Improved lubricating cutting fluid

Abstract

The invention discloses improved lubricating cutting fluid. The improved lubricating cutting fluid is prepared from the following raw materials in parts by weight: 2.5-6.5 parts of sulfur-phosphor primary-secondary alkyl zinc salt, 3.5-8.5 parts of alkenyl dibutyric acid, 25-55 parts of kerosene, 10-15 parts of deionized water, 5-10 parts of glycerol, 1.5-2.2 parts of benzisothiazolinone and 0.8-2.5 parts of sodium dodecyl benzene sulfonate. Compared with the existing cutting fluid, the improved lubricating cutting fluid disclosed by the invention has excellent lubricating extreme pressure performance, PB (Particle Beam) value shown by extreme pressure performance detection of 10% aqueous liquor can reach 70 kgf, so that lubricating requirements of synthesized cutting fluid can be completely satisfied; the improved lubricating cutting fluid has excellent corrosion inhibiting and anti-rusting performances, and is suitable for processing multiple materials such as cast iron, alloy steel, stainless steel and aluminum alloy. The improved lubricating cutting fluid disclosed by the invention is good in biological stability, long in service cycle and not easy to stink; cooling performance and cleaning performance are good, so that a processed workpiece is very clean; besides, the improved lubricating cutting fluid is good in environment-friendliness and safe to use.

Description

technical field [0001] The invention relates to an improved lubricating cutting fluid, which belongs to the field of industrial chemical industry. Background technique [0002] Since fully synthetic metalworking fluid does not contain mineral oil, polyether is usually used to increase the lubricating performance of the machining fluid. In view of its limited lubricating extreme pressure performance, fully synthetic cutting fluid is mainly used in grinding processing and some places that do not require extreme pressure lubrication. High material and workmanship. For harsh and difficult materials and processes (materials such as stainless steel, high-hard alloy steel, etc.; processes such as tapping, deep hole drilling, reaming, etc.), metalworking fluids with high lubricating and extreme pressure properties must be used, and sometimes even Use cutting oil for processing. However, the existing cutting fluids have poor corrosion inhibition and antirust performance, short serv...

AI Technical Summary

Problems solved by technology

However, the existing cutting fluids have poor corrosion inhibition and antirust performance, short service life, easy to stink, and the cleanliness of the workpiece after processing is very low.
