摘要: 探讨了梭基化聚丙烯(EPP)对聚丙烯(PP) io镁石(BC)复合材料相容性的影响。SEM和流变行为测试表明,EPP增强了PP和BC的载结力,改善了两相间的相容性;BC经EPP处理后的红外谱图在884. 56 cm-1和747.68 cm-1处有吸收峰出现,证明EPP和BC间发生反应生成了梭酸镁。实验证明,EPP一方面通过梭基与BC发生化学反应;另一方面通过PP链段与PP共晶,是PP/BC复合材料的有效增容剂。采用熔融法和溶液法对BC进行表面处理所得效果明显不同,X射线衍射分析证明溶液法可使EPP在BC层结构间产生插层现象,同时力学性能和扫描电镜测试说明了溶液法优于熔融法。

Abstract: The effect of carboxyled polypropylene (EPP) on the compatibility of polypropylene (PP)/brucite(BC) composite was discussed. SEM and rheological behavior tests indicated that EPP enhanced the adhesion and improved the compatibility between PP and BC. The appearance of absorption peaks at 884. 56 and 747.68 cm一1 proved that chemical reactions took place and produced carboxyled magnesium between EPP and BC. The experiments testified that on the one hand EPP reacts with BC through carboxyl,on the other hand PP segments of EPP and PP cocrystallize, so EPP is an effective compatibilizer of PP/BC composite. The property of PP/BC composites is obviously different that BC modified with smelting method and liquor method. XRD showed that liquor method made EPP intercalate the layers of BC and the testing of mechanical property and SEM showed that liquor method exceeded melting method.
