Abstract

The invention discloses a pin type porcelain insulator and a preparation method thereof and relates to the technical field of insulators; the pin-type porcelain insulator is prepared from the following raw materials in parts by weight: 16-24 parts of mullite12-20 parts of vermiculite, 12-18 parts of clay, 8-16 parts of zeolite powder, 10-18 parts of mica powder, 20-30 parts of allophane, 10-20 parts of medical stone, 2-6 parts of zircon sand, 4-10 parts of diatomite, 1-3 parts of sodium hexametaphosphate, 1-3 parts of nano silicon nitride, 1-5 parts of nano calcium carbonate, 0.8-1.4 parts ofsepiolite fiber, 0.4-1 part of lignin fiber, 1-5 parts of hexamethyldisilazane, 1-5 parts of dimethylformamide and 3-7 parts of vinyltriethoxysilane. The pin type porcelain insulator has the beneficial effects that the raw materials are reasonably matched, and a proper preparation method is adopted, so that the structural strength and breaking strength of the insulator are improved, and the service life of the insulator is prolonged.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a pin-type porcelain insulator and a preparation method thereof. Background technique [0002] An insulator is a special insulation control that can play an important role in overhead transmission lines. It plays two basic functions in overhead transmission lines, namely supporting wires and preventing current from returning to the ground, and also to increase creepage distance. Usually made of glass or ceramic. In practical applications, porcelain insulators have been widely used due to their advantages in weather resistance, mechanical strength and cost. There are many classifications of porcelain insulators. According to the structure, they can be divided into post (pillar) insulators, suspension insulators, pin insulators, butterfly insulators, tension insulators, anti-pollution insulators and bushing insulators. Insulators and power stations, electrical insulators, etc....
