摘　　要：采用自制搅拌球磨机对甘蔗渣进行机械活化预处理,以碳酸氢钠、碳酸氢铵、碳酸铵的混合配方为发泡剂,滑石粉为填料,木薯淀粉为粘合剂制备蔗渣纤维缓冲包装材料。通过单因素实验设计,得到较优的反应条件为:机械活化2.0h,温度120℃,粘合剂质量分数20%,发泡剂质量分数10%,填料质量分数20%。在该条件下制备的蔗渣纤维缓冲包装材料密度为0.228g·cm-3,压缩强度为1.751MPa。结果表明:机械活化有效增强甘蔗渣与淀粉及填料等物质的界面相容性,有利于立体网状结构的形成,有效提高了蔗渣纤维缓冲包装材料的缓冲性能。The bagasse fiber-based cushion packaging material（BFCPM）was prepared by using mechanically activa ted bagasse as raw material, compound of sodium bicarbonate, ammonium bicarbonate and ammonium bicarbonate as foa ming agent, talcum powder as filler, and cassava starch as adhesive. Through the single factor experiment design, the opti mum reaction conditions were determined as mechanical activation time（tM）2. Oh, reaction temperature 120℃, adhesive con- tent 20 %, foaming agent content 10 % and filler content 20 %. Under these conditions, the density and compressive strength of BFCPM were 0. 228g .cm-3 and 1. 751MPa, respectively. The results showed that mechanical activation efficiently im proved the compatibility among bagasse, starch and filler, contributing to the formation of a stereo meshwork structure, which could obviously enhance the cushioning properties of BFCPM.
