Antiviral coating and preparation method thereof

Abstract

The invention relates to the field of interior wall coatings, and particularly discloses an antiviral coating and a preparation method thereof. The antiviral coating is prepared from the following components in parts by weight: 6 to 10 parts of polyurethane emulsion, 1 to 3 parts of water, 1.5 to 2.5 parts of pigment filler, 0.5 to 1 part of antibacterial agent, 1 to 3 parts of auxiliary agent, 1.2 to 2 parts of antiviral porous microspheres and 0.1 to 0.5 part of polyphosphate; the antiviral porous microspheres are prepared from the following components in parts by weight: 0.5 to 1 part of activated carbon, 0.8 to 1.2 parts of a traditional Chinese medicine extracting solution, 1 to 1.5 parts of polylactic acid, 0.5 to 0.8 part of silicon dioxide sol, 0.3 to 0.7 part of carbon nanotubes and 0.2 to 0.5 part of zinc pyrithione. The antiviral coating disclosed by the invention has the advantages of being capable of resisting viruses and degrading formaldehyde under a weak light or dark condition, strong in stain resistance and good in antibacterial property and light stability.

Description

technical field [0001] The application relates to the technical field of interior wall coatings, more specifically, it relates to an antiviral coating and a preparation method thereof. Background technique [0002] With the gradual deterioration of the environment, the immune mechanism of the human body is gradually weakened, resulting in a gradual increase in the number of people who suffer from viral infections each year. Studies have shown that 80% of common infections (such as colds, flu, diarrhea, etc.) are actually caused by contact with infected people. Spread by contaminated surfaces. When touching a surface, hands come into contact with up to 50 percent of the microbes on the surface, and after touching the mouth, eyes and nose, the human body can become infected with these microbes. [0003] With the improvement of consumers' living standards, the demand for products with antiviral functions is increasingly urgent. Coatings are in close contact with consumers dai...

AI Technical Summary

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventors found that the interior wall paint has the effect of degrading harmful gases in the air and killing bacteria and viruses under the irradiation of ultraviolet rays due to the addition of photocatalytic fillers, but the photocatalytic fillers It is only active under ultraviolet or visible light, cannot be effectively used under low light conditions, and takes a long time to produce antiviral effects
