Problems solved by technology

[0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators.
[0003] In order to solve these problems, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology solves the above problems such as large amount of lubricant used and serious pollution. At the same time, in order to make the micro-quantity lubricant used have relatively strong extreme pressure and anti-wear Sex and lubricity, excessive use of sulfur- and chlorine-containing additives that are not friendly to the environment, the use of minimal lubrication technology can solve the problem of large-scale use of cutting fluid and environmental pollution, but it is applied to difficult-to-machine metals such as titanium alloys, When processing tungsten steel alloy, stainless steel, etc., it is often difficult to achieve the required lubrication effect with the existing minimal quantity lubrication technology

Embodiment 1

[0029] Weigh 191.14g (1mol) of aminotriacetic acid, 390.69g (3mol) of isooctyl alcohol, and 11g of phosphotungstic acid, place them in a reaction kettle, stir and heat to 180°C, and fully react for 6 hours. During the reaction process, drain water under reduced pressure every 2 hours 1 time, after the reaction is completed, the water is decompressed and removed; it is an anti-wear lubricating oil composition.

[0030] Weigh 500 g of the anti-wear lubricating oil composition and 500 g of diisoeicosyl 2,5-furandicarboxylate, mix and stir at room temperature until it is completely transparent, then it becomes an anti-wear micro-lubricant oil.

[0031] The preparation method of the above-mentioned 2,5-furandicarboxylic acid diisoeicosyl ester: 2,5-furandicarboxylic acid 156.09g (1mol) and isoeicosanol 656.81g (2.2mol), 10g dilute sulfuric acid (10%) Put it into the reaction kettle and react at the reaction temperature of 200°C for 5 hours; drain the water once under reduced pressu...

Embodiment 2

[0033] Weigh 191.14g (1mol) of aminotriacetic acid, 443.18g (2.8mol) of isodecyl alcohol, and 7g of phosphotungstic acid, place them in a reaction kettle, stir and heat to 200°C, and fully react for 5 hours. After the reaction is completed, water is removed under reduced pressure; that is, an anti-wear lubricating oil composition.

[0034] Weigh 600 g of the anti-wear lubricating oil composition and 400 g of di-isodecyl 2,5-furandicarboxylate, mix and stir at room temperature until it is completely transparent, then it becomes an anti-wear micro lubricating oil.

[0035] The preparation method of the above-mentioned diisodecyl 2,5-furandicarboxylate: add 156.09 g (1 mol) of 2,5-furandicarboxylic acid, 316.56 g (2 mol) of isodecyl alcohol, and 2 g of phosphotungstic acid into the reaction kettle, and React at a reaction temperature of 180°C for 6 hours; during the reaction process, drain water under reduced pressure once every 2 hours, and remove water under reduced pressure af...

Abstract

The invention provides an antiwear lubricating oil composition which is characterized by being prepared from nitrilotriacetic acid, fatty alcohol and phosphotungstic acid, and the molar ratio of nitrilotriacetic acid to fatty alcohol is 1: (2.5-3). The weight of the phosphotungstic acid is 1-2% of the total weight of the nitrilotriacetic acid and the fatty alcohol. The antiwear lubricating oil composition is a P-W-N-containing extreme-pressure antiwear additive, has excellent antifriction performance, and can completely or partially replace S and Cl extreme-pressure antiwear agents having adverse effects on the environment. The invention further provides antiwear trace lubricating oil containing the antiwear lubricating oil composition, and the antiwear trace lubricating oil is characterized by being prepared from the following components in percentage by weight: 50-60% of the antiwear lubricating oil composition; and 40 to 50% of 2, 5-furandicarboxylic acid dialiphatic alcohol ester.The antiwear trace lubricating oil prepared by the invention can meet the requirements of lubrication cooling, extreme pressure wear resistance and rust prevention in metal processing; and the use amount of a lubricant can be saved by more than 95% by matching with a minimal quantity lubricating device, and the effects of energy conservation, emission reduction and environmental protection are remarkable.
