摘要
综合利用粉煤灰可以减少污染和循环利用资源,制备了粉煤灰填充改性PVC复合材料。文章研究了PVC/粉煤灰微珠复合材料的流变性能;通过优化配方,研究了PVC/粉煤灰微珠复合材料的力学性能;实验结果表明:当粉煤灰微珠添加量在5～10份之间时,塑化时间75～87 s以内,利于PVC干混料的塑化和后期加工;当粉煤灰微珠为5份时,PVC/粉煤灰微珠复合材料的悬臂梁缺口冲击强度最好为46 kJ/m2,拉伸强度达到最大值42.7 MPa。粉煤灰协同CPE增韧PVC复合材料。
Abstract：The comprehensive utilization of fly ash was to reduce pollution and recycling use of resources. Fly ash filled and modified PVC composite was made. The rheological properties of PVC/fly ash bead composite were studied. By optimizing the formulation, the influence of fly ash bead on the mechanical properties of composite materials was studied. The results showed that when the fly ash bead dosage between 5 - 10 parts,plasticizing time within the 75 ~ 87 s,which was conducive to the PVC dry mixing of the plasticized and post-processing, When fly ash beads were 5 parts,the PVC/fly ash bead composite izod notched impact strength was best for 46 kJ/m2. Tensile strength reached the maximum value of 42.7 MPa, PVC composite was toughened by fly ash and collaborative CPE,
