Abstract

The invention belongs to the technical field of electric porcelain glaze, and particularly relates to black glaze for an insulator and a preparation method of the black glaze. The black glaze comprises the following raw materials in parts by mass: Hunan high-potassium low-sodium feldspar 27-31 parts, 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 and black color base 6-10 parts. After the black glaze for the insulator and a green body form porcelain, the surface of the porcelain body is bright black, smooth, bright, fine, mild and moist, and the requirements of customers on black electric porcelain can be well met. Moreover, the black glazein the scheme can be well combined with the blank body, an excellent middle layer can be generated between the glaze and the blank body after the black glaze is formed into the porcelain, the performance of the porcelain can be greatly improved (the strength of the porcelain is improved by 22% or above), and the black glaze for the insulator is developed to achieve the design purpose and meet theprocess and industry standards of companies.

Description

Technical field [0001] The present invention belongs to the field of technology enamel frit, particularly, to a black glaze insulator and preparation method thereof. Background technique [0002] It refers to the porcelain alumina, kaolin, feldspar and other natural minerals as the main raw material for a class of ceramic insulators used in power industry through high-temperature firing systems, including various plant line insulators and electrical insulators, and other charged body an insulating spacer or supporting member used. Porcelain is an important basis for the device power industry, porcelain manufacturing belong to the field of equipment manufacturing industry supported by the state "Eleventh Five-Year" period, it is the basic industry of the national economy. [0003] Porcelain enamel surface is usually coated with an electrical, electrical means applied to the enamel surface of the body is electrically porcelain glaze, the glaze can be applied to improve the electric...
