Embodiment 1

[0015] A method for improving the fire resistance of color steel tiles, comprising the following steps:

[0016] (1) Use 200-mesh and 400-mesh sandpaper to polish the protective paint on the surface of the color steel tile to roughness, and wipe it with oil solvent, which contains 0.5% urea and 1.5% ammonia water, and the rest is gasoline , after wiping, use oxalic acid solution with a mass concentration of 1.0% to scrub, and finally rinse with clean water and dry in hot air;

[0017] (2) Brush two layers of anti-rust primer on the surface of the color steel tile after surface treatment. In the primer, epoxy resin accounts for 45%, basic lead chromate accounts for 8.5%, and the first layer of anti-rust primer film The amount is 120 g / m2, and after brushing, dry it under hot air at 40°C for 4 hours, then apply the second anti-rust primer, the coating amount is 80 g / m2, and dry naturally after brushing;

[0018] (3) Spray the refractory material after the second primer is appli...

Embodiment 2

[0023] A method for improving the fire resistance of color steel tiles, comprising the following steps:

[0024] (1) Use 200-mesh and 400-mesh sandpaper to polish the protective paint on the surface of the color steel tile to roughness, and wipe it with oil solvent. The oil solvent contains 0.65% urea and 1.7% ammonia water, and the rest is gasoline , after wiping, use oxalic acid solution with a mass concentration of 1.1% to scrub, and finally rinse with clean water and dry in hot air;

[0025] (2) Brush 2 anti-rust primers on the surface of the color steel tile after surface treatment. In the primer, epoxy resin accounts for 46%, basic lead chromate accounts for 8.8%, and the first anti-rust primer film The amount is 125 g / m2, and after brushing, dry it under hot air at 45°C for 5 hours, then apply the second anti-rust primer, the coating amount is 85 g / m2, and dry naturally after brushing;

[0026] (3) Spray the refractory material 11 hours after the second primer is appli...

Embodiment 3

[0031] A method for improving the fire resistance of color steel tiles, comprising the following steps:

[0032] (1) Use 200-mesh and 400-mesh sandpaper to polish the protective paint on the surface of the color steel tile until rough, and wipe it with an oil solvent. The oil solvent contains 0.8% urea and 2.0% ammonia water, and the rest is gasoline. , after wiping, use oxalic acid solution with a mass concentration of 1.2% to scrub, and finally rinse with clean water and dry in hot air;

[0033] (2) Brush two layers of anti-rust primer on the surface of the color steel tile after surface treatment. In the primer, epoxy resin accounts for 48%, basic lead chromate accounts for 9.0%, and the first layer of anti-rust primer film The amount is 130 g / m2, and after brushing, it is dried under hot air at 50°C for 6 hours, and then the second anti-rust primer is applied. The film amount is 90 g / m2, and it is naturally dried after brushing;

[0034] (3) Spray the refractory material ...

Abstract

The invention relates to the technical field of color steel tile machining, and discloses a method for improving fire resistance of a color steel tile. A surface of the color steel tile is treated andis coated with a layer of heat insulation and fireproof material, so that the fireproof performance is enhanced, and damage of the high temperature to the performance of the color steel tile is prevented when fire occurs; the color steel tile has excellent comprehensive physical and chemical properties even at a high temperature of 800 DEG C, the tensile strength of the color steel tile is maintained at 1100-1200 N / mm<2>, the elongation of the color steel tile is in the range of 17-18%, the tearing strength of the color steel tile is in the range of 350-400 N / mm<2>, the coated fireproof coating layer is high in sunlight resistant intensity, the color steel tile can tolerate high-temperature sunning at the temperature of more than 60 DEG C, and also has a good anti-seepage effect, and no leakage phenomenon exists after the color steel tile is observed for 12 hours under the water pressure of 2.3 MPa, so that the method for improving fire resistance of the color steel tile has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of color steel tile processing, and in particular relates to a method for improving the fire resistance of color steel tiles. Background technique [0002] Color steel tile, also known as: color profiled tile, is a profiled plate that is made of color-coated steel plate and cold-bent into various wave shapes by rolling. It is suitable for roofs, walls, and interior and exterior wall decoration of industrial and civil buildings, warehouses, special buildings, and large-span steel structure houses. It has the characteristics of light weight, high strength, rich color, convenient and quick construction, and earthquake resistance. It has been widely used Promote apps. Color steel tile building materials have been recognized by everyone. Color steel tile is currently the most widely used color steel tile building material. It is widely used in factory building construction and temporary accommodation due to its ...
