Abstract

The invention discloses a high-stability wallpaper adhesive, and belongs to the field of chemical building materials. Diatomite, hexacyclic stone and the like are used for preparing a homogenizing material, a large amount of diatomite components exert a cation exchange property and are in exchange interaction with cations in an organic compound, the internal stability is improved, microcrystallinecellulose is used as a main component, 1-allyl-3-methylimidazolium chloride is used as an ionic solvent and p-dioxanone is used as a grafting monomer to prepare an amphiphilic fiber polymer material,and a hydrophilic shell is used for stabilizing and dispersing micelles and protecting contact between hydrophobic molecules and an environment medium, and has a good moisture resistance; a moisture-proof material is prepared by taking acrylamide, methyl methacrylate and the like as raw materials, so that a macromolecular polymer in an aqueous solution exceeds a certain mass concentration, hydrophobic portions are associated to form a dynamic three-dimensional network structure, a moisture-proof effect is stabilized, and the bonding strength of the wall adhesive is improved. The problem thatthe commonly used wallpaper adhesive at present is easy to damp and low in adhesion stability is solved.

Description

technical field [0001] The product of the invention belongs to the field of chemical building materials and relates to a high-stable wallpaper adhesive. Background technique [0002] In recent years, wallpaper has become the first choice as a decoration material to beautify the indoor environment, and wallpaper glue is widely used in the market as an adhesive for bonding wallpaper. Wallpaper glue can be divided into two types: wet glue and glue powder, both of which have their own advantages and disadvantages. Wet glue has high initial adhesion and good bonding performance. Even if it is bonded to some relatively thick wallpapers, it is not easy to warp; but wet glue is more troublesome to use, and it needs to be dissolved in water several times; Water brings inconvenience to storage and transportation. After being stored and frozen in winter, the glue-opening performance becomes poor, and the transportation cost is high. Wallpaper glue powder is an adhesive specially prep...
