Abstract
The invention discloses a high-temperature resistant ultrathin isotactic polypropylene metallized film for a capacitor, which is characterized by being prepared from the following raw materials in parts by weight: 200 parts of isotactic polypropylene, 1-2 parts of aluminum hydroxide, 2-3 parts of polyethylene amide, 1-2 parts of N-hydroxymethyl acrylamide, 1-2 parts of ethylene glycol, 2-3 parts of dicyclopentadiene, 1-2 parts of polyepoxysuccinic acid, 2-3 parts of dodecanoic acid, 1-2 parts of polyester acrylate and 5-6 parts of auxiliary. In the invention, the processing technology is simple, and the prepared film capacitor has low contact resistance so that the product features are good; the film disclosed by the invention is uniform in thickness and is not separated easily while the cost is low; the prepared capacitor is relatively small in volume and has the characteristics of low heat shrinkage and stable performance at high temperature, namely, relatively good high-temperature stability.
Description
Technical field
The present invention relates to field of capacitor manufacture, particularly high temperature resistant ultrathin isotatic polypropylene metalized film and preparation method thereof for a kind of electrical condenser.
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.
Summary of the invention
The object of this invention is to provide a kind of electrical condenser high temperature resistant ultrathin isotatic polypropylene metalized film and preparation method thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
High temperature resistant ultrathin isotatic polypropylene metalized film for a kind of electrical condenser, is made up of the raw material of following weight part: isotatic polypropylene 200, aluminium hydroxide 1-2, polyvinyl lactam 2-3, N hydroxymethyl acrylamide 1-2, ethylene glycol 1-2, dicyclopentadiene 2-3, poly-epoxy succinic acid 1-2, laurostearic acid 2-3, polyester acrylate 1-2, auxiliary agent 5-6;
Described auxiliary agent is made up of the raw material of following weight part: metallocene linear-low density polyethylene 12-15, acetyl triethyl citrate 14-18, propionate 3-4, linden ashes 1-2, linking agent TAC1-2,2-ethylhexyl diphenyl phosphate 5-6, polyvinyl alcohol 2-3, Flos Rosae Rugosae quintessence oil 0.1-0.2; Metallocene linear-low density polyethylene is heated to molten state by preparation method, then, adds polyvinyl alcohol, linden ashes to stir 10-15 minute, finally adds other composition, and dispersed with stirring is even, cooling, and granulation to obtain final product.
High temperature resistant ultrathin isotatic polypropylene metalized film for electrical condenser of the present invention, made by following concrete steps:
(1) by isotatic polypropylene, aluminium hydroxide, polyvinyl lactam, N hydroxymethyl acrylamide, the melting of ethylene glycol 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; Film thickness of the present invention is even, is not easy to throw off, and cost is low, and the small volume of the electrical condenser of making has at high temperature percent thermal shrinkage low and stable performance, the i.e. good feature of high-temperature stability.
