Abstract

The invention discloses a preparation method of environment-friendly wallpaper. The method comprises the steps that 1, acetone, a dispersing agent, polyvinyl chloride, melamine-formaldehyde resin, acrylic resin, silicon carbide, a defoaming agent and bamboo charcoal powder are mixed to prepare waterproof paint, wherein the weight-average molecular weight of polyvinyl chloride ranges from 80,000 to 90,000; 2, preheating treatment is conducted on paper; 3, the waterproof paint is applied to the paper subjected to preheating treatment, heating and embossing are conducted, and then the environment-friendly wallpaper is prepared. The environment-friendly wallpaper prepared through the method has the impermeable characteristic, can achieve the waterproof effect and is environmentally friendly and harmless.

Description

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