Abstract
The invention provides a novel metalized film capacitor encapsulation wax, comprising the following components in parts 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 sulphur, 10 to 15 parts of mica powder and 3 to 5 parts of straw ash. The metalized film capacitor encapsulation wax has good ductility, excellent electrical property and appropriate kinematic viscosity, and is convenient to fill clearances of a metalized film capacitor.
Description
Technical field
The present invention relates to electrical condenser Embedding Material field, be specifically related to a kind of novel metal membrane capacitance embedding wax
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 toughness plasticity difference low temperature easy embrittlement in simple commodity in use paraffin or Microcrystalline Wax and defective such as bigger contraction are arranged, and use oils to exist loss big and be easy to seepage, the requirement of the current factory of incompatibility.It all is staple with oils that existing patent is introduced the metallized membrane capacitance embedding material, adopts polybutylenes-korenyl-cottonseed oil mixture embedding, US6,280,659 usefulness vegetables oil embedding electrical condensers like the introduction of JP03035513 patent.
Summary of the invention
To the deficiency of prior art, the invention provides a kind of metallized membrane capacitance embedding wax compsn that is applicable to.Embedding wax compsn of the present invention has toughness plasticity can be good, can not rupture under the low temperature, shrinks not obvious.
The technical scheme that adopts for the present invention of realization above-mentioned purpose is following:
A kind of metallized membrane capacitance embedding wax is characterized in that, is made up of following component, and the weight part of each component is:
Described metallized membrane capacitance embedding wax is characterized in that, is made up of following component, and the weight part of each component is:
Described metallized membrane capacitance embedding wax is characterized in that: the dropping point of described petroleum wax is 70-80 ℃.
The preparation method:
Embedding wax of the present invention is under about 100 ℃～110 ℃ temperature, adds various raw materials and mixed melting and becomes uniform liquid, moulding after filtering.
Beneficial effect of the present invention:
It is good that embedding wax of the present invention has electrical property, and moistureproofness, flow domestic animal, thermotolerance and good, nontoxic, the no burn into inclusion-free of winter hardiness 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) no 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.
