Environmentally-friendly nano water soluble non-oil lubricant used for cold rolling metals and its preparation method

Abstract

The invention relates to an environmentally-friendly nano water soluble non-oil lubricant used for cold rolling metals and its preparation method, which is characterized by comprising the following components by mass percentages: 15% of dimer acid, 40% of diammonium hydrogen phosphate, 20% of oleic acid alkanolamide, 8% of tween80, 15% of lauryl alcohol and 2% of surface modified nano-magnetite. According to the invention, a nano technology is used for preparing the lubricant which realizes the requirement of the current civilized production with low energy consumption, low pollution, low discharge and high environmental protection, and the lubricant of the invention has the characteristics of high temperature resistance and is capable of increasing the wear resistance and prolonging the service life of a roller. The lubricant of the invention is a product with smoke-free, odorless, notoxcity, harmlessness. According to the detection of toxicology department of Shenyang labor hygiene occupational disease institute and Qingdao national dangerous material detection center, LD50 is greater than 10000milligram / kg, fish and shrimp can be survived and reproduced in aqueous solution of 0.1% of the product.

Description

Technical field [0001] The present invention is a processing agent for metallurgical industry cold -rolled bands, pipes, and wires, which involves a kind of environmentally friendly nano -water -soluble non -oil metal cold -rolling agent and preparation method. Background technique [0002] When metal is carried out cold rolling agents, lubricants usually use to reduce friction between metal and rolls, reduce the wear of rolls, and promote good surface cleanliness on the surface of the metal by lubricant. The lubricant used in cold rolling can also be used as cooling.The role.The traditional use rolling lubricant is oil or emulsified oil, which has a history of more than 100 years. This lubricant exists: 1. It cannot meet the needs of large -scale and high -speed and high -speed and high -speed needs of modernized rolling machines; 2. Waste a large amount of energy; 3.The amount of waste liquid is large and difficult to deal with; 4. The operation environment is harsh, and the sm...

Problems solved by technology

The traditionally used rolling lubricant is oil or emulsified oil, which has a history of more than 100 years. This kind of lubricant exists: 1. It cannot meet the needs of large-scale and high-speed modern rolling mills; 2. Waste a lot of energy; 3. The amount of waste liquid is large and extremely difficult to handle; 4. The operating environment is harsh, and the smoke is toxic and affects the health of workers; 5. The waste liquid and gas seriously damage the ecological environment; 6. The surface quality of the rolled material is poor and other problems
