Fireproof paint

Abstract

The invention discloses a fireproof paint. The fireproof paint comprises following ingredients, by mass, 2 to 4 parts of triglycidyl isocyanurate, 2 to 5 parts of aluminum oxide, 5 to 10 parts of zirconium oxide, 1 to 4 parts of zinc oxide, 2 to 6 parts of magnesium hydroxide, 15 to 25 parts of epoxy acrylic acid resin, 25 to 40 parts of vinyl acetate resin, 45 to 60 parts of hydroxy polyester resin, 5 to 10 parts of hydroxy acrylic resin, 20 to 30 parts of amino resin, 10 to 15 parts of melamine, 1 to 5 parts of meerschaum powder, 10 to 15 parts of silica sol, 1 to 3 parts of nano TiO2 and / or nano ZnO, and 20 to 25 parts of water. The raw materials of the fireproof paint are easily available, and are cheap; a preparation method of the fireproof paint is simple; paint coating possesses excellent flame resistance; nano TiO2, nano ZnO, and nano SiO2 are added, and long-lasting antibacterial performance is obtained because of adding of the inorganic materials; and the fireproof paint is nontoxic, is friendly to the environment, and is suitable for industrialization.

Description

technical field [0001] The invention relates to a fireproof coating, which belongs to the technical field of coatings. Background technique [0002] At present, the amount of wood materials and paints used in interior decoration is increasing year by year. Due to the flammability and flammability of wood materials and some paints, there must be fire hazards. In recent years, due to the extensive use of decorative materials, such fires are on the rise. The preparation of new non-combustible and flame-retardant decorative materials has been highly valued by relevant state departments. Therefore, flame-retardant coatings have become a research hotspot, but there are still some deficiencies in existing flame-retardant coatings. The existing technology of realizing flame-retardant substrates through the catalytic charring of coating films uses a dehydration catalyst with a relatively high decomposition temperature. However, the low-temperature activity is poor, and the flame re...

Problems solved by technology

Therefore, flame-retardant coatings have become a research hotspot, but there are still some deficiencies in existing flame-retardant coatings. The existing technology of realizing flame-retardant substrates through the catalytic charring of coating films uses a dehydration catalyst with a high decomposition temperature. However, the low temperature activity is poor, and the flame retardant performance of the coating is not good.

Because when a fire occurs, the film-forming substance is often thermally decomposed before the dehydration catalyst, producing more flammable volatile organic compounds, affecting the formation and structure of the carbon layer, and thus affecting the protection of the substrate
