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, the research on micro-quantity lubrication technology has made some progress recently. The micro-quantity lubrication technology has solved the problems of large amount of lubricant used and serious pollution. Excessive use of sulfur- and chlorine-containing additives that are not friendly to the environment, Developing a sulfur-free, chlorine-free microlubricant additive with excellent extreme pressure and antiwear properties is a challenge

Embodiment 1

[0030] Weigh 298.55g (1mol) of isoeicosanol and 192.14g (1mol) of citric acid into the reaction kettle together, stir and heat to 220°C, and after fully reacting for 3 hours, add polyethylene glycol (PEG1000 ) 140g, keeping the reaction temperature at 220°C, reacting for 2 hours, decompressing and discharging water after the reaction, which is a lubricant composition.

[0031] The lubricant composition prepared in Example 1 can be directly used as a micro-quantity lubricant, and it can be directly used in a micro-quantity lubrication device after adding 3 times of water and stirring until it becomes transparent.

Embodiment 2

[0033] Weigh 372.76g (2mol) of lauryl alcohol, 192.14g (1mol) of citric acid, and 2.8g of germanium dioxide and add them to the reaction kettle together, stir and heat to 200°C, and fully react for 5 hours. 120g of alcohol (PEG800) was kept at a reaction temperature of 200°C for 3 hours, and after the reaction, the water was depressurized and discharged to form a lubricant composition.

[0034] Weigh 100g of urea and dissolve it in 150g of water, add 400g of the above lubricant composition, 200g of isooctyl palmitate, 100g of dodecyldimethyl betaine, and 50g of organoboron compound, mix and stir at 60°C until transparent. A micro lubricant.

[0035] The preparation method of the above organoboron compound: weigh 100g of oleamide, 30g of boric acid, and 20g of hydroxyethylethanolamine, mix them at 100°C and stir for 1 hour, then vacuumize and decompress and heat up to 120°C (keep the pressure in the container not greater than 100mmHg), Stir for 2 hours, and filter the precipit...

Embodiment 3

[0038] Weigh 321.59g (1.5mol) of myristyl alcohol, 192.14g (1mol) of citric acid, and 0.6g of germanium dioxide into the reaction kettle, stir and heat to 208°C, and fully react for 4 hours. 130 g of polyethylene glycol (PEG600) is kept at a reaction temperature of 208° C., reacted for 2.5 hours, and after the reaction is decompressed to discharge water, which is a lubricant composition.

[0039] Weigh 50g of urea and dissolve it in 200g of water, add 300g of the above lubricant composition, 300g of isooctyl palmitate, 50g of dodecyldimethyl betaine, and 100g of organoboron compound, mix and stir at 50°C until transparent. A micro lubricant.

[0040] The preparation method of the above organoboron compound: weigh 100g of oleamide, 28g of boric acid, and 18g of hydroxyethylethanolamine, mix them at 99°C and stir for 1 hour, then vacuumize and decompress and heat up to 115°C (keep the pressure in the container not greater than 100mmHg), Stir for 2.5 hours, and filter the precip...

Abstract

The invention provides a lubricant composition which is characterized by being prepared from fatty alcohol, citric acid and polyethylene glycol, wherein the mole ratio of the fatty alcohol to the citric acid is (1-2):1; the weight ratio of the fatty alcohol to the polyethylene glycol is 100:(30-50). The lubrication composition provided by the invention is good in lubricating property and water solubility. The invention further provides a trace lubricant prepared from the lubricant composition. The trace lubricant is characterized by comprising components such as iso-octyl palmitate, dodecyl dimethyl betaine, an organoboron compound, urea and water. The trace lubricant provided by the invention is capable of meeting requirements of metallic processing on lubrication cooling, extreme pressure wearing resistance and rust prevention, and cooperating with a trace lubrication device, the consumption amount of the lubricant can be reduced by 90% or greater, and very remarkable effects of energy conservation, emission reduction and environment protection can be achieved.
