下に制限されている。2. Description of the Related Art In general, a vapor-deposited metallized film capacitor is a vapor-deposited metallized film obtained by polymerizing two sheets of a first vapor-deposited metallized film and a second vapor-deposited metallized film. It is formed by winding, providing a lead-out electrode metal sprayed layer on the winding end face, and further inserting this into a plastic case. In the production of the vapor-deposited metallized film capacitor, there are problems that the vapor-deposited metallized film is wrinkled or foreign matter is mixed into the vapor-deposited metalized film at the time of winding, and the film is scratched. All of these problems deteriorate the quality of the capacitor. For example, when wrinkles enter the film, air containing water is retained in that part, which deteriorates the electrical characteristics of that part.
It also causes local corona discharge. Causes of this wrinkle are subtle fluctuations in the rotation speed and tension during winding, machine vibration, etc., and countermeasures against it are required. Further, polypropylene film has excellent dielectric characteristics for capacitors and is particularly excellent in loss and temperature characteristics, but has a drawback that it has low heat resistance and the maximum operating temperature is limited to 90 ° C or lower.

た。[Means and Actions for Solving the Problems] Various means such as auto-tension and line speed have been devised as means for achieving good winding of the vapor-deposited metallized film during the production of the film capacitor. But it's not perfect yet. In order to solve this point, the present inventor has excellent electrical characteristics and has a high surface hardness of the film as a film that eliminates problems during winding.
As a result of investigating the use of films with high Young's modulus, low elongation, easy slippage, and high blocking degree, and examining various plastic films, a high-rigidity polypropylene film with significantly increased crystallinity and stereoregularity was found. We have found that it is suitable for film capacitors.
The inventors of the present invention have further advanced the study, and by using a vapor-deposited metallized film having a high degree of crystallinity and high stereoregularity and a high-rigidity polypropylene film vapor-deposited with a metal, vapor deposition with very few wrinkles and scratches is obtained. We succeeded in obtaining a roll of metallized film. It was also found that this is a capacitor having excellent characteristics such as a dielectric constant as a capacitor and capable of withstanding a heat resistant temperature of 100 ° C. or higher.

A vapor-deposited metallized film capacitor characterized by comprising a high-rigidity vapor-deposited metallized film obtained by vapor-depositing a metal on a high-rigidity polypropylene film having a high degree of crystallinity and good stereoregularity of up to 260 kg / mm 2. is there. The above-mentioned highly rigid polypropylene film having extremely high crystallinity and stereoregularity is known (for example, JP-A-58-10490).
No. 7, JP-A-2-206605), for example, a highly active and high-performance catalyst prepared by pretreating titanium trichloride and an organoaluminum compound with an electron donor such as an aromatic carboxylic acid ester. A polypropylene resin having a heat distortion temperature of 120 to 140 ° C. obtained by polymerizing propylene used is formed into a film by a tenter stretching method or the like. This film has a Young's modulus of about 220 to 260 kg / mm 2 , high crystallinity (about 70%), and good stereoregularity (about 90%). Therefore, this polypropylene film has rigidity, melting point, heat distortion resistance, hardness, and creep resistance, which are higher than those of conventional polypropylene films.
It is excellent in chemical resistance.

きる。The high-strength polypropylene film according to the present invention has a large Young's modulus, a small tensile elongation at break, a small sliding friction coefficient and a large blocking degree. These physical properties can significantly reduce the problems at the time of winding the vapor-deposited metallized film produced using this as a raw material, and the film capacitor needs to change the winding strength depending on its shape. Since the film has a high Young's modulus and a small coefficient of friction, the strength of winding the element can be set relatively easily. Furthermore, this high-rigidity polypropylene film has a high heat distortion temperature,
Since the heat shrinkage rate is small, the maximum operating temperature of the film capacitor made of this can be improved up to 105 ° C.

In the case of the example of the present invention, the decrease in the capacitance is within the criterion up to about 100 hours even under the condition that the applied voltage is increased to 500 V, whereas in the comparative example, within a few hours under the same applied voltage. It turns out that it becomes something other than the criterion.
Further, under the condition that the applied voltage is 400 V, the capacitance of the comparative example is out of the criterion in a few hundred hours, whereas the product of the present invention has an electrostatic capacitance of 10,000 hours or more. There is no decrease in capacity and all meet the criteria,
It can be confirmed that the product of the present invention is extremely durable.
