Abstract
The utility model provides an anticorrosive composite biocoating of steel construction, include the coating on steel construction galvanizing layer on the surface, composite biocoating still includes: the priming paint layer is connected to the epoxy, the epoxy connect the priming paint layer be the spraying forms after sweeping sand preparation or broom -finish treatment on the galvanizing layer, lacquer layer in the middle of the epoxy cloud iron, the lacquer level is on the priming paint layer is connected to the epoxy in the middle of the epoxy cloud iron, the polyurethane finish layer, coat with lacquer on the layer in the middle of epoxy cloud iron the polyurethane finish level. Combine between this composite biocoating layer well, the whole thickness of film meets the requirements, uses under the adverse circumstances in high saline land district and does not cause any influence to the steel construction, quality accident such as also take place to return the rust, drop.
Description
Technical field
This utility model relates to steel beam column technical field of anticorrosion, especially relates to a kind of anticorrosive composite coating of steel structure.
Background technology
According to requirement in " Code for design of corrosion prevention of industrial buildings " GB50046-2008, it is in C5-M in equivalent ISO12944
Under environment steel construction service life more than 15 years time, can only by be significantly increased film thickness (more than 300 μm) or use
Spraying aluminum, zinc, alloying metal cover layer add coating and realize, and this will increase cost greatly.With " ISO 12944 1-8: protection
The anticorrosion of steel construction is protected by coating system " in for low-alloy carbon steel under C5-M environment as a example by coating system regulation, steel
Component design period is that the scheme that can be selected for of 15 years has A5M.01, A5M.03, A5M.05, A5M.08 tetra-kinds.And routine coating knot
Structure is in 1 year even more short time, it will occur that anticorrosive coat and zinc coat come off, seriously return the phenomenon of rust, need to be every in using
A period of time is repeated maintenance, it is impossible to meet code requirement.
Summary of the invention
The purpose of this utility model is to overcome shortcoming present in prior art, it is provided that a kind of anticorrosion of steel structure is compound to be coated with
Layer, to improve the resistance to corrosion of steel beam column, reduces maintenance cost, the technical scheme is that a kind of anticorrosion of steel structure is combined
Coating, including the Hot-dip Galvanizing Coating being coated on steel structure surface, it is characterised in that: described composite coating also includes: epoxy connects
Prime coat, described epoxy connect prime coat be carry out sweeping on described Hot-dip Galvanizing Coating sand process or after wharf's pavement quality spraying and
Become；Epoxy micaceous iron intermediate primer layers, described epoxy micaceous iron intermediate primer layers is positioned at described epoxy and connects on prime coat；Polyurethane finish
Layer, described polyurethane finish layer is positioned on described epoxy micaceous iron intermediate primer layers.
Technical characteristic of the present utility model also has: described epoxy connects the thickness of prime coat not less than 80 μm.
Technical characteristic of the present utility model also has: it is 40 μm that described epoxy connects prime coat thickness.
Technical characteristic of the present utility model also has: described polyurethane finish layer thickness is 40 μm.
Technical characteristic of the present utility model also has: described in sweep sand processing accuracy be Sa1 level.
The beneficial effects of the utility model are: 1) this composite coating Coating combination is good, and paint film integral thickness conforms to
Ask, use and steel construction is not had any impact under the adverse circumstances in high salt area, also return rust, the quality thing such as come off
Therefore；2) steel beam column after this coating is used can to reduce overall renovation maintenance times more than 4 times at life cycle (in 30 years), through surveying
Calculating, for the entirety of a whole audience outdoor steel structure, cost of overall renovation is about 4,000,000 yuan, therefore cost-saved 1600
Wan Yuan.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation, and wherein 1 is steel construction, and 2 is Hot-dip Galvanizing Coating, and 3 is that epoxy connects the end
Enamelled coating, 4 is epoxy micaceous iron intermediate primer layers, and 5 is polyurethane finish layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is illustrated.The utility model discloses one
Anticorrosive composite coating of steel structure, including the Hot-dip Galvanizing Coating 2 being coated on steel construction 1 surface, composite coating also includes: epoxy is even
Connecing prime coat 3, it is to carry out sweeping sand on Hot-dip Galvanizing Coating 2 to process or spray after wharf's pavement quality and form that epoxy connects prime coat 3；Ring
Oxygen cloud ferrum intermediate primer layers 4, epoxy micaceous iron intermediate primer layers 4 is positioned at epoxy and connects on prime coat 3；Polyurethane finish layer 5, polyurethane face
Enamelled coating 5 is positioned on epoxy micaceous iron intermediate primer layers 4.
In the present embodiment, epoxy connects the thickness of prime coat 3 and is not less than 80 μm, and it is 40 μm that epoxy connects prime coat 3 thickness,
Polyurethane finish layer 5 thickness is 40 μm.So, overall film thickness is about 160 μm.
Sweeping sand processing accuracy is Sa1 level.
Certainly, described above is not limitation of the utility model, and this utility model is also not limited to the example above, this skill
Change that the those of ordinary skill in art field is made in essential scope of the present utility model, retrofit, add or replace, also belong to
In protection domain of the present utility model.
