Abstract

The invention discloses a water-based metal cleaner and a preparation method thereof. The water-based metal cleaner is prepared from sodium dodecylbenzene sulfonate, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, triethanolamine oleate, triethanolamine, 3-methyl-3-methoxy-1-butanol, polyphosphate, silicate, glycerol, primary sodium alkyl sulfate, isooctyl phosphate, benzotriazole, polyethylene glycol, dimethylaminoethyl methacrylate, 2-hydroyl-3-sulfopropyl starch ether and deionized water; the preparation method of the water-based metal cleaner comprises the following steps: firstly, adding a surfactant and the triethanolamine oleate to the glycerol, heating and stirring, next, adding the triethanolamine, the 3-methyl-3-methoxy-1-butanol, the polyphosphate and the silicate, adding the primary sodium alkyl sulfate, the isooctyl phosphate, the benzotriazole and the polyethylene glycol under the conditions of stirring and preserving heating, and finally adding the rest components under the conditions of stirring and preserving heating, and heating and stirring to obtain the cleaner. The water-based metal cleaner has excellent cleaning performance and relatively high corrosion inhibition period.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a water-based metal cleaning agent and a preparation method thereof. Background technique [0002] Since the quality of metal surface pretreatment directly affects the bonding force between coating or coating materials and metal base materials and the integrity of the coating, the technical requirements for metal surface pretreatment are very strict. The metal surface after painting or pre-plating treatment should meet the following requirements: (1) No oil on the surface; (2) No excess residual foreign matter; (3) No embroidery marks and oxide film; (4) The surface reaches a certain level of roughness (5) The surface is dry, free of moisture and dust; (6) The metal matrix is ​​exposed and in an activated state. [0003] The so-called metal cleaning can be simply understood as: metal products with certain dirt in a specific solvent, using a certain pr...
