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。

Abstract: | Twelve acid diethanolamide boric acid ester was prepared by using twelve acid and diethanolamine and boric acid as raw materials,and its structure was analyzed by using Fourier Transform Infrared Spectrometer.A semi synthetic cutting fluid was prepared by adding a certain amount of 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 synthetic 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. |
