摘要
以CPE和CPE/HPVC为改性剂 ,用熔融共混的方式对TPU的共混体系进行了系统的研究。对TPU/CPE和TPU/CPE/HPVC共混体系的力学、耐寒及流变性能进行了测试及分析。实验结果表明 :CPE及CPE/HPVC的加入 ,虽使体系的力学性能有所降低 ,但能明显改善TPU的加工性能 ,并且基本保持了TPU优异的耐寒性。
Thermoplastic polyurethane elastomer(TPU) with chlorinated polyethylene (CPE) and CPE/HPVC (high molecular weight PVC) as modifiers was studied systematically by melt blending.Mechanical properties,cold resistance and rheological behavior of TPU/CPE and TPU/CPE/HPVC blends were measured and analyzed.The results indicate that with the incorporation of CPE and CPE/HPVC,the mechanical properties of the blends decreased lightly,but the processability of TPU was significantly improved and the cold resistance of TPU was not changed basically.
