Description
Technical Field
The invention belongs to the technical field of cleaning agents, and particularly relates to an insulating electronic component cleaning agent, a preparation method and application thereof.
Background
All-weather continuous acquisition, identification, modulation, conversion, transmission and processing of various forms and various types of information are carried out on various charged devices. In the long-term continuous operation process of the equipment, various dust, moisture, oil smoke, acid gas, salt, metal dust, static electricity and various charged particles are deposited on the surface of the equipment by physical adsorption, so that serious pollution of the equipment is caused, the heat radiation capability of the equipment is reduced, and the operation quality and the operation reliability are reduced. These contaminants also create additional "microcircuitry effects" on the circuitry within the device, resulting in "corrosion-inhibiting" effects, causing poor contact with the device, reduced impedance, leakage, short circuits, bit errors, bad plates, etc., and also causing soft failures such as increased line energy loss, signal attenuation, malfunction, rate and quality instability.
There are two ways to clean the electrification equipment: firstly, the traditional physical method is that blowing, sweeping and wiping after power failure, and the power-on operation is continued after the cleaning agent and/or water are completely evaporated; the cleaning mode affects the normal operation of the equipment, and once cleaning agent or water remains on the equipment, short circuit and damage to the equipment can be caused. And secondly, the electric power is continuously cut off, and chemical cleaning with excellent electric insulation is used for carrying out electrified cleaning. However, the ODS solvent is added into the product at present, so that the substance has extremely strong damage to the ozone layer, has certain toxicity and is not friendly to operators and the environment. For example, CN202110306874 discloses a cleaning agent for electrical equipment, wherein dichloroethane and trifluorotrichloroethane are used as ODS, and dichloroethane is a medium and high toxic substance, has carcinogenic effect, and can generate paralysis effect on central nervous system after long-term use. Can cause damage to liver, kidney, heart and trigeminal nerve. For example, the patent application with the application number of CN202110156661 discloses a cleaning agent for a power transformer, and the dichloropentafluoropropane in the raw material belongs to halogen-containing substances and has a depletion effect on an ozone layer; more than 50 parts of tetrachloroethylene is also used, and high concentrations of tetrachloroethylene can lead to dizziness, headache, drowsiness, confusion, nausea, difficulty speaking and walking, loss of consciousness and death. On 10 and 27 days 2017, the world health organization international cancer research institute published a list of carcinogens, tetrachloroethylene (perchloroethylene) was in the class 2A carcinogen list. Tetrachloroethylene (perchloroethylene) was listed in the list of toxic and hazardous water contaminants (first lot) at day 7 and 23 of 2019.
Therefore, how to obtain a cleaning agent which is friendly to the environment and cleaning personnel and is used for cleaning electrical equipment without power failure is a problem to be solved.
Disclosure of Invention
In order to overcome the problems in the prior art, the invention provides an insulating electronic component cleaning agent, a preparation method and application thereof, wherein the cleaning agent has good compatibility with all electronic components, excellent electrical insulation performance, and can realize uninterrupted cleaning of electrified equipment, and meanwhile, the cleaning agent has good cleaning power and certain anti-fouling capability; and the product has low odor, no residue, no aromatic hydrocarbon solvent and no ODS component, and is double friendly to environment and cleaning personnel.
The purpose of the invention is realized in the following way:
the invention provides an insulating electronic component cleaning agent, which comprises the following raw materials in parts by weight:
| solvent oil | 40-70 |
| N-methylpyrrolidone | 3-10 |
| D-limonene | 2-15 |
| Diethylene glycol butyl ether | 5-15 |
| Silicone | 2-5 |
| Nonionic surfactant | 1-5 |
| Antistatic agent | 0.1-3 |
。
Further, the raw materials of the cleaning agent also comprise alcohols, and the weight ratio of the alcohols is as follows:
| alcohols | 2-10 |
。
Further, the solvent oil is low-odor environment-friendly solvent oil with desulfurization, denitrification and dearomatization, and specifically one or more of D30, D40, D60, D70 and D80 (commercial brand of solvent oil). Wherein, D30 volatilizes fast, the flash point is low, can be used in the open space; if in a closed space, a formula with high D80 proportion can be adopted.
Further, the alcohol is one or two of ethanol or glycol. The micromolecular alcohols have good permeability, are easier to permeate into dirt, and provide conditions for subsequent cleaning.
Further, the siloxane is one or a mixture of more than one of polydimethylsiloxane, tetramethyl cyclotetrasiloxane and octamethyl cyclotetrasiloxane. The siloxane has good electrical insulation property, certain anti-fouling capability, and can improve the pressure resistance of the cleaning agent, and meanwhile, a layer of protective film with high insulation property is formed on the surface of the electronic equipment, so that the electronic equipment can be hydrophobic and dustproof. The cleaning frequency can be reduced after long-term use.
Further, the nonionic surfactant is any one or a mixture of several of fatty alcohol polyoxyethylene ether, alkylphenol polyoxyethylene ether and alkyl glycoside.
Further, the antistatic agent is ethoxy cocoalkylamine.

The solvent oil is low-odor environment-friendly solvent oil with desulfurization, denitrification and dearomatization, has low odor, is nontoxic and non-irritating, and is safer for users; meanwhile, the solvent is a nonpolar solvent, and can effectively dissolve oil stains on the surface of an object according to a similar compatibility principle, so as to achieve a certain cleaning effect. The solvent oil used in this example was a mixture of three of D40, D60 and D80.
The N-methyl pyrrolidone is a polar solvent with good stability, and is an excellent cleaning agent for high-precision electronics, circuit boards and lithium batteries. The two are matched for use, so that the detergency of the cleaning agent can be improved, and the swelling of plastics can be avoided.
The D-limonene is a natural ingredient in a variety of fruits (mainly citrus), vegetables and spices, has very good permeability, and can rapidly remove dirt on hard surfaces. In addition, the raw material is lemon-flavored liquid, and the lemon-flavored liquid can bring pleasant smell to the product when being added into a system.
The ethoxy coco alkylamine is used as an antistatic agent, can effectively disinfect static accumulation generated by equipment friction, prevent static interference and dust adhesion, and can effectively enhance the anti-fouling performance of equipment.
The preparation method of the insulating electronic component cleaning agent comprises the following steps:
all raw materials in the cleaning agent are added into a normal pressure closed container according to the weight part ratio shown in the table 3, and stirred for 0.5-1h at the speed of 50-200r/min under the condition of 20+/-10 ℃ to obtain the insulating electronic component cleaning agent.
The application method of the insulating electronic component cleaning agent comprises the following steps: spray washing or soaking method is adopted. Specifically, when a spray washing method is selected, compressed dry air is needed to blow off dust, iron powder and other impurities on the surface of the circuit board to be washed, and then a spray gun is used for sucking a cleaning agent for spray washing. If the equipment is seriously polluted, repeated spray washing is needed. After cleaning, the cleaning agent is quickly dried, and can be dried by using dry air to help the cleaning agent to volatilize quickly. For small-sized electrical equipment or parts, the small-sized electrical equipment or parts can be directly soaked for 10 minutes and then fished out.
