Abstract
The invention relates to an antistatic printed circuit board cleaning agent which is prepared from the raw materials of, by weight: 2-3 parts of alkylbenzene lithium sulfonate, 4-5 parts of lauryl dimethyl amine oxide, 12-15 parts of propylene glycol butyl ether, 20-25 parts of isopropanol, 1-2 parts of alkenyl succinic acid, 20-24 parts of propylene glycol, 2-3 parts of disodium hydrogen phosphate, 10-12 parts of ethyl acetate, 3-4 parts of isopropylbenzene sodium sulfonate, 10-12 parts of ethylene glycol monostearate, 4-5 parts of an auxiliary agent, and 100-120 parts of deionized water. According to the invention, various surfactants such as anionic surfactant and nonionic surfactant are adopted, and are formed into an emulsion with water. The cleaning agent has excellent dissolving ability upon rosin and organic compounds, and has a good cleaning effect. Ethylene glycol monostearate is adopted, such that the cleaning agent has antistatic and pearlescent effects, and the circuit board can be protected. The water emulsion cleaning agent has the advantages of low cost, environment friendliness, and no pollution. The cleaning agent is suitable for high-precision circuit board cleaning. With the auxiliary agent, a protective film can be formed on the surface of the circuit board.
