摘　　要：导热油中加入不同类型抗氧剂后进行热稳定性试验(320℃),并进行馏程分析。通过对比馏程,研究了4种类型抗氧剂对导热油热稳定性的影响,结果表明,添加高温抗氧剂可以大幅度提高导热油的热稳定性能,高温抗氧化能力由强到弱顺序依次为:苯氨型抗氧剂与硫醚型抗氧剂复合剂、苯胺型、萘胺型、酚型、苯氨型抗氧剂与硫醚型抗氧剂的复合剂,可以大幅降低导热油的变质率。Heat transfer oil thermal stability tests(320℃)were conducted by adding different types of antioxidants,and the distillation ranges were analyzed.The effects of 4 types of antioxidants on the thermal stability were studied by comparing the distillation ranges.The results show that the addition of high-temperature antioxidants can greatly improve the thermal stability of heat transfer oil.High-temperature antioxidant capacity from strong to weak:phenylamine antioxidant and thioether antioxidant compound>aniline antioxidant>naphthylamine antioxidant>phenolic antioxidant.The phenylamine antioxidant and thioether antioxidant compound can greatly reduce the deterioration rate of heat transfer oil.
