Abstract

The invention belongs to the technical field of fireproof paint and particularly relates to steel structure fireproof paint. The steel structure fireproof paint is mainly composed of, by weight, 40-60% of compound binder resin, 15-20% of fire retardants, 1-3% of cuprous oxide, 0.5-3% of vermiculite, 2-5% of aluminum polyphosphate, 1-3% of zinc oxide, 0.5-1% of a flatting agent, 15-20% of acetone, 1-5% of 1,2-benzisothiazolin-3-one and 1-5% of butyl p-hydroxybenzoate. The steel structure fireproof paint has prominent fireproof performance and good anticorrosion and mildew-resistant performance as well.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings, and in particular relates to a fireproof coating for steel structures. Background technique [0002] Steel structure has the advantages of light weight, easy installation, short construction period, excellent seismic performance, high degree of mechanization in manufacturing and installation, and less pollution. a fatal flaw. Steel structures usually lose their bearing capacity at a temperature of 450-650°C, undergoing large deformations, causing steel columns and steel beams to bend, and as a result, cannot continue to be used due to excessive deformation. Generally, the fire resistance of steel structures without protection The limit is around 15 minutes. The length of this time is also related to the speed at which the component absorbs heat. [0003] Spraying fire-resistant coatings on the outside of steel structures to form outsourcing is a common method to achieve fire prevent...
