Water-based metal cleaning agent

Abstract

The invention provides a water-based metal cleaning agent. The water-based metal cleaning agent comprises, by mass, 1-5 parts of sodium dodecyl benzene sulfonate, 5-15 parts of potassium hydrogen persulfate, 1-5 parts of sodium mono-and di-decyl disulfonated diphenyl oxide, 1-3 parts of trisodium citrate and the balance water used for supplementation, and the number of total mass parts is 100. Compared with the prior art, component matching of the water-based metal cleaning agent is reasonable, an organic solvent, the strong base and the phosphorus element are not contained in raw materials, and the water-based metal cleaning agent is environment-friendly. In addition, the source of the raw materials is wide, cost is low, a very good dirt and oil removing effect is achieved, especially, the cost is lower than that of market sold classic products by 75% or above, and great market competitive advantages are created for enterprises.

Description

technical field [0001] The invention relates to the field of water-based cleaning agents, in particular to a water-based metal cleaning agent for cleaning stains and oil stains on the surface of precision metal parts. Background technique [0002] The development of metal cleaning agents began in the last century. With the different cleaning environments, cleaning objects and the strengthening of people's environmental protection concepts, the original metal cleaning agents were gradually replaced, from the initial solvent-based cleaning agents to water-based cleaning. Agent transition, from suitable for cleaning in acidic environment to gradually transition to neutral or weakly alkaline environment. At present, water-based metal cleaning agents still have the following problems to be solved: 1) Water-based cleaning agents have a certain degreasing power for cleaning workpieces with flat surface structures, but for workpieces with complex structures, there are certain cleani...

Problems solved by technology

At present, water-based metal cleaning agents still have the following problems to be solved: 1) Water-based cleaning agents have a certain degreasing power for cleaning workpieces with flat surface structures, but for workpieces with complex structures, there are certain cleaning blind spots , such as residues attached to the deep holes and gaps of the workpiece, which also indirectly lead to an increase in subsequent processes and increased production costs; 2) The cleaning temperature of water-based cleaning agents generally needs to be heated to have a better effect, but in In some low-temperature areas, the degreasing speed is slow, and it is difficult to compare with the cleaning effect of solvent-based cleaning agents; 3) After the water-based cleaning agent is cleaned, the metal parts of the workpiece, such as steel mesh, cast iron and component pins If it is not dried in time, it is easy to be oxidized, rusted and corroded again; 4) The waste liquid after cleaning contains a large amount of phosphorus in the water-based cleaning agent, so it is difficult to follow up and recycle; 5) The raw material of the water-based cleaning agent Complex composition and high production cost
