Problems solved by technology

[0002] With the development of metallurgy, ships, automobiles, aerospace and other technologies, there are more and more metal parts that need to be formed and cut, and they are getting bigger and bigger, and the precision required is getting higher and higher. Lubrication, cleaning, anti-rust and other performance requirements are getting higher and higher. Traditional lubricants and anti-rust agents are difficult to meet the high-intensity machining environment.
[0003] Lubricants currently used in metalworking fluids such as polyether (affects anti-rust), polyethylene glycol (poor lubrication), oleic acid soap (easy to stink), and Taikoo oil (easy to stink) have been difficult to satisfy High-strength machining, however, metalworking fluids require not only lubricity,

Abstract

The invention discloses an extreme-pressure metalworking liquid. The extreme-pressure metalworking liquid uses recovered oil as base oil, which not only enables cost to be saved but also allows environmental pollution to be reduced; the chlorine-containing extreme pressure agent chlorinated paraffin S52 and the sulfur-containing extreme pressure agent RC4801 are used as extreme pressure agents for the metalworking liquid, so the extreme-pressure metalworking liquid is suitable for machining with a great processing temperature range; benzisothiazolone and 3-iodine-2-propenyl-butylcarbamate are used as antiseptics, which enables the service life of a product to be prolonged. The metal processing liquid provided by the invention is suitable for a wide variety of machining, such as complex processing technologies like cutting, turning, drilling, grinding, boring and milling.
