Embodiment 1

[0039] One, the preparation film-forming agent is acrylic acid-polyurethane emulsion, and its preparation process is:

[0040] A. Synthesis of core-shell hydroxyacrylic acid emulsion by seed method: Add core raw materials methyl methacrylate, butyl acrylate, and acrylic acid in sequence in the container, with a mass ratio of 1:1.1:2.3, heat up to 80°C, and add the first core layer The monomer was kept warm for 35 minutes to obtain the seed emulsion of the core layer. The duration of dropping the second core layer monomer was 1.2 hours. The mixed solution of toluene diisocyanate trimer, polyethylene glycol monomethyl ether and polyether, its mass ratio is 1:1.2:1.7:1.8, keep warm for 1.9h after the dropwise addition, and adjust the pH value of the emulsion after cooling down to room temperature Between 7.5, filter to obtain a core-shell type hydroxyacrylic acid emulsion; the mass ratio of the core material, the first core layer monomer, the second core layer monomer and the she...

[0053] One, the preparation film-forming agent is acrylic acid-polyurethane emulsion, and its preparation process is:

[0054] A. Synthesis of core-shell hydroxyacrylic acid emulsion by seed method: Add core raw materials methyl methacrylate, butyl acrylate, and acrylic acid in sequence in the container, with a mass ratio of 1:1:2.5, raise the temperature to 78°C, and add the first core layer The monomer was kept warm for 40 minutes to obtain the seed emulsion of the core layer. The duration of dropping the second core layer monomer was 1 hour. The mixed solution of isocyanate trimer, polyethylene glycol monomethyl ether and polyether has a mass ratio of 1:1:1.8:1.5. After the dropwise addition, keep it warm for 1.8 hours. After cooling down to room temperature, adjust the pH value of the emulsion to 8.0 or less. Between, filter to obtain the core-shell type hydroxyacrylic acid emulsion; the mass ratio of the core raw material, the first core layer monomer, the second core lay...

Abstract

The invention relates to the technical field of metal forming and processing, and discloses a high-fluidity lubricant for metal drawing and application of the lubricant, aiming at solving the problemsof poor film-forming property and poor fluidity of a metal drawing lubricant in the prior art. The cutting fluid comprises the following components in percentage by weight: 60-65% of natural fatty acid salt, 2-4% of extreme pressure agent, 1-3% of antirust agent, 0.5-1% of chelating agent, 0.1-1% of preservative, 0.5-1% of surfactant and 3-5% of film-forming agent, and the balanced being water. The invention discloses a newly developed environment-friendly low-consumption lubricant for steel pipe drawing, which has favorable lubricating property, higher flowability and film-forming property,can better adapt to high-speed drawing and isolate air, achieves favorable antirust action and friction reduction action, and is simple in processing procedure.

Description

technical field [0001] The invention relates to the technical field of metal forming, in particular to a lubricant for metal drawing with high fluidity and its application. Background technique [0002] Metal drawing is a plastic processing technology that reduces the cross-sectional area of ​​the processed material through the die hole and obtains high-precision, high-gloss wire or pipe. It is widely used in processing carbon steel, stainless steel, alloy steel, copper, aluminum and other materials. Alloys and other metal materials. Usually, most of the energy consumed in the drawing process is consumed in the friction between the mold and the drawing material, causing the temperature of the interface to rise, and the lubricating film is prone to rupture or even sintering. During this process, a good lubrication state can reduce the heat generated by friction during drawing, which helps to prolong the life of the die, increase the drawing speed and improve the surface qual...
