The flame retardant coating includes the following components by weight: 15 parts of calcium carbonate, 12 parts of hydroxyethyl cellulose, 7 parts of sodium hexametaphosphate, 6 parts of anhydrous sodium sulfite, 7 parts of dehydrated sodium silicate, 12 parts of crystalline silicon 10 parts of magnesium dioxide, 12 parts of quicklime, 6 parts of quasi-spherical silica powder, 13 parts of carbon black, 4 parts of plant fragrance, 4 parts of natural antibacterial agent, 3 parts of vinyl acetate, 10 parts of sodium sulfate, 5 parts of zinc oxide 10 parts, 10 parts of zinc dihydrogen phosphate, 5 parts of additives, 12 parts of aluminum hydroxide flame retardant. The preparation method is simple, has good self-drying property, strong adhesion, convenient construction, good fire resistance and fire prevention performance, and many raw materials in it are environmentally friendly raw materials, which are relatively safe and environmentally friendly, and the raw materials are easy to obtain, and the production cost is low. It also includes natural fragrances, so that the coated furniture has a natural fragrance.

Description

technical field [0001] The invention relates to a novel flame-retardant 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. At present, almost all the surfaces of furniture boards are coated with coatings. These coatings can form thin films under certain conditions to protect, decorate or other liquid or solid materials with special functions, such as Insulation, anti-rust, anti-mildew, heat resistance, etc. However, there are still som...

Problems solved by technology

However, there are still some deficiencies in the existing flame-retardant coatings. In the existing technology of realizing flame-retardant substrates through the catalytic charring of the coating film, the dehydration catalyst used has a high decomposition temperature and poor low-temperature activity. poor performance

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
