Abstract

The invention relates to the field of coatings, and discloses environment-friendly polyvinyl acetate emulsion paint and a preparation method thereof. The emulsion paint comprises the following components in parts by mass: 40-50 parts of polyvinyl acetate emulsion, 4-6 parts of kaolin, 1-2 parts of phenoxy resin, 2-4 parts of bletilla striata powder, 1-3 parts of corn starch, 0.25-0.75 part of glutaraldehyde, 2-4 parts of air purification particles, 0.04-0.06 part of a thickening agent, 0.04-0.06 part of a defoaming agent, 0.04-0.06 part of a dispersing agent and 35-45 parts of water. The environment-friendly polyvinyl acetate emulsion paint provided by the invention has an air purification function, is large in adsorption capacity, long in water purification lasting time and good in air purification effect, and meanwhile is relatively good in filming property, water resistance and soiling resistance.

Description

Technical field [0001] The invention relates to the field of coatings, in particular to an environment-friendly polyvinyl acetate latex paint and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, they are paying 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 during decoration. [0003] In the process of interior decoration, wood boards, glue, wall coatings, and furniture contain more or less harmful substances such as formaldehyde and benzene series. They will gradually be emitted in the years or even decades after decoration, thereby affecting the human body. health. At present, the water-based coatings on the market do not contain organic solvents, so they are more en...
