The composite coating comprises a bottom layer attached to a metal substrate, a closed coating, a middle layer, an outer layer and a prevention layer, wherein the bottom layer is a nickel-chromium-aluminium alloy wire thermal spraying metal layer; the closed coating is a nanometer epoxy powder coating spraying plastic layer; the middle layer is a fireproof power coating spraying plastic layer; the outer layer is a high chlorinated polyethylene coating layer; the protection layer is made of a ceramic material or a high polymer material. The composite coating provided by the utility model has excellent corrosion prevention and fire prevention functions, and has a decoration function.
Description
Technical field
The utility model relates to a kind of compound coating, relates in particular to a kind of compound coating of corrosion protection of metal surface.
Background technology
High speed development along with modern society, urbanization process has obtained great promotion, many high buildings and large mansions stand each the large, medium and small city in the world, and the metal of the support of formation building, such as steel, obtained unprecedented large-scale application, the world is more and more stronger to the demand of these metals.Because the characteristic that metal is corroded easily; a lot of steel etc. obtain damaging owing to protection is improper at the metal of class; have to discarded or be driven into steel melting furnace again refined; this will cause great waste to enterprise and even entire society; thereby; need to process the metallic surface, with the protection metal.
At present, the technology that coating processes is processed in the metallic surface make great progress, thereby all kinds of compound coatings that can etch-proof metallic surface have obtained people's energetically demand.
The utility model content
The purpose of this utility model provides a kind of compound coating of corrosion protection of metal surface, and this compound coating can protection against corrosion, can play again the function of attractive, decorative, possesses in addition fire-proof function.
The technical solution adopted in the utility model is as follows:
A kind of compound coating of corrosion protection of metal surface; comprise the bottom, seal coat, middle layer, skin and the protective layer that are attached to successively on the metal substrate; wherein; described bottom is nichrome aluminum alloy silk thermospray metal level; described seal coat is nanometer epoxide powder coating plastic-blasting layer; described middle layer is fire-proof powdery paint plastic-blasting layer, and described skin is the highly-chlorinated polyethylene coating, and described protective layer is stupalith or macromolecular material.
Preferably, the thickness of described bottom is 0.12-0.16mm.
Preferably, the thickness of described seal coat is 0.009-0.02mm.
Preferably, the thickness in described middle layer is 0.04-0.06mm.
Preferably, described outer field thickness is 0.05-0.07mm.
Preferably, the thickness of described protective layer is 0.03-0.05mm.
Composite coating structure of the present utility model is tight, strong adhesion, and the thermospray metal level has good anti-corrosion capability; The seal coat that nanometer epoxide powder coating plastic-blasting layer consists of has sufficient perviousness and sealing effect and gives prominence to; Adopt fire-proof powdery paint plastic-blasting layer as the middle layer, can play good fireproofing function; Skin is the highly-chlorinated polyethylene coating, has good decoration functions; Protective layer is stupalith or macromolecular material, can play a protective role to the metallic surface, owing to be stupalith, also can play certain thermal-insulation function.
Description of drawings
