preparation example Construction

[0050] A method for preparing a low-foaming high-efficiency water-based cleaning agent. According to the ingredients and content ratios contained in any one of the aforementioned water-based cleaning agents, the raw materials of each component are measured respectively, and at normal temperature and pressure, in a room with a stirrer 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.

[0051] A low-foaming high-efficiency water-based cleaning agent cleaning method is characterized in that it comprises the following steps:

[0052] 1) Soak the parts to be cleaned in water at 80℃+2℃ for 35~50min;

[0053] 2) Put the configured cleaning agent and the parts to be cleaned in the ultrasonic cleaning machine, adjust the initial temperature to 60°C-65°C, and ultrasonically clean for 25~40min. The power of the selected ultrasonic machin...

Embodiment 1

[0057] The composition of the low-foaming high-efficiency water-based cleaning agent is as follows: Surfactant accounts for 6% by weight, of which fatty alcohol polyoxyethylene ether: cetyltrimethylammonium chloride: Surfyonl440=5:4:1, corrosion inhibitor 0.01% agent is benzotriazole, 0.01% defoamer is polyether modified silicone oil, and the balance is deionized water.

Embodiment 2

[0059] The composition of low-foaming high-efficiency water-based cleaning agent is as follows: Surfactant accounts for 7% by weight, of which Tween 20: Tetradecyltrimethylammonium chloride: Surfyonl440=6: 3: 1, corrosion inhibitor 0.02% , is benzotriazole, defoamer 0.018%, is polyether modified silicone oil, and the balance is deionized water.

Abstract

The invention provides a low-foam high-efficiency water-base detergent and a cleaning method. The low-foam high-efficiency water-base detergent is prepared from the following raw materials 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 a nonionic surfactant is prepared from any one, two, three or four of fatty alcohol-polyoxyethylene ether, Tween-20, alkylphenol polyoxyethylene 9-ether and triethanolamine through mixing in a respective mass ratio greater than 0%; and a cationic surfactant isprepared from any one, two or three of hexadecyl trimethyl ammonium chloride, tetradecyl trimethyl ammonium chloride and dodecyl trimethyl ammonium chloride through mixing in a respective mass ratiogreater than 0%. 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 the detergent is low in volatilization in the cleaning process, free of pollution substance which can affect health of operators, and in addition free of bubble in the cleaning process.

Description

technical field [0001] The invention belongs to the field of cleaning agent manufacturing after circuit welding and assembly, and relates to a low-foaming high-efficiency water-based cleaning agent and a cleaning process method. In particular, it relates to cleaning agents suitable for post-soldering product cleaning of electronic products, especially in surface mount technology. Background technique [0002] SMT is currently the most popular technology in the electronic assembly industry. It is mainly to solder and assemble SMC / SMD on the surface of PCB or other substrates by reflow soldering or dip soldering. Throughout the development cycle of the entire electronics industry, although China's SMT industry is in the early stages of development, it has already entered the right track and is showing a trend of vigorous development. With the miniaturization and precision of electronic products, it is inevitable that flux, flux, solder paste and other residues or other foreig...
