TLCP含量对TLCP/PF复合体系固化反应动力学的影响
Effects of TLCP Contents on Curing Kinetic of TLCP/PF Blends
摘要
Abstract
The curing behaviors of thermotropic liquid crystalline polyester-imide(TLCP)/phenol formaldehyde resin(PF) blends was studied by non-isothermal DSC method. The curing kinetics of TLCP/PF blends and pure PF resins were compared and the effects of TLCP contents on the curing kinetics were investigated by three phenomenological models(including Ozawa and Kissinger simple models and Kissinger-Akahira-Sunose (KAS) isoconversional method). The results show that: the activation energy (Ea) datas of the TLCP/PF blends calculate by Kissinger consistent with Ozawa models. The curing reaction of PF is affected and the Ea is changed with the addition of TLCP. When TLCP content is 3%, the Ea of TLCP/PF blends is minimum.关键词
