Problems solved by technology

Although they can basically meet the cleaning requirements, on the one hand, most cleaning agents are highly dependent on the type of solder and flux, the cleaning range is limited, the stability is poor, volatile and harmful to human health
On the other hand, the preparation methods of most cleaning agents are cumbersome, and some need to introduce other auxiliary equipment, and the composition of cleaning agents is complex, which will cause corrosion to solder joints, and a large number of bubbles will be generated during the cleaning process, which cannot be used for fully automatic cleaning and cleaning. ultrasonic cleaning

preparation example Construction

[0051] A preparation method of low-volatility high-performance water-based cleaning agent, is characterized in that, comprises the following steps:

[0052]According to the composition and content ratio contained in the water-based cleaning agent described in any one of claims 1-7, the raw materials of each component are measured respectively, and the method of heating in a water bath is kept at 30 ± 5 ° C. Add deionized water into the reaction kettle to start stirring, then add surfactant, corrosion inhibitor and defoamer respectively, continue stirring until completely mixed, stop stirring and let stand.

[0053] A low-volatility high-performance water-based cleaning agent cleaning method is characterized in that it comprises the following steps:

[0054] 1) The parts to be cleaned are at 80°C + Soak in water at 2°C for 35~50min;

[0055] 2) Put the configured cleaning agent and the parts to be cleaned in the ultrasonic cleaning machine, adjust the initial temperature to 6...

Embodiment example 1

[0071] The composition of the low-volatility high-performance water-based cleaning agent is as follows: surfactant accounts for 6% by weight, wherein Tween 20: Surfynol 420: dodecylalanine: cetyltrimethylammonium chloride=3: 3:2:2, 0.01% corrosion inhibitor is isopropylamine, 0.01% defoamer is polyether modified silicone oil, and the balance is deionized water.

Abstract

The invention provides a low-volatilization high-performance water-base detergent and a cleaning method. The low-volatilization high-performance water-base detergent is prepared from the following rawmaterials in percentage by mass: 6-12% of a surfactant, 0-0.1% of a corrosion inhibitor, 0-0.5% of a defoaming agent and the balance of deionized water, wherein the surfactant is prepared from a nonionic surfactant, a zwitterionic surfactant, a binary star nonionic surfactant and a cationic surfactant through compounding; the nonionic surfactant and the binary star nonionic surfactant account for50-69% of the total weight of the surfactant; the zwitterionic surfactant accounts for 10-25% of the total weight of the surfactant; and the cationic surfactant accounts for 15-35% of the total weight of the surfactant. Together with a cleaning process, the detergent is capable of strongly removing surface residues after welding of a rosin type welding flux, a welding point is kept bright, and good surface insulation is achieved; and compared with a conventional detergent, the detergent is completely low in volatilization, safe and environmental-friendly, free of pollution substance, free ofbubble in the cleaning process, and easy in cleaning process operation.

Description

technical field [0001] The invention belongs to the field of cleaning agent manufacturing in the electronic industry, relates to a low-volatility high-performance water-based cleaning agent and a cleaning process, and is particularly suitable for post-welding cleaning of electronic component pins and their surfaces. Background technique [0002] With the development of the electronics industry, the requirements for the quality of electronic products are getting higher and higher. After the welding is completed, flux residues or other foreign pollutants not only affect the appearance of the product, but also deteriorate the reliability of the product, causing short circuits, corrosion, and other electrical failures. [0003] Traditional cleaning agents containing ODS substances such as freon have a good cleaning effect on grease rosin and other resins. However, such cleaning agents contain substances that destroy the ozone layer. Improper use of halogens and their compounds ...
