-borne spray gel in industries of furniture, decoration and leather is widened.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a two-component water-soluble environmental protection spray glue and a preparation method thereof. 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). Solvent-based spray glue contains a large amount of organic solvents, such as toluene and chlorinated solvents, and even contains carcinogenic ingredients such as benzene. 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 flammable and explosive, which frequently causes fires. Therefore, countries a...

Problems solved by technology

[0003] However, the applicant found that the current water-based spray glue on the market can only realize the bonding between sponges of the same material, but cannot realize the bonding between sponge and wood, sponge and non-woven fabric, wood and non-woven fabric. The bonding between, thus, limits the scope of use of water-based spray adhesives in the furniture and decoration industry
