研究用高粱秸秆和以聚乙烯醇、可溶性淀粉、水按一定质量比配制的粘接剂作为原料,经混合、交联反应、发泡等工艺过程,制备成一种发泡包装材料,并对该材料的微观结构进行研究。结果表明:所制得的新材料结构比较疏松,孔率可达21.254%,平均孔径有1.797 4×10-3~0.02 mm,而且其密度只有0.27 kg/cm3,该材料是一种极具开发前景的绿色缓冲包装材料。 In this paper, sorghum stalks and adhesives prepared with polyvinyl alcohol, soluble starch and water in a certain mass ratio were used as raw materials to prepare a kind of foam packaging material by mixing, cross-linking reaction and foaming process, The microstructure of the material was studied. The results show that the new material has a loose structure with a porosity of 21.254% and an average pore diameter of 1.797 4 × 10-3 ~ 0.02 mm with a density of only 0.27 kg / cm3. This material is a highly developed Green cushioning packaging material in foreground.
