Abstract

The invention discloses a high-temperature resisting anti-oxidation metallized film which is characterized by being prepared from the following raw materials in parts by weight: 200 parts of isotatic polypropylene, 12-14 parts of polylactic acid, 3-4 parts of tung oil, 1-2 parts of sodium silicate, 1-2 parts of tetrabutyl ammonium bromide, 1-2 parts of yttrium oxide, 2-3 parts of trichlorine ethyl phosphate, 4-5 parts of ester gum, 1-2 parts of turpentine, 4-5 parts of polyisobutene and 5-6 parts of addtivie. The metallized film is simple in machining process, and moreover the film capacitor made of the metallized film is small in contact resistance, small in size and therefore good in product characteristic; a polypropylene capacitor film made of the metallized film has the characteristics of low thermal shrinkage rate and stable property, namely, good high-temperature stability; due to adoption of corona treatment, the pressure resistance of the film is improved, breakdown is prevented, and the service life is long.

Description

technical field [0001] The invention relates to the field of capacitor manufacturing, in particular to a high-temperature-resistant and oxidation-resistant metallized film and its preparation. Background technique [0002] Biaxially oriented polypropylene film for capacitors has high mechanical and electrical properties. Compared with capacitors made of ordinary films, capacitors made of polypropylene films have low thermal shrinkage, stable performance, high temperature resistance, High voltage resistance, breakdown prevention and other significant advantages make capacitors made of polypropylene film more and more widely used. [0003] The existing polypropylene capacitor film has a relatively large shrinkage rate and poor temperature resistance. As the working time of the capacitor wound by this film increases, the internal temperature rises rapidly, resulting in a sharp decline in the stability of the capacitor. It even causes the capacitor to fail, which brings serious...
