Problems solved by technology

[0006] Interior wall architectural coatings are in close contact with our daily life, and the coatings have a large coating area and a wide range, which is very suitable as a carrier for absorbing formaldehyde gas. The adsorption of formaldehyde gas by coatings prepared in the prior art mainly depends on physical adsorption. fillers, such as activated carbon, acid algae earth, medical stone, etc., but physical adsorption has its own adsorption saturation problem, and the harmful gases that were originally adsorbed may be desorbed and released into the environment again, which will also create new safety hazards. health hazard

Abstract

The invention relates to the field of building material preparation, in particular to a method for preparing an interior wall paint with the function of eliminating formaldehyde; the water-based interior wall paint prepared by the invention has the ability to eliminate indoor formaldehyde and other harmful gases, and the paint of the invention is a A non-toxic, low-pollution, high-performance, energy-saving and functional coating; a silicon-based nickel-containing straw material is added to the coating of the present invention, which has the advantages of strong adsorption capacity for indoor harmful gases such as formaldehyde. Under the light, through photocatalyst catalysis, indoor harmful gases such as formaldehyde can be efficiently degraded into carbon dioxide and water, avoiding the adsorption saturation problem of physical adsorption; the invention is a functional environmental protection material that improves the healthy environment of indoor air.

Description

technical field [0001] The invention relates to the field of building material preparation, in particular to a method for preparing an interior wall paint with the function of eliminating formaldehyde. Background technique [0002] As one of the most important indoor air pollutants at present, formaldehyde is highly irritating, highly toxic and volatile. When in contact with the human body, it will not only irritate the skin, mucous membranes and respiratory tract, but even cause hereditary genotoxicity. Long-term exposure can cause skin or respiratory diseases such as asthma or allergies to the human body, and it can induce cancer in severe cases. This also makes formaldehyde the second highest priority control chemical in my country. [0003] CN105797565A relates to a formaldehyde adsorption plate, including an aquifer, the aquifer is soaked with an aqueous solution of amino acids, the aquifer is wrapped with a porous layer, and the porous layer is wrapped with a breathabl...
