Abstract

The invention discloses a metal cleaning agent and a preparation method thereof and belongs to the field of chemical engineering. The metal cleaning agent comprises the following components, by weight, 12-15.6% of alkyltrimethylammonium chloride, 1.8-3.2% of lauroyl diethanolamide, 4-8% of sodium polyoxyethylene ether sulfate, 1-5% of fatty amine polyoxyethylene ether, 2-4% of lauryl sodium sulfate, 7-10% of dodecyl dimethyl betaine, 1.1-1.9% of sodium oleate, 0.1-1.5% of a preservative, 6-10% of triethanolamine, 1-3% of sodium gluconate, 5-12% of glycerol and the balanced being deionized water. The metal cleaning agent is prepared by compounding various surfactants, has excellent cleaning performance at room temperature, is phosphorus-free and is green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a metal cleaning agent and a preparation method thereof. Background technique [0002] Metal cleaning agents are widely used in industrial production, and are often used for surface degreasing and descaling before and after metal processing, as well as cleaning processes before assembly or packaging of finished products. In the electronics industry, cleaning agents must also be used to remove harmful residues after soldering printed circuit boards. In addition, metal cleaning agents are often used in the maintenance process of mechanical equipment. [0003] At present, the commonly used metal cleaning agents are divided into solvent type, semi-solvent type and water-based type. Among solvent-based metal cleaners, petroleum solvents are flammable, explosive, and a waste of resources. Chlorofluorocarbons are the most commonly used solvent-based metal cleaners, but are ...
