中文摘要:

      以自制多孔聚氨酯-聚丙烯酸/丙烯酰胺（PU-PAA/AM）智能恒湿材料为基础，设计了一种具有防震缓冲和恒湿性能的包装材料，根据其吸湿量与吸湿时间、平衡含湿量与相对湿度的关系，提出了通过控制预吸湿时间来实现存储包装内环境湿度恒定的方法和公式。将防震缓冲和恒湿性能有机结合起来，在武器装备贮运包装领域具有很大的应用价值。

英文摘要:

      A package material integrating humidity constant property and buffer function together was designed based on self-made spongy polyurethane-poly(acrylic acid-acrylamide) (PU-PAA/AM) humidity constant intelligent material. The method and formula to realize constant humidity in packaging internal environment through control of pre-absorption time was put forward according to the relation between moisture content and pre-adsorption time, and equilibrium moisture content and relative humidity. The packaging material integrates buffer function and humidity constant property together, so it is can be widely used in weapons storage packaging and transportation.
