Improving Flame Retardancy of IFR/PP Composites Through The Synergistic Effect of Organic Montmorillonite Intercalation Cobalt Hydroxides Modified by Acidified Chitosan
To improve flame retardancy of IFR/PP composites, organic montmorillonite (Mt) intercalation cobalt compounds (Co-OMt) were prepared and modified by acidified chitosan.The Co-OMt/IFR/PP nanocomposites were fabricated via melt blending method.With addition of 4 mass% Co-OMt, 4 mass% Co-OMt/IFR/PP nanocomposites passed UL-94 V-0 rating and the LOI value was high to 32.1%.Furthermore, the cone calorimeter tests results confirmed that peak heat release rate (PHRR), of 4 mass% Co-OMt/IFR/PP nanocomposites decreased by 16.7 % compared with those of IFR/PP composites.The notably improved flame retardant were attributed to the fine dispersion of Co-OMt with layered structure and excellent catalytic performance in PP matrix, which promoted the fully cover of consolidated and compact residual layers on the surface of polymer during combustion, ultimately suppressing heat and mass transfer between polymer matrix and flame zone.
