Problems solved by technology

You can't pursue environmental protection and ignore stickiness, or pursue stickiness and ignore environmental protection
Otherwise, it may cause harm to the user's health
[0004] The wallpaper adhesives on the market are mainly starch-based adhesives. This type of adhesive has better bonding performance, but the service life is not long
If the adhesive strength of the wallpaper adhesive is not enough, the edges and corners will naturally warp after a long time; however, the wallpaper used in commercial facilities has strong adhesion, and the edges and corners will still warp after a period of use. In fact, it is not because of construction or wallpaper The problem, many reasons are out of the glue
Everyone knows that the decoration cycle of commercial places is shorter than that of home decoration, but this kind of problem still occurs. The problem lies in the glue. The weather resistance and waterproof performance of this kind of wallpaper glue are generally poor. After being oxidized in a humid environment, it is easy to deteriorate and pulverize, thus losing its bonding effect. The organic components contained in some starch-based adhesives will also oxidize and deteriorate after absorbing water and denaturing, turning black and moldy
[0005] Therefore, how to improve the bond strength, waterproof and anti-mildew properties of wallpaper glue has become an important research topic; the invention patent authorization announcement number CN102965053B announced a preparation method of sulfoethyl-carboxymethyl-crosslinked starch-based wallpaper glue, Although this technical solution improves the bonding performance and drying speed of the wallpaper glue through a special starch modification process, the problems of the colloid being easy to age and fall off and easy to oxidize and mold are still unsolved.

Abstract

The invention relates to the technical field of adhesives, in particular to high-viscosity mildew-proof wallpaper glue. The wallpaper glue includes the components of aqueous polyurethane resin, nano calcium carbonate, a composite tackifier, polyvinyl alcohol, chitosan, a mildew inhibitor, a bacteriostatic agent, a defoamer and deionized water, wherein the composite tackifier is a special composition prepared by compounding mucopolysaccharide, modified cellulose, modified starch and other substances, and the mildew inhibitor is one selected from 1,2-benzisothiazole-3-one, methyl isothiazolinoneand 5-chloro-2-methyl-4-isothiazolin-3-one; and the defoamer is polyoxyethylene polyoxypropanolamine ether or polydimethylsiloxane or polyoxypropylene polyoxyethylene glyceryl ether, and the bacteriostatic agent is a nano silver antibacterial finishing agent. The wallpaper glue has the advantages of excellent bonding performance, good anti-aging performance, long service life, outstanding anti-oxidation and an outstanding anti-mildew effect.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-viscosity anti-mildew wallpaper glue. Background technique [0002] With the improvement of the economic level, people's requirements for the living environment are getting higher and higher, which promotes the rapid development of the home improvement industry. Among home improvement materials, wallpaper is a widely used interior decoration material. Because wallpaper has many advantages such as various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and reasonable price, these are unmatched by other interior decoration materials. Therefore, wallpaper is popular in developed countries and regions such as Europe, America, Southeast Asia, and Japan. It has been widely used. At present, domestic interior decoration also uses a large number of decorative wallpapers. Wallpaper usually uses bleached chemical wood pulp to...
