Abstract

The invention discloses an ultraviolet-resistant corrosion-resistant thin coating type water-based fireproof coating material, which comprises a water film, a flaky substance and an auxiliary agent, wherein the water film is prepared from the following substances in parts by weight: 30 to 60 parts of deionized water, 25 to 40 parts of a waterborne epoxy resin, 20 to 40 parts of chlorinated rubber emulsion, 10 to 20 parts of polytetrafluoroethylene emulsion, 5 to 15 parts of polyacrylic acid, 3 to 5 parts of polyethylene and 2 to 4 parts of chlorosulfonated polyethylene, the scaly substance is selected from one of flake graphite, glass flakes, flake mica or basalt flakes, the auxiliary agent comprises one or more of an ultraviolet light absorber, a light stabilizer, wear-resistant micro powder, a defoaming agent and a leveling agent, the mass percentage of the water film is 82-93%, the mass percentage of the scaly substance is 5-10%, and the mass percentage of the assistant is 2-8%. According to the invention, large-area basalt scales are used as an additive component of a thin-coating type water-based fireproof coating material, so that the salt spray resistance of the coating material can be improved on the premise of ensuring the adhesive force of the coating material, and the coating material has multiple properties.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an ultraviolet-resistant and corrosion-resistant thin-coated water-based fireproof coating and a preparation method thereof. Background technique [0002] The fire retardant coating is applied to the surface of the material to make the material have fire resistance, which can slow down the spread of flame or prevent burning for a certain period of time. Building fire prevention is an important application field of fireproof coatings, mainly fireproof coatings for steel structures. In order to achieve the purpose of fireproofing steel structures, fireproof coatings are mostly thick-coated coatings. Since this type of coating has sufficient thickness (8-45mm), so A certain amount of functional materials can be added to the coating to make the coating have composite functions, such as adding zinc powder or scaly substances to make the coating have the function of anti-corrosion and salt spra...
