NOVELTY - Aqueous coating, comprises 30-50 pts. wt. resin, 2-6 pts. wt. modified diatomite, 1-4 pts. wt. negative ion powder, 0.1-0.3 pts. wt. polysiloxane, 2-4 pts. wt. ethylene glycol mono butyl ether, 0.5-2 pts. wt. hydroxyethyl cellulose and 10- 18 pts. wt. deionized water, where the modified diatomite is prepared by introducing quaternary ammonium salt functional groups on its surface through chemical grafting. The negative ion extraction agent is prepared by modifying many hydroxy groups on the surface of graphene oxide. The resin includes amino resin, epoxy resin and/or acrylic resin USE - Used as aqueous coating containing negative ion powder. ADVANTAGE - The coating: has excellent antibacterial performance; and can realize the treatment method of first adsorption and then inactivation of bacteria. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a production process of the aqueous coating.
