Description

Technical Field

[0001] The utility model relates to the field of color steel plate structures, and more specifically, to a high temperature resistant PVC color steel plate. Background Art

[0002] Color steel plate refers to color-coated steel plate, which is a steel plate with an organic coating. Color steel plate is divided into single plate, color steel composite plate, etc., and is widely used in the walls and roofs of large public buildings, public factories, mobile houses, and integrated houses. Traditional color steel plates are insulated and fireproofed by filling rock wool, but rock wool is a soft material, which is not conducive to bearing high-intensity loads, resulting in insufficient bearing capacity of color steel plates, which are more susceptible to damage in extreme weather conditions. At the same time, traditional color steel plates are connected together by self-tapping screws fixed to steel purlins, or by installing connectors between adjacent color steel plates. This connection method makes it inconvenient to connect color steel plates. Utility Model Content

[0016] The utility model is further configured as follows: an anti-corrosion layer is arranged on the surface of the color steel plate body, and a reflective film is arranged on the surface of the anti-corrosion layer.

[0017] By adopting the above technical solution, the anti-corrosion layer and reflective film provided on the end surface of the color steel plate body can help improve the corrosion resistance and heat insulation of the color steel plate.

[0018] The utility model is further configured as follows: the fireproof rock wool is a directional rock wool board.

[0019] By adopting the above technical solution, the surface density of oriented rock wool is higher than that of ordinary rock wool materials; the high-density surface layer improves the overall wind resistance and tensile strength of the rock wool, thereby improving the overall strength of the color steel plate.
