| 摘 要： | 提出了利用无机组合粒子的协同效应增强增韧聚丙烯的新思路。硅灰石(W)、滑石(T)、重晶石(B)、碳酸钙(C)、石英(Q)与纳米氧化铝(N)等无机粒子经组合、超细并表面处理制得无机组合粒子(CIPs)；CIPs与聚丙烯(PP)混合、挤出并注射成型制备CIPs／PP复合材料标准试件，并按相应国标检测材料性能。结果表明，无机组合粒子填充PP材料的综合性能明显高于相应单一粒子填充的PP材料；纳米氧化铝的添加降低了熔体粘度，改善了填充体系的流变性能，实现了聚丙烯塑料的同时增强增韧。

| Abstract: | A new method of strengthening and toughening polymers is brought forward in the paper. The particles of wollastonite, talc, barite, calcium carbonate, quarts and nano-alumina were properly compounded, ultrafined and modified, and the fillers (CIPs) used as polypropylene reinforcement were prepared. Then the mixtures of CIPs and polypropylene resin, including some other additives, were mixed, extruded and injected into standard specimens of composites, whose properties were tested according to corresponding state standards (GB). It is found that the properties of CIPs/PP composites are much better than those of PP composites filled with corresponding single-type particles, and that nano-alumina can improve rheologic property by reducing melt viscosity and enhance the strength and toughness of PP composites simultaneously. |
