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B215的石油树脂抗老化性能与C100-W接近;抗氧剂B 215能够明显改善石油树脂的耐热性能.
Abstract
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.
