| 摘要:根据我军武器装备储存和防潮封套技术发展现状，对封套材料提出了新的使用要求和性能设计指标，重点研究了如何提高材料阻隔性和综合防护性能。针对提出的性能要求，选择了综合性能优异的PVDC材料为封套的阻隔层，并首次采用共挤吹塑和干法复合加工工艺，将PVDC与TPU材料进行了复合，加工制得了具有阻隔性高、阻燃性好和质量轻等特点的PVDC复合封套材料。 |

| Abstract:New application requirements and performance index of envelop material were put forward according to the development status of our materiel storage and moistureproof envelop technology. The ways to improve barrier performance and integrated protection performance were studied. According to performance requirement, PVDC was selected as barrier layer of envelop for its excellent overall performance. Coextrusion blow molding and dry composite processing technology was first applied to make composite of PVDC and TPU. PVDC composite envelop material was manufactured, which has high barrier performance, good flame retardance, and light weight. |
