High-hardness mouldproof wallpaper base membrane and preparation technology thereof

Abstract

The invention discloses a high-hardness mouldproof wallpaper base membrane and a preparation technology thereof. The high-hardness mouldproof wallpaper base membrane is prepared from, by weight, 35-48 parts of polyvinyl alcohol, 20-28 parts of silicon-acrylate emulsion, 15-20 parts of glycidyl methacrylate, 16-18 parts of isocyanate, 15-20 parts of diisooctyl phenyl phosphite, 5-8 parts of sodium stearate, 5-8 parts of Arabic gum, 6-9 parts of gelatin, 5-8 parts of glycerol, 3-4 parts of sodium hexametaphosphate, 2-3 parts of ammonium persulfate, 11-18 parts of cortex phellodendri, 6-10 parts of coconut shells, 5-8 parts of flos caryophylli, 5-8 parts of Chinese pulsatilla roots, 4-6 parts of cortex magnoliae officinalis, 2-3 parts of herba violae, 2-3 parts of wrinkled gianthyssop herb, 1-2 parts of rheum officinale and 110-150 parts of deionized water. Hardness test results can show that the wallpaper base membrane has the high hardness and is helpful for wall face solidifying and pulverizing. Experiments prove that the wallpaper base membrane has a good long-term mouldproof effect.

Description

technical field [0001] The invention relates to a wallpaper base film, in particular to a high-hardness mildew-resistant wallpaper base film and a preparation process thereof, belonging to the technical field of wallpaper accessories. Background technique [0002] Before pasting the wallpaper, it is necessary to apply a layer of wallpaper base film. When the base film is brushed on the wall and waits for it to dry, a dense protective film will be formed. Its function is to isolate the wall, so that the wallpaper and the wall Isolated, do not let the wallpaper directly touch the wall, effectively prolonging the service life of the wallpaper, and at the same time providing convenience for the later replacement of the wallpaper. Most of the wallpapers are cement walls or painted walls, because cement walls and painted walls sometimes contain high alkalinity or pollution, and if the painted walls are not protected by a base film, the wallpaper will easily fall off. Even yellow....

Problems solved by technology

[0003] At present, chemical anti-mold agents are usually used to achieve the purpose of anti-mold, and the disadvantages are very obvious: high biological hazards, and the anti-mold effect is not ideal

[0004] Hardness is also an important indicator of wallpaper base film, which is directly related to the effect of curing the wall surface and improving the hardness of the wall surface. However, the hardness of the wallpaper base film in the current market often cannot meet daily needs.
