Effects of antioxidants on the properties of petroleum resins
A series of petroleum resins with an-tioxidant were prepared by blending,and character-ized by infrared spectrometer,colorimeter and ther-mogravimetric analyzer.The anti-aging performance of petroleum resins were evaluated.The results showed that the increase of temperature would pro-mote 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 im-prove the heat resistance of petroleum resins.
