环氧树脂与氰酸酯共固化产物性能的研究

The influence of composition on the curing kinetic parameter,electrical,mechanical,thermal properties and the glass transition temperature of cured compound of epoxy and cyanate ester co\|curing system catalyzed by transition metal acetylacetone was studied by means of DSC,dielectric and dynamic mechanical methods in this paper.The results showed that the reactive energy and frequency factor of co\|curing is found to increase with enhanced concentrations of cyanate ester of co\|curing system.The glass transition temperature and thermal stability of cyanate ester and epoxy cured system is found to increase with enhanced concentrations of the cyanate ester under the same cured condition,addition of the cyanate ester will decrease the loss factor and dielectrical constant value as well.
