Description
Technical field
The utility model relates to metallized film fields, and in particular to a kind of capacitor metallized film.
Background technique
Metallized film capacitor is that (common thin-film material has: poly- ethyl ester, polypropylene, polycarbonate with organic plastics film
Deng) medium is done, one or more layers metal film (is deposited instead of conventional metals on the surface of organic plastics film with metallized film
Foil) electrode is done, the capacitor made of the modes such as winding has excellent electrical characteristic, high stability, long-life and volume
The characteristics such as small, can be used for a variety of places.
What metallic film capacitor industry generallyd use at present is zinc and aluminum composite metal thin film coating technique, and zinc is made
It is difficult directly to be deposited to epilamellar, it is necessary to first plate one layer of metal and do bottoming because of its poor adhesive force for the primary metal layer of pole plate
Layer.What current metallic film capacitor industry at home generallyd use is zinc-aluminium composition metal thin film technique, i.e., in vacuum
Under the conditions of first plate one layer of metallic aluminium on basement membrane and be used for bottoming, then plate one layer of metallic zinc again, form one in membrane surface in this way
A aluminum and zinc composite deposite, and capacitor is made using it as pole plate.The disadvantage of zinc-aluminium composition metal thin film technique is
Outermost metallic zinc is easy to that oxidation reaction occurs with the oxygen in air, so that the performance of capacitor product is reduced, and
A kind of silver, zinc, aluminum composite metal film have been released in the world, i.e., then one layer of silver (belonging to noble metal) before this on basement membrane is again
One layer of zinc, is finally one layer of aluminium again, and aluminium layer and air catalytic oxidation form AL2O3Protective layer, the AL2O3Protective layer can prevent
Internal metal layer continues that oxidation reaction occurs, to guarantee the service performance of metallized film.This silver, zinc, the compound gold of aluminium
Also there is a small amount of introduction in the categoryization thin film technique country, but since the technology is using noble silver as bottoming, with high costs, institute
It is not widely adopted at home with the technology.Therefore, in order to avoid disadvantage existing in the prior art, it is necessary to existing skill
Art makes improvement.
Utility model content
The purpose of the utility model is to overcome shortcoming and deficiency in the prior art, provide a kind of at low cost, anti-oxidant
The strong capacitor metallized film of property.
The utility model is realized through the following technical scheme: a kind of capacitor metallized film, including basement membrane
Layer, further includes the first aluminium layer being covered on the base membrane layer, the zinc layers being covered on first aluminium layer, is covered in the zinc
The second aluminium layer on layer and the AL being covered on second aluminium layer2O3Protective layer.
Further, the weight of first aluminium layer be first aluminium layer, zinc layers and the second aluminium layer total weight 1%~
2%.
Further, the weight of the zinc layers is the 90%~95% of first aluminium layer, zinc layers and the second aluminium layer total weight.
Further, the weight of second aluminium layer be first aluminium layer, zinc layers and the second aluminium layer total weight 4%~
8%.
Compared with the existing technology, the utility model efficiently solves zinc by doing bottoming metal with one layer of aluminium on basement membrane
Poor adhesive force the problem of, and it is with high costs, difficult dramatically to improve silver, zinc, aluminum composite metal film manufacturing techniques
With universal problem.Outer layer increases aluminium layer, and aluminium layer and air catalytic oxidation form AL2O3Protective layer, the AL2O3Protective layer can be with
Metal layer inside preventing continues that oxidation reaction occurs, and solves the oxygen of the domestic zinc-aluminium composition metal film generally used at present
Change problem.
Detailed description of the invention
