The mainstream fireproof coating in the market at present is a thick fireproof coating, the fire resistance limit of the thick fireproof coating can reach 3 hours, but the coating has poor decoration, high density and poor coating adhesion, and the coating thickness causes certain burden on a steel structure. The coating is thin and ultrathin, has good coating effect and good adhesive force, but has poor weather resistance, the fire resistance limit is only 1-2h, and the use is limited to a certain extent. Therefore, the development of the ultra-thin fireproof coating with long fire resistance limit has good application value.
