Efficient wallpaper base film

Abstract

The invention discloses an efficient wallpaper base film, prepared by mixing the following components by weight percent: 15-20 parts of water, 5-8 parts of ethylene glycol, 65-75 parts of emulsion, 1-2 parts of a dispersing agent and 1-2 parts of a modifying agent. The efficient wallpaper base film is made from environmental protection materials, thus not producing formaldehyde. The silicone acrylic emulsion used in a formula of the efficient wallpaper base film is capable of effectively permeating into a putty layer so as to solidity a wall. In addition, hydroxyethyl methyl cellulose ether is added into the efficient wallpaper base film, so that the constructability of the base film is effectively improved, a phenomenon of splashing is avoided, and the base film is enabled to be evenly painted. Furthermore, the drying time of the base film can be controlled to be 2-3 hours (surface dry), so that the emulsion is enabled to have enough time to permeate into the wall for solidifying the wall.

Description

technical field [0001] The invention relates to the technical field of wallpaper auxiliary materials, in particular to a high-efficiency wallpaper base film. Background technique [0002] The wallpaper base film is developed from water-based polymer materials, which is harmless to the human body and has no harmful gas volatilization to the environment. Compared with the use of traditional oily alkyd varnishes, it effectively protects the indoor environment and is more effective than oily alkyd varnishes. The life span is extended three to five times. The function of wallpaper base film: solidify the base layer (putty layer), prevent mold growth, better connect the wallpaper and 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. [0003] When the ordinary wallpaper base film is painted with a roller, it is prone ...

Problems solved by technology

[0004] The purpose of the present invention is to address the shortcomings of the existing wallpaper base film, and provide a wallpaper base film that solves the problem of splashing, sagging, and uneven painting when the base film is painted, and the drying time of the base film on the wall surface after brushing is appropriate. Effectively controls the drying time of the base film, which is conducive to the penetration of the base film into the putty layer and solidifies the wall
