High weathering flame-retardant decorative coating and preparation method thereof

Abstract

The invention provides a high weathering flame-retardant decorative coating and a preparation method thereof. The coating is prepared from the following raw materials in parts by weight: 20-40 parts of hydroxy acrylic resin, 12-20 parts of carboxyl-type vinyl chloride-vinyl acetate resin, 15-30 parts of bisphenol A type epoxy resin, 10-30 parts of glycine, 5-10 parts of isopropylamine sodium dodecyl benzene sulfonate, 7-12 parts of magnesium hydroxide, 4-10 parts of antimony trioxide, 6-13 parts of a nano-enhancer, 3-8 parts of gamma-aminopropyltriethoxysilane, 8-15 parts of tetrabromobisphenol S bis(2,3-dibromopropyl)ether, 2-5 parts of polyoxyethylene polyoxypropylene ether block copolymer, 1-4 parts of polydimethylsiloxane, 3-6 parts of n-butyl stearate, 2-7 parts of microcrystalline paraffin, 10-20 parts of isopropanol, and 20-50 parts of water. The coating prepared by the invention has the dual properties of flame retardation and high weather resistance, so the coating has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of decorative materials, and in particular relates to a highly weather-resistant and flame-retardant decorative paint and a preparation method thereof. Background technique [0002] Flame-retardant coatings, also known as fire-resistant coatings, are special functional coatings. In addition to the same decoration, anti-corrosion and prolonging the service life of the protected materials as ordinary decorative coatings, when the substrate encounters flames or heat radiation, the flame-retardant Coatings can rapidly undergo physical and chemical changes, thereby insulating heat, preventing flames from spreading, and playing a flame-retardant role. In recent years, the application and development of flame-retardant coatings has been highly valued in my country. At present, most of the domestic use of emulsions as film-forming materials, and amino resins are also used as base materials for flame-retardant coatin...

Problems solved by technology

In recent years, the application and development of flame-retardant coatings has been highly valued in my country. At present, most of the domestic use of emulsions as film-forming materials, and amino resins are also used as base materials for flame-retardant coatings. Foaming agent and other additives, but the acid and alkali resistance, water resistance and aging resistance of the coating are often difficult to meet the needs at the same time, making the weather resistance of the coating poor

At the same time, the preparation cost of the existing flame-retardant high-weather-resistant coatings is high, the toxicity is high, and it is not conducive to popularization and application
