Abstract
The invention discloses a polypropylene metallized film with good mechanical strength for a capacitor. The polypropylene metallized film is characterized by being prepared from the following raw materials in parts by weight: 200 parts of isotactic polypropylene, 4-5 parts of dibutyl phthalate, 1-2 parts of calcium stearate, 2-3 parts of menthyl acetate, 1-2 parts of lauryl-alcohol polyoxyethylene ether, 1-2 parts of mono-butyl tin oxide, 1-2 parts of cross-linking agent TAC and 5-6 parts of auxiliaries. According to the polypropylene metallized film, the processing process is simple, and the contact resistance of a thin-film capacitor manufactured by using the polypropylene metallized film is low, so that the characteristics of the product are good; and the polypropylene metallized film has excellent physical and electrical properties, particularly has high-temperature resistant characteristic, is high-pressure resistant and breakdown-resistant and is high in mechanical strength and long in service life.
Description
Technical field
The present invention relates to field of capacitor manufacture, particularly the good polypropylene metallized film and preparation method thereof for electrical condenser of a kind of physical strength.
Background technology
Electrical condenser has higher mechanical property and electric property with BiOriented Polypropylene Films, compare with the electrical condenser that coventional type film makes, 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.
Capacitor core is the heart of electrical condenser, so 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, another shortcoming is that the compound technique difficulty or ease such as roll of polypropylene screen and aluminium foil are controlled, 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, 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 object of this invention is to provide the good electrical condenser of a kind of physical strength polypropylene metallized film and preparation method thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
The electrical condenser polypropylene metallized film that physical strength is good, is made by the raw material of following weight part: isotatic polypropylene 200, dibutyl phthalate 4-5, calcium stearate 1-2, menthyl acetate 2-3, ethoxylated dodecyl alcohol 1-2, Mono-n-butyltin 1-2, linking agent TAC1-2, auxiliary agent 5-6;
Described auxiliary agent is made by the raw material of following weight part: metallocene linear-low density polyethylene 12-15, Sodium Benzoate 1-2, Radix Angelicae Sinensis oil 1-2, polyisobutene 3-4, Silane coupling agent KH550 1-2, linden ashes 1-2, Sodium Selenite 1-2, nanometer jade powder 0.3-0.4, Flos Rosae Rugosae quintessence oil 0.1-0.2
;preparation method is heated to molten state by metallocene linear-low density polyethylene, 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 obtains.
The electrical condenser polypropylene metallized film that physical strength of the present invention is good, by following concrete steps, made:
(1) by isotatic polypropylene, dibutyl phthalate, calcium stearate, the melting of menthyl acetate 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 ℃;
(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.
Complete processing of the present invention is simple, and little with the film capacitor contact resistance of its making, thereby makes product performance good, and the present invention has good physical and electric property, there is especially high-temperature stability, physical strength is large, high pressure resistant, resistance is worn, long service life.
