Problems solved by technology

There are also some water-based insulator cleaning agents for cleaning, but the universality and functionality are poor, and only for metal or ceramic parts, or composite rubber parts are cleaned separately, and the overall cleaning efficiency is low; some insulator cleaning agents are used for scrubbing. Most of these cleaning agents contain organic solvents such as methylene chloride, trichlorethylene, and tetrachlorethylene, whi

Abstract

The invention provides a composite insulator cleaning composition with repairing function, and a preparation method thereof, and belongs to the technical field of cleaning agents. The composite insulator cleaning composition comprises a dirt cleaning agent and an organic silicon rubber repairing agent, does not contain corrosive and forbidden and limited substances, and consists of a surfactant with relatively small surface tension, a permeation wetting agent, a washing assistant, a dust-proof agent, an insulating layer repairing agent and the like. According to the invention, a plurality of organic auxiliary agents cooperate to spontaneously soak and spread on the surface of the insulator with the dirt, so that the dirt falls off from the surface of the insulator, the dirt removing capability is ultrahigh, and the wetting and scrubbing time is obviously shortened; the contained functional organic silicon is deposited on the surface of the composite insulator to form a repairing layer of 2-5 microns, so that the corroded and uneven part of the surface layer is repaired, and the hydrophobicity and hydrophobic mobility of the surface are recovered; and the contained dust-proof agent can effectively reduce the follow-up dirt storage probability of the insulator and prolong the cleaning period.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning composition for composite insulators with a repair function and a preparation method thereof. Background technique [0002] Insulators refer to devices that are installed between conductors of different potentials or between conductors and grounding components that can withstand voltage and mechanical stress. According to the different insulating materials used, they can be divided into porcelain insulators, glass insulators and composite insulators (also known as composite insulators). The more important one is the composite insulator, the insulator of which is composed of a glass fiber resin mandrel (or core tube) and an organic material sheath and shed. The organic protective material of the outermost layer of the composite insulator is silicone rubber (RTV), which mainly contains Si~O~Si bonds, has excellent insulation properties, corona resistance and arc...
