Abstract

The invention discloses an adsorption and purification enhanced colored rock sheet inner wall coating with porous starch with synergic honeycomb-shaped manganese dioxide. Prepared from corn starch in modes of extrusion and enzymolysis, the porous starch has a large specific surface area and a specific volume and is honeycomb-shaped, so that the adsorption property is remarkably improved; meanwhile with addition of the honeycomb-shaped manganese dioxide which is added into the coating in a synergic manner, the adsorption property can be very good, PM2.5, particle impurities and the like in air can be adsorbed, and meanwhile an effect of formaldehyde catalytic oxidation can be achieved; the colored rock sheet inner wall coating disclosed by the invention is attractive in appearance, good in weather resistance, good in pure water property, safe and non-toxic and worthy of popularization since indoor environments can be purified, a healthy and comfortable indoor environment can be provided for people and development requirements of granite-imitated inner wall coatings can be met.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a multi-colored rock slice interior wall coating with enhanced adsorption and purification of porous starch and honeycomb manganese dioxide. Background technique [0002] Water-based composite rock flake imitation granite paint is also called rock flake paint and granite stone paint. It is a new type of pure water-based sand wall-shaped architectural paint that does not contain any solvent-based substances. It is rich in the style of granite, the connotation of granite, the nobility of granite, and the grade of granite. , is an upgraded variety of traditional natural stone paint. With the wide application of new coatings in the construction market, the research on the formulation of composite rock slices in architectural coatings has attracted more and more attention from researchers. Water-based composite rock flake imitation granite paint is prepared from high-quality synthet...
