Abstract

The invention discloses an oil stain cleaning agent for non-ferrous metals and a preparation method thereof, the oil stain cleaning agent comprises a surfactant, an auxiliary agent, a chelating agent, a defoaming agent, a corrosion inhibitor, N-lauroyl phenylalanine, tribasic acid, an additive and the like, the surfactant comprises a nonionic surfactant and an anionic surfactant, and the surfactant comprises a nonionic surfactant and an anionic surfactant. The nonionic surfactant is any one or a mixture of coconut oil fatty acid diethanolamide and fatty alcohol-polyoxyethylene ether; according to the oil stain cleaning agent for the non-ferrous metals and the preparation method of the oil stain cleaning agent, the process design is reasonable, operation is easy, the prepared oil stain cleaning agent is high in cleaning rate and excellent in cleaning effect, and the cleaning agent has excellent anti-rust property and antibacterial property, can be applied to cleaning of the non-ferrous metals and medical metals, is longer in preservation time, not prone to mildewing and good in cleaning effect. And the practicability is high.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to an oily cleaning agent for non-ferrous metals and a preparation method thereof. Background technique [0002] In the maintenance and repair of machining and mechanical equipment, automobiles, etc., diesel, kerosene or gasoline are mostly used as cleaning fluids to clean parts. This is not only a waste of energy, but also has potential unsafe factors. A little carelessness may cause a fire. Therefore, metal cleaning agents have become a research hotspot and gradually entered our lives. [0003] The so-called metal cleaning is to put metal products with certain pollutants into a specific solvent, and then remove the metal surface pollutants through technological methods, so that the products meet the use standards. The cleaning agent used must not cause corrosion or damage to the metal; the existing metal cleaning agents include organic solvent-based cleaning agents, water...
