An Improved Lubricating Cutting Fluid

Abstract

The invention discloses an improved lubricating cutting fluid, which is prepared from the following raw materials in parts by weight: 2.5-6.5 parts of primary and secondary alkyl zinc salt of sulfur phosphorus, 3.5-8.5 parts of alkenyl dibutyric acid, 25-55 parts of kerosene, 10-15 parts of deionized water, 5-10 parts of glycerin, 1.5-2.2 parts of benzisothiazolinone and 0.8-2.5 parts of sodium dodecylbenzenesulfonate. Compared with the existing cutting fluid, the present invention has excellent lubricating extreme pressure performance, and the extreme pressure test of 10% aqueous solution shows that the PB value can reach 70kgf, fully meeting the lubricity requirements of synthetic cutting fluid; it has excellent corrosion inhibition and anti-rust performance, suitable for the processing of cast iron, alloy steel, stainless steel, aluminum alloy and other materials; the invention has good biological stability, long service life, and is not easy to stink; The workpiece is very clean; it is environmentally friendly 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.
