Embodiment 1

[0013] A new type of high-strength porcelain insulator, which is made of the following raw material formula in parts by weight: 3 parts of black clay, 35 parts of bauxite, 8 parts of Zhangcun soil, 8 parts of Jingyang soil, 8 parts of Zuoyun soil, and 11 parts of Qingcaoling , 15 parts of white clay, 8 parts of feldspar, 2 parts of Ninghai soil, and 2 parts of Xinhui soil are prepared. First, the raw materials are weighed according to the prepared ratio, and water with 30% of the total weight of the base material is added to obtain the slurry, and then the The slurry is ball milled for 9 hours, and the obtained new slurry is squeezed out after the iron is screened out. The obtained mud cake is extruded in a vacuum mud refiner, and the obtained mud section is then electric shade-dried, and finally formed and dried to obtain raw Blank; the final product is obtained after the green body is glazed, fired, and glued.

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 [0001] The invention belongs to the technical field of electric porcelain, and in particular relates to a formula of a novel high-strength porcelain insulator and a preparation method thereof. Background technique [0002] Electric porcelain billet refers to a mixture of clay raw materials, flux raw materials and other raw materials (quartz, high alumina raw materials or other mineral raw materials) in a certain proportion, which is ground and mixed into mud for billet making. The mud is simply referred to as billet. [0003] When determining the ratio of various raw materials, it must be ensured that the blank can meet the technical performance required by the electric porcelain production process and the physical performance requirements of the fired porcelain. The technological performance of the billet before firing only depends on the quality and amount of the clay raw material, while the firing process of the billet mainly depends on the flux raw mater...
