Abstract

The invention discloses an aqueous ultrathin expansion-type fireproof coating for a steel structure and a preparation method thereof, and belongs to the technical field of fireproof coatings. The aqueous ultrathin expansion-type fireproof coating comprises, by mass, 10-35 parts of a modified aqueous epoxy emulsion, 1-8 parts of a curing agent, 5-15 parts of a styrene-acrylic emulsion or a silicone-acrylic emulsion, 10-20 parts of ammonium polyphosphate, 6-12 parts of melamine, 8-16 parts of pentaerythritol, 5-15 parts of a fire retardant, 5-15 parts of a pigment and a filling material, 2-8 parts of an assistant and 15-35 parts of water. The aqueous ultrathin expansion-type fireproof coating has the characteristics of low raw material cost, simple preparation process and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings, in particular to a water-based ultra-thin intumescent fireproof coating for steel structures and a preparation method thereof. Background technique [0002] As a type of building, steel structure is widely used for its advantages of light weight, high strength, good plasticity, and short construction period, especially in long-span structures and high-rise buildings. However, steel structures have poor fire resistance. When the temperature reaches 600°C, the steel structure will lose almost all its strength. Once a fire occurs, the steel structure will lose its bearing capacity, which will seriously endanger people's lives and property safety. Therefore, it is necessary to protect the steel structure from fire. The method widely used at present is to coat the surface of the steel structure with a steel structure fireproof coating.
