| 摘 要： | 为获得性能优良的复合材料,利用辐射交联和喷雾干燥法,制备全硫化交联碳纳米管(CNT s)/粉末丁苯橡胶(SBR)复合材料,用熔融共混法对聚丙烯进行三元体系改性。结果表明:当SBR、CNT s和苯甲酸钠(相对于纯PP的质量)用量分别为15%、2%和2%时,改性后PP的冲击韧性提高了120%,拉伸强度提高了6%,扯断伸长率提高了55%,弯曲强度提高了20%。

| Abstract: | Vulcanized carbon nanotubes(CNTs) and styrene-butadiene rubber(SBR) composite powders were added to polypropylene(PP) using the melting mixing method to obtain modified composites with better properties.The powders were cross-linked using electron beam radiation and prepared using spray drying.Test results show that with an SBR loading(mass fraction to pure PP) of 15%,CNTs loading of 2%,and sodium benzoate loading of 2%,the impact strength is improved by 120%,tensile strength is improved by 6%,elongation at... |
