Abstract
The invention discloses a novel high-strength ceramic insulator which is prepared from the following raw materials in parts by weight: 2-5 parts of smolmitza, 35-45 parts of alumina, 5-10 parts of Zhangcun soil, 8-20 parts of Jingyang soil, 6-15 parts of Zuoyun soil, 7-15 parts of Qingcaoling, 11-20 parts of white glue slime, 5-15 parts of feldspar, 1-5 parts of Ninghai soil and 1-5 parts of Xinhui soil. The ceramic insulator disclosed by the invention has the advantages of favorable mechanical properties and low production cost, and can easily implement technical control. All the raw materials are common ceramic mineral raw materials; and the adoption of the Jingyang soil shortens the ball milling time, lowers the cost and improves the technical properties. Different mineral types of clay are reasonably matched, so that the material has favorable technical properties, especially firing property, can easily implement technical control, and enhances the qualification rate of the ceramics.
Description
Technical field
The invention belongs to the electroceramics technical field,, be specifically related to a kind of novel high-strength porcelain insulator prescription and preparation method thereof.
Background technology
The electroceramics blank is meant the mixture that clay raw material and flux property raw material and other raw materials (quartz, high aluminium material or other raw mineral materialss) are formed by a certain percentage, can supply base to use pug through levigate with being mixed into, and the pug that this base is used just abbreviates blank as.
Must guarantee that when confirming various material rate blank can satisfy desired use characteristics of electric porcelain production process and the physicals requirement of burning till the back porcelain.As long as the use characteristics of blank depends on the quality and the consumption of clay raw material before burning till, the firing process of blank depends primarily on flux raw material.
Physical strength is the most important performance that electric porcelain production is pursued always, because electroporcelain material when having HS, under the condition of equal voltage range, can improve the rate of utilization of material, reduces cost.Traditional porcelain insulator, physical strength are not high, after the glazing to improve electroceramics mechanical, electrical, the thermal property effect is bad, the flexural strength of raising porcelain that especially can not be bigger.
Summary of the invention
For solving the deficiency of prior art, the object of the present invention is to provide a kind of good mechanical property, and the low novel high-strength porcelain insulator of production cost and preparation method thereof.
For achieving the above object, the present invention realizes through following technical scheme: a kind of novel high-strength porcelain insulator comprises by the composition of raw materials of following parts by weight and processes: smolmitza 2-5 part; Alumina 35-45 part, camphor tree village soil 5-10 part, Jingyang soil 8-20 part; Zuoyun soil 6-15 part, green grass mountain range 7-15 part, white glues mud 11-20 part; Feldspar 5-15 part, Ninghai soil 1-5 part newly can native 1-5 part.
Said novel high-strength porcelain insulator does not have the glaze flexural strength greater than 188Mpa, and tensile strength is greater than 115MPa.
The preparation method of above-mentioned novel high-strength porcelain insulator; At first with raw material in the ratio weighing for preparing, the water that adds base-material raw material gross weight 30% obtains slurry, then slurry is carried out ball milling 9-10 h; The new slurry that obtains carries out press filt through after screening out iron; The mud cake that obtains extrudes in vacuum deairing machine, and the mud section that obtains is carried out electricity again and dried in the shade, and promptly obtains green compact after last moulding, the drying; Green compact through glazing, burn till, behind the mucilage binding finished product to the end.
The invention has the beneficial effects as follows: porcelain insulator good mechanical property of the present invention and production cost are low, are easy to technology controlling and process.Raw materials usedly be existing conventional ceramic raw mineral materials, adopt Jingyang soil, shorten the ball milling time, not only reduced cost but also can improve use characteristics.Another characteristics of this prescription are clays of rational Match different minerals type, are that material has the favorable manufacturability ability, and particularly firing property is easy to technology controlling and process, improves porcelain spare qualification rate.
