| 摘 要：合成了兩種雙-（（2-二烷基氨基硫羰基硫）乙酸）1，4-丁二酯化合物。研究了其作為潤滑油添加劑的熱穩定性及其在液體石蠟（LP）中的溶解性和銅片腐蝕性；在四球摩擦機上考察了其承載能力和抗磨性能。結果表明，兩種化合物都具有優(yōu)良的熱穩定性、油溶性和抗腐蝕性能，且能夠明顯提高液體石蠟的承載能力和抗磨性能。添加質(zhì)量分數為1.0%的化合物的油樣的最大無(wú)卡咬負荷（PB）值比液體石蠟提高了106%，磨斑直徑比液體石蠟減小了42%。 |

| Abstract：Two kinds of double-(2-sulfur dialkyl amino carbonyl sulfide) acetic acid) 1,4-butyl ester compounds for lubricant additives were prepared. The thermal stability, solubility and corrosion resistance in liquid paraffin (LP) of these compounds as lubricating oil additive were also studied. The carrying capacity and anti-wear performance were investigated on a four-ball machine. The results showed that both additives have excellent thermal stability, oil solubility and corrosion resistance, which could significantly improve the carrying capacity and anti-wear properties of liquid paraffin. The maximum non-seizure load (PB) value of oil sample with a loading of 1.0% was 106% higher than that of non-added liquid paraffin, the wear scar diameter was reduced by 42% compared with that of liquid paraffin. |
| Key words：lubricant additives; ester; carrying capacity; anti-wear performance |
