Abstract

The invention discloses a capacitor thin film with high performance, and belongs to the technical field of electronic components. The capacitor thin film with high performance is specifically prepared from, modified polyethylene terephathalate, polyimide, modified diatomite, bisphenol-A epoxy resin, nanometer silicon dioxide, nanometer boron fiber, dimethyl formamide, triallyl cyanurate, polystyrene, diethylene glycol dimethyl ether, antioxidant, heat stabilizer, and ultraviolet light absorber. In actual use, the thin film with high performance shows an excellent stretch-proof property and a high-temperature resistant property; meanwhile, the thin film and a clad layer are adhered and combined tightly and stably mutually, thus residual interior air is reduced, probability of generation of air breakdown is further lowered, and finally the service life of the capacitor can be prolonged by 30% or above.

Description

technical field [0001] The invention belongs to the technical field of electronic components, and in particular relates to a thin film for capacitors with excellent performance. Background technique [0002] Film capacitors are widely used in analog circuits due to their excellent characteristics such as non-polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and low dielectric loss. Film capacitors use metal foil as an electrode, and it is laminated with plastic base films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wound into a cylindrical capacitor; The thickness of the foil is thicker. With the development of more and more refined electrical components, it is replaced by a metal coating, that is, a layer of metal film is coated on the original film surface, which can significantly improve the size of the components. [0003] At present, the common metallized films used in th...
