STUDY ON RHEOLOGICAL PROPERTIES AND CURING REACTION KINETICS OF PEK-C/EPOXY RESIN BLEND SYSTEM

Abstract

Abstract: The epoxy resin was toughened and modified by polyetherketone cardo (PEK-C) in the paper. The rheological properties of PEK-C/E51/E100 blends with different PEK-C contents were systematically studied. The effects of different PEK-C contents on the curing reaction of blends at different heating rates were analyzed by DSC, and the apparent activation energy and curing reaction order of the curing reaction of each blend system were calculated in detail. The results show that the introduction of PEK-C shortens the gelation time of the blend system, which may be related to the promotion of the curing of epoxy resin by the hydroxyl groups in PEK-C. Meanwhile, the addition of PEK-C does not affect the curing mechanism of the epoxy resin.

Key words: PEK-C, epoxy resin, rheological properties, curing reaction kinetics
