Abstract
The invention discloses a metalized film for a capacitor taking a linear low density polyethylene as a base body. The metalized film is characterized by being prepared from the following raw materials in parts by weight: 200 parts of the linear low density polyethylene, 20-23 parts of EVA (Ethylene Vinyl Acetate), 1-2 parts of zinc stearate, 1-2 parts of aluminum oxide powder, 10-12 parts of straw ash, 2-4 parts of coconut oil diethanoamine condensate, 1-2 parts of malic acid, 1-2 parts of sodium propionate, 1-2 parts of sodium citrate and 5-6 parts of auxiliary agent. The metalized film is simple in processing process and the contact resistance of a thin film capacitor produced by the metalized film is small, so that the property of a product is good. The metalized film has good physical performances and electrical performances and particularly has a high-temperature-resisting property; the auxiliary agent is added so that the barrier property and the gas tightness of the thin film are enhanced; the metalized film has good voltage resistance and impact resistance, and also has the characteristics of high heat sealing strength and good heat sealing performance.
Description
Technical field
The present invention relates to field of capacitor manufacture, particularly a kind of metalized film and preparation method thereof of the electrical condenser take linear low density polyethylene as matrix.
Background technology
Film capacitor is to work as electrode with tinsel, by itself and poly-ethyl ester, and polypropylene, the plastics films such as polystyrene or polycarbonate, from two ends are overlapping, are wound into the electrical condenser of structure cylindraceous; In the middle of all plastics film electric capacity, the characteristic of polypropylene (PP) electric capacity and polystyrene (PS) electric capacity is the most remarkable, certainly the price of these two kinds of electrical condensers is also higher, the film quality of electrical condenser directly affects work-ing life and the product performance of electrical condenser, the demand of capacitor film is large, kind is many, adopt the film of single raw material production to be difficult to adapt to the requirement in market, but every kind of raw material has its weak point, so the film of producing is difficult to meet the demand of various situations.
Summary of the invention
The object of this invention is to provide a kind of metalized film of the electrical condenser take linear low density polyethylene as matrix and preparation method thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
An electrical condenser metalized film take linear low density polyethylene as matrix, is made up of the raw material of following weight part: linear low density polyethylene 200, EVA20-23, Zinic stearas 1-2, aluminum oxide powder 1-2, stalk ashes 10-12, coconut acid diethanolamide 2-4, oxysuccinic acid 1-2, Sodium Propionate 1-2, Trisodium Citrate 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, Union carbide A-162 1-2, ferrocene 1-2, linden ashes 1-2, Vulcanization accelerator TMTD 1-2; Metallocene linear-low density polyethylene is heated to molten state by preparation method, adds other composition, and dispersed with stirring is even, cooling, and granulation to obtain final product.
Electrical condenser metalized film take linear low density polyethylene as matrix of the present invention, made by following concrete steps:
(1) by linear low density polyethylene, EVA, Zinic stearas 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 ℃;
(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, has good physical and electric property, has especially high-temperature stability; Add auxiliary agent, strengthened barrier and the resistance to air loss of film, there is good resistance to pressure and shock-resistance, there is the feature that heat seal strength is high, heat sealability is good simultaneously.
