USE - Aqueous coating for building materials (claimed). ADVANTAGE - The aqueous coating has excellent elasticity, toughness, wear resistance, high and low temperature performance, water resistance, UV resistance, dielectric resistance, and radiation resistance, and does not cause pollution when burned. DETAILED DESCRIPTION - An aqueous coating comprises 60-70 pts. wt. trifluorofluorooctyltrimethoxysilane, 12-17 pts. wt. aluminum oxide modified graphene oxide flame retardant, 12-17 pts. wt. emulsifier, 22-27 pts. wt. hydrotalcite, 2-7 pts. wt. coupling agent, 2-7 pts. wt. dispersant, 0.1-3 pts. wt. reinforcing agent, 0.5-3 pts. wt. inorganic pigment, and 170-200 pts. wt. deionized water. The emulsifier is one or more of polyvinyl benzenesulfonic acid, sodium polyvinyl benzenesulfonate, sodium dodecyl sulfate, sodium dodecylsulfonate, sodium dodecylbenzenesulfonate, cetyltrimethylammonium bromide, and sodium dioctyl peroxysulfonate. The inorganic pigment is one or more of titanium white, chrome yellow, iron blue, cadmium red, cadmium yellow, lithopone, carbon black, iron oxide red, and iron oxide yellow. The coupling agent is a silane coupling agent which is one of KH550 (RTM: 3-aminopropyltriethoxysilane), KH560 (RTM: 3-glycidoxypropyltrimethoxysilane), KH570 (RTM: 3-methacryloxypropyltrimethoxysilane), KH792 (RTM: (3-(2-aminoethyl)aminopropyl)trimethoxysilane), DL602 (N-( beta -aminoethyl)- gamma -aminopropylmethyldiethoxysilane), and DL171 (N-( beta -aminoethyl)- gamma -aminopropylmethyl-dimethoxysilane). The dispersant is one or more of liquid paraffin, microcrystalline paraffin, barium stearate, zinc stearate, calcium stearate, cadmium stearate, magnesium stearate, copper stearate, polyethylene glycol 200 and polyethylene glycol 400. The reinforcing agent is one or more of silicon carbide fiber, nano titanium carbide, ceramic powder, 3-chloro-2-hydroxypropyltrimethylammonium chloride, polyacrylamide, polyvinylamine, carboxymethyl cellulose polyvinyl alcohol, sodium polyacrylate, sodium caseinate, hydroxyapatite and sodium carboxymethyl cellulose. An INDEPENDENT CLAIM is included for preparation of aqueous coating, which involves adding trifluorofluorooctyltrimethoxysilane to the reaction kettle, stirring well, adding half amount of deionized water and emulsifier, ultrasonically processing at power of 400-600 W for 30 minutes, stirring at room temperature for 4-6 hours to obtain emulsion (A), heating aluminum oxide modified graphene oxide flame retardant, hydrotalcite, coupling agent, dispersant, reinforcing agent and remaining deionized water in water bath at 30-50 degrees C, stirring for 3-4 hours, cooling, discharging, adding inorganic pigments, mixing evenly to obtain component (B), and mixing emulsion (A) and component (B) with electronic stirrer.
