Abstract
The invention relates to cleaning liquid, in particular to environmentally-friendly water-based multifunctional electronic cleaning liquid for the electronic surface mount industry. The cleaning liquid comprises the following components in parts by weight: 35-60 parts of pure water, 1-3 parts of corrosion inhibitor, 3-5 parts of isomerous alcohol ether phosphate, 3-12 parts of alkaline auxiliary agent, 7-12 parts of secondary alkyl sulfonate, 3-8 parts of EO-PO (Ethylene Oxide-Propylene Oxide) copolymer, 10-25 parts of D-limonene and 5-10 parts of nonionic emulsifier. The cleaning liquid is safe to a cleaned object, cannot corrode an electronic circuit board, has excellent compatibility, good compatibility with most rubber and plastics and cannot cause swelling, corrosion, and the like, thus the cleaning liquid can be widely applied to electronic circuit boards and hardware plastic; the cleaning liquid can be used for cleaning residual soldering fluxes or residual tin cream and other dirt on a PCBA (Printed Circuit Board Assembly) at normal temperature or by warming up, and also can be used for cleaning heavy greasy dirt on hardware or plastic parts; and the cleaning liquid is an aqueous concentrated product, has strong cleaning power, can maintain good electrical performance for the PCBA and has no damages to the human body.
Description
Technical field: [0001] The invention relates to a cleaning liquid, in particular to an environmental-friendly water-based multifunctional electronic cleaning liquid for the electronic surface mounting industry. Background technique: [0002] In the surface mount technology in the electronics industry, traditional halogenated hydrocarbon solvents such as freon, trichloroethane, and trichloroethylene are used to clean electronic circuit boards, because of their strong cleaning ability, no flash point, and fast drying speed. However, this type of cleaning solution has many disadvantages, which are very harmful to the human body, the environment and the objects to be cleaned. To the human body: the above-mentioned halogenated hydrocarbon solvents are very toxic. Long-term exposure to or inhalation of vapor by the human body can easily cause liver, kidney, blood poisoning, dizziness, vomiting, etc. It decomposes to form highly phosgene, which is carcinogenic. To the environmen...
