Problems solved by technology

[0002] In the maintenance and repair of machining, mechanical equipment, automobiles, etc., diesel oil, kerosene or gasoline are mostly used as cleaning fluids to clean parts, but because this cleaning method is not only costly, wastes energy, but also has potential unsafe Factors, if you are not careful, it may cause a fire. Therefore, based on the consideration of cost and use safety, in recent years, metal cleaning agents have gradually entered our lives and have been widely used. It can well replace diesel and kerosene. and gasoline to clean parts, and the price is cheap, safe to use, very suitable for mechanized cleaning operations
[0003] Nowadays, the metal surface cleaning agents commonly used in the market have a relatively single function, and can only clean non-ferrous metals or ferrous metals. The cleaning efficiency is low, and the metal cleaning agents contain phosphate substances, which cause serious environmental pollution.

Abstract

The invention discloses a high-cleanliness environmentally-friendly metal surface oil dirt cleaning agent and a preparation method thereof. The high-cleanliness environmentally-friendly metal surfaceoil dirt cleaning agent comprises a surfactant A, a surfactant B, a nonionic surfactant, an aid A, an aid B, a corrosion inhibitor and the like. During preparation of the surfactant A, an intermediatecashew phenolchloroether is synthesized by taking anacardol and epoxy chloropropane as raw materials and tetrabutylammonium bromide as a catalyst and then reacts with dimethylamine to generate tertiary amine, and finally 3-chlorine-2-sodium hydroxypropionic acid is added to generate a quaternary ammonium salt cashew phenol betaine type surfactant. The invention discloses the high-cleanliness environmentally-friendly metal surface oil dirt cleaning agent and the preparation method thereof. The process design is reasonable and the component proportion is proper. The cleaning agent has excellentmetal oil dirt removing effect, has a certain anti-rust property and corrosion resistance on the metal surface, can be applied to mixed cleaning of ferrous metal, nonferrous metal and rare metal, andhas high practicability.
