Abstract

The invention discloses an anti-aging electric porcelain insulator, and belongs to the field of insulators. The insulator comprises a porcelain base body and an anti-aging coating positioned on the porcelain base body. The porcelain body matrix comprises the following raw materials: silicon resin, a flexible prepolymer, an organic solvent, polyol, isocyanate and a chain extension cross-linking agent; the anti-aging coating comprises the following raw materials: hydroxyl silicone oil, long-chain alkyl silane, a binder and a diluent. According to the anti-aging electric porcelain insulator, organic silicon resin is subjected to pyrolysis, organic matter ceramization is achieved, the porcelain body base body is prepared, then pores of the porcelain body base body are filled with the elastomer, on one hand, the elastomer can improve the mechanical strength of the material, and on the other hand, after long-term use, the elastomer can prevent the expansion of stress microcracks generated in the ceramic body matrix, and avoids the aging phenomenon caused by the stress microcracks to a certain extent.

Description

technical field [0001] The invention relates to the field of insulators, in particular to an anti-aging electric porcelain insulator and a preparation method thereof. Background technique [0002] As an important part of the electric power industry, electric porcelain refers to electric porcelain materials used in voltage levels exceeding 1000V, widely used in transmission and distribution lines, electrical equipment and power stations, and is an indispensable and important insulating material for the development of the electric power industry. With the rapid development of the economy and the continuous improvement of people's living standards, the demand for electricity as a clean energy is increasing day by day. With the development of electric power, the demand for electric porcelain products is also increasing day by day, forming a huge market space. However, if the insulator is operated outdoors or in a harsh environment for a long time, the aging phenomenon of the in...
