摘要： 利用差示扫描量热法分析了烯丙基酚醛树脂在不同升温速率下的固化行为,用Kissinger法和KAS(Kissinger-Akahira-Sunose)法对获得的动力学数据进行处理,得到了固化反应动力学参数,并建立了烯丙基酚醛树脂的固化动力学模型.结果表明:与纯酚醛树脂相比,烯丙基酚醛树脂固化温度较高,反应级数更接近于1,固化反应所需的平均表观活化能较低,为111.45kJ/mol;在整个固化过程中,烯丙基酚醛树脂的活化能较为恒定,随温度变化不大;烯丙基酚醛树脂固化动力学模型为研究该体系固化工艺参数提供了理论依据.

Abstract: The curing behavior of allyl phenolic resin was analyzed at different heating rates using differential scanning calorimetry. The obtained kinetic data were treated by Kissinger and KAS(Kissinger-Akahira-Sunose) methods to obtain the curing reaction kinetic parameters. A curing kinetics model was established for allyl phenolic resin. Compared with phenolic resin, the curing temperature of allyl phenolic resin is higher, the reaction order is closer to 1, and the average activation energy of the curing reaction is lower, 111.45 kJ/mol. The activation energy of allyl phenolic resin is almost constant and changes little with temperature in the curing process. The curing kinetics model of allyl phenolic resin provides a theoretical basis for the study of curing process parameters.
