Water-based printed circuit board polar material cleaning agent and preparation method thereof

The invention provides a water-based printed circuit board polar material cleaning agent. The cleaning agent is prepared from the following raw materials in parts by weight: 30-35 parts of dichloroperfluoropropane, 10-13 parts of dimethicone, 10-15 parts of sodium coconut oleate, 2-3 parts of sodium alkyl benzene sulfonate, 3-4 parts of isopropyl myristate, 30-40 parts of propylene glycol, 3-4 parts of sodium carbonate, 2-3 parts of gluconic acid, 20-30 parts of ethanol, 4-5 parts of auxiliary and 100-120 parts of deionized water. The cleaning agent has the beneficial effects that the cleaning agent uses dichloroperfluoropropane, propylene glycol and the like, has various additive surfactants, forms emulsion with water, has excellent capability of dissolving rosin and organic compounds, has excellent cleaning effects on polar materials, can achieve cleaning without dead corners, and is suitable for high-precision circuit board washing; the auxiliary can form a protective film on the surface of the circuit board to isolate air to prevent water and other molecules in the air from corroding the circuit board; the cleaning agent is resistant to oxidation, prevents short circuit and is convenient for operation of the next preparation process.
