Abstract
The invention discloses an oxidation-resistant breakdown-resistant capacitor metalized film. The oxidation-resistant breakdown-resistant capacitor metalized film is characterized in that the oxidation-resistant breakdown-resistant capacitor metalized film is manufactured from the following raw materials of, by weight, two hundred parts of isotatic polypropylene, one to two parts of phenylalanine, three to four parts of polyvinyl butyral, one to two parts of titanate coupling agents TMC-TTS, one to two parts of benzyl dimethyl phenyl polyoxyethylene ether, two to three parts of butoxy triethyl phosphate, one to two parts of nonyl phenol, one to two parts of TAIC and five to six parts of auxiliaries. According to the oxidation-resistant breakdown-resistant capacitor metalized film, impurities in the raw materials are removed through filtering to enable the raw materials to be good in performance, therefore, the rejection rate of the film is lowered and breakage is not prone to occurring; corona treatment is adopted, so that the withstand voltage strength of the film is enhanced and breakdown is prevented; a vacuum evaporation metalized film body is adopted, so that the oxidation resistance is improved. Moreover, the oxidation-resistant breakdown-resistant capacitor metalized film further has good current carrying, flashy flow resistant and pulse resistant capacity and is long in service life.
Description
Technical field
The present invention relates to field of capacitor manufacture, particularly capacitor metalized film and preparation method thereof is worn in a kind of anti-oxidant resistance.
Background technology
Capacitor has higher mechanical performance and electric property with bidirectional stretching polypropylene film, compared with the capacitor making with plain edition film, the capacitor making with polypropylene film is low with its percent thermal shrinkage, stable performance, high temperature resistant, high pressure resistant, the remarkable advantage such as prevent from puncturing, make the scope of application of the capacitor that polypropylene film makes more and more wider.
Capacitor core is the heart of capacitor, and therefore capacitor manufacture fuse material must have resistance to high frequency, resistance to height
Temperature, can bear a kind of macromolecule polypropylene film of heavy current impact and make medium, and guarantee complete machine is worked steadily in the long term.In prior art, most of medium adopting is polyester or polypropylene light film, and electrode is aluminium foil, also has a small amount of product to use polypropylene metallization vapor-deposited film.Because market complete machine is all intended for ultrathin type, microminiature development, although paper tinsel film composite material current-carrying dielectric capacity is strong, but being volume, its shortcoming is unfavorable for greatly assembling complete machine use, to be that polypropylene screen and aluminium foil are compound the control of technique difficulty or ease such as roll to another shortcoming, particularly in coiling fuse process because of the difference of both material hard toughness, can cause between film paper tinsel and occur gap, to making, material thermal contraction when shaping is abundant not, cause being easily electrically shocked and wearing between film paper tinsel, scrappage is higher, has caused cost waste.
