[0010] The present invention is a new type of environmentally friendly lubricating cutting fluid, which is made of the following raw materials in parts by weight:

[0011] 4.5 parts of primary and secondary alkyl zinc salt of sulfur phosphorus, 6.5 parts of phenylalanine, 35 parts of kerosene, 12 parts of deionized water, 8 parts of glycerin, 1.8 parts of benzisothiazolinone and 2.2 parts of styrene maleic anhydride.

Embodiment 2

[0013] The present invention is a new type of environmentally friendly lubricating cutting fluid, which is made of the following raw materials in parts by weight:

[0014] 2.5 parts of primary and secondary alkyl zinc salt of sulfur phosphorus, 3.5 parts of phenylalanine, 25 parts of kerosene, 10 parts of deionized water, 5 parts of glycerin, 1.5 parts of benzisothiazolinone and 0.8 parts of styrene maleic anhydride.

Embodiment 3

[0016] The present invention is a new type of environmentally friendly lubricating cutting fluid, which is made of the following raw materials in parts by weight:

[0017] 6.5 parts of primary and secondary alkyl zinc salt of sulfur phosphorus, 8.5 parts of phenylalanine, 55 parts of kerosene, 15 parts of deionized water, 10 parts of glycerin, 2.2 parts of benzisothiazolinone and 2.5 parts of styrene maleic anhydride.

[0018] 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, which fully meets the lubricity requirements of synthetic cutting fluid; it has excellent corrosion inhibition and anti-rust performance, suitable for the processing of various materials such as cast iron, alloy steel, stainless steel, aluminum alloy, etc., and can prevent rust between ferrous metals for 7-15 days; the invention has good biolog...

Abstract

A disclosed novel environment-friendly lubrication cutting fluid is prepared from the following raw materials in parts by weight: 2.5-6.5 parts of primary / secondary alkyl zinc dialkyldithiophosphate, 3.5-8.5 parts of phenylalanine, 25-55 parts of kerosene, 10-15 parts of deionized water, 5-10 parts of glycerin, 1.5-2.2 parts of 1,2-benzisothiazolin-3-one and 0.8-2.5 parts of styrene-maleic anhydride copolymer. Compared with conventional cutting fluids, the novel environment-friendly lubrication cutting fluid has excellent lubrication extreme pressure property; the extreme pressure property determination on a cutting-fluid water solution with a concentration of 10% shows that the PB value is up to 70 kgf, and the extreme pressure property totally satisfies the lubrication requirements of synthetic cutting fluids; the novel antirust cutting fluid has excellent corrosion mitigation and antirust performances, and is applicable to processing on multiple materials such as cast iron, alloy steel, stainless steel, aluminium alloy and the like; the novel antirust cutting fluid is good in biological stability, long in service life and not easy to stink; the novel antirust cutting fluid has good cooling property and cleaning property, and processes workpieces are clean; and the novel antirust cutting fluid has good environment protection property and safe usage.

Description

technical field [0001] The invention relates to a novel environment-friendly 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 perfor...
