摘　　要：改性可发性聚苯乙烯(GPO)共混发泡材料是一种新型的缓冲包装材料。以GPO材料为研究对象,进行了静态压缩试验,利用MATLAB软件对实验数据进行了处理,获得了应力-应变曲线与缓冲系数-最大应力曲线,并基于最小缓冲系数和最大应力对某锂离子蓄电池产品进行了缓冲衬垫设计,对比几种缓冲材料的设计方案。研究结果表明,在230~320 kPa应力区间,GPO泡沫材料具有最优的缓冲性能,最小缓冲系数为2.6左右,GPO材料适合作为重型产品的缓冲包装。本研究对储运空间的合理利用和物流包装方案的改进具有重要意义。Grand polystyrene beads(GPO)blended foam is a new type of cushioning packaging material.Taking GPO as the research object,the static compression test was carried out.The experimental data were processed by MATLAB software,and the stress-strain curve and buffer coefficient maximum stress curve were obtained.Based on the minimum buffer coefficient and maximum stress,the buffer pad design of a lithium-ion battery product was carried out,while the design schemes of several buffer materials were compared.The results show that GPO foam material has the best cushioning performance in the stress range of 230~320 kPa,and the minimum cushioning coefficient is about 2.6.GPO material is suitable for the cushioning packaging of heavy products.The research is of great significance to the rational use of storage and transportation space,as well as the improvement in logistics packaging scheme.
