Embodiment 1

[0019] Embodiment 1: A self-cleaning high-strength rod-shaped porcelain insulator, including an insulator body, and one or several nano-molecular structure layers are arranged on the surface glaze layer of the body.

[0020] The preparation method of the above-mentioned self-cleaning type high-strength rod-shaped porcelain insulator, the method comprises the following steps:

[0021] 1) Dilute dodecyltrimethoxysilane 150 times in anhydrous ethanol solvent; obtain impregnation solution;

[0022] 2) Use ropes to cover both ends of the insulator and completely immerse in the immersion solution obtained in step 1) by lifting and moving. Naturally volatilize until the surface is dry and smooth, the volatilization time is 3-5min. After the organic solvent volatilizes, the long-chain single molecule grows one or several layers of nano-molecular structures on the glaze layer on the surface of the insulator, such as figure 2 shown; finally put the insulator vertically on the ground,...

Embodiment 2

[0025] Embodiment 2: It is basically the same as Embodiment 1, except that the long-chain alkylsilane is any one of vinyltriacetylsilane and butadienyltriethoxysilane.

[0026] The dilution factor in step 1) is 200 times.

Embodiment 3

[0027] Embodiment 3: basically the same as Embodiment 1, the difference is that the long-chain alkylsilane is any of dodecyltrimethoxysilane, vinyltriacetylsilane, butadienyltriethoxysilane A sort of.

[0028] The dilution factor in step 1) is 100 times.

Abstract

The invention discloses a self-cleaning high-strength bar-shaped porcelain insulator. The insulator comprises an insulator body, and one or more nanometer molecular structure layers are arranged on the surface glaze layer of the body. The preparation method comprises the following steps: (1) diluting a functional material in ethanol solvent by a certain number of times to get impregnation liquid; and (2) dipping an insulator body into the impregnation liquid, hanging the insulator out after impregnation, growing one or more nanometer molecular structure layers on the surface of the insulator using long-chain unimolecules after the organic solvent on the surface of the insulator volatilizes, and finally, putting the insulator vertically on the ground and releasing a rope, thus obtaining the self-cleaning high-strength bar-shaped porcelain insulator. The advantage is as follows: by adding the nanometer molecular layers made of a membrane material to the surface of the insulator, the insulator has a good hydrophobic surface, contaminants can be hardly accumulated on the surface of the insulator, contaminants can be easily rinsed by rainwater after the insulator is contaminated, and the purpose of self-cleaning is achieved.

Description

technical field [0001] The invention belongs to the field of insulators, in particular to a self-cleaning high-strength rod-shaped porcelain insulator and a preparation method thereof. Background technique [0002] The insulators used in the electrified railway catenary are in the external natural environment all the year round, so changes in various natural conditions and various climate changes will have a great impact on them. For example, it is easy to be damp in rainy and snowy weather, covered with ice and snow in frosty climate, and lightning strikes will also have a certain impact, all of which can easily lead to flashover of insulators. But in addition, pollution flashover is the most likely to cause great harm to insulators used in electrified railway catenary, that is, flashover caused by pollution. The frequency of pollution flashover is not much among several kinds of external insulation, but the loss it causes is the largest, which is 10 times of the damage ca...
