Problems solved by technology

[0005] In the prior art, water-based metal cleaning agents are often mainly based on wax and oil removal, and the effect on metal ions (such as copper ions, iron ions) and subsequent anti-corrosion treatment on the metal surface is not obvious, and the dispersion is unstable, resulting in poor cleaning. Thoroughly, in order to solve the above problems, complexing agents and penetrating agents are often added to the cleaning agent to achieve the effect of adsorbing metal ions, but on the one hand, the effect is not obvious, on the other hand, the formula is complicated and the cost is high

Abstract

The invention relates to a metal cleaning agent, and discloses a metal cleaning agent added with functional modified graphene and a preparing method of the metal cleaning agent. The metal cleaning agent is composed of 4-15wt% of triethanolamine functional graphene, 13-25wt% of surfactant, 1-2wt% of metal corrosion inhibitor, 0.1-0.8wt% preservative and the balance water. According to the metal cleaning agent, the triethanolamine functional graphene is creatively used to be added into the metal cleaning agent, triethanolamine of the triethanolamine functional graphene and the graphene are bonded as covalent bond, and the surface of the metal cleaning agent contains a large amount of tertiary amine nitrogen and hydroxyl active functional groups; and amino ionic liquid functional graphene achieves graphene modification through the non-covalent interaction between imidazole rings and graphite rings, the graphene has the super large specific surface area, the strong complexing effect is achieved after the grapheme and the triethanolamine are functionalized, so that the strong adsorption capacity is achieved, the hydrophilic and lipophilicity of the triethanolamine are retained, the strong adsorption capacity also can be achieved, and the metal cleaning agent is used without matching of an additional complexing agent.

Description

technical field [0001] The invention relates to a metal cleaning agent, more specifically, to a metal cleaning agent added with functionalized modified graphene 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...
