摘要

目的旨在开发基于剪切增稠凝胶（STG）与聚氨酯（PU）复合发泡材料的高性能缓冲包装结构,以解决传统缓冲材料在高应变率冲击下能量吸收能力弱、易发生永久变形的问题。方法制备不同STG含量（0%、4%、8%、12%）的STG/PU复合泡棉,测试其密度、硬度及静动态压缩性能。将优化后的样品与传统EPE泡棉结合构建多层缓冲结构,通过落锤和落球冲击实验验证协同缓冲机制,并利用振动和跌落试验评估包装可靠性。结果 STG的引入显著优化了PU泡棉的静动态压缩性能,其中8% STG/PU样品在不同冲击高度下表现出最优的缓冲效果。多层结构提升了整体缓冲性能,验证了该材料在运输环境中的适用性。结论 STG提升了STG/PU复合材料的能量吸收效率和动态响应能力,8%添加比例下缓冲性能最优。多层结构增强了包装稳定性和可靠性。本研究为高性能缓冲包装材料开发提供了依据,拓展了非牛顿流体材料的应用路径。

Abstract

The work aims to develop a high-performance cushioning packaging structure based on shear-thickening gel (STG) and polyurethane (PU) composite foam materials, to address the issues of weak energy absorption capacity and susceptibility to permanent deformation in traditional cushioning materials under high strain rate impacts. STG/PU composite foams with different STG contents (0%, 4%, 8%, 12%) were prepared, and their density, hardness, and static/dynamic compression properties were tested. The optimized samples were combined with traditional EPE foam to construct a multi-layer cushioning structure. The synergistic cushioning mechanism was verified through drop hammer and drop ball impact tests, and packaging reliability was evaluated through vibration and drop tests. The experiments demonstrated that the introduction of STG significantly optimized the static and dynamic compression properties of PU foam, with the 8% STG/PU sample exhibiting the best cushioning effect under different impact heights. The multi-layer structure enhanced the overall cushioning performance, confirming the material's applicability in transportation environments. The results verify that STG significantly improves the energy absorption efficiency and dynamic response capability of STG/PU composites, with the 8% addition ratio providing optimal cushioning performance. The multi-layer structure enhances packaging stability and reliability. This research provides a basis for the development of high-performance cushioning packaging materials and expands the application pathways for non-Newtonian fluid materials.
