STUDY ON RHEOLOGICAL PROPERTIES AND CURING PERFORMANCE OF PES/EPOXY RESIN MIXTURE SYSTEM
摘要
Abstract
Epoxy resin is a kind of thermosetting resin with good properties.However,it has the inherent weakness of poor shock resistance.Polyethersulfone (PES) is a kind of thermoplastic resin with good properties which can improve the toughness of epoxy resin by blending with epoxy resin.The rheological properties and curing performance of PES/epoxy resin mixture system with different PES content were studied systematically in this paper.A viscosity model was established according to the obtained rheological data of isothermal viscosity curves,and the mechanism of the effect of PES on the curing of PES/epoxy resin mixture system was analyzed.The influence of PES on the curing performance of PES/epoxy resin mixture system was also studied by DSC test.The results show that the dissolution of PES in epoxy resin could lead to the fluctuation of viscosity of the mixture system.The introduction of PES shortened the gel time of PES/epoxy resin mixture system,and the hydroxyl groups in PES promoted the curing of the epoxy resin.关键词
