Problems solved by technology

From the main composition point of view, the existing wallpaper glue is mainly grain-based with starch, Ma Ling potato flour and glutinous rice flour as raw materials. The grain-based wallpaper glue has good adhesion and no formaldehyde. These are substances containing protein and nutrients. Once it is wet and damp, it is easy to grow mold, and it decays quickly, becoming a medium for mold. Therefore, the glue made of this food base material is used for wallpapering. Once damp and moldy, the wallpaper will turn yellow, black, bulge, warp, and even be pierced due to corrosion.
[0004] In addition, as interior decoration materials, wallpaper glue is prepared from organic raw materials, so it also needs to have a certain flame retardant performance, which has not been reflected in the prior art

Abstract

The invention relates to an environment-friendly wallpaper adhesive and a preparation method thereof. The environment-friendly wallpaper adhesive comprises an agent A and an agent B, wherein the agent A is prepared by processing the following raw materials in parts by weight: 60-80 parts of modified defatted soybean meal paste, 6-8 parts of water-soluble glucan, 4-6 parts of leveling agent, 2-3 parts of organic bentonite and 1-3 parts of assistant which is a mixture of at least two of flame-retardant powder, nano negative ion powder and antistatic agent; the component B is prepared by processing the following raw materials in parts by weight: 8-15 parts of propolis powder, 1-3 parts of antioxidant, 30-40 parts of substrate, 1-2 parts of emulsifier, 40-60 parts of 75-85% of ethanol solvent by volume and appropriate pH regulator; the substrate is any one of natural rubber, vitamin derivative and modified starch; the pH of the agent B is 6-8. In the environment-friendly wallpaper adhesive provided by the invention, the raw materials of the agents A and B are reasonably selected and in proper compatibility; compared with existing glue, the prepared adhesive has the advantages of excellent water resistance and gluing property, good uniformity in drying, high flatness and excellent antibacterial property, antistatic property and flame retardance.

Description

technical field [0001] The invention relates to an environment-friendly wallpaper adhesive and a preparation method thereof, belonging to the technical field of building decoration materials. Background technique [0002] Wallpaper, also known as wallpaper, is a widely used interior decoration material. Because wallpaper has the characteristics of various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and reasonable price, etc., it has become a popular home decoration product and is more and more popular among people. . [0003] During the decoration process, wallpaper needs to be pasted to the wall with glue. The effect of wallpaper paving is also the embodiment of the overall decoration effect. The basic function of wallpaper glue is to stick wallpaper for a long time. From the main composition point of view, the existing wallpaper glue is mainly grain-based with starch, Ma Ling potato flour and glutinous rice flour ...
