本发明配方的初始性能测试结果与市场中常见的航空航天铝合金切削液相近，但通过在客户现场半年时间的测试发现，该配方可以抑制工作液的变黑现象（如图1~2所示）。在本发明配方中，主要通过添加磷酸酯缓蚀剂RHODAFAC AS 010以保证在长期加工过程中铝件表面不变色，添加具有极压润滑及缓蚀性能的CPNF-3或MDIT及高缓蚀效率的硅类铝缓蚀剂Horlt C101，结合油性润滑剂季戊四醇四油酸酯或三羟甲基丙烷油酸酯，在加强切削液对加工工件保护作用的同时，还能对机床内部累积的铝屑进行保护，从而使铝屑在循环过程中不变色、不产生黑色悬浮物，进而实现保持切削液的清净性。The initial performance test result of the formula of the present invention is close to that of the common aerospace aluminum alloy cutting liquid in the market, but it is found through the test on the customer site for half a year that the formula can inhibit the blackening of the working fluid (as shown in Figures 1~2). Show). In the formula of the present invention, phosphate ester corrosion inhibitor RHODAFAC AS 010 is mainly added to ensure that the surface of aluminum parts does not change color during long-term processing, and CPNF-3 or MDIT with extreme pressure lubrication and corrosion inhibition performance is added and high corrosion inhibition efficiency The silicon-based aluminum corrosion inhibitor Horlt C101, combined with the oily lubricants pentaerythritol tetraoleate or trimethylolpropane oleate, can enhance the protection of the cutting fluid on the workpiece, and at the same time, it can also protect the aluminum chips accumulated inside the machine tool. Protect it so that the aluminum shavings will not change color during the cycle, and no black suspended matter will be produced, thereby maintaining the cleanness of the cutting fluid.
