Flame-retardant anti-corrosion acrylic coating

Abstract

The invention discloses a flame-retardant anti-corrosion acrylic coating. The flame-retardant anti-corrosion acrylic coating is prepared from the following raw materials in parts by weight: 60-70 parts of water-soluble acrylic resin, 12-15 parts of water-soluble phenolic resin, 8-11 parts of butadiene styrene resin, 3-4 parts of laurate dihydroxyethylamide, 2.8-3.1 parts of hydroxypropyl methyl cellulose, 15-18 parts of sepiolite, 5-8 parts of talc powder, 1-2 parts of montmorillonite powder, 2-3 parts of melamine phosphate, 14-17 parts of magnesium hydroxide nanoparticles, 3-4 parts of tricresyl phosphate, 10-15 parts of methylated amino resin, 2-3 parts of manganese abietate, 0.4-0.6 part of an epoxy-silane coupling agent, 15-25 parts of a pigment, 2.1-2.4 parts of a flexibilizer, 0.5-0.8 part of a defoamer, 0.7-1 part of a smoothing agent, 0.4-0.5 part of a mildew preventive, and 50-55 parts of a solvent. The flame-retardant anti-corrosion acrylic coating disclosed by the invention is excellent in flame-retardant and heat-resisting properties, and good in anti-corrosion property.

Description

technical field [0001] The invention relates to the technical field of flame-retardant coatings, in particular to a flame-retardant and corrosion-resistant acrylic coating. 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, ...

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
