聚丙烯酸酯流变性能的研究
Rheological Properties of Actylic Polymer
-
摘要: 用Instron3211型毛细管流变仪研究了文题,讨论了醋酸锌,苯甲酸衍生物及硅砂对聚丙烯酸酯熔体粘度的影响。结果表明,聚丙烯酸酯熔体是非牛顿流体,其流动活化能随剪切速率的增大而减小,加入醋酸锌后,粘度有明显的提高,而同时加入等摩尔的醋酸锌和苯甲酸衍生物后,粘度保持不变,加入硅砂后,粘度有所提高。Abstract: The rheological properties of acrylic polymer have been determined by usingInstron 3211 model capillary rheometer under various temperatures. Influencesof zinc acetate,derivants of benzoic acid and SiO_2 on viscosity of acrylic polymer were dis-cussed.
