摘要
对比研究了直立式医用聚丙烯输液袋专用粒料(ZYL)与其它4种粒料PTL、GXL-01、GXL-02和GXL-03的性能,并用差示扫描量热仪(DSC)研究了5种粒料的熔融和结晶行为。结果表明,ZYL的熔点和结晶度都稍低于另外4种粒料。力学性能测试表明,ZYL所得样条的韧性提高,断裂伸长率和缺口冲击强度较PTL分别提高了81.7%和120.0%。光学性能和熔融指数测试表明,ZYL保留了很好的透光性(89.7%),同时流动性较好,利于产品的加工成型。扫描电镜(SEM)照片表明,ZYL的基材与改性剂间的界面结合力更好。ZYL综合性能较PTL以及另外3种粒料优异;同时,生物安全性能符合规定,在聚丙烯输液袋产品中具有较好的应用前景。
In this study, special polypropylene granules （ZYL） were investigated and compared with other four granules, including PTL, GXL-01, GXL-02 and GXL-03. The melt and nonisothermal crystallization behavior were investigated by DSC. The results indicate that the melting peak and crystallinity of ZYL are lower than those of other four kinds of granules. The results of mechanical property indicate that the toughness of ZYL increases and the elongation at break and impact strength increase by 81.7% and 120.0%, respectively. The results of optical property and melt index show that ZYL retains a good light transmission （89.7 % ）, and the good fluidity of ZYL is benefit to the moulding process. The SEM images show that the binding force between substrates and modifiers of ZYL is the strongest. In addition, the special granules ZYL show a good biocompatibility. And the special granules possess good prospects to be used as polypropylene infusion bags.
