Novel cryogenic cutting fluid

Abstract

The invention discloses a novel cryogenic cutting fluid, which is prepared from the following raw materials by weight: 3.5-8.5 parts of borax, 3.5-9 parts of pentaerythritol fatty acid synthetic grease, 1.5-4.5 parts of barium acrylate, oil amide 3.5-7.5 parts of Tallol oleamide and 1.5-3.5 parts of caproyl triazole. Compared with the existing cutting fluid, the cutting fluid provided by the invention has excellent lubricating extreme pressure properties, and a 10% water solution extreme pressure test shows that the PB value can reach 70 kgf, which fully meets the lubrication requirements for synthesizing cutting fluid. The cutting fluid has excellent corrosion and rust-resisting properties, is applicable to processing of a plurality of materials such as cast iron, alloy steel, stainless steel and aluminum alloy, and can reach rust prevention during manufacture on black metal for 7-15 days. In addition, the cutting fluid has the advantages of good biological stability, long service life, no stinking, good cooling and good cleaning performance, cleaning workpiece after machining, no carcinogenic sodium nitrite, good environment-friendliness and safety for usage.

Description

technical field [0001] The invention relates to a novel low-temperature 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...
