Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a content consisting of a metallized plastic film or seed.

In general, metallized plastic film is used as metallized plastic film. If tl
The metallized plastic film used is a plastic film that is used as the dielectric of the capacitor, and a metal film is directly formed by vacuum deposition. I'm there.

The plastic film fujiji, which functions as a dielectric,
Bori ethylene terephthalate, alpha♂ren,? Polyethylene, carbon carnate, 11I lifted ethylene, and films with high electrical insulation properties are used. Therefore, due to the high electrical insulation properties of plastic ivy film, we use insulating paper tubes as the dielectric material! However, a higher potential gradient can be obtained.

However, it is also possible to directly deposit metal tMtf by this vacuum deposition.
In the bIl manufacturing method, which is applied to the surface of the Rustituta film, during metal vapor deposition, the metal tends to bite into the plastic film, which serves as a dielectric, in the form of particles due to the phenomenon of central boiling of the molten metal. If this is made into a capacitor,
The corrosive gold III biting into the dielectric comes close to the opposing electrical connection, causing poor insulation in the capacitor.

As a result, 41G4 glass film capacitors do not have the high electrical insulation properties of the dielectric plastic film due to this poor insulation, which adversely affects the capacitor's withstand voltage and shortens its lifespan when using high voltages. The characteristics were not reliable.

The metal object that causes this insulation failure is the key to van as a metallized plastic film tube Koydenna element, or 11! After 41.5 times, the working voltage of the capacitor is 41.
By applying a high voltage of 5 to 4 degrees to the metallized plastic film for a short period of time, a kind of dielectric breakdown phenomenon occurs, and the smoke current is removed by RK, which improves the electrical imaging property. Partial K11 bales are made. However, the area removed by such a short circuit RK is the unused part of the deposited metal.
Ik scattering and holes in the nine-electrode plastic film caused by smoke currents cannot weigh against the inherent high electrical insulation properties of the plastic film.

In view of this situation, the present inventors have decided to use the above-mentioned vacuum evaporation method to produce a capacitor with 4tL9 insulation, which is made from a metallized plastic film obtained by directly forming a metallized film on a delaminate ivy film. As a result of intensive research, it was discovered that the above-mentioned problems could be overcome by using a transfer method, an electric discharge treatment, and a metallized plastic film or sheet obtained by laminating tube layers. I discovered what I could do and completed this project.

Therefore, an object of the present invention is to provide a new method for producing condensate.

Another object of the present invention is to provide a new capacitor tube which improves insulation failure and has high reliability S+ variation in life characteristics.

That is, a gold vapor-deposited film was formed on -1 of a glass film toe shaft sheet with a smooth surface, which was used as a supporting fiI4t, and on the other hand, one side of the electrically conductive base material was Alternatively, both lfis are subjected to electrical discharge treatment for 10 days, and the two thus obtained are subjected to heat and pressure without intervening an adhesive so that the Kinase-deposited film and the corona discharge treatment come into contact with each other. The gold-chloride plastic 2 film obtained by transferring the vapor-deposited metal film by peeling off the support material from the adhesive obtained in the next step is made into a sheet. By rolling or multiplying
Can be built.

Thus, according to the present invention, the insulation film made by combining the dielectric process and the corona discharge treatment can be used to reduce the thermal insulation defects caused to conventional capacitors by using the sheet. - can be avoided by 1, and an excellent capacitor with a long service life can be obtained.

In addition, in the present invention, the Fi-saving W4 vapor deposition test and the monoconductive base material can be directly applied without using an adhesive! Due to the presence of the adhesive O, the drawback of increased capacitor volume can be avoided. Therefore, it is possible to obtain a complete dish.

In the method of the present invention, a metal vapor deposition film is first formed on a support substrate, and this can be done by using a conventionally known vapor deposition method.
Zinc, gold, steel, steel, nickel, etc. can be used, and 4% polypropylene-reethylene can be used as the supporting base material.

Corona discharge treatment can also be carried out according to known techniques, and the monoconductive substrate to be treated with corona discharge is
The front of the glass film may be any sheet that can be activated by K, a film or sheet of non-polar polymer material such as q#4-lyethylene, Isss fillet/etc. Advantageously, films or sheets of polar molecular materials such as ethylene terephthalate (% zl-), 497 hynylidene fluoride, etc. are preferred.

The metal vapor deposited film formed as described above and the large dielectric substrate treated with discharge treatment 11E@ are treated by applying heat and pressure using a press roll or press plate, etc.
The adhesive is bonded without using an adhesive so as to have a uniform adhesive surface with a predetermined OII bond strength and longitudinal strength.

Here, the temperature condition and the pressure condition have an inversely proportional relationship KTo with respect to the adhesion Kr1A of ll1l and 2nd view. That is, in order to provide the same adhesive strength, 14%/-+ pressure of K is required at low temperature, whereas low pressure is required at high temperature.

Therefore, the stiffness is appropriately selected depending on the required adhesive strength 1'.

After adhesion, the carrier substrate can be immediately peeled off.

Below, please see attachment 111111 for an example of how to improve your luck.

As shown in Figure 1,
Next, a vapor-deposited metal film is preliminarily formed on one surface of the smooth plastic film and the lume OII-bearing substrate by an appropriate vapor deposition method.
o*am and the above: IO treated plastic film ^ are joined by press roll OK. Type of this plastic film for wIII: =t
The metal film adheres to the surface of the plastic film of the electric body by appropriately adjusting the press roll DO heating condition and pressure conditions according to the treatment equipment and metal type 0. ★In addition, the surface of the press roll in this case must have a high degree of smoothness and must not give any harshness to the film. Transfer can be performed in a short time because it can be done without any additional steps.

As mentioned above, the required adhesive strength is determined by the strength of the electrical corona discharge treatment and the pressure and temperature during the press roll.
I'll give you something.

Hereinafter, the present invention will be specifically explained by way of non-limiting examples.
