Embodiment 1

[0023] The borate of the monoethanolamine salt of ethyl phosphorothioate, its synthetic steps are:

[0024] a. Put 0.2mol boric acid, 0.64mol monoethanolamine and a small amount of toluene into a three-necked flask equipped with a stirrer, a thermometer and a water separator as water-carrying agents, stir and react at 100-120°C for 4-8 hours, and wait for the water separator After the water in the solution no longer increases, the reaction ends, and after the remaining toluene, a small amount of water and excess monoethanolamine are removed by distillation under reduced pressure, a light yellow viscous liquid is obtained, which is monoethanolamine borate;

[0025] b. Add 1.3mol ethanol to the three-necked flask, and connect the gas absorption device (aqueous solution of NaOH), use n-heptane as solvent, add 0.4mol P in batches under vigorous stirring 2 S 5 , continue to stir at room temperature for 0.5 ~ 1h, the reaction proceeds violently, exothermic and accompanied by a larg...

Embodiment 2

[0028] The borate of the monoethanolamine salt of polyethylene glycol thiophosphate, its synthetic steps are:

[0029] a. Put 0.2mol boric acid, 0.8mol monoethanolamine and a small amount of toluene into a three-necked flask equipped with a stirrer, a thermometer and a water separator as a water-carrying agent, stir and react at 100-120°C for 4-8 hours, and put it in the water separator After the water no longer increases, the reaction ends, and after the remaining toluene, a small amount of water and excess monoethanolamine are removed by distillation under reduced pressure, a light yellow viscous liquid is obtained, which is monoethanolamine borate;

[0030] b. Add 1.2 mol polyethylene glycol (PEG 200) into a three-necked flask, connect it to a gas absorption device (aqueous solution of NaOH), use n-heptane as a solvent, and add 0.3 mol P in batches under vigorous stirring. 2 S 5 , continue to stir at room temperature for 0.5 ~ 1h, the reaction proceeds violently, exothermi...

Abstract

The invention discloses a water-based additive having antirust extreme-pressure capability, a structural formula is shown in specification, wherein R1 is alcohol with carbon atom being less than 4. According to the invention, sulfur and phosphor elements with strong extreme-pressure antiwear capability are introduced in monoethanolamine borate molecules with good anlirust property through a molecule design viewpoint, and the water-based additive with low cost possessing antirust property and extreme-pressure capability can be synthesized. The synthesized water-based additive possessing antirust property and extreme-pressure capability can be directly dissolved in water, and can be the additive of the water-based lubricant for widely being used in metal processing field.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil additive organic compounds, and in particular relates to a water-based additive with anti-rust extreme pressure capability, a preparation method of the water-based additive, and an application of the water-based additive as a lubricating oil additive. Background technique [0002] As countries all over the world pay great attention to energy and environmental protection issues, oil depletion, energy crisis and environmental pollution have become major worldwide problems. From the perspective of sustainable development, in order to reduce the long-term dependence on petroleum in metal processing and lubrication, the development of green and environmentally friendly water-based lubricants with excellent performance has great social significance and market prospects. Due to the advantages of water-based lubricating materials from a wide range of sources, convenient storage and transportation,...
