| Abstract: |
| The recycled rubber/polypropylene（PP） blends were prepared by melt blending of recycled rubber and PP，and the effects of the recycled rubber/PP blending ratio，blending temperature，blending rotor speed and compatibilizer DCP amount on the properties of recycled rubber/PP blends were studied.The results showed that，when the reclaimed rubber/PP blending ratio was 70/30，the interface combination of rubber and plastic was the best.When the blending temperature was 170 ℃，it was beneficial to the uniform dispersion of PP and fillers.When the blending rotor speed was 60 r·min-1，it was beneficial to improve the compatibilizing effect of compatibilizer DCP.When the compatibilizer DCP amount was 3 phr，it could significantly improve the compatibility of reclaimed rubber and PP.The reclaimed rubber/PP blends had the best overall properties and microstructure when the blending ratio of reclaimed rubber/PP was 70/30，the amount of compatibilizer DCP was 3 phr，the blending temperature was 170 ℃，and the blending rotor speed was 60 r·min-1. |
