Waterborne cleaning agent for PCB circuit board as well as preparation and application thereof

The invention discloses waterborne cleaning agent for PCB circuit board as well as preparation and application thereof. The waterborne cleaning agent is prepared from the following components in parts by mass: 0.5 to 1 part of benzotriazole, 2 to 4 parts of amine acid acyl sodium laurate, 2 to 4 parts of iso-tridecanol polyoxyethylene ether, 5 to 6.6 parts of triethylene glycol momobutyl ether, 1 to 2.2 parts of sodium isooctyl sulfate, 3 to 4.2 parts of terpenol, 5 to 6 parts of monoethanolamine, 2 to 3 parts of hydroxyl alkyl sulfonic betaine, 5 to 6.8 parts of dipropylene glycol n-butyl ether, 6 to 7.7 parts of tripropyleneglycoln-butylether, 0.5 part of defoaming agent, and 54 to 68 parts of deionized water. With water as a cleaning medium, a series of water-based cleaning agent auxiliaries such as surfactant, auxiliaries, corrosion inhibitor and chelating agent are added, water-soluble agent and non-polarity pollutants are removed, and meantime, white powder is not remained during cleaning, and the phenomenon of corrosion of cleaned workpieces is avoided; and in addition, the waterborne cleaning agent is simple, safe and environmentally friendly during using, has the advantages of strong seepage force and strong dissolving power, and the water for washing the board after cleaning is noncorrosive.
