摘要
利用工业化生产中通用的橡胶混炼工艺制备了丁苯橡胶(SBR)/N330/叶蜡石基改性复合纳米粉体(PBMCN)纳米复合材料。对改性的叶蜡石基复合纳米粉体在SBR/N330/PBMCN纳米复合材料中的分散性能及对SBR/N330/PB-MCN体系纳米复合材料的力学和硫化性能的影响进行了研究。结果表明,PBMCN在SBR/N330/PBMCN复合材料中的分散效果良好。PBMCN取代N330 20%(质量分数)时,SBR/N330/PBMCN复合材料的拉伸强度、拉断伸长率及硫化性能都得到了改善。分析讨论了PBMCN在SBR/N330/PBMCN复合材料中的补强机理。
The Styrene-butadiene Rubber（SBR）/N330/ Pyrophyllite Based Modified Composite Nanopowder（PBMCN） nanocomposites were prepared by melt mixing procedure.The dispersion,mechanical and vulcanization behaviors for the effect of PBMCN on SBR/N330/PBMCN nanocomposites were studied.The results show that the PBMCN has favorable dispersibility in the matrix of SBR/N330/PBMCN nanocomposites.The tensile strength,elongation at break and vulcanization behavior are improved in SBR/N330/PBMCN nanocomposites when N330 is replaced by PBMCN for 20% mass fraction.The reinforcement mechanism of PBMCN in SBR/N330/PBMCN nanocomposites was investigated.
