Background

With the rapid development of economy, air pollution caused by production and life is increasingly serious, and because the environmental air contains various tiny particle pollutants such as dust, salt, oil stain and the like, the pollutants are gradually deposited on long-term running electric power and electrical equipment over time to form a dust layer. The presence of such a layer of dirt not only affects the operating efficiency of the equipment, but also has a serious impact on the reliability of the electrical power equipment. The composition of the dust is extremely complex, including dust, inorganic anions and cations, oil stains and the like, and the dust covered on the equipment affects the heat dissipation performance of the equipment, so that the operation efficiency of the equipment is reduced. Inorganic cations and anions in the dirt not only corrode metal materials in the equipment, but also play a role in electric conduction, and serious conditions can cause short circuit, thereby causing immeasurable loss. Therefore, the electrical equipment operating for a long time must be periodically cleaned.

In order to reduce economic loss caused by cleaning power failure, an electrified cleaning mode is needed. However, the power electrical equipment bears high voltage in operation, so the provided cleaning agent has high insulativity and high breakdown voltage, the communication equipment is not influenced under the normal operation condition during cleaning, and meanwhile, the safety of cleaning personnel is ensured.

The charged cleaning agent containing one or more ozone depleting substances (ODS components) is non-flammable, non-flammable and non-explosive, has no corrosive influence on various metal parts and plastics, and has the characteristics of high efficiency and safety. However, the use of ODS components has been totally prohibited in the cleaning industry from 1/1.2006, according to the provisions of the Montreal protocol for ozone depletion substances. The main common ODS components for production and consumption in China are the following 10 types: CFC-11, CFC-12, CFC 113, halon 1211, halon 1301, carbon tetrachloride, 1,1, 1-trichloroethane, HCFC22, HCFC141b and methyl bromide.

In the insulating cleaning agent, the polar organic solvent and the non-polar organic solvent are compounded, so that the efficient solvent removal of oil stains and polar dirt can be enhanced. The polar organic solvent which can be used in the present invention may be one or more of ethanol, propanol, butanol, ethylene glycol, glycerol, isopropanol, acetone, ethyl acetate. The nonpolar organic solvent used in the present invention is one or more of C9-C12 linear alkane and C9-C12 branched alkane, and may be, for example, n-nonane, n-decane, n-undecane, n-dodecane, 2-methyloctane, 3-methylnonane, 2-methyldecane, 2, 5-dimethylnonane, etc.

The polyether-modified silicone is a surface active material generally comprising a terminal methylsiloxane as a hydrophobic main chain and one or more organic polar groups at the intermediate position, and the organic polar groups may be polyether groups, preferably polyoxyethylene ether, polyoxypropylene ether, allyl alcohol polyoxyalkyl ether, dimethylamine polyether, amino polyether or urea polyether. That is, one or more of the silicones obtained by modifying hydrogen-containing silicone oil with polyether modified silicone polyoxyethylene ether, polyoxypropylene ether, allyl alcohol polyoxyalkyl ether, dimethylamine polyether, amino polyether, or urea polyether used in the present invention.

Polyether modified silicones useful in the present invention can be prepared by the following method:

adding metered hydrogen-containing silicone oil, polyether (polyoxyethylene ether, polyoxypropylene ether, allyl alcohol polyoxyalkyl ether, dimethylamine polyether, amino polyether or urea polyether) and chloroplatinic acid into a 250m L four-neck flask provided with a stirrer, a thermometer, a condenser and a nitrogen gas guide tube, starting stirring, introducing 5min of nitrogen gas, slowly heating to 120 ℃ under the protection of the nitrogen gas, controlling the temperature to be constant, reacting for 7h, cooling, adding a certain amount of argil, stirring, taking out a product, and performing vacuum filtration to obtain the polyether modified organosilicon.

The organosilicon surface active substance has high surface activity and low surface energy of methyl, and simultaneously has high flexibility of a main siloxane main chain, and the methyl is densely arranged on the surface, so that organic groups are utilized to the maximum extent. Therefore, the polyether modified organic silicon can be used for cleaningThe surface tension of the lotion system is reduced to 20-30 mN.m^-1. The ultra-low surface tension can effectively wet the dirt on the surface of the electrical equipment, thereby achieving the purpose of efficiently and quickly removing the dirt.
