Environment-friendly extreme-pressure cutting fluid

Abstract

The invention discloses an environment-friendly extreme-pressure cutting fluid which is prepared from the following raw materials in parts by weight: 3.5-8.5 parts of polyethyleneglycol monostearate, 3.5-9 parts of butyloctanol sulfate zinc, 1.5-4.5 parts of barium acrylate, 3.5-7.5 parts of tall oil amide and 1.5-3.5 parts of molybdenum disulfide. Compared with the existing cutting fluid, the cutting fluid disclosed by the invention has excellent extreme-pressure lubricating property, and the 10% water solution extreme-pressure property detection indicates that the PB value can reach 70 kgf and completely satisfy the requirement of the synthetic cutting fluid for lubricating property; the cutting fluid has excellent corrosion resistance and antirust property, is suitable for processing cast iron, alloy steel, stainless steel, aluminum alloy and many other materials, and can resist rust for 7-15 days in a ferrous metal process; the cutting fluid has the advantages of high biological stability, long service period and low stinking tendency; the cutting fluid has favorable cooling property and cleaning property, and the processed workpiece is very clean; and the cutting fluid is free of cancerigenic sodium nitrate, environment-friendly, and safe to use.

Description

technical field [0001] The invention relates to an environment-friendly extreme pressure 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 perfor...

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.
