| 摘 要： | 用熔融挤出法制备了丙烯酸(AA)改性纳米CaCO3／PP母料及复合材料,系统研究了两种粒径的纳米CaCO3、单体AA和引发剂DCP的用量,以及制备母料的不同基体对纳米CaCO3／PP复合材料力学性能的影响。结果表明纳米CaCO3／PP复合材料的力学性能高于微米CaCO3／PP复合材料,纳米CaCO3对PP有增强增韧作用。在制备母料过程中加入AA,有助于进一步提高纳米CaCO3／PP复合材料的力学性能。加入少量DCP也有利于提高复合材料的力学性能。制备母料的基体为粉状PP的力学性能高于粒状PP。

| Abstract: | Nano-CaCO 3/PP masterbatch modified with AA and nano-CaCO 3/PP composites were prepared by melt extrusion.This paper systematically investigated the effect of the content of nano-CaCO 3 with two kinds of particle sizes,AA and DCP,and the matrix of masterbatch on mechanical properties.The results showed that the mechanical properties of nano-CaCO 3/PP composites were higher than those of micro-CaCO 3/PP composites.Modification of AA further increased the mechanical properties of nano-CaCO 3/PP composites.In the preparation of the nano-CaCO 3/PP masterbatch,addition of a few of DCP was helpful to improve the mechanical properties of composites.The mechanical properties of composites prepared with the masterbatch prepared by powdered PP were higher than those of masterbatch prepared by pelletized PP. |
