目的 制备一种满足某弹药包装用防静电、耐老化的改性聚乙烯塑料。方法 首先，从弹药包装常用的聚乙烯塑料中优选一种耐老化性能较好的聚乙烯塑料，将其作为该弹药包装的主体材料。其次，借助塑料改性技术，开展聚乙烯塑料改性配方设计，对改性聚乙烯塑料的性能进行验证。最后，参照相关标准的试验方法，开展改性聚乙烯塑料的寿命评估。结果 研究的改性聚乙烯塑料内外表面的表面电阻率为0.1~10 GΩ∙m，贮存寿命约为11.43年。结论 研究的改性聚乙烯塑料满足某弹药包装用材料的使用要求。

The work aims to prepare a modified polyethylene plastic that can meet the requirements of anti-static and aging resistance for a certain ammunition packaging. Firstly, a polyethylene plastic with better aging resistance was selected from the commonly used polyethylene plastics for ammunition packaging as the main material of the ammunition packaging. Secondly, with the help of plastic modification technology, the polyethylene plastic modification formula design was developed, and the performance of modified polyethylene plastic was verified. Finally, according to the relevant standard test methods, the life evaluation of modified polyethylene plastics was carried out. The surface resistivity of the inner and outer surfaces of the modified polyethylene plastics studied was 0.1-10 GΩ∙m, and the storage life was about 11.43 years. The modified polyethylene plastic studied meets the requirements as a certain ammunition packaging material.
