Problems solved by technology

[0002] Film capacitors use metal foil as an electrode, which is stacked with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and wound into a cylindrical capacitor; in all Among the plastic film capacitors, the characteristics of polypropylene (PP) capacitors and polystyrene (PS) capacitors are the most significant. Of course, the price of these two capacitors is also relatively high. The quality of the capacitor film directly affects the service life and product performance of the capacitor. The demand for films is large and there are many types. It is difficult to meet the requirements of the market by using a single raw material to produce films, but each raw material has its own shortcomings, so the produced films are difficult to meet the needs of various situations

Abstract

The invention relates to the technical field of capacitors, and discloses a high-performance capacitor film. The high-performance capacitor film comprises, by weight, 45-60 parts of polypropylene resin, 5-12 parts of low-density polyethylene, 5-10 parts of organic silicon rubber, 1-4 parts of polyethylene wax, 5-10 parts of antioxidants, 1-5 parts of anti-blocking agents, 3-7 parts of antistatic agents and 1-3 parts of white oil. The polypropylene resin is adopted as a main material, the low-density polyethylene and the organic silicon rubber are added, and the capacitor film is prepared through multiple auxiliary material addition agents jointly in mixing extrusion, film blowing sizing and cutting modes. The high-performance capacitor film has stable physical performance, excellent mechanical strength and excellent electrical insulation performance, and is light, small in loss, high in voltage-resistant breakdown field strength and high in heat resistance. The preparation method is simple, raw materials are easy to obtain, and cost is low.
