摘要
为探讨GTL基础油与常用极压抗磨剂感受性,分别将二烷基二硫代磷酸锌(T203)、磷酸三甲酚酯(T306)、二烷基二硫代氨基甲酸钼(S-525)、钼胺络合物(MOLYVAN 855)、硫磷酸复酯胺盐(T307)、硫化异丁烯(T321)和合成酯(VANLUBE 7723)与GTL基础油进行调配,利用四球摩擦试验机分别考察单剂和复配后油样的最大无卡咬负荷、磨斑直径和摩擦因数。结果表明:T307、MOLYVAN 855在GTL基础油中极压性和抗磨性最优;T203和VANLUBE 7723复配、T203和MOLYVAN 855复配对GTL基础油极压性和抗磨性能提升明显,而T203和S-525复配具有最佳的减摩效果;T306分别和S-525、T307和T321复配时表现出的极压性能变化趋势相似,而T306和T307复配在表现出良好极压性能的同时,兼具有较好的减摩抗磨效果。
In order to investagate the sensitivity of GTL base oil and common extreme pressure antiwear agents,the additives of Zinc dialkyldithiophosphate(T203),tricresoll phosphate(T306),molybdenum dialkyldithiocarbamate(S-525),molybdenum amine complex(MOLYVAN 855),thiophosphate complex(T307),isobutene sulfide(T321)and synthetic ester(VANLUBE 7723)were mixed with GTL base oil respectively,and the maximum non-seizure load,wear scar diameter and friction coefficient of oil samples after single additive and compound additives were investigated by four-ball test rig.The results show that T307 and MOLYVAN 855 have the best extreme-pressure and anti-wear properties in GTL base oils.The combination of T203 and VANLUBE 7723 and T203 and MOLYVAN 855 significantly improves the extreme-pressure and anti-wear properties of GTL base oil,while the combination of T203 and S-525 has the best friction reduction effect.When T306 blends with S-525,T307 and T321 respectively,the extreme-pressure performance is similar.While the blending of T306 and T307 show good extreme pressure performance and good friction reduction and anti-wear effect.
