以魔芋胶为原料，选择无毒性的交联剂、发泡剂等试剂来制备魔芋纤维发泡海绵.通过反复多次试验，制备出内部空隙直径约2~3 mm、吸水率范围约在6%~19%之间的魔芋纤维发泡海绵，并探究了在不同发泡剂与交联剂用量下魔芋纤维发泡海绵的性能，研究了制作工艺对产品性能的影响.以魔芋胶80~100 g、发泡剂2~4 g、交联剂4 g、增韧剂2 g、浸润剂4 g、增塑剂10 g加入1 L水中搅拌均匀后升温至100~110℃，保温1.5 h所制得的魔芋纤维发泡海绵具有良好的强度、吸水性能和生物降解性.%Such reagents as non-toxic cross-linking agent and foaming agent were taken to produce konjac-fiber-based foam sponge with konjac gum as raw materials. Konjac-fiber-based foam sponge with 2-3 mm internal void diameter and 6% 19% water absorption was prepared after a number of experiments. The paper made research of properties of konjac-fiber-based foam sponge resulting from different dosage of foaming agent and cross-linking agent,and studied production process influence on the product properties. With 80 100 g konjac gum,2 4 g foaming agent,4 g cross-linking agent,2 g toughening agent,4 g wetting agent and 10 g plasticizer mixed in 1 L water and stirring,heating up to 100 110 ℃and holding 1.5 h,the obtained konjac-fiber-based foam sponge had good performance of strength,water absorption and biodegradability.
