Abstract

The invention discloses an ultrasonic cleaning agent which comprises the following components: sodium dodecyl benzene sulfonate, calcium dodecyl benzene sulfonate, dodecyl dimethyl benzyl ammonium chloride, magnesium stearate, cetyltrimethylammonium chloride, disodium EDTA (Ethylene Diamine Tetraacetic Acid), polyacrylamide, NaOH, NH3, H2O, NH4Cl and an organic solvent. Aiming at the characteristics of shell of electronic products, for the ultrasonic cleaning agent disclosed by the invention, cetyltrimethylammonium chloride is added to remove negative charges on the surface of the shell. The three anionic surfactants sodium dodecyl benzene sulfonate, calcium dodecyl benzene sulfonate, dodecyl dimethyl benzyl ammonium chloride can effectively remove dirt carried by the shells of the electronic products, and magnesium stearate is used as a supplement for the three anionic surfactants so as to thoroughly clean various dirt on the shells of the products. Meanwhile, various medicaments provided by the invention have the characteristics of easiness in recovery, low toxicity, easiness in treatment and the like, so that the damage to the environment and human body in the production process is reduced.

Description

Technical field [0001] The invention relates to the technical field of surface cleaning, in particular to an ultrasonic cleaning agent and an ultrasonic cleaning method. Background technique [0002] After the shell of an electronic product is injection molded, its surface is usually contaminated with dust, oil and other complex dirt due to static electricity. The above-mentioned dirt must be cleaned before the shell can be surface treated and other subsequent processes. With the development of miniaturization and multifunctionalization of electronic products, the structure of electronic product housings has become more and more complex, usually with a large number of small pores, which brings difficulties to cleaning. In order to achieve the purpose of completely removing dirt on the surface of the shell, the existing method is to spray the shell with a chemical agent to remove most of the dirt and then soak the shell in the chemical water for ultrasonic cleaning, thereby removi...
