摘要
主要研究了加工工艺对PP/弹性体/纳米CaCO3三元复合材料的力学性能的影响。发现经二阶共混后材料的力学性能明显优于一阶共混。在二阶共混时,分别以PP和弹性体为载体,制备两种不同核-壳结构的CaCO3母粒。结果表明:相同纳米CaCO3质量含量时,以PP为载体的母粒所制得的材料的冲击强度明显高于以弹性体为载体的母粒所制得的材料;以极性弹性体为母粒载体所制得的材料的冲击强度优于以非极性弹性体母粒载体所制得的材料。
Effects of processing technology on mechanical properties of PP/Elastomer/nano-CaCO3 ternary composite were studied. It was found that mechanical properties of material which after binary blends was better than after direct bland. Two different kinds core-shell structure of particle were also studied, one used the elastomer as the particle carrier,the other used PP as the particle carrier. Influence of impact strength of composite by different polar of elastomers was studied. It was showed that the mechanical properties of the composite which used PP as carrier of nano-CaCO3 particles was better than the mechanical properties of the composite which used elastomer as carrier of nano-CaCO3 particles;the impact strength of composite which polar elastomer was used as cartier of nano-CaCO3 particles was better than nonpolar elastomer was used as carrier of nano-CaCO3 particle.
