Description
Technical field
The present invention relates to field of capacitor manufacture, particularly metallized film and preparation method thereof for a kind of electrical condenser of good combination property.
Background technology
Electrical condenser has higher mechanical property and electric property with BiOriented Polypropylene Films, compared with the electrical condenser making with coventional type film, the electrical condenser 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 use range of the electrical condenser that polypropylene film makes more and more wider.
Existing polypropylene capactive film, shrinking percentage is relatively bigger than normal, temperature tolerance is poor, with the electrical condenser that the forms lengthening along with its working hour of reeling of this film, its internal temperature rise is very fast, cause the stability of electrical condenser sharply to decline, even cause electrical condenser to lose efficacy, bring serious potential safety hazard to electrical equipment complete machine or electrical network.Therefore the heat resistance as dielectric polypropylene film is had higher requirement.Meanwhile, because electrical means is to the development of miniaturization and densification direction, the indexs such as the volume to electrical condenser have proposed requirements at the higher level.
Capacitor core is the heart of electrical condenser, and therefore electrical condenser 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, mini-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 in the time shaping is abundant not, cause being easily electrically shocked and wearing between film paper tinsel, condemnation factor is higher, has caused cost waste.The raw material impurity of selecting while preparing capacitor metalized film because of prior art is again more, so can cause the capacitor metalized film properties produced poor, and because prior art while preparing capacitor metalized film longitudinally and the various parameter settings of cross directional stretch operation bad, so probably cause membrane fracture, rupture of membranes impact is normal produces.
Summary of the invention

The electrical condenser metallized film of good combination property of the present invention, made by following concrete steps:
(1) by isotatic polypropylene, silane resin acceptor kh-550, Hydroxyethyl acrylate, urethane acrylate heating and melting, add again auxiliary agent and all the other remaining components fully to stir, send into forcing machine melting, filtration, and then by forcing machine extruding sheet melt, filter >1200 order, the temperature of described forcing machine is 220-260 DEG C;
(2) the sheet melt of step (1) being made makes slab after by sharp cooling roll and air raining chamber cooling and shaping, carries out successively longitudinal stretching, cross directional stretch, alligatoring face corona treatment;
(3) rolling, ageing treatment, ageing treatment for the second time for the first time;
(4) vacuum-evaporation metalized film, alligatoring face forms metal layer.
Beneficial effect of the present invention is: the present invention, by filtering, removes the impurity in raw material, makes material performance good, has reduced the condemnation factor of film, is difficult for breaking; Adopt corona treatment, improved the compressive strength of film, prevent from puncturing, and complete processing is simple, and little with the film capacitor contact resistance of its making, thus make product performance good.
