Abstract
The invention discloses the capacitor metallized film of a kind of high-temperature stable, it is characterized in that, be prepared by the raw materials in: isotactic polypropylene 200, Ethylene-butyl acrylate-ethylene oxidic ester terpolymer 12-14, polylactic acid 4-5, poly-vinyl butyrate 2-3, captax 1-2, m-xylene diamine 2-3, auxiliary agent 5-6；Polypropylene capactive film thickness prepared by the present invention is uniform, and yield rate is high, low cost, has that at high temperature percent thermal shrinkage is low and the preferable feature of stable performance, i.e. high-temperature stability, and thin film capacitor contact resistance is little, so that product attribute is good.
Description
Technical field
The present invention relates to field of capacitor manufacture, capacitor metallized film of a kind of high-temperature stable and preparation method thereof.
Background technology
Capacitor bidirectional stretching polypropylene film has higher mechanical performance and electric property, compared with the capacitor that plain edition thin film prepares, with polypropylene film prepare capacitor is low with its percent thermal shrinkage, stable performance, the high remarkable advantage of high temperature resistant degree so that the range of the capacitor that polypropylene film prepares is more and more wider.
Capacitor core is the heart of capacitor, and therefore capacitor manufacture fuse material must have high frequency tolerant, resistance to height
Temperature, a kind of macromolecule polypropylene film that can bear heavy current impact makees medium, and guarantee complete machine works steadily in the long term.The medium that in prior art, major part uses is polyester or polypropylene light film, and electrode is aluminium foil, also has a small amount of product to use polypropylene metallization evaporation film.Owing to market complete machine is all intended for ultrathin type, microminiature develops, although paper tinsel film composite material current-carrying dielectric capacity is strong, but its shortcoming is volume is unfavorable for that greatly assembling complete machine uses, and further drawback is that the polypropylene screen technique difficulty or ease such as roll compound with aluminium foil control, particularly because of the difference of both material hard toughness during coiling fuse, can cause and gap occur between film paper tinsel, to making, material thermal contraction when sizing is abundant not, causes easily being electrically shocked between film paper tinsel wearing, scrappage is higher, causes cost waste.Again because the raw material impurity selected when prior art prepares capacitor metalized film is more, so the capacitor metalized film properties produced can be caused poor, and because the various parameters setting of longitudinal direction and cross directional stretch operation is bad when prior art prepares capacitor metalized film, so being likely to result in membrane fracture, rupture of membranes impact is normal to be produced.
Summary of the invention
Capacitor metallized film that it is an object of the invention to provide a kind of high-temperature stable and preparation method thereof.
In order to realize the purpose of the present invention, the present invention is implemented by below scheme:
The capacitor metallized film of a kind of high-temperature stable, is prepared by the raw materials in: isotactic polypropylene 200, Ethylene-butyl acrylate-ethylene oxidic ester terpolymer 12-14, polylactic acid 4-5, poly-vinyl butyrate 2-3, captax 1-2, m-xylene diamine 2-3, auxiliary agent 5-6；
Described auxiliary agent is prepared by the raw materials in: metallocene linear-low density polyethylene 12-15,2,6-ditertbutylparacresol 1-2, alcohol ester 12 1-2, basswood ashes 1-2, cross-linking agent TAC1-2, morpholine 1-2, nanometer jade powder 0.3-0.4, tea polyphenols 1-2, dilauryl thiodipropionate 2-3, Flos Rosae Rugosae quintessence oil 0.1-0.2；Preparation method is that metallocene linear-low density polyethylene is heated to molten condition, then, adds nanometer jade powder, tea polyphenols stirring 10-15 minute, is eventually adding other composition, and dispersed with stirring is uniform, cooling, and pelletize to obtain final product.
The capacitor metallized film of high-temperature stable of the present invention, is made up of step in detail below:
(1) isotactic polypropylene, polytrimethylene terephthalate, polymethylpentene, PC reclaimed materials Hybrid Heating are melted, add auxiliary agent and remaining residual components is sufficiently stirred for, send into extruder to melt, filter, the most again by extruder extruding sheet melt, filter 1200 mesh, the temperature of described extruder is 220-250 DEG C；
(2) lamellar melt step (1) made is by preparing slab after sharp cooling roll and Airshower chamber cooling and shaping, carries out longitudinal stretching, cross directional stretch, roughening face sided corona treatment successively；
(3) rolling, for the first time Ageing Treatment, for the second time Ageing Treatment；
(4) vacuum evaporation metalized film, roughening face forms metal layer.
Processing technique of the present invention is simple, and little with its thin film capacitor contact resistance made, so that product attribute is good.
The invention have the benefit that polypropylene capactive film thickness prepared by the present invention is uniform, yield rate is high, low cost, have that at high temperature percent thermal shrinkage is low and stable performance, the i.e. preferable feature of high-temperature stability, and thin film capacitor contact resistance is little, so that product attribute is good.
