Problems solved by technology

There are a wide variety of decoration and decoration materials on the market. Although most of the materials can meet people’s requirements for the aesthetics of the living room, artificial panels such as rubber plywood and decorative panels, adhesives such as urea-formaldehyde resin, phenolic resin, and formaldehyde resin, and various impregnated materials on the market , wall paint, wallpaper, floor, chemical fiber carpet and other decorative materials are inseparable from formaldehyde. The formaldehyde contained in the decorative material itself, as well as the harmful gases such as formaldehyde released later, are very harmful to human health.

Abstract

The invention belongs to the technical field of building materials for decoration, and particularly relates to a pasty diatom ooze, which is prepared from the following materials in parts by weight: 50 to 80 parts of diatomite, 50 to 80 parts of titanium dioxide, 20 to 30 parts of chitosan, 20 to 30 parts of expanded perlite, 10 to 15 parts of methylcellulose, 40 to 60 parts of sodium alginate, 10to 20 parts of glycerol and 150 to 180 parts of water. The pasty diatom ooze prepared by the invention has a large specific surface area, can adsorb formaldehyde and other harmful gases in the air, and also has the capability of heat insulation, fireproofing and air humidity regulation. When the pasty diatom ooze is used for substituting for conventional wallpapers and latex paint, under the premise of ensuring exquisite appearance, the indoor air can be purified as well.
