Abstract

The invention provides a fireproof coating composition. The coating composition comprises colored sand and a binder which are respectively and independently preserved. The invention also provides a fireproof steel material. The fireproof steel material comprises a steel material main body, a fireproof base layer coated on the steel material main body, and a fireproof surface layer coated on the fireproof base layer, wherein the fireproof surface layer is formed by curing the binder in the fireproof coating composition provided in the invention. The fireproof steel material prepared according to the invention has the advantages of fine surface, and good fire proofness, water proofness and weatherability.

Description

technical field [0001] The invention relates to a fireproof coating composition and a fireproof steel material comprising a fireproof surface layer formed by the fireproof coating composition. Background technique [0002] Existing fireproof coatings for steel structures are divided into thin-coated fireproof coatings for steel structures and thick-coated fireproof coatings for steel structures. The thin-coated steel structure fireproof coating is an intumescent fireproof coating, which has good fireproof and heat insulation performance, light coating quality, and certain aesthetic and decorative effects, but it is expensive and not suitable for large-scale promotion and use. Thick-coated fire retardant coatings for steel structures are non-expanding fire retardant coatings and are mainly composed of binders, aggregates and additives. The binders are selected from Portland cement, magnesium hydroxide, potassium silicate, aluminum ceramic powder At least one of materials, at...
