摘要： 研究纳米碳酸钙(CaCO_3)在PVC/CPE体系中的应用,讨论了改进前后纳米CaCO_3对PVC体系流变行为的影响,并测试了纳米CaCO_3对型材性能的影响。结果表明,改进后纳米CaCO_3 P100流变性接近生产试样,可用于挤出生产;改进后的纳米CaCO_3显著提高了型材的性能,可增韧增强PVC复合体系。 Use of nanometer calcium carbonate(CaCO_3)in PVC/CPE was studied,effects of nano- CaCO_3 prior and after modification on rheological behaviour of PVC sustemwere discussed and effects of nano-CaCO_3 on performance of the profile were tested.Testing results showed that rheology of the nano-CaCO_3 P100 after modification was almost the same as that of the sample.The nano-CaCO_3 P100 after modification enhanced performance of the profile could be used for extrusion to toughen PVC composite system.K
