摘要
Abstract
In this study,Co-LDH@ZIF-67 composite structure was constructed in situ using Co-LDH as a carrier,which effectively improves the defects of low catalytic activity and low specific surface area of Co-LDH.The flame retardancy tests showed that the Co-LDH@ZIF-67 modified epoxy(EP)composites had significant advantages in suppressing heat,smoke,and toxic gases compared to Co-LDH.Specifically,the LOI value of the composites increased from 24.5%to 28.2%when Co-LDH@ZIF-67 was added at 2 wt%.The peak heat release rate,the total heat release,and the total smoke release of the EP/Co-LDH@ZIF-67 composites were reduced by 35.1%,16.3%,and 15.8%,respectively,compared with pure EP.And it has more obvious flame retardant and smoke suppression ability compared with Co-LDH.关键词
