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 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

[0031] Weigh 182.17g (1mol) of sorbitol, 1129.84g (2mol) of dimer acid, and 600g (3mol) of PEG200 into the reaction kettle, stir and heat to 180°C, fully react for 12 hours, and drain the water under reduced pressure, which is a A lubricant composition.

[0032] Weigh 400g of the above-mentioned lubricant composition, 300g of diisodecyl adipate, 200g of sodium oleyl sulfate, 50g of tetrameric ricinoleic acid ester, and 50g of sodium oleyl amidoate, mix and stir at 60°C until it becomes transparent. It is an environmentally friendly micro-cutting fluid.

[0033] The above-mentioned environmentally friendly micro-cutting fluid was tested by the four-ball extreme pressure test method of GB / T12583, and the test result: P D >4903N.

Embodiment 2

[0035] Weigh 182.17g (1mol) of sorbitol, 1694.76g (3mol) of dimer acid, 600g (2mol) of PEG300, and 25g of phosphoric acid (effective component 50%) into the reaction kettle, stir and heat to 240°C, and fully react for 6 Hours, the water is decompressed and discharged, which is a lubricant composition.

[0036] Weigh 300g of the above-mentioned lubricant composition, 400g of diisodecyl adipate, 100g of sodium oleyl sulfate, 100g of hexameric ricinoleic acid ester, and 100g of sodium oleyl amidoate, mix and stir at 40°C until transparent. It is an environmentally friendly micro-cutting fluid.

Embodiment 3

[0038] Weigh 182.17g (1mol) of sorbitol, 1412.3g (2.5mol) of dimer acid, and 480g (1.2mol) of PEG400 into the reaction kettle, stir and heat to 230°C, fully react for 8 hours, and drain the water under reduced pressure, that is as a lubricant composition.

[0039] Weigh 350g of the above lubricant composition, 350g of diisodecyl adipate, 150g of sodium oleyl sulfate, 80g of polyricinoleic acid ester, and 70g of sodium oleyl amidoate, mix and stir at a temperature of about 50°C until it becomes transparent. It is an environmentally friendly micro-cutting fluid.

Abstract

The invention provides a lubricant composition. The lubricant composition is prepared from the following raw materials: sorbitol, dimer acid and polyethylene glycol, wherein the molar ratio of the above-mentioned sorbitol to the dimer acid to the polyethylene glycol is 1: (2-3): (1-3). By adoption of the lubricant composition prepared by using the method provided by the invention, a synthetic polyester compound has excellent lubricity, good extreme pressure anti-wear properties and excellent water solubility, is also an excellent surfactant, and can completely or partially replace a traditional extreme pressure anti-wear agent containing chlorine, sulfur and phosphorus to be used in an environmentally-friendly micro cutting fluid, so a small amount of the environmentally-friendly micro cutting fluid can meet the requirements of lubrication cooling, extreme pressure wear resistance and rust prevention in metal processing; and by combination of the environmentally-friendly micro cuttingfluid with a micro lubrication device for application, the usage amount of the cutting fluid can be saved by 90% or above, and the effects of energy conservation, emission reduction and environmentalprotection are significant.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to an environmentally friendly micro cutting fluid and a preparation method thereof. Background technique [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 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 and cooling problems cannot ...
