Embodiment 1

[0027] A kind of cleaning agent for electrical equipment, its composition and weight are as follows: (take 1000g product as example)

[0028]

[0029] A preparation method of cleaning agent for electrical equipment, the steps are as follows:

[0030] (1) Pump the C12 isoparaffin into the storage tank (the bottom is conical) and let it stand still for more than 24 hours to remove impurities and moisture at the bottom, and then pump it into the reaction kettle;

[0031] (2) propylene glycol methyl ether, methylene dichloride, tetrachloroethylene, limonene are added in the reactor successively;

[0032] (3) Stir the materials in the reaction kettle evenly for 20-30 minutes, and after passing through the dryer and filter, this product is the cleaning agent for electrical equipment.

Abstract

The invention relates to an electrical equipment cleaning agent and a preparation method thereof. The electrical equipment cleaning agent comprises 1 to 5% of one or more alcohol ether solvents, 5 to 10% of dichloromethane, 30 to 50% of tetrachloroethylene, 0 to 10% of limonene and the balance one or more hydrocarbon solvents. The preparation method comprises the following steps of standing the one or more hydrocarbon solvents in a storage tank having the cone-shaped bottom for more than 24 hours, adding the one or more hydrocarbon solvents into a stainless steel reactor according to a certain ratio, orderly adding the one or more alcohol ether solvents, dichloromethane, tetrachloroethylene and limonene into the stainless steel reactor, stirring for 20 to 30 minutes, drying by a dryer and filtering by a filter to obtain the electrical equipment cleaning agent. The electrical equipment cleaning agent does not contain ozone depleting substance (ODS) raw materials of trifluorotrichloroethane (F-113), 1,1,1-trichloroethane, trichloroethylene and carbon tetrachloride, is safe and environmentally friendly, has an ozone destruction coefficient of 0.00, strong detergency of 99.9% and a strong capacity of removing mineral oil stains, soldering and dust, allows on-line cleaning, has withstand voltage more than 25KV and stable chemical properties, does not produce corrosion on circuit boards and metal materials, and can be volatilized fully without residual.

Description

technical field [0001] The invention belongs to the field of chemical cleaning, and relates to a cleaning agent, in particular to a cleaning agent for electrical equipment and a preparation method thereof. Background technique [0002] With the continuous development of the cleaning industry, in order to ensure the safety of people and equipment, the cleaning requirements for electrical appliances, instruments, power distribution cabinets, etc. are getting higher and higher. The traditional cleaning agents are F113 (trifluorotrichloroethane), 11.1 trichloroethane, trichloroethylene, carbon tetrachloride, toluene, xylene, etc. It has brought many hazards to people, objects to be cleaned and the environment. High toxicity, large evaporation loss, environmental pollution, ozone destruction, etc. In order to reduce the harm of cleaning to human health and the environment, green cleaning has become a way for the sustainable development of the cleaning industry. my country has ...
