Abstract

The invention relates to a high-grade adhesive for wallpaper and wall cloth. The adhesive is prepared from 45-60 parts by weight of waterborne polymer resin serving as a main material, and 30-50 parts by weight of filler, 0.2-0.7 part by weight of a thickening agent, 0.1-0.3 part by weight of a defoaming agent, 0.1-0.3 part by weight of a wetting and dispersing agent, 0.1-0.4 part by weight of a plasticizer, 0.5-1.0 part by weight of a stabilizer, 0.5-2.0 parts by weight of a thixotropic agent, 0.1-0.5 part by weight of a preservative and 2-20 parts by weight of deionized water which are taken as auxiliary materials. After the technical scheme is adopted, the adhesive facilitates construction, and has the advantages of being good in bonding force with a base material, water-resistant and alkali-resistant, good in durability, healthy and environment-friendly, and the like. By means of filler selection and grading optimization, the strength and weather resistance of the adhesive are improved. The stability of the adhesive is improved by means of other additives and formula optimization.

Description

technical field [0001] The invention belongs to the field of paint formulations, and relates to a high-grade wallpaper and wall cloth adhesive, in particular to an adhesive with high adhesive force and strong water resistance. Background technique [0002] At present, in the process of home decoration, wallpaper walls have been widely used, and wallpaper wall adhesives are essential. Due to the particularity of the wallpaper wall, the general requirement for the adhesive is that it has a greater polarity and can be better bonded. Heat resistance, water resistance, alkali resistance, and mildew resistance are the basic requirements for wallpaper and wall adhesives. At present, commonly used wallpaper wall adhesives include powder adhesives such as starch and its derivatives, cellulose and its derivatives, which are environmentally friendly, non-toxic, tasteless, reversible, instant, etc. Advantages, but it has a big lack in mildew resistance and water resistance. The other...
