不同改性剂对聚丙烯/碳酸钙复合材料性能的影响
Effect of Modifiers on the Performance of Polypropylene/Calcium Carbonate Composites
摘要
Abstract
Polypropylene/calcium carbonate-maleic anhydride-polypropylene wax (PP/CaCO3-MAH-PPW) composites were prepared by means of in situ solid phase graft copolymerization using MAH and PPW as the main raw materials.Compared with PP/pp-g-MAH/CaCO3 composites using MAH grafted with PP (PP-g-MAH) as compatibilizer,PP/CaCO3-MAH-PPW composites exhibit higher impact resistance,bending and processing properties.The results show that a good dispersion of calcium carbonate and an appropriate interface bonding between CaCO3 and PP are the key factors in order to obtain the composite with good toughness.When m (PP) ∶ m (CaCO3) =100 ∶ 20,the notched impact strength of PP/CaCO3-MAH-PPW composite reaches a maximum,which is 1.19 times as high as that of the matrix resin.关键词
