Abstract

The invention relates to an ultra-thin section steel structure weather-resistant fireproof paint, and a preparation method thereof. The ultra-thin section steel structure weather-resistant fireproof paint is composed of, by weight, 20 to 35 parts of modified acrylic resin, 10 to 18 parts of a nonsaturated polyester, 5 to 15 parts of alkyd resin, 10 to 20 parts of melamine phosphate, 4 to 10 partsof hydrated zinc borate, 5 to 10 parts of nanometer calcium carbonate, 3 to 7 parts of vermiculite, 25 to 40 parts of a solvent, 1 to 10 parts of modified barium metaborate, 1.5 to 3.6 parts of bentonite, 1 to 3 parts of a plasticizer, 0.5 to 3 parts of a levelling agent, and 1 to 5 parts of an ultraviolet ray absorber. The preparation process is simple; energy consumption is low; production costis low; the ultra-thin section steel structure weather-resistant fireproof paint possesses excellent flame resistance, weather resistance, bonding performance, sealing performance, is friendly to theenvironment, is wide in application range, and shedding is not easily caused.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an ultra-thin steel structure weather-resistant fireproof coating and a preparation method thereof. Background technique [0002] Ultra-thin fireproof coatings for steel structures refer to fireproof coatings with a coating thickness of no more than 3mm. This kind of coating will expand and foam to form a dense fireproof and heat insulation layer when it encounters a fire. It is usually used on steel structures with a fire resistance limit of 2 hours. This kind of fire retardant coating not only has the decorative and symbolic features of ordinary coatings, but also has the function of fire retardant and flame retardant, which can retard or delay fire when a fire occurs. Therefore, fire retardant coatings are widely used in the petrochemical industry. [0003] Most of the steel structures in the petrochemical industry are in the open air environment. The influence of the natura...
