Problems solved by technology

There is no doubt that formaldehyde is toxic to humans, especially if formaldehyde is used in the glue, the release of formaldehyde is very slow after this type of glue is used indoors, and free formaldehyde can be detected in the indoor environment even after several years. The existence of formaldehyde can cause irreversible harm to people. It is now clear that many human diseases

Abstract

The invention relates to bletilla striata glue wallpaper powder and a preparation method thereof. The bletilla striata gum wallpaper powder is preapred by compounding raw materials including, in partsby weight, starch, bletilla striata gum superfine powder, xanthan gum, carboxymethyl cellulose sodium, filler and borax; wherein the water absorption rate of the wallpaper powder in a humid environment is effectively reduced, and the bletilla striata gum wallpaper powder is good in waterproof performance, high in cohesiveness and good in mildew-proof and antibacterial capacity and has good application prospects. Therefore, mildewing and deterioration in a humid environment are avoided, the stability is good, and the service life is long.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to white glue wallpaper powder and a preparation method thereof. Background technique [0002] Baiji bulbs contain a large amount of water-soluble polysaccharides, and its chemical composition is glucomannan, which is the main functional component of Baiji gum. Baijijiao has a certain thickening effect. [0003] 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 c...
