USE - Halogen-free flame retardant silane water-based paint used in the field of building materials (claimed). ADVANTAGE - The halogen-free flame retardant silane water-based paint does not produce secondary pollution during combustion, has good elasticity and a tough, wear-resistant surface, and has excellent high and low temperature performance, waterproof and ultraviolet resistance. The coating has a suitable viscosity, easy to use spraying, dipping, brushing or pouring coating and other operating methods, is a widely used and very ideal protective material. DETAILED DESCRIPTION - Halogen-free flame retardant silane water-based paint comprises 65 pts. wt. tridecafluorooctyltrimethoxysilane, 15 pts. wt. flame retardant graphene oxide modified by aluminum oxide, 16 pts. wt. emulsifier, 25 pts. wt. hydrotalcite, 5 pts. wt. coupling agent, 5 pts. wt. dispersant, 1 pts. wt. reinforcing agent, 2 pts. wt. inorganic pigment, and 185 pts. wt. deionized water. The emulsifier is selected from polyvinylbenzenesulfonic acid, sodium polyvinylbenzenesulfonate, sodium dodecyl sulfate, sodium dodecylsulfonate, sodium dodecylbenzenesulfonate, cetyl trisulfonate or one or more of methyl bromide and sodium dioctyl sulfonate. The inorganic pigment is selected from 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, selected from one of KH550, KH560, KH570, KH792, DL602, DL171. The dispersant is selected from liquid paraffin, microcrystalline paraffin, barium stearate, zinc stearate, calcium stearate, cadmium stearate, magnesium stearate, copper stearate, polyethylene glycol 200 and poly ethylene glycol 400. The reinforcing agent is selected from 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 a method for preparing a halogen-free flame-retardant silane water-based paint, which comprises (A) adding tridecylfluorooctyl trimethyl to the reaction kettle Oxysilane, stirring, adding 1/2 deionized water and emulsifier, sonicating for 30min, then stirring at room temperature for 4-6h to obtain emulsion A; (B) adding the graphite oxide modified by aluminum oxide, hydrotalcite, coupling agent, dispersant, reinforcing agent and the remaining 1/2 deionized water, heating at 30-50 degrees C water bath, stirring for 3-4h, cooling down, discharging, adding inorganic pigments, and mixing well to get component B; and (C) mixing emulsion A and component B with an electronic stirrer to obtain a halogen-free flame retardant silane water-based paint.
