This work explores a novel blend of recycled polyethylene terephthalate/polyamide 11 (rPET/PA11). The blend of rPET/PA11 was introduced to enhance the mechanical properties of rPET at various ratios. The work’s main advantage was to utilize rPET in thermoplastic form for various applications. Three different ratios, i.e. 10, 20 and 30 wt.% of PA11 blend samples, were prepared using a twin-screw extruder and injection moulding machine. The mechanical properties were examined in terms of tensile, flexural and impact strength. The tensile strength of rPET was improved more than 50%, while the increase in tensile strain was observed 42.5% with the addition of 20 wt.% of PA11. The improved properties of the blend were also confirmed by the flexural strength of the blends. The flexural strength was increased from 27.9 MPa to 48 MPa with the addition of 30 wt.% PA11. The flexural strain of rPET was found to be 1.1%. However, with the addition of 10, 20 and 30 wt.% of PA11, the flexural strain was noticed as 1.7, 2.1, and 3.9% respectively. The impact strength of rPET/PA11 at 20 wt.% PA11 was upsurged from 110.53 to 147.12 J/m. Scanning electron microscopy analysis revealed a dispersed PA11 domain in a continuous rPET matrix morphology of the blends. This work practical implication would lead to utilization of rPET in automobile, packaging, and various industries.

一种新型的再生对苯二甲酸乙二酯/聚酰胺11(rPET / PA11)热塑性共混物

这项工作探索了一种再生的对苯二甲酸乙二醇酯/聚酰胺11(rPET / PA11)的新型混合物。引入了rPET / PA11的共混物以增强rPET在各种比例下的机械性能。这项工作的主要优势是将热塑性塑料的rPET用于各种应用。使用双螺杆挤出机和注射成型机制备三种不同比例的PA11共混物样品,分别为10、20和30 wt。%。根据拉伸强度,弯曲强度和冲击强度检查了机械性能。rPET的拉伸强度提高了50%以上,而添加20 wt。%的PA11则使拉伸应变提高了42.5%。共混物的抗弯强度也证实了共混物的改善的性能。弯曲强度从27增加。9 MPa至48 MPa,添加30 wt。%PA11。发现rPET的弯曲应变为1.1%。然而,在添加10、20和30重量%的PA11时,弯曲应变分别为1.7%,2.1%和3.9%。rPET / PA11在20 wt。%PA11时的冲击强度从110.53提高到147.12 J / m。扫描电子显微镜分析显示共混物的连续rPET基质形态中分散的PA11结构域。这项工作的实际意义将导致rPET在汽车,包装和各种行业中的应用。扫描电子显微镜分析显示共混物的连续rPET基质形态中分散的PA11结构域。这项工作的实际意义将导致rPET在汽车,包装和各种行业中的应用。扫描电子显微镜分析显示共混物的连续rPET基质形态中分散的PA11结构域。这项工作的实际意义将导致rPET在汽车,包装和各种行业中的应用。
