Abstract
An oil type oxidation barrier film structure for metalized capacitors, which relates to a film for metalized capacitors, comprises a substrate film unit layer formed by connected substrate film units, an aluminized layer is plated on the substrate film unit layer, a galvanized layer is plated on the aluminized layer, and a silicone oil protective layer is arranged on the galvanized layer. Since the silicone oil protective layer is arranged on the whole metal layer to isolate the air, aluminum and zinc are prevented from being oxidized by the air, consequently, the oxidation resistance of the metalized film is enhanced, the film can be prevented from being oxidized and broken down in the process of capacitor production, and the quality of a capacitor made of the metalized film is greatly increased. Meanwhile, the oil type oxidation barrier film structure also solves the problem that the large-capacity capacitor can be broken down due to overlarge capacity and difficult heat dissipation. The silicone oil protective layer has the functions of tight bonding and heat dissipation, and enhances the firmness between the plated layers, thus effectively preventing the metal layers from shedding.
Description
Technical field
The utility model relates to a kind of thin film for metalized capacitor, is specifically related to a kind of metallized capacitor with oily formula oxidation barrier film structure.
Background technology
Existing thin film for metalized capacitor, be on as the basement membrane of dielectric material, under high vacuum condition, to plate metal polar plate with coating machine, pole plate can be divided into aluminium coat and zinc coating is two-layer, because of it has unique self-healing feature, be widely used in and make all kinds of electric power compensations usefulness or motor starting AC capacitor and DC filter capacitors.The self-healing performance of metallized film uniqueness can obviously be improved the proof voltage ability and the useful life of metallic film capacitor.Because the fusing point of zinc is lower than aluminium, easilier when thermal breakdown of capacitor, to bring into play, self-healing property is better, so aluminium zinc composition metal film has better voltage endurance than the aluminum metallization film.Yet its structure of the film that capacitor is used in the prior art is comparatively single, and resistance to pressure, self-healing property are poor.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of oxidation resistance is good, self-healing ability is strong metallized capacitor with oily formula oxidation barrier film structure.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of metallized capacitor comprises the basement membrane elementary layer that is connected through the basement membrane unit with oily formula oxidation barrier film structure, is coated with layer of aluminum coating on the basement membrane elementary layer, is coated with one deck zinc coating on the aluminium coat, and described zinc coating is provided with one deck silicone oil protective layer.
The thickness of described basement membrane elementary layer is 5～20 μ m, and the basement membrane spacing that described basement membrane unit is connected is 4～7mm, and the thickness of basement membrane unit is 12～650mm, and the number of described basement membrane unit is 30～100.
The beneficial effects of the utility model are: the utility model is provided with one deck silicone oil protective layer on whole metal level; just as isolated with air; avoid the aluminum and zinc oxidation by air; thereby improve the oxidation resistance of metallized film; it is oxidized breakdown to avoid film occurring in the process of making capacitor; improved the quality of the capacitor of this metalized film making greatly; it is excessive simultaneously also to have solved the large value capacitor capacity; the heat difficulty is distributed and is caused the problem that punctures; the silicone oil protective layer has played combines closely and heat sinking function; increase the fastness between each coating, prevent that effectively metal level from coming off.
Description of drawings
Fig. 1 is the utility model structure cut-away view.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1; a kind of metallized capacitor is with oily formula oxidation barrier film structure; comprise the basement membrane elementary layer 1 that is connected through the basement membrane unit; be coated with layer of aluminum coating 2 on the basement membrane elementary layer 1, be coated with one deck zinc coating 3 on the aluminium coat 2, zinc coating 3 is provided with one deck silicone oil protective layer 4; the thickness of basement membrane elementary layer 1 is 5～20 μ m; the basement membrane spacing that the basement membrane unit is connected is 4～7mm, and the thickness of basement membrane unit is 12～650mm, and the number of basement membrane unit is 30～100.Silicone oil protective layer 4 is isolated with air aluminium coat 2 and zinc coating 3, has improved whole antioxygenic property, has guaranteed capacitor the high-quality of metallized film, thereby reduces metallized film because the problem that withstand voltage deficiency and surface oxidation cause capacitor to scrap.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
