High-barrier hot melt adhesive film, preparation method thereof and composite board
The invention relates to a high-barrier hot melt adhesive film, a preparation method thereof and a composite board. The hot melt adhesive film comprises a first adhesive layer used for being bonded with PVC, a second adhesive layer used for being bonded with metal and a transition layer arranged between the first adhesive layer and the second adhesive layer. The raw materials of the first adhesive layer comprise copolyester and styrene-acrylonitrile-glycidyl methacrylate, and the raw materials of the transition layer comprise nylon, maleic anhydride grafted polyethylene and glass flakes. According to the hot melt adhesive film disclosed by the invention, the raw material formula of the first adhesive layer and the transition layer is redesigned, so that the hot melt adhesive film has better plasticizer barrier property, better high-temperature peel strength and harder peel strength retention rate after thermal aging, and the hot melt adhesive film is used for bonding a composite board obtained by metal and PVC (Polyvinyl Chloride), so that the service life of the composite board is prolonged. The adhesive can be used in a more stringent use environment, and is especially suitable for the peeling strength requirement under long-term use conditions with high outdoor temperature throughout the year, such as areas near the equator.
本发明涉及一种高阻隔的热熔胶膜及其制备方法和复合板，热熔胶膜包括用于与PVC粘接的第一胶层、用于与金属粘接的第二胶层及设置在第一胶层和第二胶层之间的过渡层，第一胶层的原料包括共聚酯和苯乙烯‑丙烯腈‑甲基丙烯酸缩水甘油酯，过渡层的原料包括尼龙、马来酸酐接枝聚乙烯和玻璃鳞片。本发明的热熔胶膜通过重新设计第一胶层和过渡层的原料配方，使得该热熔胶膜具有更好的增塑剂阻隔性能，具有较好的高温剥离强度和更严苛的热老化后的剥离强度保持率，将该热熔胶膜用于粘接金属和PVC获得的复合板，能够用于更加严苛的使用环境中，特别适用于赤道附近地区等户外温度常年较高的长期使用条件下的剥离强度的要求。
