The high-flashpoint jet fuel was prepared by hydrocracking jet fuel through the cutting and fractional distillation method, and the lubricity was improved by T1602 antiwear additive of naphthenic acids. The effects of the dosage of T1602, as well as the anlistatig, metal deactivator anti-ice additive on the lubricity of high-flashpoint jet fuel were studied. The results show, when the dosage of T1602 is 10.0 mg/L, the high-flashpoint jet fuel can meet the lubricity index of BOCLE method. The anlistatig, metal deactivator, anti-ice additive and T1602 have good compatibility in the high-flashpoint jet fuel, and the metal deactivator is conductive to improving the lubricity of the high-flashpoint jet fuel.通过切割、分馏等方式处理加氢裂化喷气燃料组分制备高闪点喷气燃料，并采用环烷酸类T1602抗磨添加剂改善其润滑性能。分别采用BOCLE和HFRR法考察抗磨添加剂的加入量与润滑性的关系，以及抗静电剂、金属钝化剂、防冰剂等其他添加剂的加入对高闪点喷气燃料润滑性能的影响。试验结果表明，添加10．0mg／L的T1602抗磨添加剂后，高闪点喷气燃料即可满足BOCLE评价的润滑性要求，抗静电剂、防冰剂与T1602抗磨添加剂有较好的配伍性，金属钝化剂有助于提高喷气燃料在HFRR、BOGLE测试条件下的润滑性。
