Abstract

The invention discloses self-decoloration type wallpaper base film convenient to construct and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing a color developing solution from a color developing substance, then slowly dropwise adding the color developing solution into a macromolecular emulsion, stirring and uniformly mixing, then adding an auxiliary agent, and stirring and uniformly mixing to obtain the self-decoloration type wallpaper base film convenient to construct, wherein the color developing substance is any one selected from 1-naphtholphthalein, thymol phenolphthalein, m-nitrotoluene or p-nitrotoluene. The wallpaper base film disclosed by the invention is colored during construction and disappears after the construction is finished, so that the phenomenon of missing brushing is reduced, the construction difficulty is greatly reduced, and the construction effect is ensured. The wallpaper base film is high in decoloration speed, complete decoloration can be achieved within 2 hours, and construction convenience is greatly improved.

Description

technical field [0001] The invention relates to a wallpaper base film, in particular to a self-fading wallpaper base film which is convenient for construction and a preparation method thereof. It belongs to the technical field of wallpaper accessories. Background technique [0002] Wallpaper base film is a professional anti-alkali, moisture-proof and mildew-proof wall surface treatment material, which can effectively prevent the moisture and alkaline substances from the construction base surface from seeping out, and prevent the wallpaper from returning to moisture, mildew and blackening and other adverse damages. The use of wallpaper and wallpaper base film is a common home decoration method. A variety of wallpapers with different colors and texture patterns can be matched with different decoration styles, which is very popular among people. [0003] The method of using the wallpaper base film is simple. First, use a paint roller to evenly roll the base film on the wall. A...
