Abstract

The invention provides a preparation method of a steel structure fireproof paint by taking expanded and vitrified small ball as a base material, which is characterized in that on the basis of a traditional organic inorganic clad steel structure fireproof paint, and expanded and vitrified small ball and phenolic resin are used for obtaining the steel structure fireproof paint with excellent performance. According to the invention, expanded and vitrified small ball in the inorganic component replace a traditional lightweight aggregate, thereby the paint has the advantages of low density, high strength, stable physical and chemical performance, and has excellent performances of aging resistance and weatherability, heat insulation, fire resistance, sound insulation and insulation; phenolic resins can replace a traditional film forming agent in the organic component, no fire retardant is applied, so that the coating has the advantages of difficult combustion, good heat stability, low smoke, low toxicity, high mechanical strength, and strong anti-corrosion capability and weather resistance. The paint overcomes the disadvantages of poor flame resistance and toxic flue gas release due to thermal decomposition of the common organic resin.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings for steel structures, in particular to a preparation method for fireproof coatings for steel structures using expanded vitrified microbeads as base materials. Background technique [0002] The steel structure has the advantages of light weight, easy installation, short construction period, high degree of mechanization of manufacturing and installation, etc., and is favored by the construction industry. It has been widely used, especially with the advancement of housing industrialization, light steel structures will be more widely used. However, steel structures have fatal flaws: poor fire resistance, and their mechanical properties, such as bearing capacity, yield point, tensile strength, and modulus of elasticity, decrease sharply with increasing temperature. The strength of ordinary steel begins to decrease rapidly at 300-400°C; at 500°C, its strength decreases to 40%-50% of the orig...
