Problems solved by technology

At present, the formaldehyde removal coatings on the market mainly add activated carbon components, which have poor formaldehyde adsorption persistence and are easy to reach adsorption saturation, and the escape of formaldehyde after adsorption saturation will cause secondary pollution; existing antibacterial coatings are added with organic amines. Azines and isothiazolinones are used as antibacterial agents, and their short-term antibacterial effect is obvious, but their durability is poor, their temperature resistance is poor, and harmful substances will be produced after decomposition under ultraviolet light
In addition, the volatilization process of volatile organic compounds added in liquid paint will also pollute the indoor air.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a formaldehyde-removing antibacterial and environmentally friendly powder coating for indoor use. Background technique [0002] In recent years, people have paid more and more attention to the safety of interior decoration, especially the use of environmentally friendly functional coatings has been sought after by people. At present, the formaldehyde-removing coatings on the market mainly add activated carbon components, which have poor formaldehyde adsorption persistence and are easy to reach adsorption saturation, and the escape of formaldehyde after adsorption saturation will cause secondary pollution; Azines and isothiazolinones are used as antibacterial agents, and their short-term antibacterial effect is obvious, but their durability is poor, their temperature resistance is poor, and harmful substances will be produced after decomposition under ultraviolet rays. In addition, the vo...
