ORGANIC-INORGANIC HYBRID FIREPROOF COATING AND PREPARATION METHOD THEREFOR

WIPO Patent Application WO/2021/175065

A1

The embodiments of the present application provide an organic-inorganic hybrid fireproof coating and a preparation method therefor, and relate to the field of fireproof coatings. The raw materials of the fireproof coating include, by mass percentages, 15-22% of potassium water glass, 5-10% of a vinyl acetate-ethylene copolymer emulsion, 0.2-0.6% of cellulose, 0.2-0.5% of an aqueous dispersant, 0.1-0.3% of an aqueous wetting agent, 0.3-0.5% of an aqueous defoamer, 2.2-4.1% of a film forming auxiliary, 13-28% of a filler auxiliary, 20-30% of a flame retardant, and 22-23.6% of water. The preparation method involves adding a dispersant, a wetting agent, a defoamer, a film forming auxiliary and water to a cellulose solution, and stirring same; then adding a rutile-type titanium dioxide powder, a filler auxiliary and a flame retardant, and stirring same; adding a vinyl acetate-ethylene copolymer emulsion, and stirring same; and adding potassium water glass, and stirring same. The fireproof coating has the characteristics of a high-temperature resistance, a good water resistance, a high fireproof rating, a fast drying speed, etc.
