PA6/PA6I共混物的制备及性能
|
摘要
采用双螺杆挤出机制备了聚酰胺6 (PA6)/聚间苯二甲酰己二胺(PA6I)共混物,对不同配比的PA6/PA6I共混物进行了力学性能、成型收缩率、吸水率、透光率、耐车用尿素溶液性能的研究。结果表明,随着PA6I含量的增加,PA6/PA6I共混物的拉伸强度、弯曲强度逐步增大,而断裂伸长率、简支梁缺口冲击强度先降低后升高,在PA6I含量为15%时,二者均出现最小值;共混物的成型收缩率、吸水率随着PA6I含量的增加逐步降低,在PA6I含量为45%时,成型收缩率降低了46.0%、吸水率降低了51.2%;共混物的透光率、耐尿素溶液的能力随着PA6I含量的增加逐步增大,在PA6I含量为45%时,透光率达到70%,在车用尿素溶液中浸泡72h后,共混物的拉伸强度保持率、弯曲强度保持率分别达到84.1%,77.4%,比纯PA6的相应性能分别提高了16.5%,16.0%。
Polyamide 6(PA6)/poly(hexamethylene isophthalamide)(PA6I) blends were prepared using a twin screw extruder. Mechanical properties,molding shrinkage,water absorption rate,transparency and the resistance for vehicle urea solution of PA6/PA6I blends of different proportions were investigated. The results show that the tensile strength and blending strength of the blend increase,the Charpy notched impact strength and the elongation at break decrease first and then increase with increasing PA6I content. When the PA6I content is 15%,the Izod notched impact strength and the elongation at break both have a minimum value.The molding shrinkage and water absorption rate decrease with increasing PA6I content. When the PA6I content is 45%,the molding shrinkage and water absorption rate decrease by 46.0% and 51.2%,respectively. The transparency and the resistance for vehicle urea solutionof the blends increase with increasing PA6I content. When the PA6I content is 45%,the transparency is 70%. After the blend is soaked in vehicle urea solution for 72 h,the tensile strength retention and blending strength retention of the blend reach 84.1% and 77.4%,which is 16.5% and 16% respectively higher than the corresponding performance of the pure PA6.
