Problems solved by technology

[0002] The copper wire drawing production process is used in the wire and cable industry. In order to make it efficiently produced, lubricants must be used. However, in actual production, some problems often occur: during the drawing process of copper ultra-fine wire, the copper wire is prone to oxidation; Copper ions in the lubricant react with anions to form copper soaps, and these copper soaps precipitate and block the die holes of the wire drawing die, causing the lubricant to fail to pass through the die holes with the copper wires and fail to adhere to the surface of the copper wires, resulting in lubrication failure

Abstract

The invention discloses a lubricating agent for superfine copper wire drawing. The lubricating agent comprises the following components in parts by mass: 5-25 parts of lubrication base oil, 10-30 parts of an emulsifying agent, 1-5 parts of a surface active agent, 1-10 parts of an antirust agent, 1-5 parts of an extreme pressure antiwear additive, 1-5 parts of a thickening agent, 5-25 parts of an alkali retention agent, 1-5 parts of a bactericide, 0.1 part of a defoaming agent and 30-50 parts of water. The lubricating agent for superfine copper wire drawing has good oxidation resisting, cooling, cleaning, lubricating, rust preventing, hard water resisting and copper soap dispersing properties, and is particularly suitable for superfine copper wire drawing.

Description

technical field [0001] The invention relates to a lubricant for ultrafine copper wire drawing, which belongs to the technical field of molds. Background technique [0002] The copper wire drawing production process is used in the wire and cable industry. In order to make it efficiently produced, lubricants must be used. However, in actual production, some problems often occur: during the drawing process of copper ultra-fine wire, the copper wire is prone to oxidation; Copper ions in the lubricant react with anions to form copper soaps, and these copper soaps precipitate and block the die holes of the wire drawing die, causing the lubricant to fail to pass through the die holes with the copper wires and fail to adhere to the surface of the copper wires, resulting in lubrication failure. [0003] The high-speed wire drawing production line developed in recent years puts forward higher requirements for lubricants, such as requiring suitable lubricity to reduce wear and improve ...
