耐高温氧化石油树脂合成技术研究

Research on the Synthesis Technology of High Temperature Oxidation Resistant Petroleum Resin

石油树脂成分比较复杂,聚合后含有大量脂环族或芳族结构,大部分仍然含有双键结构,耐高温氧化老化性能差。以除环碳九为原料,三氟化硼乙醚为催化剂,针对聚合条件催化剂用量、反应温度及反应时间等聚合条件进行考察,另外考察了抗氧剂种类和用量对石油树脂抗氧化性能的影响,通过对比石油树脂的热稳定性,得出合成耐高温碳九石油树脂的最佳聚合条件和抗氧剂的最优选择方案。

Petroleum resins are complex in composition and contain a large number of alicyclic or aromatic structures after polymerization, most of which still contain double bond structures and have poor resistance to high temperature oxidative aging. In addition, the effect of antioxidant type and amount on the antioxidant performance of petroleum resin was investigated. By comparing the thermal stability of petroleum resin, the best polymerization conditions and the optimal choice of antioxidant for the synthesis of high temperature resistant petroleum resin were obtained.
