Abstract

The invention discloses an environment-friendly building coating and a preparation method thereof. The coating comprises, by weight percentage, 10-16% of styrene-acrylic emulsion, 22-30% of modified resin emulsion, 4.2-6.8% of titanium dioxide nano-powder photocatalyst, 2.2-3.8% of rigid polyurethane foam powder, 5-15% of N-butyl vinyl ether, 2.5-6.9% of antifoaming agent, 0.2-0.6% of thickening agent, and the balance deionized water. The titanium dioxide nano-powder photocatalyst is added based on an existing indoor building coating to improve performances of the building coating in decomposing harmful microorganisms and harmful gas; N-butyl vinyl ether is added so that the catalytic effect of the titanium dioxide nano-powder photocatalyst can be greatly improved, and the harmful microorganism decomposition capability of the coating is enhanced.

Description

technical field [0001] The invention relates to an environment-friendly architectural paint and a preparation method thereof. Background technique [0002] Traditional latex paints for interior walls of buildings need to add a large amount of organic solvents such as antifreeze and film-forming aids in the paint, resulting in a high content of volatile organic compounds in the paint. In addition, in order to prevent corrosion and deterioration of the paint during storage and coating If the film is moldy, it is necessary to add a large amount of organic anti-mold fungicides that are harmful to the human body in the paint. This not only directly affects the physical and mental health of the occupants, but also has timeliness. After a period of time, it loses the anti-mold effect. In interior decoration, since wooden furniture, plywood and other woods and solvent-based wood paints will release a large amount of organic volatiles such as formaldehyde and benzene that are highly ...
