Embodiment 1

[0025] The raw materials of a lubricant used for drawing ultra-fine stainless steel wire are proportioned in parts by weight as follows:

[0026] 5 parts of polyethylene glycol (molecular weight 6000), 8 parts of isopropanol, 1 part of sulfurized isobutylene, 5 parts of lauryl dihydroxyethylamine oxide, 0.5 parts of polyaspartic acid, 1 part of triethanolamine oleate, 55 parts of water share.

[0027] The specific preparation method is as follows: first add water to the reaction kettle, and add the formula amount of polyethylene glycol, raise the temperature to 60~70°C until it is completely dissolved; then continue to raise the temperature and keep it at 90~100°C, under the condition of constant stirring Next, add sulfurized isobutylene, lauryl dihydroxyethyl amine oxide, and triethanolamine oleate in sequence, stir evenly, and cool down naturally; cool down to 50~60°C, add polyaspartic acid, isopropanol, and stir Evenly, cool to room temperature; put the obtained paste into...

Embodiment 2

[0030] The raw materials of a lubricant used for drawing ultra-fine stainless steel wire are proportioned in parts by weight as follows:

[0031] 10 parts of polyethylene glycol (molecular weight 5000), 5 parts of isopropanol, 0.5 part of sulfurized isobutylene, 10 parts of octadecyl dihydroxyethyl amine oxide, 0.5 part of polyaspartic acid, 0.5 part of triethanolamine oleate, 60 parts of water.

[0032] The preparation method and usage method are the same as in Example 1.

Abstract

The invention relates to lubricant for drawing a superfine stainless steel wire, which is characterized in that the lubricant is prepared by water, polyethylene glycol, isopropanol, extreme-pressure additive, amine oxide, polyaspartic acid and metal rust-proof agent, wherein the proportion in part by weight of each substance in the lubricant is as follows: 5 to 10 parts of polyethylene glycol, 5 to 10 parts of isopropanol, 0.5 to 2 parts of extreme-pressure additive, 5 to 20 parts of amine oxide, 0.5 part of polyaspartic acid, 0.5 to 1 part of metal rust-proof agent and 45 to 100 parts of water. By utilizing the lubricant, good lubricating performance can be maintained when the superfine stainless steel wire is drawn, the surface quality of the superfine stainless steel wire can be improved, the superfine stainless steel wire can be uniformly drawn, the surface of the superfine stainless steel wire is bright and uneasy to rust, and the wire breaking rate can be reduced.

Description

technical field [0001] The invention relates to a lubricating medium, in particular to a lubricating coolant suitable for drawing ultra-fine stainless steel wires and a preparation method thereof. Background technique [0002] Wire drawing is a metal plastic processing process that pulls the wire rod or wire blank from the die hole of the wire drawing die under the action of the drawing force to produce small-section steel wire or non-ferrous metal wire. According to the temperature of the metal during drawing, drawing below the recrystallization temperature is cold drawing, drawing above the recrystallization temperature is hot drawing, and drawing above room temperature and below the recrystallization temperature is warm drawing. Cold drawing is the most common drawing method used in wire and wire production. Lubricants are used in the wire drawing process to form a lubricating film between the drawn metal and the wire drawing die wall to reduce energy consumption and tem...
