Problems solved by technology

[0003] At present, the domestic research on cleaning agents for copper parts is roughly divided into alkaline cleaning agents and acid cleaning agents. More applications are mainly strong acid cleaning agents based on industrial tri-acids. It is easy to corrode workpieces, and strong acid cleaning agents are more harmful to the health of on-site operators. Therefore, it is an urgent technical problem to provide a cleaning agent that is less corrosive, more healthy and environmentally friendly, and has a better cleaning effect.

Abstract

The invention provides a red copper rolling cleaning agent and a production method thereof. Raw materials of the cleaning agent comprise, on the basis of a 100% mass percentage, 10-20% of a surfactant, 5-20% of an anti-rust agent, 0.1-2% of a non-ferrous metal corrosion inhibitor, 5-20% of a builder, 5-15% of an anti-redeposition agent, 5-15% of an organic acid and the balance water. The production method comprises the steps of putting the anti-rust agent, the non-ferrous metal corrosion inhibitor and the anti-redeposition agent into the water at first, after heating and stirring are conducteduntil the anti-rust agent, the non-ferrous metal corrosion inhibitor and the anti-redeposition are dissolved, conducting cooling, then sequentially putting the surfactant, the builder and the organicacid, and conducting stirring until an obtained mixture is transparent to obtain the red copper rolling cleaning agent. The raw materials adopted for the red copper rolling cleaning agent are environmentally friendly, and the red copper rolling cleaning agent has low corrosiveness to metal, is more friendly to production people, has excellent cleaning performance at the same time, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning agent for red copper rolling and a preparation method thereof. Background technique [0002] Copper is widely used in generators, cables, transformers and other electrical equipment and heat exchangers. At present, the demand for red copper in the market is growing day by day, and the quality requirements for red copper products are becoming more and more stringent. In the red copper rolling production, rolling oil is generally used to ensure the production quality, and the rolled copper surface will have rolling oil residue or Dust, if not cleaned in time, will affect the follow-up process and product surface quality, so it is necessary to clean the surface of copper parts. [0003] At present, the domestic research on cleaning agents for copper parts is roughly divided into alkaline cleaning agents and acid cleaning agents. More applications are mainly stron...
