| 摘 要： | 将氢氧化铝(ATH)作为阻燃剂与聚乳酸(PLA)、竹粉(BF)共混,得到PLA/BF/ATH阻燃复合材料,并对该复合材料的性能进行了测试与表征。结果表明:随着ATH用量的增加,PLA/BF/ATH阻燃复合材料的力学性能有所降低,但复合材料的热稳定性和残炭率相对提高,而且ATH的引入对复合材料燃烧过程中热量和烟气的释放产生了一定的抑制作用;另外,当ATH用量为25 phr时,复合材料具有最佳综合性能。

| Abstract: | Flame retardant polylactic acid/bamboo flour/aluminium hydroxide(PLA/BF/ATH) composite was prepared by using ATH as flame retardant,and the performance of the composite was tested and characterized.The results show that the mechanical properties of the PLA/BF/ATH composite decrease with the increase of ATH content,but the thermal stability and char residue rate of the composites increase,and ATH shows a certain inhibition on the heat and smoke release of the composites during the combustion.Moreover,the composite has the optimal comprehensive performance when ATH content is 25 phr. |
