Abstract

The invention discloses an anti-mildew formaldehyde-removing coating. The coating contains the following components in part by weight: 100 parts of polystyrene-acrylic copolymer or polyacrylic acid copolymer or polyvinyl acetate-acrylic copolymer, 26-30 parts of talcum powder, 5-8 parts of additive, 6-10 parts of pigment, 8-10 parts of anti-mildew bactericide, 3-5 parts of adsorbent and 40-50 parts of water, wherein the anti-mildew bactericide is the mixture of nanometer TiO2, nanometer ZnO and ZrO2, the granularity of nanometer TiO2 and nanometer ZnO is 30-50 nanometers, the granularity of ZrO2 is minus 400 meshes, and the ratio of nanometer TiO2, nanometer ZnO to ZrO2 is (1-2):1:0.5. The anti-mildew formaldehyde-removing coating is capable of effectively resisting mildewing and long in effect, and the coating also has a formaldehyde-removing function.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to 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 environment. [0003] In r...
