摘要
以纸质纤维为主料制得的植物纤维基发泡制品,是近年来出现的一种新型缓冲材料。设计了3个单因素试验,以废纸纤维和淀粉类胶黏剂为主要原料,将2种不同种类的发泡剂以3种组合方式施加到混合物中,采用微波发泡的方法制备了纸纤维发泡材料。通过测定样品成型后的密度、发泡倍率、发泡失重率和干燥失重率,比较了3种不同的发泡剂配方对样品性能及制备过程的影响程度。结果表明:利用各种发泡剂分解温度相异的特点将发泡剂复配,使纸纤维材料在加热过程中分段发泡,具有较好的发泡效果,而且后期干燥的能耗也少。
Foam material prepared mainly by waste paper fiber is a new cushion material in recent year.Three single-factor tests were designed.Waste paper fiber and starch were used as main materials;two kinds of foaming agent were applied to the material with three kinds of combination;and microwave radiation method was used to prepare paper fiber foam materials.The density,foaming rate,foaming weight loss rate,and dry weight loss rate of the molded samples were tested and the influence of different foaming agent formula on sample properties and fabrication process was compared.The results showed that composite foaming agent has better foaming effect and less energy consumption than single foaming agent.
