赛克阻燃应用研究进展OA北大核心

The flammability of polymer materials is a crucial problem to be solved in industrial applications.THEIC,a fine chemical material composed of C,N,O and H containing azine ring structure,is endowed with excellent chemical stability,thermal stability and carbonization effect,and is often used as the carbon source of intumescent flame retardant(IFR).However,THEIC has defects such as unstable processing,poor flame retardant effect alone,high water solubility,and easy migration,which limit its further development.Therefore,the physicochemical properties and preparation methods of THEIC are introduced in this paper,and the flame retardant application of THEIC in polypropylene,polyethylene,epoxy resin and other polymer materials is emphasized.In particular,the molecular structure design and morphological changes of THEIC,flame retardant mechanism and the performance of flame retardant materials have been systematically discussed.Finally,the future development direction of THEIC is prospected,pointing out that developing new modification methods,researching efficient flame retardant formulations,improving processing stability,developing nanocomposite flame retardants,expanding flame retardant application fields and multifunctional applications are the main development directions of THEIC in the future.
