摘要
对苯并(?)嗪／酚醛共混树脂的反应特性进行了研究,包括共混树脂的粘温特性、反应动力学参数的计算、共固化机理等。结果表明:苯并(?)嗪树脂与酚醛树脂几乎能以任意比例混合固化;苯并(?)嗪质量分数为40％的共混树脂FBZ／4,其粘温特性和DSC分析表明,反应活性优于其它几种共混树脂。
Reaction of benzoxazine /phenolic mixed resin is investigated . Viscosity-temperature characteristics, kinetics of reaction and co-reaction mechanisms of the mixed resins are studied. Experimental results indicate that the benzoxazine resin may be mixed at almost any ratio with phenolic resin. Mixed resin FBZ/4 with 40% of the benzoxazine presents high reactivity compared with other ratio mixed resins by viscosity-temperature characteristics and DSC analysis.
