A watersoluble antirust additive,dodecenylsuccinic acid diethanolamide (T746-X),was synthesized using a twostep method and with dodecenylsuccinic acid (T746),methanol,and diethanolamine as raw materials.The optimal reaction conditions were determined by using orthogonal experiments.The structure of the organic synthesis product was identified by Fourier transform infrared spectroscopy.The rustpreventing performance of the cutting fluid in waterbased cutting fluid was studied by the hygrothermal method,electrochemical polarization curve and electrochemical impedance spectroscopy (EIS).The performance of the cutting fluid was evaluated according to JB/T 7453-2013 semisynthetic cutting fluid industry standard.Infrared spectrum analysis shows that the synthesized product is an aliphatic alkyl alcohol amide compound.The analysis results by hygrothermal method and electrochemical method prove that the rust inhibitor T746-X can improve the antirust performance of the semisynthetic cutting fluid system.The semisynthetic cutting fluid with antirust agent T746-X concentration of 3.75 g/L has good antirust performance,and all the performances meet the technical requirements of JB/T 7453-2013.
