Problems solved by technology

[0003] 1. Poor lubricating film adsorption
The lubricating film formed on the surface of the drawn workpiece and the mold is unstable, and is easily squeezed out during the extrusion and stretching process, which directly affects the lubrication effect, not only sharply reduces the surface finish and brightness of the drawn workpiece, but also intensifies the The wear and tear on the mold will affect the service life of the mold;
[0004] 2. The cooling effect is not ideal
The lubricating effect is not good due to the poor adsorption of the lubricating film. Therefore, although the cooling effect is improved compared with oil-based lubricants, the quality problems of broken wires due to local overheating often occur;
[0005] 3. The lubricating coolant for fine drawing of various copper alloy wires (brass wire, aluminum bronze wire, etc.) cannot be used universally. When drawing multiple copper alloys at the same time, different lubricating coolants are required, which increases the cumbersome production operations characteristics and inventory costs of manufacturers;
[0006] 4. Higher requirements for dilution water quality, such as diluting with hard water, will have a greater impact on the stability of the lubricating cooling emulsifier;
[0007] 5. It is easy to deteriorate, especially in summer with high temperature, it will produce foul smell, which will affect the health of operators

Abstract

A fine pulling lube cooling emulsified oil of copper alloy consists of motor oil 56-60wt%, oleic acid 8-12wt%, mersolates 8-12wt%, zinc naphthenate 4-6wt%, triethyl phosphate 8-10wt%, anhydrous alcohol 1-2wt%, dibutyl phthalate 1-3wt%, non-ionic surface activator 3-6wt% and benamide azole trinitride 0.5-1wt%. The process is carried out by putting motor oil into reactor, heating to 60-70degree, adding mersolates, zinc naphthenate, triethyl phosphate, dibutyl phthalate and oleic acid into motor oil successively, agitating at 600-650 / min for 1-2hrs, dissolving benamide azole trinitride by anhydrous alcohol, adding into mixed solution, adding into non-ionic surface activator, agitating and lowering temperature. It can prevent pulling metal from overheat and oxidation coloring and have better finish degree and brightness.

Description

Technical field: [0001] The invention relates to a lubricating cooling liquid for drawing process and its production method, especially a kind of fine drawing lubrication for copper alloy wire which can prevent partial overheating of drawn metal, oxidative discoloration and ensure the surface finish and high brightness of the finished product. Cooling emulsified oil and production method. Background technique: [0002] The drawing process is a typical metal processing method. It is a plastic processing process that reduces the cross-sectional area of ​​the metal processing material through the die hole core under the action of drawing to obtain a high-precision, high-gloss wire or pipe. During the drawing process, due to the large amount of metal deformation and the continuous generation of new friction surfaces, lubricating coolant is required to lubricate and cool the metal material and mold. In particular, the fine drawing process generally draws a rough material with a ...
