Description
Technical field
The present invention relates to thin film capacitor technical field, particularly relate to a kind of high-power metallic thin film capacitor and preparation method thereof.
Background technology
Thin film capacitor is to work as electrode with metal forming, by itself and poly-ethyl ester, polypropylene, the plastic sheeting such as polystyrene or Merlon, after the overlap of two ends, is wound into the capacitor of the structure of cylindrical shape；In the middle of all of plastic sheeting electric capacity, the characteristic of polypropylene (PP) electric capacity and polystyrene (PS) electric capacity is the most notable, the price of certain both capacitors is also higher, the film quality of capacitor directly affects service life and the properties of product of capacitor, the demand of capacitor film is big, kind is many, the thin film adopting single raw material production is difficult to adapt to the requirement in market, but every kind of raw material has its weak point, so the thin film produced is difficult to meet the demand of various situation.
Capacitor bidirectional stretching polypropylene film has higher mechanical performance and electric property, compared with the capacitor that plain edition thin film prepares, with polypropylene film prepare capacitor is low with its percent thermal shrinkage, stable performance, high temperature resistant, high pressure resistant, prevent remarkable advantages such as puncturing so that the use scope of the capacitor that polypropylene film prepares is more and more wider.
Summary of the invention
The present invention proposes a kind of high-power metallic thin film capacitor and preparation method thereof, gained high-power metallic thin film capacitor volume is little, pressure height, nonpolarity, reverse impulse voltage can be born for a long time, high effective current and high peak current can be born, inductance value is little, and Surge handling capability is strong, dielectric loss is little, long service life.
A kind of high-power metallic thin film capacitor that the present invention proposes, the raw material of its plastic sheeting includes by weight: polypropylene 45～55 parts, alkyd resin 25～30 parts, 30～35 parts of phenolic resin, chlorosulfonated polyethylene 15～18 parts, methyl vinyl silicone rubber 9～12 parts, titanium diboride 8～11 parts, titanium dioxide 24～27 parts, 5～8 parts of barium sulfate, antimonous bromide 3～6 parts, glass fibre 2～5 parts, lignin 12～15 parts, calcium titanium fiber 6～8 parts, silane coupler KH5703～4 part, 2, 5-dimethyl-2, 5-pair-(t-butyl peroxy) hexane 1.3～1.6 parts, 3～4 parts of sulfur, potassium sorbate 1.1～1.3 parts, N-cyclohexyl-2-[4-morpholinodithio sulfenamide 1.2～1.8 parts, diphenylguanidine 0.8～1.3 part, magnesium oxide 4～5 parts, molybdenum bisuphide 5～7 parts, ethyl hexyl ester of epoxidized soybean oil 7～10 parts, calcium zinc stabilizer 2～4 parts, dicyandiamide 2～3 parts, antioxidant D FC-341～2 part, antioxidant 616 2～3 parts.
