    摘要:

    以亚磷酸二正丁酯和十二醇为原料,通过酯交换法合成亚磷酸双十二烷基酯。采用FTIR对其结构进行表征;以亚磷酸双十二烷基酯为极压抗磨剂,制备一种以多元醇酯为主油性剂的水基钢丝拉拔润滑剂,采用四球机和扫描电镜考察其摩擦性能。结果表明,合成的亚磷酸双十二烷基酯具有良好的极压抗磨性能,质量分数30%左右的亚磷酸双十二烷基酯,可使水基复合润滑液的最大无卡咬负荷提高75%,磨斑直径减小334%,摩擦因数降低316%,且磨痕表面相对光滑、磨痕分布均匀。

    Abstract:

    Using dibutyl phosphite and lauryl alcohol as raw materials,dilauryl hydrogen phosphate was synthesized by ester exchange method,and its structure was characterized by FTIR.A waterbased steel wire drawing lubricant was prepared with dilauryl hydrogen phosphate as extreme pressure antiwear agent and polyol esters as main oily agent,and its tribological properties were studied by fourball machine and scanning electron microscopy(SEM).Results show that dilauryl hydrogen phosphate has good extreme pressure and antiwear performance,dilauryl hydrogen phosphate with mass fraction of 30% can make the maximum nonseizure load of waterbased lubricant be increased by 75%,the friction coefficient be decreased by 316%,the wear scar diameter be decreased by 334%,and the wear scar surface is relatively smooth and the distribution of wear scar is uniform.
