摘要: 通过实验对比研究了改进型二丁基二硫代氨基甲酸酯(ADMC)与其它同类添加剂的性能差异,并采用高压差示扫描量热法考察了ADMC添加剂与胺类抗氧剂对,对二辛基二苯胺(DODPA)在聚-?-烯烃合成润滑基础油中的热氧化安定性。结果表明:ADMC添加剂在矿物基础油中表现出了良好的油溶性、摩擦学性能和抗腐蚀性能;虽然ADMC添加剂的抗氧化性明显差于DODPA抗氧剂,但ADMC与DODPA添加剂复配后,可明显提高润滑油的起始氧化温度,延长氧化诱导时间,二者表现出了良好的抗氧协同效应。

Abstract: The performances of novel dibutyl dithiocarbamate (ADMC) in mineral base oil are investigated comparing with the same type of additives. The results show that ADMC exhibits good oil solubility, tribological properties, and corrosion resistance. Meanwhile, the thermal oxidation stability of ADMC and p,p-dioctylphenylamine (DODPA) in Poly-a-olefin synthetic base oil is evaluated by pressure differential scanning calorimetry (PDSC). The results show that DODPA possess better antioxidant properties than ADMC, the initial oxidation temperature and extends oxidation induction time of PAO containing DODPA are improved obviously when ADMC was combined with DODPA. Accordingly, they exhibit good antioxidant synergistic effects.
Key words: dibutyl dithiocarbamate, p,p-dioctylphenylamine, antioxidant, synergistic effects
