Abstract

The invention discloses a method for preparing damp-proof wallpaper. The method includes (1), mixing dichloromethane, thickening agents, polyvinyl alcohol, propyl benzene latex, acrylic resin, carbon black, defoaming agents and polyaniline with one another to obtain waterproof coating; (2), carrying out preheating treatment on paper; (3), coating the waterproof coating on the paper after preheating treatment is carried out on the paper and heating and embossing the paper to obtain the damp-proof wallpaper. The method has the advantages that the damp-proof wallpaper has a characteristic of water impermeability and is environmentally friendly and harmless, and accordingly waterproof effects can be realized by the damp-proof wallpaper.

Description

technical field [0001] The invention relates to a wallpaper, in particular to a moisture-proof wallpaper and a preparation method thereof.
