摘要

目的获得PE基封套薄膜材料的结构差异对其阻隔性能变化规律,为设备防护时选取薄膜材料提供理论和数据支撑,以提升设备防护体系的环境适应性与材料选型的适用性。方法选用聚乙烯膜、铜粒子改性膜、铝塑膜和聚酯塑料膜为试验样品,通过系统评估材料的撕裂强度性能、吸水性能、水蒸气传输性能（WVTR）及静水阻力性能,探究多层复合结构、金属粒子掺杂等要素对阻隔性能的作用机制。结果通过对四种封套薄膜材料进行关键性能测试,得到试验样品的各项性能具体参数。结论铜粒子改性膜具有优异的抗太阳辐射能力、撕裂强度、防水能力及基本的抗静水压能力,其独特的铜粒子分布结构使其十分适用于户外、敞开式或半封闭式环境的设备长期稳定防护,对提升设备防护体系的环境适应性与材料服役寿命具有重要工程应用价值。

Abstract

The work aims to investigate how structural differences in PE-based envelope film materials affect the variation patterns of their barrier properties and provide effective theoretical and data support for selecting appropriate film materials in equipment protection scenarios, so as to improve the environmental worthiness of equipment protection systems and the suitability of material selection.. With polyethylene films, copper-ion modified films, aluminum-plastic composite films, and polyester plastic films as test specimens, the action mechanisms of factors such as multilayer composite structures and metal particle doping on barrier properties were analyzed by evaluating key parameters including tear strength performance, water absorption capacity, water vapor transmission rate (WVTR), and hydrostatic resistance performance. Key property tests were carried out on four types of envelope film materials to obtain specific property parameters of test samples. Notably, the copper-ion modified film demonstrates exceptional solar radiation resistance, superior tear strength, effective water barrier capabilities, and basic hydrostatic pressure resistance. Their unique copper particle distribution structure renders them highly suitable for long-term stable protection of equipment deployed in outdoor, open or semi-enclosed environments, and possesses important engineering application value for improving the environmental worthiness of equipment protection systems and the service life of materials.
