Abstract
The invention relates to a porcelain material formula of a porcelain shell used for capacitors. Existing capacitor porcelain shell formulas have raw materials characterized by rare content and inconvenient access, thus leading to a high formula cost. The capacitor porcelain shell of the invention is composed of the following raw materials by weight: 9.2-10.2 parts of Houxi porcelain clays, 6.0-7.5 parts of Guangdong white mud, 4.2-4.8 parts of pyrophyllite, 3.2-3.7 parts of Zuoyun soil, 1.5-1.8 parts of bauxite powder, 1.0-1.3 parts of Ninghai soil, and 1.0 part of feldspar powder. Among the various raw materials needed in the invention, 30% of the raw materials are taken from local porcelain clays of Jiangsu and Zhejiang, 15% of the raw materials are local paraffin, a small part comes from the clays of Ninghai, Zhejiang province, and the remaining raw materials are common clays, alumina and feldspar, etc. Therefore, the various raw materials have the advantages of abundant storage, convenient access, and low costs, and can be used to produce porcelain shell products with performances meeting and being superior to corresponding indexes.
Description
Technical field
The present invention relates to the ceramic material prescription of a kind of electrical condenser with insulator.
Background technology
The prescription of existing porcelain shell for capacitor mainly is made up of the clay of high plasticities such as bauxitic clay, Feldspar Powder, sericite class china clay, Zuoyun soil, high-performance ball clay, ZhangZhou black mud; Wherein sericite china clay mineral reserve class is mainly concentrated ground such as western part, Jiangxi, Hunan; Clay class mineral are also most in the north or south China; Because the distribution of main prescription ground disperses, and material content rare, take inconvenience, cause formulation cost higher.
Summary of the invention
The present invention is directed to the defective that prior art exists; A kind of prescription of porcelain shell for capacitor is provided; Each raw material drawing is convenient, and cost is lower, and the porcelain shell for capacitor of making satisfies each item machinery and the electrical performance indexes of JB/T 11052-2010 " electrical condenser is with press insert type insulation thimble technical qualification ".
For this reason, the present invention takes following technical scheme: said porcelain shell for capacitor is processed by the feed composition of following weight part:
Consist predominantly of SiO in the china clay of described Houxi

3, SiO wherein
2, Al
2O
3Shared percentage composition is respectively 57%, 24%, 4%.
Said Houxi china clay essential mineral composition is: quartz, illite, kaolin, potassium felspar sand.
Said Ninghai soil essential mineral becomes: kaolin, quartz, a small amount of smectite have good plasticity-and higher ridity.
In each item raw material required for the present invention 30% take from Jiangsu and Zhejiang Provinces one band local china clay, 15% what take is local paraffin, also has few part to be derived from the clay of Ninghai, Zhejiang, surplus stock all is clay, alumina and feldspars etc. of using always.Therefore, that all kinds of raw materials are contained is abundant, take conveniently, cost is lower, and the insulator product performance of making reach and are superior to corresponding index.

The present invention adopts wet moulding, and technical process is following: batching → ball milling → press filt → old → pugging → moulding → drying room drying → kiln burns till → assembles → and detects.
The insulator product that adopts this prescription to produce mainly contains 6 umbrellas, 10 umbrellas, 13 umbrella porcelains shell for capacitor, and is following through detecting its main performance index:
Test through porosity: pressure should be not less than 20Mpa, and pressure and the time product of (h) is not less than 180Mpa.h, and does not have phenomenon of osmosis.
What need particularly point out is; The mode of the foregoing description only limits to describe embodiment; But the present invention is confined to aforesaid way incessantly; And those skilled in the art can modify in not departing from the scope of the present invention in view of the above easily, and therefore scope of the present invention should comprise the disclosed principle and the maximum range of new feature.
