Ceramic insulator with self-cleaning glaze and preparation method of ceramic insulator

Abstract

The invention provides a ceramic insulator with self-cleaning glaze and a preparation method of the ceramic insulator, and relates to the field of insulators. The ceramic insulator with the self-cleaning glaze comprises a ceramic insulator body and a glaze layer on the outer surface of the ceramic insulator body, wherein the glaze layer is prepared from the following raw materials in parts by weight: 35 to 45 parts of quartz, 10 to 20 parts of porcelain powder, 10 to 20 parts of albite, 5 to 10 parts of calcite, 5 to 10 parts of nano calcium carbonate, 2 to 5 parts of talc, 5 to 10 parts of kaolin, 4 to 8 parts of silicon oxide micro powder, 2 to 6 parts of polyvinylidene fluoride, 2 to 6 parts of nano titanium dioxide, 2 to 5 parts of zinc oxide nanofibers, 45 to 55 parts of boric acid, 4 to 8 parts of epoxy resin and 1 to 5 parts of carboxymethyl cellulose. By optimally selecting the glaze layer material meeting the requirements, etching the surface of the ceramic insulator body by adopting the glass etching liquid, and coating the glaze layer on the surface of the dried ceramic insulator body by adopting an atomization spraying mode, pollutants cannot be buried on the surface of the ceramic insulator, rain, snow, ice, dust and the like are not easy to attach, and surface dirt does not need to be removed.

Description

technical field [0001] The invention relates to the field of insulators, in particular to a ceramic insulator with self-cleaning glaze and a preparation method thereof. Background technique [0002] Pollution flashover refers to the pollution attached to the insulating surface of electrical equipment, under humid conditions, its soluble substances gradually dissolve in water, forming a conductive film on the insulating surface, greatly reducing the insulation level of the insulator, and appearing under the action of electric field force Strong discharge phenomenon, voltage, pollution, and humidity are the three necessary conditions for pollution flashover. To prevent pollution flashover, measures should be taken in these three aspects, such as increasing the creepage ratio distance, reducing surface pollution, increasing surface dry area, using New insulators, etc., in order to destroy the formation of pollution flashover conditions and avoid accidents. [0003] In order to...
