AI Technical Summary

Problems solved by technology

[0004] (1) Traditional water-based cleaning agents have certain cleaning blind spots for workpieces with complex structures, such as the residues attached to the deep holes and gaps of the workpiece cannot be cleaned well;
[0005] (2) There are many residues after cleaning with traditional water-based cleaning agents, which cause great environmental pollution and high processing costs;
[0006] (3) Traditional water-based cleaning agents clean the metal parts of steel and cast iron workpieces, which are easier to oxidize, rust or corrode

Abstract

The invention discloses a water-based metal cleaning agent, which is made of the following raw materials in parts by mass: 3-8 parts of anionic surfactant, 1-10 parts of non-ionic surfactant A, 1-10 parts of non-ionic surfactant Ionic surfactant B, 2~5 parts of dispersant, 1.5~2.2 parts of complexing aid, 10~20 parts of silicate, 3~10 parts of inorganic base, 2~5 parts of organic base, 0.1 ~0.5 parts of defoamer, 37.3~76.4 parts of water. The invention also discloses a method for preparing the water-based metal cleaning agent. The invention has the advantages of good cleaning effect, no blind area in cleaning, less residue after cleaning, and less corrosion to metal workpieces after cleaning.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a water-based metal cleaning agent and a preparation method thereof. Background technique [0002] With the rapid development of the metal processing industry, the continuous improvement of cleaning quality requirements, the continuous increase of cleaning objects, and the continuous enhancement of people's environmental protection concepts, the original powder-based and solvent-based metal cleaning agents are gradually replaced by liquid water-based cleaning agents. In consideration of environmental protection and safety, the cleaning agent gradually transitions from an acidic cleaning agent to a neutral or weakly alkaline product. [0003] At present, the water-based metal cleaner has the following problems: [0004] (1) Traditional water-based cleaning agents have certain cleaning blind spots for workpieces with complex structures, such as the residues attached to the...
