摘要
Abstract
In this study,DOPO-DBA-F as a flame-retardant cross-linking agent was introduced into the bismaleimide res-in as a raw material to prepare a modified material with both self-healing and flame-retardant properties.The structure and performance of the modified material was characterized by using Fourier-transform infrared spectroscopy,thermogra-vimetry analysis,differential scanning calorimetry(DSC),polarized light microscopy,limiting oxygen index meter,ver-tical burning experiment,and cone calorimetry.The morphology of the residual char was observed by scanning electron microscopy.The results indicated that the formation of reversible Diels-Alder(DA)bonds effectively improved the recy-clability of the bismaleimide resin.The presence of the reversible DA bonds between the furan groups and bismaleimide resin was confirmed by DSC.Meanwhile,the introduction of flame-retardant cross-linking agent successfully improved the flame-retardant properties of the modified material,resulting in a limiting oxygen index of 38.5%and a UL94 V-0 rating in the vertical burning experiment.关键词
