Abstract

The invention discloses high weather resistance outdoor ultra-thin steel structure fireproof coating. The high weather resistance outdoor ultra-thin steel structure fireproof coating is formed by the following components of, by weight, 60 parts of acrylic emulsion, 33 parts of organic silicon modified styrene acrylic emulsion, 18 parts of melamine, 9 parts of pentaerythritol, 4 parts of ethylene glycol, 24 parts of calcium carbonate, 16 parts of ammonium polyphosphate, 6 parts of titanium dioxide, 15 parts of flame retardant, 0.2 part of silicone oil, 2 parts of chlorinated paraffin and 26 parts of water. The selected acrylic emulsion is good in adhesion, low in expansion speed, long in duration, high in expanded multiplication rate, more in carbide, uniform in bubble hole, compact in expansion layer and high in hardness and accordingly the fireproof effect is good and the acrylic emulsion can serve as a film forming substance of the ultra-thin steel structure fireproof coating. The weather resistance of the coating is significantly improved, the transparency is high, the chemical property is stable, the mechanical strength is high, the heat resistance is good, and the like due to the formula of the high weather resistance outdoor ultra-thin steel structure fireproof coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an outdoor ultra-thin fireproof coating for steel structures with high weather resistance. Background technique [0002] Ultra-thin fireproof coatings for steel structures refer to fireproof coatings for steel structures with a thickness of no more than 3mm. This kind of fireproof coating expands and foams when exposed to fire to form a dense fireproof and heat insulation layer. It is a core variety developed in recent years. This kind of coating is especially suitable for the fire protection and decoration requirements of light steel roof trusses and ball joint steel grids of buildings such as airports, convention centers, cultural and sports venues, etc. Due to the ultra-thin coating of this type of fire retardant coating, the amount of fire retardant coating used in the project is greatly reduced compared with thicker and thinner steel structures, thereby reducing the total c...
