Technical field
The present invention relates to field of capacitor manufacture, particularly capacitor metalized film of composite polyethylene of a kind of low cost of manufacture and preparation method thereof.
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 capacitor metalized film of composite polyethylene of a kind of low cost of manufacture and preparation method thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
The capacitor metalized film of composite polyethylene of low cost of manufacture, is made up of the raw material of following weight part: Low Density Polyethylene 200, ferrous pyrophosphate 1-2, aluminate coupling agent 1-2, N hydroxymethyl acrylamide 1-2, caprylin 2-3, propylene glycol methyl ether acetate 4-6, dibasic lead phosphite 1-2, Silane coupling agent KH550 1-2, Viscoat 295 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, 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.
The capacitor metalized film of composite polyethylene of low cost of manufacture of the present invention, made by following concrete steps:
(1) by Low Density Polyethylene, ferrous pyrophosphate, aluminate coupling agent, N hydroxymethyl acrylamide, caprylin 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; By filtering, remove the impurity in raw material, make material performance good, reduce the condemnation factor of film, be difficult for breaking; Adopt corona treatment, improved the compressive strength of film, prevent from puncturing, reduced production cost, long service life.
