Anti-aging ceramic insulator and preparation method thereof

Abstract

The invention discloses an anti-aging ceramic insulator and a preparation method thereof, and relates to the technical field of an insulator. The anti-aging ceramic insulator is prepared from the following raw materials in parts by weight: 20 to 32 parts of potassium feldspar, 15 to 24 parts of zeolite, 25 to 30 parts of mica, 8 to 16 parts of kaolin, 15 to 22 parts of epoxy resin, 10 to 18 partsof organic silicon, 10 to 20 parts of ceramic fiber, 6 to 10 parts of zirconium dioxide, 7 to 15 parts of calcium silicate, 4 to 10 parts of nanometer silicon dioxide, 4 to 10 parts of nanometer titanium dioxide, 3 to 8 parts of nanometer silicon nitride, 3 to 6 parts of silane coupling agents, 3 to 6 parts of antioxidants, 2 to 5 parts of anti-freezing agents and 3 to 6 parts of surface active agents. The anti-aging ceramic insulator has the advantages that the property is stable; the corrosion resistant performance and the anti-aging performance are good; the low temperature and high temperature resistant performance is good; strong mechanical stress is realized; the preparation method is simple and easy; the manufacturing cost is low; good market application prospects are realized.

Description

technical field

[0001] The invention relates to the technical field of insulators, in particular to an aging-resistant ceramic insulator and a preparation method thereof. Background technique

[0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. Insulators were mostly used on utility poles in the early years, and gradually developed into high-voltage wire connection towers where many disc-shaped insulators were hung at one end. It was used to increase the creepage distance and was usually made of glass or ceramics. A device capable of withstanding voltage and mechanical stress installed between a conductor at a different potential or between a conductor and a grounded member. There are many types of insulators in different shapes. Although the structure and shape of different types of insulators are quite different, they are all composed of two parts: insulating parts and connecting fittings.
