Aluminum-magnesium alloy wiredrawing lubricant

Abstract

The invention provides an aluminum-magnesium alloy drawing lubricant which consists of the components with the following mass percentage: 85 to 94 percent of base oil, 3 to 8 percent of polyurethane,1 to 2 percent of antirust agent CY-25, and 2 to 5 percent of water-soluble molybdenum. The base oil is animal grease or plant grease with the movement viscosity of 15 to 30mm2 / s used when the temperature of the lubricant is 50 DEG C. The invention has the advantages that: the invention replaces chloride series and sulfur series extreme-pressure additive with the polyurethane, greatly decreases the content of chloride, sulfur and phosphorus in a product, reduces the treatment cost of waste oil, increases the environmental protection, is not easy to catch fire, has good lubrication performance;allows the proportion of the composition to be optimized; the product has extremely low unsaturation degree, no pollution to metals, excellent thermal stability, oxidation stability and hydrolytic stability, slows the aging and prolongs the service life.

(1) Technical field [0001] The invention relates to an aluminum-magnesium alloy wire drawing lubricant. (2) Background technology [0002] In the production process of aluminum-magnesium alloy round wire drawing, a large amount of lubricant (that is, drawing oil) is used, while the existing aluminum-magnesium alloy round wire drawing oil generally uses chlorine-based, sulfur-based and phosphorus-based extreme pressure additives. The content of sulfur and phosphorus is large, easy to catch fire and has poor lubricating performance. Therefore, most manufacturers use copper wire drawing oil or aluminum wire drawing oil instead, but aluminum or copper wire drawing oil is expensive, so some manufacturers use engine oil and diesel oil as wire drawing oil. .

[0002] In the production process of aluminum-magnesium alloy round wire drawing, a large amount of lubricant (that is, drawing oil) is used, while the existing aluminum-magnesium alloy round wire drawing oil generally uses chlorine-based, sulfur-based and phosphorus-based extreme pressure additives. The content of sulfur and phosphorus is large, easy to catch fire and has poor lubricating performance. Therefore, most manufacturers use copper wire drawing oil or aluminum wire drawing oil instead, but aluminum or copper wire drawing oil is expensive, so some manufacturers use engine oil and diesel oil as wire drawing oil.

Using machine oil as drawing oil has poor lubricity, cooling and oxidation resistance, especially in the high-speed drawing process, which cannot meet the needs of lubrication, and the oil has poor oxidation resistance and short service life.

However, diesel oil is used as drawing oil, although the cost is low and the cleaning performance is good, but due to the low flash point of diesel oil, it is prone to fire and brings catastrophic losses to the manufacturer.
