Abstract
The utility model discloses a pure aluminum-zinc thickened metallized film for capacitors, which comprises a film medium layer, an aluminum metallized film layer and a zinc metallic thickened layer. The aluminum metallized film layer is formed by coating aluminum metal materials on the film medium layer, edges are provided after combining the aluminum metallized film layer and the film medium layer, the zinc metallic thickened layer is formed by coating zinc metal materials on the aluminum metallized film layer, and the zinc metallic thickened layer is disposed on the metallized edges after combining the aluminum metallized film layer and the film medium layer. The structural pure aluminum-zinc thickened metallized film is adapted to the tendency of the existing unleaded metal spraying process for producing capacitors, the metal spraying combination effect can be better by using zinc and aluminum-zinc alloy in metal spraying, and in terms of deposition process, the pure aluminum-zinc thickened metallized film further has the advantages of simple process and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of metallized film, particularly relates to a kind of thickened metalized film of fine aluminium zinc that is used for capacitor.
Background technology
Capacitor is one of a large amount of electronic components that use in the electronic equipment, is widely used in being coupled bypass, filtering, resonant tank, power conversion, aspects such as control circuit every directly.Film capacitor is a kind of of capacitor, because its volume low capacity is big, purposes is comparatively widely arranged, can form different series of products, as high specific energy energy storage capacitor, anti-electromagnetic interference capacitor, radioresistance capacitor, safety film capacitor, long-life capacitor, highly reliable capacitor, high pressure all-film power capacitor etc.Film capacitor can be divided into takeup type and stacked two kinds from the processing mode, no matter be takeup type film capacitor or stacked film capacitor, all be to need to adopt metallized film to be made, this metallized film has then generally included metal level and thin film dielectrics layer, when making, thereby be that the metal level plated film has been formed metallized film on the thin film dielectrics layer.When adopting metallized film to make capacitor, usually will be at the metallized ends limit of metallized film metal spraying, in order to reach metal spraying effect preferably, a kind of metallized film of prior art is in the thickening of the metallized ends limit of this metallized film, its metal level of the metallized film of this thickening pattern generally adopts aluminium lamination, thickening layer also adopts aluminium lamination, it is fine aluminium aluminium thickening pattern, continuous development along with the metal spraying technology, the metal spraying metal is more and more with zinc and red brass, thereby exists the drawback of metal spraying poor effect.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, a kind of thickened metalized film of fine aluminium zinc that is used for capacitor is provided, makes the metal spraying metal have and combine better effect, simultaneously with the upset end on metallization limit, it is simple also to have technology, the characteristics that cost of manufacture is low.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of thickened metalized film of fine aluminium zinc that is used for capacitor comprises:
One thin film dielectrics layer;
One aluminum metallization rete forms on the thin film dielectrics layer for adopting the aluminum metallic material plated film; This aluminum metallization rete stays the limit with being provided with after the thin film dielectrics layer combines;
One zinc metal thickening layer forms on the aluminum metallization rete for adopting zinc metal material plated film; Metallized ends limit after this zinc metal thickening layer is located at described aluminum metallization rete and the thin film dielectrics layer combines.
A kind of thickened metalized film of fine aluminium zinc that is used for capacitor of the present utility model, it is plated film aluminum metallization rete and constitute basic metallized film on the thin film dielectrics layer, and add a bit of zinc metal thickening layer of plating on the metallized ends limit of this metallized film, thereby constituted the thickened metalized film of fine aluminium zinc, when adopting the thickened metalized film of this fine aluminium zinc to make capacitor, the metal spraying metal makes metal spraying in conjunction with better effects if with zinc and red brass.
The beneficial effects of the utility model are, owing to adopted a thin film dielectrics layer, one aluminum metallization rete, one zinc metal thickening layer constitutes the thickened metalized film of fine aluminium zinc, and the aluminum metallization rete forms on the thin film dielectrics layer for adopting the aluminum metallic material plated film, this aluminum metallization rete stays the limit with being provided with after the thin film dielectrics layer combines, zinc metal thickening layer forms on the aluminum metallization rete for adopting zinc metal material plated film, metallized ends limit after this zinc metal thickening layer is located at described aluminum metallization rete and the thin film dielectrics layer combines, the thickened metalized film of fine aluminium zinc of this structure, when making capacitor, be adapted to the trend of the unleaded technology of present metal spraying, the metal spraying metal uses zinc and its metal spraying of red brass in conjunction with better effects if, simultaneously, from the evaporation process angle, it is simple also to have technology, the advantage that cost of manufacture is low.
Below in conjunction with drawings and Examples the utility model is described in further detail; But a kind of thickened metalized film of fine aluminium zinc that is used for capacitor of the present utility model is not limited to embodiment.
