摘　　要：采用共混的方式制备了一系列添加抗氧剂的石油树脂,通过红外光谱仪、色度仪以及热重分析仪进行表征,并对石油树脂的抗老化性能进行评价。结果表明:温度的升高会促进石油树脂的老化,抗氧剂的加入能够一定程度抑制石油树脂的老化;添加抗氧剂B 215的石油树脂抗老化性能与C 100-W接近;抗氧剂B 215能够明显改善石油树脂的耐热性能。A series of petroleum resins with antioxidant were prepared by blending,and characterized by infrared spectrometer,colorimeter and thermogravimetric analyzer.The anti-aging performance of petroleum resins were evaluated.The results showed that the increase of temperature would promote the aging of petroleum resin,and the addition of antioxidants could inhibit the aging of petroleum resin to a certain extent.The anti-aging property of petroleum resin with antioxidant B 215 was close to C 100-W.Antioxidant B 215 could significantly improve the heat resistance of petroleum resins.
