Abstract

The invention discloses a fireproof coating and a preparation method thereof. The fireproof coating comprises, by weight, 30-40 parts of a fluorosilicone-modified acrylate emulsion, 20-35 parts of a waterborne polyurethane resin, 0.6-1.5 parts of sodium sulfosuccinate, 0.5-1.0 part of vinyl trimethoxysilane, 10-20 parts of ammonium polyphosphate, 12-17 parts of zinc borate, 5-10 parts of pentaerythritol, 10-20 parts of diatomite, 7-15 parts of expanded perlite, 0.5-1.5 parts of gamma-Al2O3, 5-10 parts of nano-titanium dioxide, 1-2 parts of a film-forming agent, 0.02-0.05 parts of a defoamer and 40-60 parts of water. The fireproof coating has the advantages of short drying time, good adhesion, high mechanical strength, excellent heat resistance, high temperature resistance, water resistanceand salt mist corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a fireproof coating and a preparation method thereof. Background technique [0002] Water-based coatings use water as a solvent or as a dispersion medium, with little environmental pollution and low prices. They can be used on various materials such as metal, plastic, glass, etc., which is the development trend of coatings in the future. However, the existing water-based paint film is soft, not water-resistant, not corrosion-resistant and has poor adhesion, and cannot meet the requirements of industrial production. [0003] The Chinese patent with the notification number CN104059440B discloses a water-based coating with high weather resistance, including the following raw materials in parts by weight: 40-60 parts of a mixture of polyurethane resin and polystyrene-acrylate copolymer emulsion, 15-25 parts of kaolin, 0.5-3 parts of iron pigments, 0.1-0.8 parts of borax...
