摘要： 研究納米碳酸鈣(CaCO_3)在PVC/CPE體系中的應用,討論了改進前后納米CaCO_3對PVC體系流變行為的影響,并測試了納米CaCO_3對型材性能的影響。結果表明,改進后納米CaCO_3 P100流變性接近生產試樣,可用于擠出生產;改進后的納米CaCO_3顯著提高了型材的性能,可增韌增強PVC復合體系。 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
