| Abstract: |
| Polypropylene(PP) fine powders were prepared by solid state shear milling and high speed disintegrating methods，and the micro state of two kinds PP fine powders and the influence of PP fine powder on the structure and properties of carbon black/NR composites were investigated.The results showed that，the shape of solid state shear milled PP fine powder was more irregular，the particle size was smaller，the surface energy was higher，the compatibility with NR was better and the reinforcing effect was more prominent compared with high speed disintegrated PP fine powder.PP fine powders were dispersed homogeneously in NR matrix without affecting the dispersion of carbon black in NR matrix while the addition level of PP fine powder was lower，the curing characteristics，tensile properties，hot air aging properties and dynamic properties of carbon black/NR composites were improved with small amount of PP fine powder. |
