Background
The pollution sources of electric power equipment are many, salt, acid and alkali, gas of the acid and alkali, moisture or water in the pollution can form electrolyte solution, and the existence of carbon stain or inactive metal causes the surface of a circuit to generate galvanic cell reaction, which causes electrochemical corrosion, electric leakage, short circuit, electromigration and the like; the dry dust can cause poor contact of the contact points and discharge, thereby causing poor heat dissipation; acid, alkali and gas thereof can also directly corrode a circuit through oxidation reduction; the accumulation of static electricity to varying degrees will also cause breakdown of the element. The principle of the charged cleaning agent is to remove dirt according to the nature of the equipment pollutants, since the pollutants are classified into polar water-soluble residues, non-polar water-soluble residues, and non-polar non-water-soluble residues. The polymer cleaning agent adopts a solvent containing both polarity and non-polarity, can well dissolve various pollutants of polar water-solubility, non-polar water-solubility and non-polar non-water-solubility, and enables the cleaning to achieve satisfactory effect. The existing charged cleaning agent generally comprises a builder, a nonionic surfactant, a penetrating agent, an organic solvent and the like, belongs to a chemical cleaning agent, and is mainly used for dissolving pollutants through various chemical substances to achieve the purpose of cleaning, so that the following problems exist: for cleaning circuits such as insulators and the like, a high-pressure spray gun is generally adopted to spray cleaning liquid onto the surface of an object to be cleaned at a high speed, the retention time of the cleaning liquid on the surface of the object is short, and the cleaning liquid cannot well penetrate into dirt, so that the cleaning effect is poor. The other place has fungus pollution, and the problem of degerming is generally not considered in the existing cleaning agent, so that the cleaning is not thorough, and the fungus still grows in large quantity after being cleaned.
Disclosure of Invention
The invention provides an electrified cleaning agent for high-pressure jet cleaning and a preparation method thereof, and solves the problem that the final cleaning effect is influenced due to poor penetration of the existing electrified cleaning agent during high-pressure jet cleaning.

Comparative example 2
Essentially the same as in example 1, except that: the preparation method is different, and the preparation method of the embodiment comprises the following steps: mixing the raw materials at 1000 rpm for 30 min.
The products of examples 1-4 and comparative examples 1-2 were tested for their properties, and the results are shown in Table 1.
Leakage current: during the test, the insulating tube with the specification of phi 35mm, the wall thickness of 3.0mm, the length of 500mm, the test voltage of 150KV and the time of 1min is used, the leakage current of the insulating hollow tube is measured firstly, then one end port of the insulating hollow tube is blocked, the cleaning agent is filled, and then the power frequency withstand voltage and leakage current test is carried out.
As can be seen from Table 1, the charged cleaning agent of the present invention is safe, environmentally friendly and highly insulating for charged devices.
Cleaning effect experiment:
the artificially simulated dirt (0.2 g of magnesium sulfate, 0.2g of calcium carbonate, 0.2g of anhydrous sodium sulfate, 0.2g of potassium chloride and 2g of diatomite are uniformly mixed, then 7.2g of vaseline is added and uniformly mixed) is uniformly coated on the surface of a sample insulator porcelain bottle which is subjected to cleaning pretreatment and natural drying in the shade, the thickness of the sample insulator porcelain bottle is about 1mm, and the insulator after being coated is naturally dried in the shade. The spray gun used in the test sprays water mist to the insulator porcelain bottle for 3min, and then the insulator porcelain bottle is naturally dried in the shade. The weights of the insulator porcelain bottles before and after cleaning were weighed, and the dirt removal rate was calculated, and the specific results are shown in table 2.
The removal rate (%) of the dirt was 100% (weight of insulator porcelain bottle after coating dirt-weight of insulator porcelain bottle after cleaning)/(weight of insulator porcelain bottle after coating dirt-weight of insulator porcelain bottle before coating dirt)
As is clear from table 2, the charged cleaning agent of the present invention has a stain removal rate (%) of 98% or more and has a good cleaning effect. Compared with the method without adding the cleaning material (comparative example 1), the method has the advantages that the dirt removal rate is improved by 9.3 percent, and the cleaning effect of the charged cleaning agent can be effectively improved by adding the cleaning material; compared with the comparative example 2, the dirt removal rate of the cleaning agent is improved by 5.7%, the cleaning agent is treated by ultrasonic waves, so that the cleaning agent is favorable for dispersing and emulsifying the cleaning material, is more stable, is not easy to delaminate, and can effectively improve the cleaning effect.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
