| 摘 要： | 将废旧瓦楞纸板粉碎制浆，与HDPE（高密度聚乙烯）通过模压成型制备了废纸浆/HDPE发泡复合材料。利用英国Rosand双料筒毛细管流变仪，在线研究了发泡剂AC含量、废纸浆含量、温度以及吸热、放热和平衡发泡剂对废纸浆/HDPE复合发泡材料的流变行为的影响，并在SEM下观察了不同AC含量和废纸浆含量对发泡形态的影响。结果表明：废纸浆/HDPE复合发泡材料熔体表现为假塑性流动特征，当剪切速率达到600 s-1时，出现管壁滑移现象。发泡剂AC能明显降低熔体黏度，随着AC含量的增加，熔体黏度下降。随着废纸浆含量的增加，熔体黏度增加。当剪切速率小于275 s-1时，随着温度的升高，熔体黏度降

| Abstract: | Waste corrugated board was ground to paper pulp,which was used to prepare the foamed waste paper pulp/high density polyethylene(HDPE)composites by compression molding with HDPE.The Rosand double-barrel capillary rheometer was used to study the influences of the blowing agent AC (azodicarbonamide)content,waste paper pulp content,temperature and different blowing agents on the melt of the composites.Scanning electron microscopy(SEM)was also used to observe the effects of different contents of AC and waste pap... |
