NOVELTY - Wood-structured flame-retardant coating comprises 100 pts. wt. aqueous film-forming substrate, 200-250 pts. wt. intumescent flame retardant, 20-30 pts. wt. titanium dioxide, 0.01-5 pts. wt. graphene substances, 1-2 pts. wt. additives, 200-250 pts. wt. water and 50-80 pts. wt. flame retardant powder additives comprising methoxy acrylic resin, P-N composite flame retardant, inorganic filler, aluminum hydroxide and antimony halide. USE - Wood-structured flame-retardant coating. ADVANTAGE - The coating improves the strength of the carbonized layer, and has excellent phosphorus-nitrogen synergistic effect, excellent flame retardant effect, and excellent thermal insulation due to loose texture, and expands in heat to form uniform and dense carbon foam layer, isolates oxygen, delays the rate of heat transfer to the protected substrate, and plays effective role in heat protection and heat insulation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the coating, involving (a) weighing the above-mentioned material, evenly mixing water, additives, and titanium dioxide, adding aqueous film-forming substrate, intumescent flame retardant and graphene substances, and evenly stirring to obtain an aqueous phase, (b) mixing the methoxy acrylic resin, P-N composite flame retardant, inorganic filler, aluminum hydroxide and antimony halide to obtain the flame retardant powder additives, and (c) mixing the aqueous phase and flame retardant powder additives, grinding, and sieving the material.
