Abstract

The invention discloses a method for coating anti-mildew formaldehyde removal coating. The coating is composed of 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, wherein the anti-mildew fungicide is a mixture of nano TiO2, nano ZnO and ZrO2, the particle size of each of the nano TiO2 and the nano ZnO is 30-50 nanometers, the particle size of the ZrO2 is 400 meshes, and the proportion of TiO2 to ZnO to ZrO2 is (1-2): 1:0.5. According to the method disclosed by the invention, the brushing method is adopted to a bottom layer and a transitional layer to ensure the smearing property and effect of the coating, the last surface layer coating is sprayed to ensure the surface layer is smooth and beautiful, the coating used by the brushing method does not crack and peel off, the method is simple and easy to implement, and the coating effect is beautiful and practical.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for painting an anti-mildew and formaldehyde-removing paint. 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 environ...
