High-efficiency copper wire drawing liquid with long usage life and preparation method thereof

Abstract

The invention discloses a high-efficiency copper wire drawing liquid with long usage life, which is characterized by comprising the following raw materials by weight: 4-6 parts of polyoxyethylene alkanolamide, 2.5-4 parts of dimethyl acetamide, 4-5 parts of liquid paraffin, 2-3 parts of eleaostearic acid, 3.5-4.5 parts of deionized water-soluble phosphate ester, 1-2 parts of sodium benzoate, 2.5-3.5 parts of triethanolamine oleate, 1-2 parts of DL602 Casson antiseptic, 8-10 parts of silicon powder, 5-7 parts of auxiliary agent and 900-950 parts of deionized water. According to the invention, the added sodium benzoate and the DL602 Casson antiseptic have good anticorrosion effect, and odor and blackening condition of the wire drawing liquid can not be easily generated, and the added auxiliary agent has good antiwear, dispersion, lubrication and film forming ability. The high-efficiency copper wire drawing liquid has excellent lubrication performance, can satisfy the requirement of client brightness and size precision under low concentration, water base has good heat radiation effect, and the high-efficiency copper wire drawing liquid has the advantages of easy preservation and long usage life, and is suitable for copper wire drawing.

Description

technical field [0001] The invention relates to the technical field of wire drawing, in particular to a high-efficiency copper wire drawing liquid with long service life and a preparation method thereof. Background technique [0002] Copper wire (wire) is the main transmission wire for power transmission in the power industry. It is usually made by drawing process, that is, copper wire with large diameter such as steel wire passes through the hole of the mold, and is pulled under the action of external force to reduce the cross-sectional area to form the required diameter. of wire. In the copper wire drawing process of my country's cable industry, copper and enameled wire industry, there are generally oxidative discoloration and blackening, which are more serious in spring and summer. With the popularity of existing high-speed machines, the drawing speed has been greatly improved, and the contradictions have become more and more prominent. There are many kinds of lubricant...

Problems solved by technology

There are many kinds of lubricants used for copper wire drawing, and the performance varies greatly. Some wire drawing lubricants will turn black and smelly during use.

There are also some copper wire drawing lubricants that have adverse conditions such as increased tensile force, increased friction, increased oil temperature, increased oil consumption, fast loss of molds and tower wheels, and increased copper powder, which will cause the surface quality of the drawn wire to decrease, which is serious. It affects the quality of the drawn copper wire, so in order to improve the quality of the wire and save costs, it is particularly important to choose and use copper wire drawing lubricants reasonably
