摘要
以秸秆为原料,加入玉米淀粉、甘油、胶黏剂、填充剂和交联剂后烘焙发泡,制得复合发泡体。分析发泡体的密度、力学性能以及自降解性能,通过Design Expert Version 7.0.0软件对实验进行中心组合设计。结果显示：NaOH浓度、淀粉、胶黏剂和交联剂添加量对发泡体密度的交互影响显著;发泡体为黄褐色,表面光洁,气孔均密;单因素实验显示反应时间为10~14小时,反应温度为65~67℃;降解性能可能与淀粉添加量和周围环境有关。
Starch/Corn straw foam composites were fabricated by baking method from a mixture of corn straw and starch,abundant and natural renewable materials.The foam composites were characterized and analyzed with impact tester,and sensory evaluation.A central composite design was constructed using the software Design Expert Version 7.0.0 to evaluate the effects and interactions of four factors,i.e.NaOH content,starch content,adhesive and cross-link agent content on the treatment efficiency.The optimum conditions are： reaction temperature 65~67℃,reaction time 10~14h hour.
