Abstract

The invention relates to a preparation method of a flame-retardant waterproof coating. According to the preparation method, the problems that existing waterproof coatings are not environmentally friendly, cause environmental pollution and are high in costs can be effectively solved. The preparation method comprises the following steps: dissolving every 3g-7g of hexadecyl trimethyl ammonium bromide into 150ml of distilled water, stirring until dissolving, adding 5g-15g of calcium-based montmorillonite, stirring at the room temperature for 6h-18h, carrying out suction filtration to obtain a filter cake, repeatedly washing the filter cake with distilled water until no sediment is detected by using 0.1mol / L AgNO3 solution, drying, and sieving by virtue of a 200-mesh sieve, so as to obtain modified montmorillonite; diluting every 6g of fluorosilicon resin to 30g with water, adding 0.2g-0.4g of surfactant Triton and 2g-5g of modified montmorillonite, and stirring at the room temperature for 1h-2h; adding 0.7g-1.2g of ammonium polyphosphate, 0.1g-0.5g of melamine and 0.1g-0.3g of zinc borate, stirring at 40-60 DEG C for 1h-3h, adding 0.3g-0.5g of a drier, and further stirring for 20-30 minutes, so as to obtain the flame-retardant waterproof coating. The flame-retardant waterproof coating is environmentally friendly, good in flame retardance, waterproof effect and film coating tenacity and low in cost and has very high practical application value.

Description

technical field [0001] The invention relates to coatings, in particular to a method for preparing flame-retardant waterproof coatings. Background technique [0002] Waterproof coatings are widely used in industrial production and daily life. However, general waterproof coatings are emulsions of polymer oligomers, which are flammable. Therefore, fire-retardant modified waterproof coatings have appeared on the market. For example, when flame retardant modification of polyurethane waterproof coating is carried out, flame retardant and waterproof monomers are reacted, and smoke suppressant is added at the same time to reduce the amount of smoke. The flame retardancy is high, but the process is more complicated. Some people use flame retardant polyols to react with diisocyanates and hydrophilic chain extenders to prepare polyurethane waterproof and flame retardant coatings. Its flame retardant group cannot be smoothly linked to the polyurethane molecular chain due to the hydr...
