| 摘 要： | 通过对再生聚对苯二甲酸乙二酯(PET–R)的多次挤出,研究了扩链对PET–R稳定性的影响。同时,也通过多次挤出和多次注塑的Regrind实验,研究了丙烯腈–苯乙烯塑料接枝甲基丙烯酸缩水甘油酯(AS-g-GMA)加入后再生聚碳酸酯(PC)/PET体系的相容性和稳定性,以及熔体流动速率和冲击强度的变化。通过11个月内的生产数据反映出,经过扩链和稳定化处理后的含再生材料的PC/PET无卤阻燃合金具有很好的加工稳定性。

| Abstract: | The influence of chain extending on the stability of recycled polyethylene terephthalate (PET–R) was studied by multi-extrusion experiment. Meanwhile the changes of compatibility, stability, melt flow rate and impact strength of recycled polycarbonate (PC–R)/PET–R alloy after adding acrylonitrile-styrene grafted glycidyl methacrylate (AS-g-GMA) was discussed through multi-extrusion and multi-injection Regrind experiments. The production data of eleven months indicates that after the process of chain extending and stabilizing, the halogen-free flame retardant PC/PET alloy containing recycled materials has better stabilization. |
