Abstract

The invention discloses a high-temperature-resistant steel structure coating which is prepared from the following raw materials in parts by weight: 20-40 parts of aqueous resin, 50-60 parts of a silicon dioxide-aluminum oxide mixture, 4-10 parts of nano zinc oxide, 15-20 parts of zinc powder, 1-5 parts of expansible graphite, 3-5 parts of aluminum polyphosphate, 0.5-1 part of ammonium polyphosphate, 5-10 parts of tricresyl phosphate, 4-8 parts of aluminate borate and 3-6 parts of ammonium carbonate. The high-temperature-resistant steel structure coating can tolerate long-time high-temperatureroasting to play fireproof and heat-isolating roles. The coating is not flaked or cracked when a fire happens, and does not release toxic and harmful gas, so that the coating is highly safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to a high-temperature-resistant steel structure coating. Background technique [0002] As a form of high-rise building structure, steel structure is widely used in the construction industry due to its high strength, light weight, good extensibility, earthquake resistance and short construction period, but because the steel structure itself is not combustible, The problem of fire and heat insulation protection of steel structures was once neglected by people. According to relevant domestic and foreign reports and the tests and statistics of relevant institutions, the fire resistance of steel structure buildings is worse than that of masonry structures and reinforced concrete structures. The mechanical strength of steel decreases with the increase of temperature. At about 5000 °C, its strength drops to 40% to 50%, and the mechanical properties of steel, such as yield point, compressiv...
