| 摘 要： | 应用自制的接枝共聚相容剂（马来酸酐接枝聚乙烯或马来酸酐接枝乙烯辛烯共聚物）将回收聚对苯二甲酸乙二醇酯（PET）与回收聚乙烯（PE）共混改性，再挤出成型，研制出PET/PE合金管材。结果表明，该PET/PE合金管材不仅具有完美的外观和较低的价格，更具有良好的性能，拉伸强度为33.2 MPa，断裂伸长率为151 %，冲击强度为40.3 kJ/m2，维卡软化温度为81.2 ℃，环刚度为5.1 kN/m2； 该PET/PE合金管材的加工不需要对PET瓶片进行烘干处理。

Development of PET/PE Alloy Tubes Made of Recycling Polyester Bottles |
| |
| Abstract: | A self made compatibilizer was used in blends of recycling PET and PE, and the PET/PE alloy tubes was developed. The tube not only has a perfect appearance and low price, but also good properties, including the tensile strength of 33.2 MPa, elongation at break of 151 %, impact strength of 40.3 kJ/m2, Vicat softening temperature(A50) of 81.2 ℃, and ring stiffness of 5.1 kN/m2. In addition, PET/PE alloy pipes could be processed without pre drying. |
