MULTIFUNCTIONAL COMPOSITE COATING FOR REMOVING FORMALDEHYDE AND UNDESIRABLE ODORS AND PREVENTING BACTERIA AND MILDEW, AND PREPARATION METHOD THEREFOR

摘要

A multifunctional composite coating for removing formaldehyde and undesirable odors and preventing bacteria and mildew comprises functional micro-nano powders, a resin adhesive and additives. The powders comprise nano-scale Anatase titanium dioxide, micrometer-scale porous diatomite, micrometer-scale adsorption carbon and micrometer-scale calcium carbonate. The additives comprise a surfactant and a dispersant. In the preparation, the powders are added into the resin adhesive, and then the additives are added and stirred. The coating can remove formaldehyde and undesirable odors and prevent bacteria and mildew on a day and a night that has no light.
