Abstract

The invention discloses a fireproof and anti-corrosion bifunctional ultra-thin steel structure coating and a preparation method thereof. The fireproof and anti-corrosion bifunctional ultra-thin steel structure coating is prepared from the following raw materials by weight percentage: 1-30% of chloroprene rubber adhesive, 1-30% of melamine, 1-20% of pentaerythritol, 1-30% of pigment and filler, 1-50% of 1000# solvent gasoline,1-20% of ammonium polyphosphate, 1-15% of chlorinated paraffin solution with a chlorine content of 70%, 1-10 % of acrylic resin, 0.1-5% of amino resin, 1-10% of raw vermiculite, 1-10% of charring aid, 0.1-5% zinc borate and 0.1-10% of auxiliary agent. The fireproof and anti-corrosion bifunctional ultra-thin steel structure coating has the advantages of greatly improved maximum flexibility, fire resistance limit, binding strength and fire resistance time, good flame retardance, corrosion resistance, water resistance and weather resistance and low cost; and more importantly, the coating is safe and environmentally-friendly, and the coating layer formed by the coating is light and thin, thus truly embodying the fireproof and anti-corrosion dual functions and ultrathin characteristic.

Description

technical field [0001] The invention relates to an ultra-thin steel structure coating with dual functions of fire prevention and anticorrosion and a preparation method thereof. Background technique [0002] Economic and social development has promoted the development of the construction industry. Large-scale buildings such as exhibition halls, terminal buildings, large shopping malls, stadiums, high-end hotels and industrial plants are increasing, and they are developing in a large and beautiful direction. The main load-bearing components Most are steel structures. [0003] For this reason, the fire protection of steel structures has attracted more and more attention. Although steel is a non-combustible material, its fire resistance is far worse than that of masonry structures and reinforced concrete structures. As the temperature increases, the mechanical strength of steel will decrease. When the temperature rises to the critical temperature of steel (generally 540°C), it...
