摘要
植物纤维基泡沫材料因其可完全降解及原料可持续再生等优势,在取代传统泡沫塑料方面极具前景,探索其微观结构与性能的关系,进而研究其结构与性能的调控技术,对于该新型发泡材料的开发具有重要的意义。本研究将植物纤维通过原纤化处理、发泡、注模、干燥成型等一系列工艺制得了植物纤维基泡沫材料,研究了表面活性剂十二烷基硫酸钠(SDS)用量对植物纤维基泡沫材料泡孔结构及静态压缩性能的影响。结果表明,通过调节SDS用量,可以实现对植物纤维基泡沫材料泡孔结构及静态压缩性能的有效调控;当SDS用量在0.02%~0.03%时,植物纤维基泡沫材料的泡孔分布均匀,此时获得的植物纤维基泡沫材料具有良好的力学性能。
Plant fiber based foam material has a great prospect in place of traditional polyfoam because of the foam can be completely degraded and the raw materials are sustainable renewable. It is of great significance to study the relationship between the foam microstructure and its performance for developing the new foam material. In this study, plant fibers based foam material was prepared through fibrillating of the fi- bers, foaming, injection molding and drying. Furthermore the relationships between the content of SDS and both of pore structure and static compression properties of the foam material were discussed. The results showed that the pore structure and static compression performance could be controlled by adjusting the content of SDS. The pores of the foam distributed evenly and the foam also had well mechanical properties when the content of SDS was in the range of 0. 02% -0.03%.
