十二醇用量对植物纤维基泡沫材料结构的影响

Effect of content of dodecanol on structure of plant fiber based foam material

植物纤维基泡沫材料在取代泡沫塑料方面具有广阔的前景,研究泡沫体系的稳定性及泡沫材料的结构,对开发植物纤维基泡沫材料具有重要意义.本课题以植物纤维为原料,十二醇为泡沫稳定剂,制得植物纤维基泡沫材料,重点研究了十二醇用量对湿泡沫稳定性及泡沫材料结构的影响.结果表明,通过改变十二醇用量,可以实现对泡沫稳定性的调控,进而实现对植物纤维基泡沫材料结构的调控;当十二醇添加量为3.5%时,湿泡沫稳定性较好,泡沫材料的结构表现较优.

Plant fibers based foam material is very promising in replacing the foam plastic.It is of great significance to study the stability of the foam and the structure of the foam material for the development of plant fibers based foam material.In this study,plant fiber was used as the raw material and dodecanol was used as foam stabilizer to obtain plant fibers based foam material,and the effect of content of dodecanol on wet foam stability and foam structure was studied.The results show that the regulation of foam stability can be achieved by regulating the content of dodecanol,and then the regulation of structure of plant fibers based foam can be realized.The stability of wet foam was better and the structure of the foam material was superior when the content of dodecanol was 3.5%.
