摘要: 应用两种分散剂(Altfona 3050和Altfona 3020)制备了聚丙烯/炭黑(PP/CB)复合材料,在PP中添加8份CB和2份分散剂1时,PP/CB分散剂1复合材料的体积电阻率从8. 25 * 10' 16下降至1. 08 *10'6,得到了静电消除材料。分散剂1和2在降低PP/CB复合材料体积电阻率的同时,对基体材料的拉伸强度影响不大。扫描电子显微镜分析表明,在PP/CB复合材料中,CB在分散剂1的良好润湿下的分散粒径达到纳米尺度。

Abstract:

Two kinds of dispcrsants,Altfona 3050 and ALTFONA 3020 were introduced into polypropylene(PP) /carbon black(CB) composites to improve the dispersion of CB. When the contents of CB and Altfona 3050 were 8 phr and 2 phr, respectively, the composite gave a volume resistivity of 1 .08 X 10 cmwithout a loss in tensile strength. Scanning electron microscope(SEM) showed that Altfona 3050 couldpromote the dispersion of CB in a nano-scale in PP.
