Abstract

The invention relates to an expansion-type fireproof coating. The coating comprises, by weight, 10-40 parts of resins, 0-40 parts of catalysts, 5-20 parts of charring agents, 5-20 parts of foaming agents, 3-15 parts of fire retardants and 3-15 parts of carbon nanotubes. The expansion-type fireproof coating has good fire proofing and heat insulating properties, good bonding force and high intensity, and can endure high low temperature cycling. The coating has advantages of good water resistance, good acid resistance, good salt corrosion resistance, stable storage, good decoration and convenient construction, and is not easy to fall off. The coating solves the problems of low expansion rate of fireproof coatings and low compactness of charring layers in the prior art, and has excellent fireproof performance.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to an intumescent fireproof coating, which can be used as fireproof coatings for steel structures, decorative surface fireproof coatings and cable fireproof coatings. Background technique [0002] In terms of fire prevention mechanism, fire retardant coatings are generally divided into two types: intumescent and non-intumescent. Non-intumescent fire retardant coatings rely on their own high flame retardancy or non-combustibility to achieve the purpose of flame retardant and fire prevention. To achieve a good fire prevention effect, it must be coated very thickly, and a large amount of halogen, nitrogen, phosphorus and other flame retardants are added to produce Lots of toxic gas. Intumescent fireproof coating means that the coating film expands when heated to form a honeycomb carbonized layer, which isolates the heat of the flame and reduces or slows down the transfer to...
