填充型瓦楞纸板的力学性能研究

Mechanical Properties of the Corrugated Fiberboards Filled with Foam

为开发泡沫塑料回收新途径,同时提高瓦楞纸板的包装适应性,分别在A型瓦楞纸板中填充一定量聚乙烯(PE)和聚苯乙烯(PS)泡沫,获得填充型纸板A-PE和A-PS。并考查了泡沫填充对瓦楞纸板力学强度和缓冲特性的影响。实验结果表明:与未填充泡沫的A型瓦楞纸板相比,A-PE与A-PS的平压强度、边压强度、戳穿强度以及抗压性能都有较明显的提高,纸板的回弹性能也得到了改善。研究还发现:泡沫聚乙烯或聚苯乙烯的填充,有利于提高纸板的缓冲性能;但是填充聚苯乙烯泡沫对纸板的振动传递率影响不大,而填充聚乙烯将提高纸板的传递率,不利于防振包装设计。

Corrugated fiberboards were suggested to be filled with abandoned foams in order to improve their packaging adaptability, which may be also a new way of reuse for waste materials. Two filled A-type corrugated fiberboards were obtained through filling polyethylene foam or polystyrene foam （abbreviated as A-PE and A-PS）. Compared with the unfilled corrugated fiberboards, both of the filled ones＇ mechanical properties were enhanced efficiently including flat crush strength, edge crush strength and punctured strength. The rebound resilience of the corrugated fiberboards was also increased by filling polyethylene foam or polystyrene foam. At the same time, the results indicated the fillers can improve the cushion performance of the fiberboards. However, the addition of polystyrene foam had no obvious effects on the vibration transmissibility while the addition of polyethylene foams increased the vibration transmissibility but was not beneficiary to the design of anti-vibration package.
