Preparation method of negative ion formaldehyde-removing water-based paint

Abstract

The invention discloses a preparation method of a negative ion formaldehyde-removing water-based paint, wherein the preparation method comprises the steps: mixing potassium tungstate powder with negative ion powder slurry to form a negative ion stock solution; dissolving an amino-containing raw material in water to form an amino-rich formaldehyde removal stock solution; respectively adding the negative ion stock solution and the amino-rich formaldehyde removal stock solution into water, and mixing to form a negative ion formaldehyde removal solution; and adding the negative ion formaldehyde removal solution into a water-based paint with the mass ratio of the negative ion formaldehyde removal solution being 10-30% to obtain the negative ion formaldehyde removal water-based paint. The preparation and use raw materials are environmentally friendly and convenient to use, harmful gas can be oxidized and decomposed from the source, the negative ion emission function and the formaldehyde removal liquid can form a functional synergistic effect, the improvement of the formaldehyde removal efficiency can be facilitated, and meanwhile the air quality of furniture and public places can be improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of functional water-based paints, and in particular relates to a preparation method of anion-removing aldehyde water-based paints. Background technique [0002] Harmful gases in the air seriously affect people's normal work and life. For some newly decorated furniture and relatively airtight places, such as building basements, parking lots, shopping malls, factory workshops, these places urgently need a material with air purification function and green environmental protection. [0003] At present, related products on the market, such as photocatalyst technology, are relatively mature. Under the irradiation of light, especially short-wave light such as ultraviolet rays, light energy can be converted into chemical energy, and odorous gases can be quickly decomposed. It also has a bactericidal effect, but at night or without ultraviolet radiation The efficiency will be greatly reduced, which li...

Problems solved by technology

[0003] At present, related products on the market, such as photocatalyst technology, are relatively mature. Under the irradiation of light, especially short-wave light such as ultraviolet rays, light energy can be converted into chemical energy, and odorous gases can be quickly decomposed. It also has a bactericidal effect, but at night or without ultraviolet radiation The efficiency will be greatly reduced, which limits its scope of application. At the same time, the compounding technology of this product and water-based paint needs to be further improved.

Another way is to add some adsorption materials to the water-based paint, such as activated carbon and diatomaceous earth materials. This material has a large specific surface area due to its porous structure. The small pores can lock harmful gases so that they cannot diffuse and be absorbed. Adsorbed on the surface of the material and in the internal pores, this method has an obvious effect in a short period of time, but because it cannot decompose the odor molecules from the source, the effect will no longer be obvious when the adsorption saturation is reached, even when the ambient temperature changes. becomes a release source, and in order not to affect the effect of water-based paint, the amount of adsorbent material added is very limited
