Abstract

The invention relates to the technical field of insulators, and provides a low-temperature-resistant anti-pollution flashover porcelain insulator and a manufacturing process thereof. According to the invention, the polymer is utilized to coat the modified nanoparticles and the water reducing agent containing the amino acid ionic liquid component, and the two components have a synergistic effect, so that the comprehensive performance of the porcelain insulator is jointly improved; and polyester, modified nanoparticles and olefin are copolymerized to obtain uniformly dispersed polymer coated modified nanoparticles, and the insulator raw material is subjected to ball milling twice, so that the binding property between organic matters and inorganic matters in the insulator raw material can be improved, the ball milling efficiency is improved, and the ball milling effect is improved. The porcelain insulator prepared by the invention has good electrical performance, mechanical performance, hydrophobic performance and temperature resistance.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a porcelain insulator resistant to low temperature and anti-pollution flashover and a manufacturing process thereof. Background technique [0002] Porcelain insulators provide support and insulation for transmission lines, so the requirements for both mechanical strength and dielectric strength are relatively high, and the natural environment in my country is relatively complicated. Porcelain insulators are mostly used in outdoor or even field environments, so porcelain insulator products are also required Can adapt to complex environmental conditions. [0003] The working environment and working conditions of insulator products are extremely harsh, and are affected by factors such as sudden changes in cold and heat, extreme heat, severe cold, high pH, ​​and high pollution. During the operation of insulator products, not only must withstand the power frequency voltage under no...
