Abstract

The invention discloses a method for preparing anti-mildew formaldehyde removal coating. The coating comprises a polystyrene-acrylic acid copolymer or a polyacrylic acid copolymer or a polyvinyl acetate-acrylic acid copolymer, talcum powder, an assistant, pigment, an anti-mildew fungicide, an adsorbent and water. The method comprises the steps of mixing the anti-mildew fungicide with the assistant; mixing the talcum powder with the pigment and the adsorbent; mixing the polystyrene-acrylic acid copolymer or the polyacrylic acid copolymer or the polyvinyl acetate-acrylic acid copolymer with the water, and mixing the foregoing mixtures. The coating prepared by the method disclosed by the invention can effectively resist mildew and has a durable effect, and meanwhile, the coating has a formaldehyde removal function.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a preparation method of an anti-mildew and formaldehyde-removing coating. Background technique [0002] At present, in house decoration, due to the formaldehyde, benzene series, TVOC and other harmful substances brought by various decoration materials, the home decoration pollution and the harmful substances in the indoor air exceed the standard. It has seriously interfered with people's daily life. The long-term absorption of this formaldehyde-containing gas by the human body can cause various diseases, and even endanger human life in serious cases. Therefore, it is necessary to control the indoor air pollution of the renovated rooms and the newly purchased furniture, and eliminate the pollution of harmful gases brought by the new furniture. In order to ensure that the content of indoor harmful gases is within the range stipulated by the state, people can live in a healthy env...
