Description

technical field [0001] The invention relates to a lubricating cooling liquid for mechanical processing and a preparation method and a using method thereof, in particular to a rolling lubricating liquid for copper threaded tubes for an air conditioner, a preparation method and a using method. Background technique [0002] Copper threaded pipes for air conditioners are high-performance, high-value-added products that emerged after the country advocated energy conservation and emission reduction. It not only maintains the excellent thermal conductivity and high temperature resistance of metal copper itself, but also has a very high heat exchange efficiency due to the formation of a tight thread structure and enlarged heat exchange surface, which can be significantly improved under the premise of obtaining the same heat exchange amount. Reduce the amount of metal copper material. [0003] Copper threaded pipe is made by multi-roll rolling process. Lubrication and cooling play a...

Problems solved by technology

[0004] In the prior art, during the rolling process of threaded copper tubes, lubricants, anti-corrosion agents and wetting components in the rolling liquid are competitively adsorbed on the surface of copper tubes, resulting in unstable lubricating ability, anti-oxidation and self-cleaning performance ;In the continuous rolling production process, it is easy to cause defects such as uneven thread density, easy oxidation, and metal powder easily stuck in the thread gap, which seriously affects the quality of the rolled pipe and increases the difficulty of cleaning in the subsequent process
