制备了聚丙烯(PP)/改性海泡石复合材料,采用SEM、XRD、DSC、TG等测试方法对该复合材料的结构和性能进行了研究。结果表明:改性处理的海泡石在PP基材中分散均匀;少量改性海泡石的引入增大了PP的结晶度以及微晶尺寸,并且提高了PP材料的热稳定性和力学性能。
The PP / modified sepiolite composite was prepared. The structure and properties of the composites were studied by SEM, XRD, DSC and TG. The results showed that the modified sepiolite dispersed uniformly in the PP substrate. The introduction of a small amount of modified sepiolite increased the crystallinity and the crystallite size of the PP, and improved the thermal stability and mechanical properties of the PP material .
