Description
Technical field
The present invention relates to field of capacitor manufacture, particularly Low Density Polyethylene modified metal film and preparation method thereof for a kind of electrical condenser.
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 electrical condenser Low Density Polyethylene modified metal film and preparation method thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
Low Density Polyethylene modified metal film for a kind of electrical condenser, is made up of the raw material of following weight part: Low Density Polyethylene 200, Tristearoylglycerol 3-4, xitix 1-2, Trisodium Citrate 3-4, Sodium peroxoborate 1-2, Sodium Fluoride 1-2, methylene-succinic acid 2-3, epoxy acrylate 2-3, 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, silane resin acceptor kh-550 1-2
,2,6-ditertbutylparacresol 1-2, linden ashes 1-2, Radix Angelicae Sinensis oil 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.
Low Density Polyethylene modified metal film for electrical condenser of the present invention, made by following concrete steps:
(1) by Low Density Polyethylene, Tristearoylglycerol, methylene-succinic acid, epoxy acrylate 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; Adopt corona treatment, improved the compressive strength of film, prevent from puncturing, and this invention has good current-carrying, anti-shoving and resistance to pulse ability, long service life.
