Abstract

The invention discloses a fireproof coating for steel, and belongs to the field of industrial cleaning agents. The fireproof coating for steel comprises, by weight, 30-50 parts of acrylic resin, 20-30parts of TBA epoxy resin, 10-20 parts of an intumescent flame retardant, 5-10 parts of oxidized paraffin, 3-5 parts of titanium dioxide, 1-3 parts of bentonite, 1-3 parts of dimethicone, 2-5 parts ofammonium molybdate and 100-200 parts of deionized water. The coating has the advantages of large amount of generated carbide, small amount of formed smoke, strong coating adhesion and good acid and alkali resistance.

Description

technical field

[0001] The invention relates to the field of coatings, in particular to a fireproof coating for steel materials. 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 fireproof coating, the amount of fireproof coating used in the project is greatly reduced compared with thick and thin steel structure fireproof coatings, thereby reducing the total cost of the project and enabling effective fire protection...
