| 目的 研究原位制备胆碱氨基酸离子液体水润滑添加剂的摩擦学性能、物理化学性能及其毒性。方法 以氨基酸和胆碱为原料，在去离子水中原位制备7种氨基酸离子液体水润滑添加剂（[Ch][AA] ILs）。以去离子水为对照样，对其摩擦学性能、物理化学性质进行系统研究。以传统离子液体1-丁基-3-甲基咪唑四氟硼酸盐（L-B104）为对照样，绿藻和海虾作为实验对象，对其水生生物毒性进行评价。结果 添加不同种胆碱氨基酸离子液体添加剂后，水溶液的运动黏度明显增加，并且呈现出递增的趋势。浸泡在含400 mmol/L胆碱氨基酸离子液体的水基润滑剂中时，铸铁棒条的腐蚀极为轻微。作为润滑剂使用时，测试原位制备的胆碱氨基酸离子液体水基润滑剂的浓度为400 mmol/L时的减摩抗磨性能，其摩擦系数都比水小。毒性试验显示，[Ch][AA] ILs的半抑制浓度（EC50）和半致死浓度（LC50）值远远大于L-B104。结论 与去离子水相比，以胆碱氨基酸离子液作为水润滑添加剂，在钢/钢摩擦副上表现出优异的润滑性能。其中，含有芳杂环的[Ch][Trp]具有最优异的减摩抗磨性能，其摩擦学系数和磨损体积最小。这可能归因于芳杂环的引入使得含有该离子液体添加剂的水溶液黏度显著增大，在摩擦过程中能够形成更牢固的润滑保护膜，从而使该氨基酸胆碱离子液体具备优越的减摩抗磨性能。在毒性试验中发现，氨基酸胆碱离子液体水润滑剂的毒性远小于传统离子液体（L-B104），对试验生物体基本无毒害作用。 |

| The work aims to study the tribological properties, physicochemical properties and toxicity of in situ preparation of choline amino acid ionic liquid water lubricated additives. Seven kinds of amino acid ionic liquid lubricating additives ([Ch][AA] ILs) were prepared in situ from amino acid and choline in deionized water. Firstly, its tribological properties and physicochemical properties were systematically studied with deionized water as a reference sample. Then, the traditional ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate (L-B104) was used as control sample, and green algae and sea shrimp were used as experimental objects to evaluate the aquatic toxicity of the additives. The kinematic viscosity of aqueous solution increased significantly and showed an increasing trend after adding different kinds of choline amino acid ionic liquid additives. The corrosion of iron bars immersed in aqueous solution containing 400 mmol/L amino acid choline ionic liquid was very slight. When used as lubricant, water-based lubricants with ionic liquid concentration of 400 mmol/L were selected to test the antifriction and antiwear properties of amino acid ionic liquids prepared in situ, and their friction coefficients were smaller than those of water. Toxicity tests showed that the values of EC50 and LC50 of [Ch][AA] ILs were much higher than those of L-B104. Compared with deionized water, choline amino acid ionic liquid as water lubricating additive exhibits excellent lubrication performance on steel/steel friction pairs. Among them, [Ch][Trp] containing aromatic heterocycles has the best antifriction and antiwear properties, and its tribological coefficient and wear volume are the smallest. This may be attributed to the significant increase in the viscosity of aqueous solution containing the ionic liquid additive due to the introduction of aromatic heterocycles. A strong physical adsorption protective film is formed during the friction process, which makes the amino acid choline ionic liquid possess superior wear resistance. In the toxicity test, the toxicity of amino acid choline ionic liquid lubricant is much less than that of traditional ionic liquid (L-B104). It has no toxic effect on the experimental organisms. |
