Abstract

The invention discloses a preparation method for an efficient environmental-friendly rustproof water-based metal cleaning agent and belongs to the technical field of preparation of metal cleaning agents. According to the preparation method, stearic acid, oleic acid, monoethanolamine and triethanolamine generate a reaction, anionic surfactant organic amine fatty acid soap is prepared and is compouned with nonionic surfactant starch-based dodecyl glucoside, water-soluble polyol ether and a solubilizing cleaning agent are added, and all components of the water-soluble polyol ether and the solubilizing cleaning agent are capable of promoting emulsified dispersion of oil stain; and coconut oil fat diethanol amide and fatty alcohol-polyoxyethylene ether are added and serve as a hard water stabilizer, corrosion inhibitor sodium benzoate protection metal is added, washing auxiliary sodium metasilicate is added to improve the decontamination capacity and the cleaning efficiency of a surfactant, defoamer dimethyl siloxane is added after even mixing, and the efficient environmental-friendly rust-proof water-based metal cleaning agent is prepared. It is proved by the examples that the metal cleaning agent is clean and environmentally friendly, free of corrosion to metal and free of harm to the human body and the environment and has the wide future development.

Description

technical field [0001] The invention discloses a preparation method of an efficient, environment-friendly and anti-rust water-based metal cleaning agent, belonging to the technical field of metal cleaning agent preparation. Background technique [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. This not only wastes energy, but also has potential unsafe factors. If you are not careful, it may lead to a fire. In recent years, a new type of metal cleaning agent has gradually been widely used. It can replace diesel, kerosene and gasoline to clean parts, and it is cheap and safe to use. It is very suitable for mechanized cleaning operations. It can wash metal without rust spots, it is called metal cleaner. [0003] Metal cleaning agents refer to industrial cleaning agents or oil cleaning agents used to remove oil, grease, and dirt from the surface of me...
