摘　　要：以甘蔗渣碎料为主要原料,利用马铃薯淀粉作胶粘剂,采用模压成型法,以热压时间、热压温度、施胶量、甘蔗渣粒径为研究要素,结合正交实验制备甘蔗渣缓冲材料,并利用SPSS软件及微观形貌分析对其性能进行对比,以得出最优制备方案;进一步研究了甘蔗渣粒径及缓冲材料的密度对其性能的影响.结果表明,上述4个影响因素对缓冲材料各项力学性能影响的显著性有所不同;就材料的最小缓冲系数而言,当热压时间为50s,热压温度为120℃,施胶量为6%时,材料的综合性能最佳;材料的密度为170-190kg/m3 量级最为适宜;甘蔗渣粒径为8~14目时,缓冲材料最小缓冲系数达到最小值.In order to obtain the optimal preparation process,this research used bagasse as the main raw material and potato starch as adhesive.Then adopted the compression molding method to prepare cushioning material combining orthogonal experiment.Hot-pressing time,hot pressing temperature,glue consumption,bagasse particle size were studied as primary influence factors of preparation process.Used SPSS software and microstructure analysis to analyze the effect of these 4factors on the performance.Finally,this paper also do some research on the influence of bagasse particle size and the density of cushioning material on the performance further.The results showed that:these 4influence factors have significant difference on the mechanical properties of cushioning material.In terms of the minimum cushioning coefficient of bagasse cushioning material,the comprehensive performance of the material was the best when hot-pressing time was 50 s,hot-pressing temperature was 120 ℃ and glue consumption was 6%.The most appropriate density of cushioning material was the order of magnitude of 170-190kg/m3.When the mesh number of bagasse particle size is 8-14,minimum cushioning coefficient reaches the minimum.
