摘要:
为研究不同代数超支化聚酯酰胺(HBPEA)在尼龙6加工中的影响,以4-甲基六氢苯酐(MHHPA)和二异丙醇胺(DIPA)为原料,通过一步法熔融聚合的方式,制备了2种不同代数的超支化聚聚酯酰胺(HBPEA),并将其作为加工助剂与尼龙6(PA6)在双螺杆挤出机中共混。通过红外光谱、热失重分析仪、乌式黏度计分析了两种HBPEA的结构和热稳定性。通过对力学性能、流变行为的测试,研究了HBPEA质量分数对PA6的影响。结果表明:两种不同代数HBPEA的添加,都可以提升HBPEA/PA6共混物的流动性能和机械性能,其中,高代数HBPEA/PA6共混物的提升效果更好。当高代数HBPEA质量分数为1%时,高代数HBPEA/PA6共混物拉伸强度和弯曲强度达到最大值,分别为61.3、183.3 MPa。
Abstract:
To investigate the effects of hyperbranched poly(ester amide)s (HBPEA)with different generations on processing of nylon 6 (PA6), two HBPEAs with different generations were prepared with hexahydro- 4-methylphthalic anhydride (MHHPA) and diisopropanolamine via one-step melt polycondensation. HBPEA was then used as a modification agent to process nylon 6 (PA6) using a twin-screw extruder. The resulting HBPEAs were characterized by Fourier transform infrared spectroscopy, thermo gravimetric analyzer and ubbelohde viscometer. The effects of HBPEAs on properties of nylon 6 were investigated by testing mechanical properties and rheological behavior. It is found that the HBPEA can improve the processing fluidity and mechanical properties of PA6, especially, the PA6 modified by HBPEA with higher generation shows better processing fluidity and mechanical properties. The tensile strength and flexural strength of the PA6 reach a maximum of 61.3 MPa and 183.3 MPa respectively when the mass fraction of HBPEA with higher generation is 1%.
