| Abstract: |
| The EPDM/PP TPV composites were prepared using the complex of aluminum hydroxide，magnesium hydroxide and microencapsulated red phosphorus as halogen-free frame retardant，and adding two kinds of resins.The properties of the composites and the synergistic effect of organic montmorillonite and zinc borate were investigated.The results showed that，the flame retardance and physical properties of TPV were better due to the resin used.The vertical combustion grade of TPV could reach the V-1(sample thickness 0.8 mm)，and had better physical properties and processbility when 70 phr flame retardant was used，i.e. aluminum hydroxide/magnesium hydroxide ratio was 31.5/31.5 and microencapsulated red phosphorus was 7 phr.Organic montmorillonite and zinc borate didn’t have synergistic effect on the halogen-free flame retardant system and made physical properties bad. |
