Embodiment 1

[0041] The embodiment of the present application provides a lubricant, and the specific preparation method includes:

[0042] (1) The isononanoic acid of 46% mass percentage is dropped in the reactor, is warming up to 90 ℃, for subsequent use;

[0043] (2) The alcohol amine mixture of 54% mass percent is slowly dropped into the reactor containing isononanoic acid, and the alcohol amine mixture includes diisopropanolamine and diethanolamine; the mass ratio of diisopropanolamine and diethanolamine is 4: 1;

[0044] (3) Put the catalyst 18-crown ether-6 of 0.15% by mass of the sum of the mass of isononanoic acid and alcohol amine mixture into the reactor, raise the temperature to 120°C, react at this temperature for about 4h, and turn on the vacuum pump at the same time To discharge the water generated by the reaction, stop heating when no more water is distilled out.

[0045] (4) naturally cool to room temperature, discharge, marked as embodiment 1.

[0046] Carry out infrare...

Embodiment 2

[0048] The embodiment of the present application provides the tapping test of Example 1 and Comparative Examples 1 to 3, and the specific steps include:

[0049] Use the simulation testing machine to directly conduct the tapping test on the metal material with the reserved hole, and use the average torque value to evaluate the lubricating performance of its processing. Theoretically, the lower the tapping torque value, the better the lubricity.

[0050] Respectively with embodiment 1, comparative example 1 (phosphoric acid ester), comparative example 2 (tall oleic acid diethanolamide) and comparative example 3 (triethanolamine oleic acid soap) as solute, tap water as solvent, preparation embodiment 1, pair 1% working solutions of Example 1 (phosphate ester), Comparative Example 2 (tall oleic acid diethanolamide) and Comparative Example 3 (triethanolamine oleic acid soap).

[0051] The 1% working solutions of Example 1, Comparative Example 1 (phosphate ester), Comparative Exam...

Embodiment 3

[0056] The embodiment of the present application provides the CSM reciprocating friction test of embodiment 1 and comparative examples 1 to 3, and the specific steps include:

[0057] Respectively with embodiment 1, comparative example 1 (phosphoric acid ester), comparative example 2 (tall oleic acid diethanolamide) and comparative example 3 (triethanolamine oleic acid soap) as solute, tap water as solvent, preparation embodiment 1, pair 1% working solutions of Example 1 (phosphate ester), Comparative Example 2 (tall oleic acid diethanolamide) and Comparative Example 3 (triethanolamine oleic acid soap).

[0058] Utilize CSM reciprocating friction testing machine, be 10N at load, be that test embodiment 1, comparative example 1 (phosphoric acid ester), comparative example 2 (tall oleic acid diethanolamide) and comparative example 3 ( triethanolamine oleic acid soap) to obtain the coefficient of friction. CSM reciprocating friction test, in theory, the lower the coefficient of ...

The present application also provides a preparation method of a lubricant, comprising the following steps: mixing and reacting isononanoic acid, an alcohol amine mixture and a catalyst to prepare the lubricant according to claim 1; wherein, the alcohol amine mixture comprises two Isopropanolamine and Diethanolamine. The present application provides a lubricant and its preparation method and application, which effectively solves the technical problem that existing water-based lubricants cannot have both low-foaming and super-lubricating properties.

Description

technical field [0001] The application belongs to the technical field of metal processing, and in particular relates to a lubricant and its preparation method and application. Background technique [0002] Metalworking fluids have been rapidly developed due to their excellent cooling, cleaning, rust resistance, economy and safety, and are widely used in cutting, grinding, rolling, stamping, drawing, tapping and other metal processing fluids. processing field. However, due to its little or no oil content, the lubricating fluid has poor oiliness and insufficient lubricating performance, which affects the processing effect and limits the application range of water-based metalworking fluids. In addition, if the lubricant foam is rich, there will be problems such as affecting the quality and precision of processing, making cooling and lubrication ineffective, resulting in waste of bath volume, and causing damage to processing machine tools, tools and workpieces. Therefore, choo...
