Abstract
The utility model provides a book is scribbled to fluorine carbon polyester coloured silk, the front of base plate scribbles a chemical coating, priming paint, fluorine carbon polyester coating, automatically cleaning coating that the hydrophilicity is good in proper order, and the back of base plate scribbles the 2nd chemical coating, back of the body lacquer in proper order, a chemical coating and the 2nd chemical coating are no chromium chemical conversion coatings, priming paint and back of the body lacquer for anticorrosive epoxy layer, fluorine carbon polyester coating be fluorocarbon resin and polyvinylidene fluoride. The thickness of automatically cleaning coating be not less than 4 mu m, the base plate for plating aluminum plate or galvanized sheet. The utility model has the beneficial effect of simple structure rationally, can be used to the building decoration, the environmental protection is harmless, self -cleaning.
Description
Technical field
The utility model relates to sheet metal coiled material field, particularly relates to a kind of fluorine carbon polyester prepainted coil.
Background technology
Conventional coating be polyester coating, be made up of mylar, full methyl-etherified melmac, ester class and aromatic hydrocarbon solvent, adopt the mode of continuous roller coat to be coated on steel plate or aluminium sheet, after high-temperature baking, film-forming.Through the steel plate of paint or aluminium sheet because having the features such as dust-proof, antifouling, fungi-proofing.But all there is a large amount of chemical substances in the pre-treatment that these Coil Coating Products are used usually and post processing, deal with improperly and will produce a large amount of pollutions to environment, simultaneously, common colored steel is by absorption, constantly can precipitate formation pollution layer at coating surface, and, grieshoch can utilize that coating surface is micro-look under uneven, infiltrate in the space on surface, be still stored in paint film after rainwater evaporation and form dirt.
In addition, existing prepainted coil normally does the process of a underseal on surface, also the prepainted coil doing the above coating process such as underseal and painting layer is had, such prepainted coil has certain corrosion protection, can keep within the regular hour not by corrosion, but the time one is long, usual spent 5 years after, the coating of outside can be worn or corrode, cause the exposure of substrates of the inside in atmosphere, if air ratio is moister, is easy to oxidized or corrosion, has a strong impact on the attractive in appearance of prepainted coil and result of use.
Utility model content
The purpose of this utility model solves problem set forth above, provides a kind of fluorine carbon polyester prepainted coil.
The technical solution of the utility model is such:
A kind of fluorine carbon polyester prepainted coil, comprises substrate; The front of described substrate scribbles the automatic cleaning coating of the first immersion coating, priming paint, fluorine carbon polyester coating, good hydrophilic property successively, and the back side of described substrate scribbles the second immersion coating, back of the body paint successively;
Described first immersion coating and the second immersion coating are Chrome-free chemical conversion coating;
Described priming paint and back of the body paint are corrosion-proof ring oxygen layer;
As preferably, described fluorine carbon polyester coating is fluorocarbon resin and polyvinylidene fluoride.
As preferably, described substrate is alclad sheet or galvanized sheet.
As preferably, the thickness of described automatic cleaning coating is not less than 4 μm.
The beneficial effects of the utility model are as follows:
1, the fluorine carbon bond of fluorine carbon polyester coating is very stable, thus makes coating have good weatherability, corrosion resistance and wearability, improves the mechanical performance of prepainted coil;
2, by arranging Chrome-free chemical conversion coating, avoiding the Zincing passivation agent containing chromium and color coating masking liquid pollution sewer water body, affecting living environment;
3, make the surface of raindrop and prepainted coil form lower water contact angle by automatic cleaning coating, contact angle is less, and hydrophily is better, and rainwater takes away dust, thus reaches clean object.
Disclosed in the utility model, new material structures advantages of simple, can be used for construction and decoration, environmentally friendly, automated cleaning.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure:
1. substrate, 2. the first immersion coating, 3. priming paint, 4. fluorine carbon polyester coating, 5. automatic cleaning coating, 6. the second immersion coating, 7. back of the body paint.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
