表面改性Sb2O3对阻燃ABS/DBDPE/Sb2O3复合材料性能的影响
Effect of surface modified Sb2O3 on properties of flame-retardant ABS/DBDPE/Sb2O3 composites
摘要
Abstract
Four surface modifiers,NDZ-201,GR-A118,KH-550 and DPAK,were used to modify Sb2O3 particles by wet ball milling.The structure and morphology of Sb2O3 before and after modification were characterized by FTIR,XRD and SEM.ABS/DBDPE/Sb2O3 composite was prepared by extrusion granulation and injection molding.The ef-fect of Sb2O3 modified by four surface modifiers of 2%on the composite properties was studied.The results show that Sb2O3 modified by four surface modifiers has a certain effect on the comprehensive properties of the composite.After sur-face modification,the machinability of the composite is obviously improved.After modification,good flame retardancy and thermal properties are maintained,and all vertical combustion passes the UL 94 V-0 grade.After modification,the mechanical properties are improved in different degrees,and the impact properties are improved obviously.The NDZ-201-modified composite presented impact strength of 46.99 kJ/m2.This result is 36.01%higher than the impact strength of unmodified composite.Moreover,the bending strength of the modified composite was also improved to some extent.NDZ-201 and DPAK exhibit good modification effect,facilitating an improvement in the machining and mechani-cal properties of composites.关键词
