Abstract
The invention provides potting wax for a metailized film capacitor. The potting wax for a metailized film capacitor comprises: 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 sulphur, 10 to 15 parts of mica powder and 10 to 15 parts of attapulgite. The potting wax for a metailized film capacitor has good toughness and plasticity, excellent electrical properties and suitable kinematic viscosity, and is convenient to fill gaps of a metailized film capacitor.
Description
Technical field
The present invention relates to electrical condenser Embedding Material field, be specifically related to a kind of anti-metallized 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.
Embodiment
The petroleum wax of using among all embodiment, dropping point are all in 70-80 ℃ of scope.
Embodiment 1:
A kind of metallized membrane capacitance embedding wax is made up of following component, and the weight part of each component is:
Embodiment 2:
A kind of metallized membrane capacitance embedding wax is made up of following component, and the weight part of each component is:
Embodiment 3:
A kind of metallized membrane capacitance embedding wax is made up of following component, and the weight part of each component is:
More than the preparation method of each embodiment do, under 100 ℃～110 ℃ temperature, various raw materials mix are melt into uniform liquid, moulding after filtering gets final product.
The experimental data such as the following table of the obtained embedding wax of each embodiment:
Embedding wax melt drop temperature of the present invention is all higher, has good toughness plasticity ability, has good electrical property, and kinematic viscosity is suitable, explains that embedding wax liquid flow performance of the present invention is better, filler metal membrane capacitance gap when being convenient to embedding.
