Abstract

The invention belongs to the technical field of electroceramic glazes, and in particular relates to a black glaze for insulators and a preparation method thereof. A black glaze for insulators comprises the following raw materials in parts by mass: 27-31 parts of Hunan high-potassium and low-sodium feldspar, Hunan high-sodium low-potassium feldspar 4-8 parts, ball clay 3-7 parts, hard kaolin 18-22 parts, calcined talc 9-13 parts, limestone 5-9 parts, quartz powder 21-25 parts, barium carbonate 1 ‑3 parts, black color base 6‑10 parts. After the insulator is made into porcelain with black glaze, the surface of the porcelain body is bright black, smooth and bright, delicate and moist, which can well meet the needs of customers for black electric porcelain. Moreover, the black glaze of this scheme can be well combined with the body. After the porcelain is formed, an excellent intermediate layer can be produced between the glaze and the body, which can greatly improve the performance of the porcelain (increase the strength of the porcelain by more than 22%). The development of black glaze achieves the design purpose and meets the company's technology and industry standards.

Description

technical field [0001] The invention belongs to the technical field of electric porcelain glazes, and in particular relates to a black glaze for insulators and a preparation method thereof. Background technique [0002] Electric porcelain refers to a type of porcelain insulator used in power industry systems, which is made of natural minerals such as bauxite, kaolin, and feldspar as the main raw materials and fired at high temperature, including various line insulators and insulators for power station appliances, as well as other charged bodies. Insulating part for isolation or support. Electric porcelain is an important basic device of the electric power industry. The electric porcelain manufacturing industry belongs to the field of equipment manufacturing industry supported by the country during the "Eleventh Five-Year Plan" period, and is the basic industry of the national economy. [0003] The surface of electric porcelain is usually coated with electric enamel. Electri...
