Environment-friendly and safe cleaning agent for surface of die-casting aluminum workpiece and preparation method of cleaning agent

Abstract

The invention relates to the field of industrial cleaning agents, in particular to an environment-friendly and safe cleaning agent for the surface of a die-casting aluminum workpiece and a preparation method of the environment-friendly and safe cleaning agent, and aims at solving the problems that a traditional cleaning agent often has the defects of environmental pollution and harm to a human body, and metal rust is caused by water-based cleaning. According to the preparation method, deionized water is used as a solvent, a modified surfactant is added into the solvent, the modified surfactant has the effects of wetting, dissolving, decontaminating, emulsifying grease and foaming to reduce surface tension, the function of removing greasy dirt is achieved, the modified surfactant has excellent biodegradability, a layer of hydrophobic protective film can be formed on the metal surface by adding a modified corrosion inhibitor, and the metal surface is protected. And cerium chloride heptahydrate, propylene glycol butyl ether and butyl ether are added for compounding, so that the oil stain removal and corrosion prevention effects of the modified surfactant and the modified corrosion inhibitor are enhanced.
