| 中文摘要: |
| 将再生橡胶与聚丙烯（PP）熔融共混制备再生橡胶/PP共混材料，研究再生橡胶/PP共混比、共混温度、共混转子转速和增容剂DCP用量对再生橡胶/PP共混材料性能的影响。结果表明：再生橡胶/PP的共混比为70/30时，再生橡胶与PP的界面结合最好；共混温度为170 ℃时，有利于PP和填料的均匀分散；共混转子转速为60 r·min-1时，有利于提高增容剂DCP的增容效果；增容剂DCP用量为3份时，能够明显提高再生橡胶与PP的相容性，即当再生橡胶/PP的共混比为70/30、增容剂DCP用量为3份、共混温度为170 ℃、共混转子转速为60 r·min-1时，再生橡胶/PP共混材料的综合性能和微观结构最好。 |
| 英文摘要: |
| 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. |
