Problems solved by technology

[0004] Most of the wall covering products on the market at this stage also have anti-mildew function propaganda, which mainly uses silicon acrylic acid and other compounds to form a waterproof barrier on the surface of the wall covering to prevent the contact between the wall covering and moisture to achieve mildew resistance. Although the method reduces the chance of moldy wall coverings to a certain extent, it is fundamentally a temporary solution, not a permanent cure.

Abstract

The invention discloses a plant-fiber wall surface coating with antifungal and mould-proof functions. The plant-fiber wall surface coating is prepared from, by weight, 60%-90% of plant fibers and 10%-40% of water-soluble vegetable glue, and 0.1%-1.0% by weight of a silver inorganic antifungal agent is added. The plant-fiber wall surface coating has good wear resistance and crack resistance, and also has good antifungal and mould-proof performance.

Description

technical field [0001] The invention belongs to the field of wall surface coating materials, and relates to a plant fiber wall coating coating with antibacterial and antifungal functions. Background technique [0002] At present, wall decoration is mainly based on paint and wallpaper. Traditional paints and coatings have a high content of harmful substances and are very harmful to the human body. Although water-based paints have been used in the market today, the content of harmful substances has been reduced, but there is still a certain amount of free formaldehyde, which makes it take a period of time after the walls of the room are painted. It can only be lived after ventilation, and the color of the wall pattern is single, lacking in aesthetic feeling. Although the application of wallpaper can enrich the pattern and color of the wall, its cost is greatly increased, and after a long time of use, problems such as aging, discoloration, and difficulty in repairing after dam...
