Description
Technical field
The present invention relates to field of capacitor manufacture, particularly capacitor metalized film of a kind of heat-resistant fireproof isotatic polypropylene and preparation method thereof.
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, the high remarkable advantage of fire-retardant, high temperature resistant degree, makes the use range of the electrical condenser that polypropylene film makes more and more wider.
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.

;metallocene linear-low density polyethylene is heated to molten state by preparation method, then, adds nanometer jade powder, linden ashes to stir 10-15 minute, finally adds other composition, and dispersed with stirring is even, cooling, and granulation to obtain final product.
The capacitor metalized film of heat-resistant fireproof isotatic polypropylene of the present invention, made by following concrete steps:
(1) by isotatic polypropylene, ethoxylated alkyl sulfuric acid amine, tea oil, HMPA, tetramethylolmethane, the melting of ethylhexyl dihydrogen phosphate Hybrid Heating, 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 uneven thickness, yield rate is higher, and cost is lower, the at high temperature low and stable performance of percent thermal shrinkage, and flame retardant resistance preferably.
