Abstract
The invention provides a sealing paste of a metallized film capacitor, which includes the following components, by weight, 40 to 60 parts of petroleum wax, 10 to 15 parts of polyisobutene, 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 sulphur and 10 to 15 parts of attapulgite. The sealing paste of the metallized film capacitor has good toughness and plasticity, excellent electrical property and appropriate kinematic viscosity, and easily fills gaps of the metallized film capacitor.
Description
Technical field
The present invention relates to electrical condenser Embedding Material field, be specifically related to a kind of anti-sealing paste of metallized film capacitor.
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 sealing paste of metallized film capacitor composition that is applicable to.Embedding composite cream 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:
A kind of sealing paste of metallized film capacitor is characterized in that, is comprised of following component, and the weight part of each component is:
Petroleum wax, dropping point are 70-80 ℃ of 40-60
Polyisobutene 10-15
Vaseline 20-30
Sulphur 10-15
Mica powder 10-15
Vermiculite power 10-15
Attapulgite 10-15.
Described sealing paste of metallized film capacitor is characterized in that, is comprised of following component, and the weight part of each component is:
Petroleum wax 50
Polyisobutene 13
Vaseline 25
Sulphur 13
Mica powder 13
Vermiculite power 13
Attapulgite 13.
The preparation method:
Embedding cream of the present invention is under about 100 ℃～110 ℃ temperature, adds various raw materials and mixed melting and becomes uniform liquid, after filtering moulding.
Beneficial effect of the present invention:
It is good that embedding cream of the present invention has electrical property, moistureproofness, domestic animal, the thermotolerance of flowing and winter hardiness is good, nontoxic, without the burn into inclusion-free, have good use properties.
A) have good insulativity and moistureproofness, guaranteed the stable of metallization film capacitor electrical property;
B) have good liquid fluidity, can added metal membrane capacitance gap;
C) have good heat resistance and winter hardiness, under working temperature, do not trickle, do not shell during cooling;
D) without the burn into inclusion-free, can not produce detrimentally affect to metallization film capacitor;
E) nontoxic, can not cause damage to the healthy of Manufacturing Worker.
