Abstract
A kind of sheet metal corrosion-inhibiting coating structure, including board substrates, it is sequentially coated with prime coat, floating coat and top coat layer on basic unit, it is characterized in that: described top coat layer is twice, including being positioned at the aliphatic acrylic polyurethane finish layer of nexine and being positioned at the fluorine carbon finishing paint layer on top layer.This solution provides a kind of sheet metal corrosion-inhibiting coating structure, paint film weather resisteant does not have big change, but the adhesive force of paint film is much better, and anti-corrosive properties and the dicoration of paint film are more stable.
Description
Technical field
This utility model relates to a kind of coating structure, particularly to a kind of sheet metal corrosion-inhibiting coating structure.
Background technology
Cargo tank, underground piping, underwater facility etc., owing to contacting with corrosive substance for a long time, to sea water resistance, resistance to crude oil, resistance to
The performances such as burn into is antirust propose higher requirement.But the protective coating of the cargo tank of routine, underground piping, underwater facility, be
Three-layer protection structure at surface-coated seal coat, intermediate coat and the finish paint of metal base.Tradition fluorine carbon finishing paint needs overcoating
Once, on fluorine carbon finishing paint after overcoating fluorine carbon finishing paint, adhesive force before paint film may will not be fine, cause paint film anti-corrosive properties and
Ornamental unstable.
Utility model content
The purpose of this utility model is to provide a kind of sheet metal corrosion-inhibiting coating structure, and paint film weather resisteant does not have big
Change, but the adhesive force of paint film is much better, and anti-corrosive properties and the dicoration of paint film are more stable.
Above-mentioned purpose of the present utility model has the technical scheme that a kind of sheet metal corrosion-inhibiting coating
Structure, including board substrates, is sequentially coated with prime coat, floating coat and top coat layer on basic unit, described top coat layer is twice, bag
Include the aliphatic acrylic polyurethane finish layer being positioned at nexine and the fluorine carbon finishing paint layer being positioned at top layer.
By using technique scheme, aliphatic acrylic polyurethane finish has high adhesion force, good mechanicalness
Can, paint film good decorative property, paint film flat smooth after dry, facilitate fluorine carbon finishing paint overcoating.
Preferably, described prime coat is epoxy zinc rich primer layer.
By using technique scheme, epoxy zinc rich primer natural drying block, adhesive force is strong, and anti-corrosion capability is strong.
Preferably, described floating coat is epoxy micaceous iron intermediate primer layers.
By using technique scheme, epoxy micaceous iron intermediate coat can be protected priming paint paint film, strengthen the guarantor of whole coating
Protect performance.
Preferably, described prime coat thickness is at 50-80 micron.
By using technique scheme, this thickness can effectively cover substrate surface, favorable rust preventing effect.
Preferably, described epoxy micaceous iron intermediate primer layers is twice overcoating, and gross thickness is at 100-200 micron.
By using technique scheme, this thickness protection priming paint paint film is effective.
Accompanying drawing explanation
Fig. 1 is the coating structure figure of the present embodiment.
Reference: 1, basic unit；2, prime coat；3, floating coat；4, top coat layer；4a, aliphatic acrylic polyurethane finish
Layer；4b, fluorine carbon finishing paint layer.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As it is shown in figure 1, a kind of sheet metal corrosion-inhibiting coating structure, including basic unit 1, it is provided with at the bottom of epoxy zinc-rich on basic unit 1
Enamelled coating 2, thickness is at 50-80 micron；Being floating coat 3 on prime coat 2, floating coat 3 is in the epoxy micaceous iron of twice overcoating structure
Between enamelled coating, gross thickness is at 100-200 micron；Being top coat layer 4 on floating coat 3, top coat layer 4 is also double-layer structure, including being positioned at
The aliphatic acrylic polyurethane finish layer 4a of nexine and the fluorine carbon finishing paint layer 4b being positioned at top layer.
Epoxy zinc rich primer is with epoxy resin, zinc powder, silester as primary raw material, thickening agent, filler, auxiliary agent, molten
The sapecial coating of the composition such as agent;Epoxy micaceous iron intermediate coat is double-component.Composition one is by epoxy resin, micaceous iron oxide, antirust face
Material, organic solvent are formulated;Composition two is firming agent.Composition one: composition two=100:10 (weight ratio);Aliphatic polyurethane
Finish paint be with aliphatic isocyanate component and senior acrylic resin, pigment, auxiliary agent and solvent etc. composition paint vehicle as hydroxyl
Component two-component air-dry coating;Fluorine carbon finishing paint be with senior fluorocarbon resin, Special Resin, main film forming substance double-component from
Dried paint.Big due to the fluorine element electronegativity introduced due to fluorine resin coating, carbon-fluorine bond can be strong, has especially advantageous every property
Energy.Weatherability, thermostability, lower temperature resistance, chemical proofing, and there is the non-stick and low abrasiveness of uniqueness.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
