The steel structure must be brushed with anticorrosive paint, and the steel structure fireproof paint is a necessary steel structure material which is enforced by the state.
With the improvement of the steel structure anticorrosion requirement and the limitation of environmental protection, the steel structure anticorrosion paint is further developed towards the direction of low solvent and high solid content, so that the paint becomes high-viscosity thick paste type and is more and more difficult to spray. The traditional construction method comprises manual brushing and air spraying, wherein the manual brushing is not only low in efficiency, but also inevitably leaves brush marks, and the paint surface effect is difficult to satisfy; air spraying can not atomize high-viscosity anticorrosive coatings, a large amount of diluent is inevitably added, so that the cost is increased and the environment is polluted, and excessive dilution causes the film forming capability of the paint to be reduced, so that the service life of a paint coating is influenced.
The steel structure fireproof paint is applied to the steel structure surface of buildings and structures, and can form a fireproof heat-insulating protective layer to improve the fire resistance limit of the steel structure. According to GB14907-2002 steel structure fireproof coating, the coating is classified according to the thickness, and is divided into a thick type, a thin type and an ultra-thin type. The fireproof coating for the thick steel structure is generally used in buildings with the fire endurance of more than 2 hours, the fireproof coating for the thick steel structure is mainly made of inorganic heat-insulating materials and does not expand when meeting fire, the temperature rise of steel is delayed by using the incombustibility, low heat transfer property and heat absorptivity of materials during decomposition, and the physical and mechanical properties of the steel structure are prevented from being damaged, so that the steel structure buildings are protected. At present, the research on the thick steel structure fireproof coating at home and abroad mainly focuses on the following four types: alkali metal silicate type coating, silica sol type coating, phosphate type coating, cement type coating.
The Chinese utility model with patent application number 88108089.6 relates to an organic polymer colloid composite material, which solves the problems of water resistance, fire resistance and corrosion resistance of the coating.
