摘　　要：采用十二酸、二乙醇胺和硼酸为原料制备十二酸二乙醇酰胺硼酸酯,采用傅里叶变换红外光谱仪分析其结构。将一定量的该硼酸酯加入基础油中制备一种半合成切削液,分析其腐蚀性能和防锈性能,并通过四球摩擦试验机测试其极压抗磨性能。结果表明;制备的硼酸酯在半合成切削液中具有良好的极压抗磨性能,当硼酸酯的质量分数为11.3%时,5%切削液稀释液的摩擦因数达到0.056,最大无卡咬负荷达到392 N。采用该硼酸酯制备的半合成切削液的各性能指标达到GB/T 6144-2010标准。Twelve acid diethanolamide boric acid ester acid as raw materials, and its structure was analyzed by cutting fluid was prepared by adding a certain amount of was prepared by using twelve acid and diethanolamine and boric using Fourier Transform Infrared Spectrometer. A semi-synthetic boric acid ester into the base oil, the corrosion performance and anti-rust property were analyzed, and the extreme pressure and anti-wear properties were tested by four ball friction testing machine.The results show that the prepared borate ester has good extreme pressure and anti-wear properties in semi-syn- thetic cutting fluid ,when the mass fraction of boric acid ester is 11.3% ,the friction coefficient of 5% diluent of the cutting fluid reaches 0. 056 and maximum non-seizure load reaches 392 N.The performance indicators of the semi synthetic cutting fluid with the borate ester as additive meet the national standard of GB/T 6144-2010.
