可生物降解高吸水材料的制备以及制备工艺对吸水倍率的影响

Preparation of Biodegradable High Water Absorbent Material and Effect of Preparation Processes on Water Absorbency of the Material

以淀粉为原料 ,采用反相悬浮聚合方法 ,通过研究交联反应时反应时间、搅拌速度、反应温度以及催化剂质量分数、交联剂质量分数、淀粉质量分数和分散剂质量分数一系列工艺条件制备出可完全生物降解的高吸水材料 ,通过测定高吸水材料的吸水倍率揭示出制备工艺对可生物降解高吸水材料吸水倍率的影响规律。

With starch as raw material, fully biodegradable high water absorbent material was prepared by means of inverse suspension polymerization under a series of process condition, including reaction time, stirring speed, reaction temperature and concentration of catalyst, crosslinking agent, starch and dispersant. The effect of preparation processes on water absorbency was revealed.
