Abstract

The invention provides scrubbing-resistant shell powder paint for efficiently decomposing formaldehydes. The scrubbing-resistant shell powder paint is characterized by being prepared from the following ingredients in parts by weight: 100 parts of shell powder, 0.1 to 1 part of fired shell powder 0.1 to 1 part of nanometer titanium dioxide, 13 to 22 parts of emulsion powder, 0.01 to 0.1 part of zinc oxide, 0.5 to 2 parts of rare earth antibacterial agents and 0.1 to 1 part of silica sol.

Description

technical field [0001] The invention relates to the fields of environmental protection and recycling of resources, in particular to a scrub-resistant shell powder coating that decomposes formaldehyde efficiently. technical background [0002] At present, the coating building materials represented by latex paint are mainly composed of fillers and adhesives. The base materials are mainly chemical products. During construction and use, the paint will release toxic and harmful gases to the human body, such as formaldehyde, TVOC, etc., which seriously endanger human health. [0003] The main component of shells is calcium compounds, including 95% calcium carbonate, and a small amount of trace elements, chitin and amino acids. The shell powder coating prepared with shell powder as the main raw material is green and environmentally friendly. Due to its porous structure and slightly alkaline characteristics, the shell powder coating has the functions of bactericidal and antibacteri...
