Abstract

The invention discloses a color-coated sheet resisting VHP (Vaporized Hydrogen Peroxide) oxidation. The color-coated sheet sequentially comprises a VHP oxidation resisting fine coating, a VHP oxidation resisting pre-coating, a first passivation layer, a galvanized sheet, a second passivation layer and a VHP oxidation resisting back coating from top to bottom, wherein the VHP oxidation resisting fine coating is polyester-polyamide resin formed by blending modification of nano Mo5Si3B and nano Ag2O; the content of the nano Mo5Si3B in the polyester-polyamide resin is 1.5-2.5 weight percent; the content of the nano Ag2O is 1.0-1.5 weight percent; the thickness of the VHP oxidation resisting fine coating is 15-20 microns. According to the scheme, a trace of nano-scale oxidation-resisting materials are added into a surface paint film of the color-coated sheet, so that the own good bending performance of a steel sheet is not influenced; the color-coated sheet has the characteristics of acid-base resistance, solvent resistance and VHP oxidation resistance; even in a VHP environment for a long time, the coatings are kept fine and smooth, the adhesion force is good, and the phenomena of pulverization, cracking and bubbling are avoided.

Description

technical field [0001] The invention relates to the field of special materials, in particular to an anti-VHP oxidation color-coated plate used in a pharmaceutical workshop. Background technique [0002] Color-coated steel plate, also known as color-coated steel plate, is a composite material, mainly composed of substrate and coating, which has the advantages of both steel plate and organic material. Good decoration, corrosion resistance, beautiful appearance and other advantages of the material have achieved good effects such as replacing wood with steel, efficient construction, and energy saving, so it has become a new type of decoration in the construction industry, shipbuilding industry, furniture industry, vehicle manufacturing industry, and electrical industry. Material. At present, color-coated steel sheets are mainly made of cold-rolled steel sheets, electro-galvanized steel sheets or hot-dip steel sheets as substrates, after surface degreasing, phosphating, and comp...
