Description

Technical Field

[0001] The invention belongs to the technical field of copper processing auxiliary materials, and in particular relates to a clean copper wire drawing liquid composite agent and a preparation method thereof. Background Art

[0002] In the copper processing industry, the copper wire drawing process is a key step in producing various types of copper wire. As an indispensable auxiliary material in this process, the performance of copper wire drawing liquid directly affects the smooth progress of production and the quality of the copper wire. However, the copper wire drawing liquid used in the prior art often exhibits soap precipitation during use.

[0003] The main cause of soap formation is the improper combination of lubricants, surfactants, and other ingredients used in existing wire drawing fluids. Under the high-temperature, high-pressure conditions of wire drawing production, chemical reactions easily produce soaps. These soaps combine with the copper sludge generated during processing, resulting in large amounts of adhesion to the inside of the machine and the surface of the mold.

[0004] This phenomenon presents numerous serious hazards. First, the interior of the machine and molds become clogged with copper sludge, increasing the cleaning workload during production and requiring frequent machine downtime for cleaning, severely impacting production efficiency. Second, the adhesion of copper sludge and soap substances alters the mold's dimensions and surface roughness, leading to uneven friction between the copper wire and the mold during the drawing process. This, in turn, affects the copper wire's surface gloss and precision, reducing product quality. Summary of the Invention

[0005] The purpose of the present invention is to provide a clean copper drawing liquid composite and a preparation method thereof, aiming to solve the technical problem that in the prior art, copper drawing liquid often undergoes soap precipitation during use, causing the inside of the machine and the mold to be covered with copper mud, increasing the cleaning workload during the production process, requiring frequent shutdowns for cleaning, seriously affecting production efficiency, and causing uneven friction between the copper wire and the mold during the drawing process, thereby affecting the surface gloss and precision of the copper wire and reducing product quality.
