摘要
将氢化苯乙烯-丁二烯嵌段共聚物(SEBS)和聚丙烯(PP)与(聚乳酸) PLA共混改性,得到改性复合材料。分析复合材料的物理性能和力学性能,并将复合材料应用于加热不燃烧烟气降温。结果表明,两者均未改变PLA的晶型结构,且SEBS比PP更能增强PLA韧性、拉伸性能和冲击强度,但共混材料分解能力有所下降。SEBS+PLA复合材料具有更好的纺丝性能和加热不燃烧烟气降温效果。
Styrene-ethylene-butylene-styrene(SEBS) and polypropylene(PP) were blended with poly(lactic acid)(PL A) and the modified composites were obtained.The physical and mechanical properties of composite materials were analyzed and the composite materials were applied to heat and non burning smoke cooling.The results show that these two materials could not change the crystal structure of PL A.And SEBS could enhance the toughness,tensile property and impact strength of PLA better than PP.However,the degradation ability of blended materials decreases.SEBS+PLA composite material has better spinning performance and heating and non burning smoke cooling effect.
