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, but also a certain anti-rust function to ensure that the processed workpieces will not rust when they enter the next process. Therefore, metalworking fluid manufacturers are producing cutting It is necessary to add a large amount of antirust agent and lubricant at the same time to meet the requirements of mechanical processing. How to reasonably compound various antirust agents, lubricants and other additives will determine the overall performance of the metalworking fluid.
[0004] Metalworking fluids include emulsions, microemulsion cutting fluids, and fully synthetic cutting fluids. At present, microemulsion cutting fluids are the most widely used in the market, but many products have many disadvantages such as poor lubricity, poor rust resistance, or short service life.

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.
