Description
Technical Field
The invention belongs to the technical field of lubricants, and particularly relates to an ionic liquid lubricant, in particular to a halogen-free heterocyclic sulfonic acid ionic liquid lubricant with excellent tribological performance on titanium alloy, and a preparation method and application thereof.
Background
It is known that the titanium element is widely distributed in the earth crust, and is located in the tenth place of the metal element. Despite such abundance of titanium element, titanium alloy for industrial use was not developed for the first time until 1954. Therefore, the titanium alloy is widely applied to various industries such as aerospace, chemical engineering, sports and the like. The titanium alloy can be developed widely and rapidly, and is mainly due to the advantages of the titanium alloy material, such as: has the highest specific strength in metal materials, and has excellent performances of heat resistance, toughness, corrosion resistance, fatigue resistance and the like. However, as titanium alloys are used more and more widely, their drawbacks become increasingly revealed, such as: the hardness is low, and the adhesive wear is easy to cause; poor heat conductivity, easy occurrence of knife sticking phenomenon and the like. These inherent drawbacks have greatly limited the development and application of titanium alloys. Therefore, it becomes necessary to research and develop a lubricant for improving the tribological properties of titanium alloys.
Research shows that because titanium is active in nature, a dense oxide film is easily formed on the surface of a titanium alloy material in the air, so that a stable lubricating film is hardly formed on the surface of the titanium alloy by a plurality of liquid lubricants, particularly the untreated alloy surface. For example, mineral oil, polyalphaolefin and the like, which are traditional lubricants, have difficulty in achieving a good lubricating effect on titanium alloys. Therefore, attempts have been made to apply ionic liquids to titaniumIn alloys, it is desirable to improve the poor tribological properties of titanium alloys. Jimenez et al reported the use of imidazole-based ionic liquids as lubricants for steel/titanium friction pairs and showed that: compared with traditional mineral oil, with Cl - 、BF 4 - Or PF 6 - 、TFSI - Imidazole-based ionic liquids, which are anions, are effective in reducing the frictional wear of titanium alloys (TribolLett,2009,33(2): 111-. Li et al reported the effect of different fluorine-containing ionic liquid lubricants such as tetrafluoroborate and perfluorosulfonate on the tribological properties of TC21 titanium alloys, and the results showed that: the perfluorosulfonate ionic liquid is an excellent lubricant of TC21 titanium/Si 3N4 friction pair (J.alloys Compd.2018,743: 576-585).
However, the above ionic liquid lubricants are all halogen-containing compounds, and their use is difficult to meet the current environmental requirements. With the increasing awareness of environmental protection, the development of halogen-free environmentally friendly ionic liquid lubricants for improving the tribological properties of titanium alloys has become one of the important contents of current research in the lubrication field.
Disclosure of Invention
In view of the defects of the prior art, the first object of the present invention is to provide a halogen-free heterocyclic sulfonic acid ionic liquid, which has excellent friction reducing and wear resisting properties as a lubricant of a titanium alloy friction pair, and can significantly reduce the friction coefficient of a titanium alloy friction member and reduce the wear volume of the titanium alloy friction member in the friction process.
In order to achieve the above technical objects, the present inventors have conducted extensive experimental studies and diligent research, and finally obtained the following technical solutions: a halogen-free heterocyclic sulfonic acid ionic liquid has a structure shown in the following general formula (I):
wherein X is P element or N element, R 1 、R 2 、R 3 And R 4 Each independently selected from alkyl groups having 1 to 16 carbon atoms.
Further excellenceOptionally, the halogen-free heterocyclic sulfonic acid ionic liquid is as described above, wherein X is P element or N element, R 1 、R 2 、R 3 And R 4 The alkyl groups have the same structure and are all selected from alkyl groups with 4-8 carbon atoms.
Still further preferably, the halogen-free heterocyclic sulfonic acid ionic liquid as described above, wherein X is P element or N element, R is 1 、R 2 、R 3 And R 4 The alkyl groups have the same structure and are all selected from alkyl groups with 4 or 8 carbon atoms.

In addition, a second object of the present invention is to provide a method for preparing the halogen-free heterocyclic sulfonic acid ionic liquid, which comprises the following steps: mixing tetraalkyl phosphonium bromide or tetraalkyl amine bromide and 3- (benzothiazole-2-mercapto) propane sodium sulfonate in a reaction solvent, stirring and reacting for 24-48 hours at 58-62 ℃, extracting reaction liquid by using dichloromethane after the reaction is finished, washing an extraction layer for 1-5 times by using deionized water, dissolving and filtering by using acetonitrile after evaporating the solvent under reduced pressure, evaporating the solvent under reduced pressure again, and drying to obtain a target product.
Further preferably, the halogen-free heterocyclic sulfonic acid ionic liquid is prepared by the method, wherein the molar ratio of the tetraalkyl phosphonium bromide or the tetraalkyl amine bromide to the sodium 3- (benzothiazole-2-mercapto) propane sulfonate is 1: 2-1: 3.
Further preferably, the halogen-free heterocyclic sulfonic acid ionic liquid is prepared by a method as described above, wherein the reaction solvent is one or more selected from the following: methanol, water and acetone.

Therefore, the third purpose of the invention is to provide a new application of the halogen-free heterocyclic sulfonic acid ionic liquid as a lubricant for titanium alloy.
