Problems solved by technology

However, because the steel structure itself is not combustible, the fire protection and heat insulation protection of the steel structure was once ignored. According to relevant information reports and test data statistics, the fire resistance of steel structure buildings is worse than that of masonry structures and reinforced concrete structures.
Steel structure fire retardant coatings are divided into thick, thin and ultra-thin steel structure fire retardant coatings according to thickness. However, the existing thick steel structure fire retardant coatings are easy to crack due to insufficient coating strength during use, which affects the fire retardant coating. Excellent fire and heat insulation performance

Description

Technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to a nano-graphene fireproof coating and a construction method thereof. Background technique [0002] As a form of building structure, steel structure is widely used in the construction industry because of its high strength, light weight, good extensibility, seismic resistance and short construction period. However, because the steel structure itself is incombustible, the fire and heat insulation protection of the steel structure was once ignored. According to relevant data reports and test data statistics, the fire resistance of steel structure buildings is worse than that of masonry and reinforced concrete structures. The mechanical strength of steel decreases with the increase of temperature. At about 500°C, its strength greatly decreases. The mechanical properties such as yield point, compressive strength, elastic modulus, and load capacity are all rapidly decreased, and t...
