摘要：
PP/OMMT-DBDPE/Sb2O3 composite, based on the partial replacement of decabromodiphenyl ethane (DBDPE) by organic montmorillonite (OMMT), was prepared by melt blending method. Scanning electron microscope (SEM), thermogravimetric analysis (TGA) and cone calorimeter were used to characterize the structure features, thermal stability and flame retardancy of the composites. The results showed that the onset temperature and decomposition temperature of PP/11.25%OMMT-11.25%DBDPE/7.5%Sb2O3 composite increased by 8℃ and 13℃ respectively compared to PP/22.5%DBDPE/7.5%Sb2O3 composite. The amount of nonvolatile residue of PP/11.25%OMMT-11.25%DBDPE/7.5%Sb2O3 composite at 600℃ was 13.71%, 3.96% higher than that of PP/22.5%DBDPE/7.5%Sb2O3 composite. The peak heat release rate (PHRR) of PP/11.25%OMMT-11.25%DBDPE/7.5%Sb2O3 composite was 374 kW/m2, 19% lower than that of PP/22.5%DBDPE/7.5%Sb2O3 composite. The fire performance index (FPI) of PP/11.25%OMMT-11.25%DBDPE/7.5%Sb2O3 composite was 0.185 s·m2/kW, 36% higher than that of PP/22.5%DBDPE/7.5%Sb2O3 composite. The thermal stability and flame retardancy of the PP composites are improved sharply because of the partial replacement of DBDPE by OMMT. © 2016, Materials Review Magazine. All right reserved.
