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

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...
