Abstract
Inorganic shell powder waste was added to recycled polypropylene(COPP), and its effect on the mechanical properties and flammability was investigated. Compatibilizer(Polytail H) was added to improve mechanical properties of COPP/shell composites. Also three different flame retardants($Al_2O_3$, DBDPO, $Sb_2O_3$) were added to improve flammability. Experimental results indicated that addition of compatibilizer resulted in an improved mechanical properties, and especially impact strength approached that of 100 wt% COPP. Addition of flame retardant did not result in decreased mechanical properties. UL-94 flammability test indicated that COPP/shell composite did not show good flame retardancy, however, in the case of COPP/shell composites containing flame retardant showed good flammability. flammability was found $Sb_2O_3>Al_2O_3>DBDPO$ in this order. Finally, UL-94 V-0 grade was found in COPP/shell composite with $Al_2O_3$, compatibilizer, and 40 wt% shell, and COPP/shell composites with $Sb_2O_3$.
