Problems solved by technology

However, there are still many disadvantages in the current coatings that use activated carbon as the main air purification component: 1. The adsorption capacity of activated carbon is small, and the general effective duration of adsorption is 1 year, while the release of harmful gases is long-term, so it cannot meet the long-term requirements. Air purification requirements; 2. Activated carbon has good hygroscopicity. While adsorbing harmful gases, it will also absorb a large amount of water, resulting in its limited adsorption capacity being occupied

Abstract

The invention relates to the field of coatings and discloses a water-tolerant flavor purification type polyvinyl alcohol water-soluble coating and a preparation method thereof. The coating comprises the following components in parts by mass: 5-15 parts of polyvinyl alcohol, 10-20 parts of calcium carbonate, 4-6 parts of talcum powder, 1-3 parts of phenoxy resin, 2-4 parts of rhizoma bletillae powder, 1-3 parts of corn starch, 0.5-1.5 parts of glutaraldehyde, 1-3 parts of air purification particles and 55-65 parts of water. The water-tolerant flavor purification type polyvinyl alcohol water-soluble coating has an air purification function and a good air purification effect and is relatively good in water tolerance, large in adsorption capacity and long in purification timeliness.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-resistant and deodorizing polyvinyl alcohol water-soluble coating and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to their own health. In recent years, reports on the relationship between newly renovated indoor air pollution and the incidence of leukemia have also been seen in the media. Therefore, people pay more and more attention to the environmental protection of decoration materials when decorating. [0003] In the process of interior decoration, harmful substances such as formaldehyde and benzene series are more or less contained in wood boards, glue, wall paint, and furniture, which will gradually emit in the years or even decades after the decoration, thus affecting the health of the human body. healthy. At present, the water-based coatings on the market are more enviro...
