Multifunctional paint and preparation method thereof

Abstract

The invention relates to the field of paints and discloses a multifunctional paint and a preparation method thereof. The paint is prepared from the following components in percentage by mass: 15-50% of a composite filler, 4-10% of a color-change factor, 0.5-2% of an anti-freezing agent, 35-65% of an emulsion, 0.3-0.5% of a wetting agent, 0.5-2% of an antifoaming agent, 0.2-1% of a thickener, 0.5-2% of a neutralizer, 0.2-1% of an antimycotic agent, 0.4-1% of a dispersing agent, 0.5-1.5% of a coalescing agent, 3-5% of a reducing liquid and the balance of water, wherein the composite filler contains the following components in parts by weight: 5-15 parts of silicate neodymium crystal, 1-10 parts of tourmaline powder, 15-25 parts of calcined diatomite and 1-5 parts of indium-containing rare earth; the thickener contains a cellulose thickener and a polyurethane thickener; and the weight ratio of the cellulose thickener to the polyurethane thickener is 1:(2-4). The harmful gases of formaldehyde and the like in air are absorbed to the surface and the inside of a coating through the calcined diatomite in the multifunctional paint and then effective components of the reducing liquid in the coating are decomposed, meanwhile, anions are released by the tourmaline powder, so that targets of improving the air quality and optimizing the indoor environment are achieved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a multifunctional coating and a preparation method thereof. Background technique [0002] At present, there are various materials for decorating interior walls on the market, usually including the following: ordinary latex paint, wallpaper, wall covering, tile marble, diatom mud and so on. Among them, the function of latex paint is single, and the stain resistance is generally deviated; although wallpaper and wall covering solve the problem of single color tone, the construction process is complicated, the joints are not beautiful, and it is easy to mold when exposed to water. Release formaldehyde and other harmful substances to the human body; although tiles and marble have solved the problem of stain resistance, the use of such decorative materials on the inner wall has the problems of high decoration cost, unsightly appearance, and poor environmental protection, resulting in consumptio...

AI Technical Summary

Problems solved by technology

Among them, the function of latex paint is single, and the stain resistance is generally deviated; although wallpaper and wall covering solve the problem of single color tone, the construction process is complicated, the joints are not beautiful, and it is easy to mold when exposed to water. Release formaldehyde and other harmful substances to the human body; although tiles and marble have solved the problem of stain resistance, the use of such decorative materials on the inner wall has the problems of high decoration cost, unsightly appearance, and poor environmental protection, resulting in consumption are less accepting of

However, the recently popular new decoration materials such as diatom mud have poor pollution resistance, and after absorbing harmful substances, there is a risk of continuing to release harmful substances.
