Abstract

The invention relates to the technical field of cleaning agents, in particular to a water-based type soldering flux cleaning agent and a preparation method thereof. The water-based type soldering fluxcleaning agent is prepared from the following raw materials in parts by weight: 20 to 40 parts of fatty amine, 20 to 40 parts of glycol ether, 5 to 15 parts of non-ionic surface active agent, and 10to 30 parts of deionized water. The water-based type soldering flux cleaning agent provided by the invention is a water-based type cleaning agent, does not contain a fluoro-carbon solvent and a halogenated hydrocarbon solvent harmful to a human body so as not to hurt human health, is convenient to use, safe, environmentally-friendly, non-toxic and economical, and simple in use method, can be usedfor soaking or ultrasonically cleaning, and is capable of remarkably improving the cleaning work efficiency of parts. The water-based type soldering flux cleaning agent provided by the invention has ahigher cleaning effect on a soldering flux, and can be used for cleaning the soldering flux and welding slags on workpieces; electronic parts treated through the cleaning agent are clean in surface,and can be directly assembled or packaged after being subjected to water rinsing and air drying.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a water-based flux cleaning agent and a preparation method thereof. Background technique [0002] In manufacturing industries such as electronics, instrumentation, and machinery, the cleaning effect of flux is a key process that affects product quality. At present, flux cleaning agents are mostly prepared with fluorocarbon solvents and halogenated hydrocarbon solvents. Such cleaning agents contain carcinogens. Direct contact with the human body is likely to cause skin cancer, and the cost is high and it causes serious pollution to the environment. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a water-based flux cleaning agent, the water-based flux cleaning agent raw materials are cheap and easy to obtain, environmentally friendly and non-toxic, and can decompo...
