Description
Technical field
The utility model belongs to electric capacity technical field of membrane, and in particular to a kind of Wave-cut polypropylene of resistance to 110 DEG C of high temperature
Film.
Background technology
Thin film capacitor is also known as plastic sheeting electric capacity, and it is using plastic sheeting as dielectric.Thin film capacitor is due to very
More excellent characteristic, therefore be a kind of capacitor of excellent performance.Its property such as main is as follows：Nonpolarity, insulation impedance is very high,
Frequency characteristic is excellent, and dielectric loss very little.The advantages of based on the above, so thin film capacitor is widely used in simulation electricity
Lu Shang.For traditional metallization film in being produced applied to inner core of capacitor, the metal edges of film are mostly linear structure, are being carried out
Adhesive force is poor during metal spraying technique, contact is bad and resistance is bigger than normal, therefore capacitor finished product has that loss is big, easily generates heat, draws
The defects of line is easy to fall off so that corresponding properties of product decline.
A kind of metallized film (the notification number of Wave-cut of patent：CN203456303U a kind of Wave-cut) is disclosed
Metallized film, as the inner core membrane material of capacitor, by insulating basement membrane and the metal film of integral plating is formed thereon, and the metal
Change film and stay side in outer dewiness provided with insulating basement membrane, it is characterised in that：The metallized film is staying side edge, metal film edge
Or Liu Bian and metal film edge are cut and are set to undaform sideband.The utility model is wavy by the way that metal film edge is arranged to, and increases
Add the contact area with terminal, improve the adhesive force of product, but it is narrow at the wavy crest of in general, also it is not easy to
Stickup after polypropylene film coiling.
The problem of being existed according to prior art, the utility model provide what a kind of convenience was connected with terminal, with it is larger around
Roll up a kind of Wave-cut polypropylene film of resistance to 110 DEG C of high temperature of tension force.
Utility model content
The utility model provides following technical scheme：
A kind of Wave-cut polypropylene film of resistance to 110 DEG C of high temperature, including polypropylene basement membrane, apply on the polypropylene basement membrane
Be covered with metal film, the metal film includes the side of staying that part is exposed at outside polypropylene basement membrane, it is described stay side edge be it is wavy,
The wavy wavelength is identical with wave height, and the wavy wave height stays 2/3rds of hem width degree to be described.
Preferably, the width for staying side is 1-2cm.
Preferably, the sharp corner for staying side does fillet processing.
Preferably, the polypropylene basement membrane includes some polypropylene film bars, the overlapped volume of polypropylene film bar
Composition film body is knitted, the edge of the film body is coated with polypropylene screen bound edge.
Preferably, the width of the polypropylene film bar is 1-3cm.
The beneficial effects of the utility model are：
1st, the utility model is improved to wavelength and wave height identical is wavy by metal film edge is wavy, makes metal edge
With larger contact area, convenient operation, wavy wave height is stay hem width degree 2/3rds, and wavy generation is worked as in guarantee
During tear, being covered in the epilamellar metal film of polypropylene will not be torn；
2nd, staying hem width to spend conference influences the volume of most enough curling electric capacity, too small that sound can be made to stay side to be stranded provided with Wavy phenomenon
Difficulty is general to set width 1-2cm more moderate；
3rd, because metal film is harder, therefore fillet processing ensures that polypropylene basement membrane will not be scratched crimping center；
4th, the film body being woven into by the superposition of polypropylene film bar has higher elasticity, and good coiling power, also allows for
Cutting is provided with polypropylene screen bound edge at film body edge prevents the superposition braiding structure of polypropylene film bar from coming off.
