Abstract

The invention provides a fireproof paint for a steel structure. The fireproof paint comprises, by mass, 20 to 40 parts of dodecanol ester, 50 to 60 parts of silica-alumina mixture, 5 to 10 parts of titanium dioxide, 0.5 to 1 part of ammonium polyphosphate and 5 to 10 parts of tritolyl phosphate. The fireproof paint for the steel structure can withstand high-temperature baking for a long time, exerts fireproof and heat-insulation effect, prevent steel from strength reduction due to rapid heating in a fire hazard and avoids collapse of a building caused by the situation that the steel structure loses supporting capability.

Description

technical field [0001] The invention belongs to the technical field of fireproof coatings, in particular to a fireproof coating for steel structures. 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...
