棕榈油合成的烷醇酰胺作为水基切削液添加剂的性能

摘要

通过棕榈油与有机醇胺的二步法反应，制备出6502型烷醇酰胺。将质量分数13％的6502型烷醇酰胺作为添加剂加入全合成水基金属切削液中，对其性能进行研究。结果表明，该切削液具有良好的极压抗磨性和耐腐蚀性，其摩擦因数可低至0.062，最大无卡咬负荷（pB值）达到367 N；对一级灰口铸铁的耐腐蚀性能达到A级（24 h）；各种性能均达到GB／T 6144-2010标准。%6502 type alkanolamide was synthetized by two-step reaction of palm oil and organic alcohol amine. The cut-ting fluid was prepared by adding 13%(weight)of the 6502 type alkanolamide,and its performance was evaluated. The results show that the prepared cutting fluid has excellent extreme pressure,anti-wear and anti-corrosion properties,its fric-tion coefficient is as low as 0.062,and the maximum non-seizure load reaches 367 N. The anti-corrosion of the diluent of cutting fluid for iron reaches A level for 24 h. The comprehensive performance of the cutting fluid with 13%(weight)of the 6502 type alkanolamide can reach the national standard of GB/T 6144-2010 .
