自乳化酯在全合成切削液中的性能研究

为探讨自乳化酯作为全合成切削液主润滑剂的可能性，以聚醚、四聚蓖麻油酸酯、自乳化酯为润滑剂调配了不同的合成切削液；采用四球抗磨试验机以及攻丝扭矩试验机、液体循环泡沫试验机，考察3种润滑剂在全合成切削液中的润滑性能、抗磨性能及抗泡性能。结果表明：自乳化酯能有效提高全合成切削液的润滑性能和抗磨性能，其润滑性能及抗磨性能与四聚蓖麻油酸酯相当；自乳化酯的抗泡性能显著优于四聚蓖麻油酸酯，与聚醚类润滑剂抗泡性能相当。自乳化酯具有良好的润滑及抗磨作用，且泡沫相对较低，可以与其他类型添加剂复配，用于全合成切削液中。

Study on the Properties of Self Emulsifying Ester in Synthetic Cutting Fluid

In order to explore the possibility of self emulsifying ester as the main lubricant of the synthetic cutting fluids,different synthetic cutting fluids were prepared with polyether,tetramer of castor oil and self emulsifying ester as lubricants.The lubrication,anti wear and anti foam performances of the 3 lubricants in the synthetic cutting fluids were investigated by using four ball testing machine,tapping torque tester and liquid circulating foam testing machine.The results show that the self emulsifying ester can effectively improve the lubrication and anti wear performances of the synthetic cutting fluids,and its lubrication and anti wear performances are similar to that of tetramer of castor oil.The anti foaming property of self emulsifying ester is better than that of tetramer of castor oil,and its anti foam performance is equivalent to that of polyether lubricant.
