Abstract
The invention provides a metallized-film capacitor sealing agent composed of components of, by weight: 40 to 60 parts of petroleum wax, 10 to 15 parts of polyisobutylene, 20 to 30 parts of vaseline, 10 to 15 parts of mica powder, 10 to 15 parts of vermiculite powder, 10 to 15 parts of sulfur, 3 to 5 parts of straw ash, and 10 to 15 parts of attapulgite. The metallized-film capacitor sealing agent provided by the invention has good toughness and plasticity, excellent electrical properties, and appropriate kinematical viscosity. With the sealing agent, gaps between metallized-film capacitors can be conveniently filled.
Description
Technical field
The present invention relates to electrical condenser Embedding Material field, be specifically related to a kind of anti-metallized-film capacitor sealing agent.
Background technology
During metallization film capacitor was produced, the hole between main medium and pole plate and the main medium normally carried out embedding with a kind of material, with raising electrical capacity and insulating property, and improved shelf depreciation and resistance toheat.There are under the poor low temperature of toughness plasticity easily embrittlement in simple commodity in use paraffin or Microcrystalline Wax and the defective such as larger contraction are arranged, and use oils to exist loss large and be easy to seepage, are not suitable with the requirement of current factory.Existing patent Introduction metallized membrane capacitance embedding material adopts polybutene-alkylbenzene-cottonseed oil mixture embedding all take oils as main component such as the JP03035513 patent Introduction, and US 6,280,659 usefulness vegetables oil embedding electrical condensers.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of metallized-film capacitor sealing agent composition that is applicable to.Embedding agent composition of the present invention has toughness plasticity can be good, can not rupture under the low temperature, shrinks not obvious.
The technical solution used in the present invention is as follows for achieving the above object:
