Abstract
A composite coating on metal surface to prevent corrosion has the characteristics that the composite coating tightly covering the metal surface consists of a bottom layer, an intermediate layer and an outer layer. The bottom layer of the composite coating is a hotly sprayed metal layer, the intermediate layer is an epoxy powder coating layer and the outer layer is a thermosetting powder coating layer.
Description
Technical field
The utility model relates to a kind of compound coating that is used for the corrosion protection, is specifically related to the compound coating that a kind of thermospray metal level adds the overbrushing layer structure of powder coating plastic-blasting layer, belongs to the protecting metallic surface technical field.
Background technology
The method that adopts coating technology that corrosion prevention is carried out in the metallic surface is of long duration, and as all kinds of coating, metal thermal spraying coating, organic coating coating etc., has all obtained protection effect preferably.
With the iron ratio; zinc, aluminium etc. all are active very strong metals; adopt thermospray zinc, aluminium or its alloy to form metallic coating and can form excellent protection the iron and steel metal; but the metallic coating that forms owing to metal thermal spraying is to be attached on the surface of steel substrate by the particulate that the deposite metal is atomized into 4～40 μ m; coating structure is more loose; corrosive medium can permeate easily and be immersed in steel substrate, forms corrosion, and its surface must adopt sealing paint to carry out sealing treatment.Closed material generally adopts liquid coating or all kinds of paint at present, in actual applications, especially under abominable corrosive environment, the steel and iron member of the above-mentioned processes of many employings, corrosive medium still can penetrate its outer closure layer quickly and corrode metal base, liquid coating or all kinds of paint also all have environmental pollution more or less in addition, and its construction cost height, coating quality also are difficult for guaranteeing.
Powder coating does not contain solvent, has nearly 100% utilization ratio, efficient, environmental protection, energy-conservation, economic, and its coating has excellent physical and mechanical performance and Nai Hou corrosion resistance, and recent two decades has worldwide been obtained swift and violent development.
Adopt at present the epoxy powder coating that contains flaky material to make the sealer coat of thermospray metallic coating, adopt again simultaneously to have and decorate and the protective effect thermosetting powder coating(s) is made outer field technical project and be yet there are no disclosed report.
Summary of the invention
The purpose of this utility model provides a kind of compound coating that is used for the corrosion protection, i.e. thermospray adds the compound coating of plastic-blasting, overcomes the deficiency that existing thermospray and the design of sealing compound coating exist.The design of this compound coating is perfect, resistance to corrosion strong, have good decoration and protective effect.
The utility model solves by the following technical programs: a kind of compound coating that is used for the corrosion protection, combining closely in the metallic surface is coated with by bottom, middle layer and the outer compound coating of forming, the bottom of compound coating be thermospray metal level, middle layer be epoxide powder coating plastic-blasting layer, outer be thermosetting powder coating(s) plastic-blasting layer.
The thermospray metal level of above-mentioned bottom, it can be the metal level (as aluminium, zinc, magnesium etc.) of single component, also can be multi-component alloy layer (as aluminum magnesium alloy, aluminium zinc, aluminium zinc magnesium alloy etc.), can also be multiple single component metal level stack (as first aluminium-plated back spray zinc, earlier spray zinc and then aluminium-plated magnesium alloy, can also be aluminium-plated aluminium-plated magnesium alloy again etc. behind the spray zinc earlier), the number of plies of metal thermal spraying coating can be individual layer, bilayer or multilayer, and the total thickness of its coating is 40-200 μ m.
What epoxide powder coating plastic-blasting layer used in the middle of above-mentioned is the thermosetting powder coating(s) that contains Resins, epoxy and a kind of flaky material at least, and the thickness of coating is 40-100 μ m.
What above-mentioned skin used is the thermosetting powder coating(s) that contains following a kind of character material at least: UV light absorber, oxidation inhibitor, tetrafluoroethylene, glass fibre, sheet color stuffing, nano material, the thickness of outer coating are 60-120 μ m.
Protected base material can be existing various metal material, and its surface adopts existing various surface treatment methods to carry out, and reaches cleaning surfaces, inclusion-free and has certain roughness.
The beneficial effects of the utility model are: the thermospray metal level has good corrosionproof protection ability, can be according to the protection needs of metal base, select single metal thermal spraying layer, the alloy layer of two or more metals, the stack compound coating of the single thermally sprayed coating of multiple metal, make full use of the anodic protection effect of reactive metal or the excellent anti corrosion protection of various metal alloys: adopt the lower and epoxide powder coating that dose some flaky materials of viscosity to do sealer coat, when being heating and curing, when the fused powder coating can be infiltrated up in the space of thermally sprayed coating fast, obtain good sealing effect, and flaky material wherein is (as the inert mica powder, oxide platelet filler salt and active sheet metallic substance such as zinc metal sheet, aluminium flake and other alloy slices) not only improved the degree of compactness of coating, more can play excellent shielding effect, stop even cut off the infiltration circuit of corrosive medium, when adopting the reactive metal sheet, can also consume corrosive medium and can utilize corrosion product further to intercept the infiltration of corrosive medium; Skin can be according to the protection needs, adopt ornamental or functional thermosetting powder coating(s) coating, UV light absorber, oxidation inhibitor, tetrafluoroethylene, glass fibre, sheet color stuffing, the nano material of adding can play respectively anti-sun exposure, anti-aging, increase effect wear-resisting firmly, corrosion-resistant or that coating is self-cleaning, allow external coating (EC) have excellent physical and mechanical performance and weather-proof ageing resistance, realize decorating and the unification of protecting.The utlity model has good prospects for application.
