Problems solved by technology

Traditional paint wall materials include lime milk and putty powder, which are cheap and environmentally friendly. However, slaked lime needs to be matured in the early stage, which takes a long time and is easy to pulverize in the later stage, which affects the practicality.
The main components of putty powder are talcum powder and glue. Most of the glue contains harmful substances such as free formaldehyde. After a certain period of use, the viscosity of latex will begin to age, pulverize, and fall off. In addition, since latex is a polymer polymer There will be adverse effects such as dampness and mildew
Wallpaper wall materials have a beautiful appearance, and you can choose the color according to your preferences; but the bottom layer is putty powder, which also has the problem of putty powder, and there will be air bubbles, swelling, mildew in the later stage, and the bonding edge is easy to warp during the construction process. The phenomenon of poor wear resistance

Abstract

The invention relates to a wall coating which comprises the following components in parts by mass: slurry which is prepared from the following components in parts by mass: 90-110 parts of sodium silicate, 0.4-0.6 part of copper sulfate, 0.32-0.88 part of sodium carbonate, 0.32-0.44 part of ferrous sulfate, 0.64-0.88 part of aluminum potassium sulfate, 0.32-0.88 part of sodium chloride, 0.1-0.3 part of calcium superphosphate, 0.1-0.5 part of potassium permanganate, 0.32-0.88 part of boric acid, 0.1-0.3 part of urea, 10-30 parts of water, and the powder material which comprises coarse whiting and Portland cement in a weight ratio of (0-0.5):1. Specific components are mixed according to a specific ratio and have a synergistic effect, so that the wall coating is relatively good in early strength, relatively high in hardness and relatively strong in base surface cohesiveness, and the problems of moisture regain, mildewing, bubble generation and falling of a traditional wall material are effectively solved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel high-tech environment-friendly wall paint and its preparation method and application. Background technique [0002] Wall material refers to the material applied to the wall for protection and decoration, and is an indispensable part of building decoration materials. Wall materials can be divided into mud, paint, wallpaper, wall covering, artificial decorative board, stone, ceramic, glass, metal and so on. Traditional paint wall materials include lime milk and putty powder, which are cheap and environmentally friendly. However, slaked lime needs to be matured in the early stage, which takes a long time, and it is easy to pulverize in the later stage, which affects the practicality. The main components of putty powder are talcum powder and glue. Most of the glue contains harmful substances such as free formaldehyde. After a certain period of use, the viscosity o...
