摘要
利用熔融插层法制备了聚丙烯(PP)/有机蒙脱土(OMMT)复合材料。利用X射线衍射仪、差示扫描量热仪、透氧仪和力学性能测试研究了OMMT对PP结构、力学性能以及透氧率的影响,并对其机理进行了分析。结果表明,加入OMMT可有效降低PP的透氧率,添加5质量份OMMT的PP复合材料透氧率可降为纯PP的30.6%。
Polypropylene (PP)/organo-montmorillonite(OMMT) composites were prepared by melting intercalation method. The effects of OMMT on the structure, mechanical properties and oxygen transmission rate of the composites were investigated by X-ray diffractometer(XRD), differential scanning calorimeter(DSC), Mocon oxygen permeability tester and mechanical property test, and the mechanism was studied. The results indicate that adding OMMT can effectively decrease the oxygen transmission rate of the PP/OMMT composites. The oxygen transmission can be reduced to 30.6% of that of pure PP in the case of 5 phr OMMT.
