Problems solved by technology

[0002] Nowadays, many people choose to paste wallpaper for interior decoration. The patterns on the wallpaper make the wall more beautiful. However, most of the wallpapers on the market are made of PVC materials. The wallpaper is pasted on the wall by brushing glue on the wall. Wallpaper It is difficult to remove after sticking, and it will damage the wall after being forcibly removed. The wallpaper is difficult to paste, and it is easy to appear air bubbles, which is difficult to repair. After the glue volatilizes, it will affect and harm human health. The characteristics of the material make the wallpaper easy to become dull and yellow after use, which affects the appearance of the interior

Abstract

The invention discloses a manufacturing method of environmental-protection polyurethane wall paper. The manufacturing method comprises the following steps: uniformly mixing 80-100 parts of polyurethane surface layer resin, 40-70 parts of organic solvent, 0.5-2 parts of assistant and 5-8 parts of environmental-protection toner, so as to obtain a dry-method surface material; uniformly mixing 80-100 parts of polyurethane bonding resin, 20-60 parts of organic solvent, 0.5-2 parts of assistant and 5-8 parts of environmental-protection toner, so as to obtain a dry-method bonding material; coating the dry-method surface material on a release paper pattern, thus obtaining a PU surface dry film, coating the dry-method bonding material on the PU surface dry film, bonding a piece of wall surface bottom paper on the dry-method bonding material when the organic solvent is volatilized to 40-80%, drying, cooling, and then separating the release paper, so as to obtain the environmental-protection polyurethane wall paper. The wall paper prepared according to the manufacturing method has the characteristics of brilliant color, the environmental-protection materials are not likely to volatilize toxic substance, so that the wall paper does not affect the health of a human body, and is especially suitable for home decoration and hotel decoration.
