In order to realize object of the present invention, the present invention passes through following scheme implementation:
The capacitor metalized film of a kind of composite polyethylene, is made up of the raw material of following weight part: Low Density Polyethylene 200, metallocene linear-low density polyethylene 20-23, '-diphenylmethane diisocyanate 1-2, isobornyl acrylate 4-5, phenyl glycidyl ether 1-2, aromatic urethane 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, calcium zinc stabilizer 2-3, cyanuric acid zinc 1-2,2-ethylhexyl diphenyl phosphate 5-6, linden ashes 1-2, nanometer jade powder 0.3-0.4, phosphorous acid ester 8-10, polyisobutene 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 nanometer jade powder, linden ashes, stirs 10-15 minute, finally adds other composition, and dispersed with stirring is even, cooling, and granulation to obtain final product.
The capacitor metalized film of composite polyethylene of the present invention, made by following concrete steps:
(1) by Low Density Polyethylene, metallocene linear-low density polyethylene, '-diphenylmethane diisocyanate, isobornyl 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; 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, anti-breakdown, fire-retardant, long service life.
