摘要
用差示扫描量热(DSC)法研究PP/GF/HDPE复合物熔融试样的冷却过程,同时采用偏光显微镜技术观察复合物的形态结构。试验表明PP/GF/HDPE复合物的结晶峰温度升高8～9℃,结晶起始斜率变大,球晶几何尺寸明显减小,复合物中的玻璃纤维(GF)起到异相成核作用,高密度聚乙烯(HDPE)对聚丙烯(PP)有增塑作用并对异相成核具有协同效应。
This paper describes cooling crystal exothermic diagrams of melt spcimen by Differential Scanning Calorimentry (DSC) , by using microscope analyses morphological structure. It was iound in the experiment that the glass fiber (GF) made crystal peak temperature raise 8~9 ℃, Crystal original taper to be large, spherocrystal size small, it -acted the function of hetero-geneous nucleation for polypropylene (PP) . High density polyethylene (HDPE) has plasticizing efficancy and combined effect of hetero-geoeous nucleation for PP.
