Problems solved by technology

Most of the water-based cleaning agents currently used have defects such as high alkalinity, high irritation to human skin, and poor degreasing effect.
Although organic solvents have fast dissolving speed to oil stains and high degreasing efficiency, most of them have the disadvantages of low flash point and poor operation safety.

Embodiment 1

[0013] According to the percentage by weight, take respectively 30% tetrachlorethylene, 6.5% dichloromethane, 58% saturated alkane (boiling range is 175-185 ℃), 5% ethylene glycol butyl ether and 0.5% benzo triazole.

[0014] Add the above weighed saturated alkanes, tetrachloroethylene, dichloromethane, ethylene glycol butyl ether, and benzotriazole sequentially into a container at room temperature, and stir until uniform to prepare a cleaning agent for electromechanical equipment.

Embodiment 2

[0016] According to the percentage by weight, take respectively 28% tetrachlorethylene, 3.8% dichloromethane, 62% saturated alkane (boiling range 175-185 ℃), 6% ethylene glycol butyl ether, 0.2% benzotri azole.

[0017] Add the above weighed saturated alkanes, tetrachloroethylene, dichloromethane, ethylene glycol butyl ether, and benzotriazole sequentially into a container at room temperature, and stir until uniform to prepare a cleaning agent for electromechanical equipment.

Embodiment 3

[0019] According to the percentage by weight, 20% of tetrachlorethylene, 71% of saturated normal alkanes (boiling range 175-185°C), 8% of ethylene glycol butyl ether, and 1% of benzotriazole were weighed respectively.

[0020] Add the above-mentioned weighed saturated n-alkane, tetrachloroethylene, ethylene glycol butyl ether and benzotriazole sequentially into a container at room temperature, and stir until uniform to prepare a cleaning agent for electromechanical equipment.

Abstract

The invention discloses a cleaning agent for electromechanical equipment. The cleaning agent comprises the following components in percentage by weight: 20-40 percent of halogenated hydrocarbon, 55-75 percent of petroleum solvent, 3-8 percent of butyl cellosolve and 0.05-1 percent of benzotriazole, wherein the halogenated hydrocarbon is one or the mixture of components comprising tetrachloroethylene and dichloromethane. The cleaning agent is not easy to burn at normal temperature, has good insulating property and voltage resistance, can be widely applied to the cleaning of various electrical equipment and mechanical equipment and has convenient raw material sources, low cost and simple operation. Large equipment can be cleaned by an injection method, and small equipment or parts can be cleaned by a dipping method.

Description

technical field [0001] The invention belongs to the field of cleaning agents, and relates to a cleaning agent, in particular to a cleaning agent for electromechanical equipment. Background technique [0002] When cleaning electrical and mechanical equipment, organic solvents or water-based cleaning agents can be used. Most of the water-based cleaning agents currently used have defects such as high alkalinity, high irritation to human skin, and poor degreasing effect. Although organic solvents have fast dissolving speed to oil stains and high degreasing efficiency, most of them have the disadvantages of low flash point and poor operation safety. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a cleaning agent for electromechanical equipment, which not only has high oil removal efficiency, but also has a high flash point, is safe and low-toxic. [0004] The purpose of the p...
