[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 has solved the problems of large amount of lubricant used and serious pollution. However, there are still some limitations in the application of micro-quantity lubricant research. Problems, mainly lubrication and cooling problems can not be solved well

Embodiment 1
[0029] Weigh 116.07g (1mol) of glucose, 232.14g (2mol) of maleic acid, and 600g (3mol) of PEG200 into the reaction kettle, stir and heat to 190°C, fully react for 12 hours, depressurize and drain the water, which is a kind of lubrication agent composition.
[0030] Weigh 400g of the above lubricant composition, 300g of di-isooctyl adipate, 100g of tetrapolyricinoleic acid ester, 200g of sodium oleyl amidoate, mix and stir at 60°C until it becomes transparent, then it becomes a kind of micro-cutting fluid.
[0031] The above micro-cutting fluid was subjected to four-ball extreme pressure test with GB / T12583 experimental method, and the test result: P D >620(kgf).
Embodiment 2
[0033] Weigh 116.07g (1mol) of glucose, 354.27g (1mol) of succinic acid, 600g (2mol) of PEG300, and 20g of phosphoric acid (50%) into the reaction kettle, stir and heat to 260°C, fully react for 6 hours, and drain the water under reduced pressure , which is a lubricant composition.
[0034] Weigh 300g of the above lubricant composition, 400g of diisooctyl adipate, 200g of hexapolyricinoleic acid ester, and 100g of sodium oleyl amidoate, mix and stir at 40°C until it becomes transparent, then it becomes a kind of micro-cutting fluid.
Embodiment 3
[0036] Weigh 116.07g (1mol) of glucose, 365.35g (2.5mol) of adipic acid, and 480g (1.2mol) of PEG400 into the reaction kettle, stir and heat to 240°C, fully react for 8 hours, and drain the water under reduced pressure, which is a A lubricant composition.
[0037] Weigh 350g of the above-mentioned lubricant composition, 350g of di-isooctyl adipate, 150g of polyricinoleic acid ester, and 150g of sodium oleyl amidoate, and mix and stir at about 50°C until it becomes transparent.

Abstract
The invention provides a lubricant composition which is characterized by comprising the following components or being prepared from the following raw materials: glucose, dicarboxylic acid and polyethylene glycol in a molar ratio of 1: (2-3): (1-3). By adopting the lubricant composition prepared by the preparation method, as the synthesized polyester compound has excellent lubricity, good extreme pressure antiwear property and excellent in water solubility, is an excellent surfactant too, and can replace a conventional chlorine, sulfur and phosphorus-containing extreme pressure antiwear agent fully or partially to be used in a microcutting fluid to meet the demands of lubricating and cooling, extreme pressure wear resistance and rust prevention in metalmachining. Matched with a micro lubricating device in use, the use level of the cutting fluid can be saved by over 90%, energy is saved and emission is reduced, and the environmental protection effect is obvious.
Description
technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a lubricant composition, a preparation method thereof and a micro cutting fluid prepared by the composition. Background technique [0002] The traditional metalcutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of showerlubrication. 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 has solved the above problems such as large amount of lubricant used and serious pollution, but the research on micro-quantity lubricant still has certain limitations in application. The problem is that the lubrication a...
