一种具有防水透气性能的包装膜材料及其制备方法
摘要：
本发明公开了具有防水透气性能的包装膜材料及其制备方法，其以酚醛树脂、水溶性葡聚糖、聚乙烯醇、柠檬酸三丁酯为主要成分，通过加入己二酸丙二醇聚酯、凡士林、薏仁油、沸石粉、四硼酸钾、脱氢乙酸、氧化镧、聚乙烯蜡粉、甲基乙基酮肟、增塑剂、偶联剂，辅以恒温水浴、离心分离、真空干燥、研磨细化、微波处理、混炼、塑化、熔融挤出、热压成型等工艺，使得制备而成的具有防水透气性能的包装膜材料，其具有优异的防水透气性，且物理强度高，能够满足行业的要求，具有较好的应用前景。
摘要（英）：

The invention discloses a waterproof air-permeable packaging film material and a preparation method thereof. The waterproof air-permeable packaging film material is prepared by using a phenolic resin, water-soluble glucan, polyvinyl alcohol and tributyl citrate as the main components and adding polypropylene glycol adipate, vaseline, coix seed oil, zeolite powder, potassium tetraborate, dehydroacetic acid, lanthanum oxide, polyethylene wax powder, methyl ethyl ketone oxime, a plasticizer and a coupling agent. The preparation method comprises the following steps: thermostatic water bath treatment, centrifugal separation, vacuum drying, grinding refinement, microwave treatment, compounding, plasticizing, melt extrusion, hot pressing and the like. The waterproof air-permeable packaging film material has the advantages of excellent waterproofness, excellent air permeability and high physical strength, can satisfy the industrial requirements, and has favorable application prospects.
