摘要: 发泡聚丙烯(EPP)材料具有良好的压缩强度、力学性能、优异的回复性,并且可实现在家电产品包装上的循环利用。利用电子扫描显微镜、电子万能试验机、零跌落试验机、变频式模拟振动台和斜面冲击试验机对比了EPP和发泡聚苯乙烯(EPS)的微观泡孔形貌,拉伸强度、压缩强度、永久压缩强度并且验证了两种材料的循环使用可行性,结果表明,同等密度下EPP材料的拉伸强度均高于EPS,压缩强度与EPS材料接近,制件耐久性是EPS的5倍以上。经过试验验证了EPP材料产品包装具有优异防护效果,在家电包装行业的应用前景广泛。

Abstract: Expanded polypropylene (EPP) material has good compressive strength mechanical properties and excellent toughness, which could be recycled in the packaging of home appliances. The microscopic cell morphology, tensile strength, compressive strength of EPP and expanded polystyrene (EPS) were compared by scanning electron microscope, electronic universal testing machine, zero drop testing machine, frequency conversion simulation vibration table and inclined plane impact testing machine, permanent compressive strength, and cyclic use simulation test, the results show that the tensile strength of EPP material is better than EPS under the same density, the compressive strength is close to that of EPS material, and the durability of parts is more than 5 times that of EPS. The excellent protective effect of EPP material product packaging has been widely used in the home appliance packaging industry.
