Abstract

The invention belongs to the field of wallpaper accessories and particularly relates to a nano-silver wallpaper primer which is prepared by mixing the following raw materials in part by weight: 350 to 415 parts of deionized water, 10 to 15 parts of ethylene glycol, 0.5 to 1 part of nano-silver, 0.5 to 1 part of pH control agent, 100 to 200 parts of transparent adhesive, 250 to 350 parts of odorless latex, 8 to 10 parts of film-forming adjuvant, and 6 to 8 parts of alkali-swelling thickener. The nano-silver wallpaper primer product can inhibit the growth of bacteria on the surface of a wall body and prevent mildew of wallpaper, increases the density of the wall surface, solves the problems of wall body chalking and water molecule lateral seepage, and keeps the pH of the wall body balanced to ensure that the pH value of the wall surface trends to be neutral.

Description

technical field [0001] The invention belongs to the field of wallpaper auxiliary materials, and in particular relates to a nano-silver wallpaper base film and a preparation method thereof. Background technique [0002] The function of the base film: solidify the base layer (putty layer), prevent mold growth, better connect the wallpaper and the base layer, and facilitate secondary stickers. The method of using the base film is very simple: use a paint roller to evenly roll the base film on the wall. After the base film is dry, you can paste the wallpaper. Ordinary wallpaper base film will produce moisture reaction when brushed on the wall, which will lead to mildew of wallpaper, affect the appearance of wallpaper, and even affect the health of users. Contents of the invention [0003] The invention mainly solves the problem that in the past decoration process, the ordinary wallpaper base film will produce a wet reaction when brushed on the wall surface, resulting in milde...
