Abstract

The invention discloses a CRHD-based high-permeability indoor inorganic environment-friendly coating and a preparation technology and a using method thereof, and relates to the field of coatings. Forsecondary environment pollution generated in the indoor decorative process, the high-permeability indoor inorganic environment-friendly coating is prepared from water, lithopone, nano calcium carbonate, nano-silver solution, negative ion powder, vinyl acetate, silicon dioxide, talcum powder, titanium dioxide, acrylic emulsion, glycerinum and the like. The high-permeability indoor inorganic environment-friendly coating has the advantages that a formed film is of a three-dimensional net-shaped structure, and the coating is large in adhesive force, resistant to water, washable, resistant to agingand excellent in performance; the coating has good elasticity, wall cracks can be made up, and the decorative effect can be improved; static electricity is resisted, dust is not likely to be attached, the coating prepared in an antiseptic and antimicrobial mode is bright and lasting in color, and the anti-fouling performance is high; the functions of removing indoor methanal and benzene, releasing negative ions, removing indoor secondary pollution, improving and purifying indoor air and the like are achieved, and the coating is environmentally friendly and is an upgraded green coating.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a high-permeability indoor inorganic environmental protection coating based on CRHD activity and a preparation process and a use method thereof. Background technique [0002] Interior wall coatings are latex paints for general decoration, which are divided into two categories: polyvinyl acetate emulsions and acrylic emulsions according to different substrates. Emulsion paint uses water as a diluent, which is a kind of paint that is convenient for construction, safe, washable, and has good air permeability. Most of the indoor and outdoor decorative materials supplied in the building materials market are organic materials or organic-inorganic composite materials. These materials contain a large amount of volatile organic compounds such as formaldehyde, benzene, xylene and other toxic substances, causing indoor environmental pollution and harming human health. The production and use of inor...
