NOVELTY - Negative oxygen ion releasing inorganic aqueous coating comprises 54 g water, 1 g tourmaline powder, 0.1 g graphene powder, 0.5 g dispersing agent, 0.1 g surfactant, 0.3 g defoamer, 1 g ethylene glycol, 12 g titanium dioxide, 8 g diatomaceous earth, 3.6 g kaolin, 16.4 g pure acrylic emulsion, 1.1 g polyurethane thickener, 0.1 g preservative, 0.4 g anti-fungal agent, 1.2 g film forming aid and 0.2 g fungicide. USE - Negative oxygen ion releasing inorganic aqueous coating. ADVANTAGE - The environmentally-friendly aqueous coating removes aldehyde, purifies wall surface air with selective adsorption, purifies and effectively removes free formaldehyde in air at purification rate of 80.9% and sterilization rate of 91% in 4 hours, removes smell of harmful substances such as benzene, ammonia, and odor generated by smoking, pets and garbage, indoor air, and releases negative oxygen ions in natural environment which calms, hypnotizes and lowers blood pressure, and strengthens oxidation process of kidney, liver and brain of human body. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of negative oxygen ion releasing inorganic aqueous coating which involves spraying, scraping and rolling, adding water and discharging powder, mixing product according to ratio of powder to water of 1:1.2 , maintaining distance of 0.8 from wall when spraying with spray gun at speed of two seconds per meter, spraying twice, and drying every time with theoretical data of 4-5 square meters per kilogram, and spraying effect is matte cloth surface, adding water after discharge, evenly mixing according to powder ratio of 1:0.6, scraping wall three times in sequence, using plastic scraper to sequentially polish with theoretical data of 2-3 square meters per kilogram, and scraping effect is as smooth as fine magnetic, preparing ratio of powder to water according to 1:1.2, pouring water and powder into bucket, stirring with high-speed electric mixer for 5 minutes and in colloid mill theoretical data of 4-5 square meters and carrying out construction and treatment of bright angle and plaster line.
