Abstract

The invention discloses an alcohol-soluble decorative adhesive and a preparation method thereof, belonging to the field of an adhesive. The adhesive is prepared from the following components in percentage by weight: acrylate polymer, tackifying resin and solvent, wherein the acrylate polymer is polymerized from 20-50wt% of acrylate hard monomer, 40-70wt% of acrylate soft monomer and 1-10wt% of acrylate functional monomer by a solution polymerizing method under the actions of an initiator and the solvent. The glass transition temperature of the acrylate polymer is -10 to -40 DEG C. As the acrylate hard monomer and the acrylate soft monomer are reasonably matched, and a certain acrylate functional monomer is matched to participate into the polymer, the molecular chain of the acrylate polymer in the decorative adhesive has multiple chemical bond structures of -COH, -OH, -NH and the like, multiple intermolecular action force can be formed, the adhesive can be adhered to various composite materials with good adhesion property and wide adhesion range. The decorative adhesive can use the alcohol as the main solvent and has the advantages of little toxicity and low cost.

Description

technical field [0001] The invention belongs to the technical field of adhesives, in particular to an alcohol-soluble decorative adhesive and a preparation method thereof. Background technique [0002] Due to the large gap between my country's economic level, industrial structure, and living habits and foreign countries, the amount of solvent-based adhesives in my country is still relatively large. Most of the decorative glues used in my country are neoprene and SBS (styrene-butadiene-styrene) type decorative glues, which contain a large amount of toxic solvents such as benzene and xylene, which are very harmful to the human body . Home decoration, wood processing, leather products and other industries are major users of decorative adhesives. Every year, about 100,000 tons of organic solvents in decorative adhesives volatilize into the atmosphere to pollute the environment, which not only causes certain damage to human health, but also has harmful effects on the atmosphere. ...
