A kind of air-purifying diatomite interior wall decoration powder coating and preparation method thereof

Abstract

The invention relates to the field of paints, and discloses an air-purification diatomite internal wall decoration powder paint and a preparation method thereof. The powder paint comprises 40-50 parts of diatomite, 10-20 parts of meerschaum, 10-20 parts of air purification particle, 6-10 parts of silica sol, 4-6 parts of Portland cement, 4-6 parts of hyacinth bletilla powder, 1-2 parts of carboxymethyl cellulose, 1-2 parts of phenoxy resin, 0.5-1.5 parts of glutaric dialdehyde, 0.5-1.5 parts of chitosan, 0.5-1.5 parts of defoaming agent and 0.5-1.5 parts of dispersing agent. The air-purification diatomite internal wall decoration powder paint has the advantages of favorable water resistance, high adsorption capacity, long purification time efficiency and favorable air purification effect, and has the air purification function. The powder paint has favorable antibacterial and mildewproof actions.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an air-purifying diatomite interior wall decoration powder 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, diatom mud coatings on the market are gradually popularized b...

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
