Problems solved by technology

[0003] The glazing process is essential in the production process of insulators. Most of the glaze formulations currently used are brown glazes, but it is easy to cause color difference and uneven glazing during sintering, and the sintering temperature is mostly above 1200°C. , and the existing formula is prone to glaze bubbles and other problems during the firing process
Therefore, when the insulator is placed outdoors for a long time, cracks will appear on the glazed surface due to the influence of the environment, which will lead to cracking of the porcelain body and reduce its performance

Abstract

The invention discloses high-strength suspension insulator head glaze and a preparation method thereof, and belongs to the technical field of insulator preparation. The suspension insulator head glaze is prepared from the following raw materials in parts by weight: 20-40 parts of aluminum oxide, 8-10 parts of kaolin, 3-6 parts of bentonite, 10-15 parts of aluminum ore tailings, 3-8 parts of white corundum, 5-7 parts of potassium feldspar, 1-4 parts of silicon nitride, 2-5 parts of zinc oxide, 1-2 parts of magnesium oxide and 1-2 parts of zirconium oxide. The head glaz has the advantages that through optimization of a glaze formula, the glaze surface is smooth and flat and is not easy to crack, so the quality of the glaze surface is ensured, and the mechanical strength and the electrical performance of the suspension insulator can be improved. Due to the fact that the aluminum ore tailings are adopted in the raw materials, the environment is protected, and resources are utilized.

Description

technical field [0001] The invention belongs to the technical field of insulator preparation, and in particular relates to a high-strength suspension insulator head glaze and a preparation method thereof. Background technique [0002] Suspension insulators are currently used on transmission lines not only because of their stable electrical, mechanical and chemical properties, but also because they can be used under various climatic conditions. In recent years, in order to ensure the mechanical strength of the suspension insulator, it is mainly designed from the structure of its head and the material of the porcelain body of the insulator, ignoring the change of the surface glaze. [0003] The glazing process is essential in the production process of insulators. Most of the glaze formulations currently used are brown glazes, but it is easy to cause color difference and uneven glazing during sintering, and the sintering temperature is mostly above 1200°C. , and the existing f...
