Example Embodiment
[0020] Example 1: A wire drawing lubricant for free-cutting steel, which is composed of the following raw materials in weight percentage: 65% lubricant, 3% friction reducing agent, 2% extreme pressure agent, 5% rust inhibitor, The combined dosage is 25% sodium hydroxide and potassium hydroxide; the sum of the weight percentages of the lubricant, friction reducer, extreme pressure agent, rust inhibitor, sodium hydroxide and potassium hydroxide is 100%;
[0021] Among them: the lubricant is one or more of gum rosin, capric acid, palmitic acid, monoglyceride, capric acid, stearic acid, and lauryl alcohol; the friction reducing agent is polyethylene wax, bentonite, One or more of sulfur powder, citric acid, barium stearate, and talc; the extreme pressure agent is one or more of tungsten disulfide, phosphite, boron nitride, and sodium metaborate. The rust inhibitor is one or more of sodium molybdate, sodium chromate, sodium nitrite, barium dinonylnaphthalenesulfonate, and oxidized pet...
Example Embodiment
[0023] Example 2: A wire drawing lubricant for free-cutting steel, which is composed of the following raw materials in weight percentages: 43% lubricant, 20% friction reducing agent, 12% extreme pressure agent, 5% rust inhibitor, The comprehensive dosage is 20% sodium hydroxide and potassium hydroxide; the sum of the weight percentages of the lubricant, friction reducing agent, extreme pressure agent, rust inhibitor, sodium hydroxide and potassium hydroxide is 100%.
[0024] The preparation method of the wire drawing lubricant for free-cutting steel of the present invention is: adding gum rosin, stearic acid, monoglyceride, polyethylene wax, capric acid and dodecane in a container equipped with a stirring and heating device. Alcohol, barium dinonylnaphthalene sulfonate, heat to about 80℃, then add sodium hydroxide or potassium hydroxide, dilute with water to 30% content, keep for 30 minutes, add bentonite, barium stearate, two Tungsten sulfide, sodium metaborate, sodium molybdate...
