Embodiment 1

[0041] Synthesis of extreme pressure antiwear agent 1-methyl-3-dodecylimidazolium borate-modified lanthanum carbonate complex: a. Dissolve 60g of lanthanum chloride in distilled water and stir until clear liquid; b. Add dropwise an ethanol solution containing 30g of 1-propyl-3-dodecylimidazolium tetrafluorophosphoric acid and 31.8g of sodium carbonate under stirring, the solution immediately becomes white and turbid, and reacts at constant temperature for 2 hours, and the reaction is complete; c. Chemical, filtered, and precipitated with distilled water for several times, and then washed several times with absolute ethanol; d. Finally, washed several times with potassium tetrafluoroborate aqueous solution for particle exchange, dried to obtain samples, and finely ground for later use. The structural formula of the synthetic polar antiwear agent is:

[0042]

[0043] , due to the influence of the reaction process, n in the synthetic product is 10~40.

[0044] Add the polar ...

Embodiment 2

[0055] Synthesize the lanthanum carbonate complex modified by the extreme pressure antiwear agent 1-methyl-3-dodecylimidazolium borate, the method is the same as that of Example 1,

[0056] To prepare a water-based metalworking fluid added with the above-mentioned extreme pressure antiwear agent, the raw materials are weighed according to the following components by weight:

[0057] Base liquid: 90 parts,

[0058] Oily agent: 19 parts,

[0059] Extreme pressure antiwear agent: 12 parts,

[0060] Anti-rust anti-rust agent: 3 parts,

[0061] Fungicide: 2 parts.

[0062] The base fluid is water: ethylene glycol = 10:1 water-ethanol mixture; the oily agent is water-soluble polyether; the antirust agent is benzotriazole. A water-based metalworking fluid is prepared by a conventional method in the art. The water-based metalworking fluid prepared in Comparative Example 2 does not add the extreme pressure antiwear agent prepared above, and the types and parts of other components ar...

Embodiment 3

[0068] Synthesis of extreme pressure antiwear agent 1-methyl-3-dodecylimidazolium borate-modified lanthanum carbonate complex: a. Dissolve 60g of lanthanum bromide in distilled water and stir until clear liquid; b. Add drop by drop an ethanol solution containing 60g of 1-propyl-3-dodecylimidazolium tetrafluorophosphoric acid and 31.8g of sodium carbonate under stirring, the solution immediately becomes white and turbid, reacts at constant temperature for 2 hours, and the reaction is complete; c. Chemical, filtered, and precipitated with distilled water for several times, and then washed several times with absolute ethanol; d. Finally, washed several times with potassium tetrafluoroborate aqueous solution for particle exchange, dried to obtain samples, and finely ground for later use. The structural formula of the synthetic polar antiwear agent is:

[0069]

[0070] Due to the influence of the reaction process, the mixture in which n is 10~40 in the synthesized product.

Abstract

The invention discloses an extreme-pressure anti-wear agent, a preparation method of the extreme-pressure anti-wear agent and application of the extreme-pressure anti-wear agent to a water-based metal working fluid and belongs to the field of metal working. The extreme-pressure anti-wear agent is a 1-methyl-3-dodecylimidazole borate modified lanthanum carbonate compound. The water-based metal working fluid comprises the following components in parts by weight: 70-90 parts of a basic fluid, 10-19 parts of an oiliness agent and 2.3-12 parts of the extreme-pressure anti-wear agent. The invention further discloses a preparation method of the extreme-pressure anti-wear agent. The water-based metal working fluid with the extreme-pressure anti-wear agent has favorable wear resistance, rust resistance, corrosion resistance and other properties, is environment-friendly, has a huge application prospect, and can be used for promoting the metal working fluid industry to develop toward environmental compatibility, biological degradability and renewability.

Description

technical field [0001] The invention belongs to the field of metal processing, and more specifically relates to an extreme pressure antiwear agent, a preparation method thereof and an application in water-based metal processing fluid. Background technique [0002] Since the advent of water-based metalworking fluids in the 1940s, due to the incomparable cooling performance and low cost of oil-based fluids, it has attracted widespread attention in the market, resulting in the original oil-based metalworking fluids being gradually replaced by water-based metalworking fluids. (Especially the water-based metalworking fluid for full processing) instead. Water-based metalworking fluids have gone through the process of developing from emulsions to synthetic fluids and then to microemulsions in western developed countries, and microemulsions have been developed and applied unprecedentedly. In my country, metalworking fluids are still dominated by emulsions. In the 1980s, there w...
