Problems solved by technology

Silicone electric porcelain waste is difficult to crush, and its performance is poor, and its reuse is not efficient. Therefore, there is no report on the research and development of this aspect
At present, some enterprises add aluminum insulator waste in the process of preparing high-alumina insulators to save resources and further improve the mechanical properties of high-alumina insulators. However, as the market share of aluminum insulators increases, resulting in high-alumina insulators Mineral resources are dwindling

Abstract

The invention discloses a high-strength silicon brown-glazed electric porcelain and a preparation method thereof, and relates to the technical field of silicon electric porcelain. The raw materials of the high-strength siliceous brown glaze electric porcelain disclosed by the invention include blanks and brown glazes, and the blanks are composed of the following raw materials: kaolin, wollastonite, Jiepai mud, siliceous porcelain waste powder, and low melting point glass powder , spodumene, yttrium oxide, ceramic grade talcum powder and crystal nucleating agent; the brown glaze glaze is made up of the following raw materials: potassium feldspar powder, quartz powder, this blank mud, calcite powder, cooked talcum powder, iron oxide, Network green, manganese trioxide and Jiepai mud, and discloses the preparation method of the brown-glazed electric porcelain. The siliceous brown glaze electric porcelain raw material of the present invention is simple and easy to obtain, has low cost, high bending strength, and good plasticity and stability; the cost of the brown glaze material is low, the dipping time is short, and the glaze effect is good , the glaze surface is rosy and full, bright and lustrous, the color is stable, no color difference, and the strength of the brown glazed electric porcelain is increased by more than 10% compared with that before unglazed.

Description

Technical field [0001] The present invention belongs to the field of technology siliceous ceramic, particularly to a high-strength porcelain enamel brown siliceous their preparation. Background technique [0002] Porcelain ceramic is an electrically insulating material, has good insulating properties and mechanical strength, used in power system and its supporting effect of the insulating member, the container may double as the other electrical components, thus, mechanical properties, electrical properties thereof , have high environmental resistance requirements. In recent years, with the power system transmission lines voltage levels continue to increase, more and more widespread application of electrical porcelain insulators, has become one of the few times the electrical wiring main structural parts. Currently, the bending strength of foreign porcelain insulators can reach 150MPa and high reliability, and low performance of domestic insulators and reliability, resulting in my...
