RDP与葫芦脲协同阻燃聚碳酸酯的研究
Study on Flame-retardant Synergy of Polycarbonate with RDP and Cucurbituril
摘要
Abstract
Flame-retardant polycarbonate (PC) compounds were prepared by combination of resiorcinol bis (diphenyl phosphate) (RDP) and cucurbituril (CB),and their flame-retardant performance was evaluated by limiting oxygen index,UL 94 vertical burning experiment and cone calorimetry.Moreover,their thermal behaviors were investigated by thermogravimetric analysis,and the morphology of their residual char was determined by SEM.The results indicated that the compounds obtained an optimum flame-retardant effect at the RDP/CB mass ratio of 6/2 and achieved an limited oxygen index of 32.5 vol %,a UL 94 V-0 classification and a heat release rate of 266 kW/m2.The combination of RDP and CB improved the thermal stability of PC and enhance its char formation effectively.The morphological observation confirmed that a dense and compact intumescent char layer was formed due to a synergy between RDP and CB,consequently enhancing the flame retardancy upon PC.关键词
