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, which are highly corrosive to human skin and relatively harmful to the environment, and are not suitable for large-scale use.
The dirt in the gaps between the sheds of the insulators is not easy to remove. In some heavily polluted areas, the surface of the insulators is very thick and dense. Manual removal is not only ineffective and inefficient, but it is also difficult to remove it only by high-pressure water washing. wash thoroughly

Abstract

The invention provides a cleaning composition for composite insulators with repairing function, belonging to the technical field of cleaning agents. The cleaning composition for composite insulators with repairing function provided by the present invention includes a dirt cleaning agent and an organic silicone rubber repairing agent, does not contain corrosive and prohibited substances, and is composed of surfactants with low surface tension, penetrating wetting agents. , builder, dust-proof agent, insulating layer repairing agent, etc. A variety of organic auxiliaries work together to spontaneously wet and spread on the surface of the insulator with contamination, so that the contamination will fall off the surface of the insulator, and it has a super high contamination removal ability. , significantly reducing wetting and brushing times. The functional silicone contained is deposited on the surface of the composite insulator to form a repair layer of 2 to 5 microns, repair the corroded and uneven parts of the surface layer, and restore the hydrophobicity and hydrophobicity of the surface. Effectively reduce the probability of subsequent contamination of the insulator and prolong the cleaning cycle.

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...
