Problems solved by technology

[0003] Although water-based coatings can reduce the pollution to the atmosphere, there are still organic substances in the water-based coatings. These organic substances exist in the coatings as fillers and substrates, and their content is about 2-12%, which will still pollute the environment. Therefore, it is necessary to provide a Coatings that remove organic matter and purify the air

Abstract

Environmental-friendly coating adsorbing formaldehyde is disclosed. The coating comprises following raw materials by weight: 80-90 parts of ethyl acrylate emulsion, 10-18 parts of water, 2-4 parts of tri(propylene glycol) butyl ether, 20-30 parts of a composite filler, 0.2-0.4 part of Wet500, 2-4 parts of tris(2-ethylhexyl) phosphate, 0.1-0.2 part of methyl cellulose, 0.2-0.4 part of polyacrylamide, 0.1-0.3 part of sodium dodecylbenzenesulfonate, 0.2-0.4 part of polydimethylsiloxane, 0.3-0.5 part of silicone oil emulsion, 0.1-0.3 part of glycol, 0.02-0.04 part of an antiseptic DL702, 0.05-0.07 part of 2-octyl-4-isothiazolin-3-one and 0.2-0.4 part of a levelling agent. Raw materials of the composite filler comprise modified meerschaum, alumina silicate, heavy calcium carbonate and kaolin. The formaldehyde adsorption property of the coating is good.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly coating for absorbing formaldehyde. Background technique [0002] Coating is a new type of polymer material, which has the characteristics of uniformly adhering to the surface of the substrate material to form a firm and crack-free film. Traditional coatings use organic substances as solvents, which will release volatile organic substances during processing and production, which will pollute the environment. Water-based coatings use water as a solvent, which can save a lot of resources, eliminate the risk of fire during construction, and reduce air pollution. [0003] Although water-based coatings can reduce the pollution to the atmosphere, there are still organic substances in the water-based coatings. These organic substances exist in the coatings as fillers and substrates, and their content is about 2-12%, which will still pollute the environment....
