COMPOSITION OF HOT-MELT ADHESIVE FILM AND METHOD FOR PRODUCING SHOE SOLE

The present invention relates to a composition of a hot-melt adhesive film and a method for producing a shoe sole. The composition of the hot-melt adhesive film comprises a hot-melt adhesive material and an electromagnetic radiation absorbing material. The hot-melt adhesive material includes ethylene vinyl acetate and thermoplastic materials. The electromagnetic radiation absorbing material is uniformly dispersed in the hot-melt adhesive material. Energy of an electromagnetic radiation can be absorbed by the electromagnetic radiation absorbing material， thereby producing thermal energy， further increasing temperature and adhering property of the hot-melt adhesive film. Therefore， a midsole and an outsole of the shoe sole can be adhered by the hot-melt adhesive film. Further， the hot-melt adhesive film is made from recyclable materials. Therefore， the hot-melt adhesive film is fully recyclable.

本发明涉及一种热熔胶膜（Hot-melt Adhesive Film）组合物及鞋底制备方法。该热熔胶膜组合物包含热熔胶基材与电磁辐射吸收材料（Electromagnetic Radiation Absorbing Material）。所述热熔胶基材包含乙烯-醋酸乙烯酯共聚物（Ethylene Vinyl Acetate）及热塑性材料。所述电磁辐射吸收材料均匀分散于该热熔胶基材中。电磁辐射吸收材料可吸收电磁辐射能量并转化为热能，进而提升该热熔胶膜的温度与粘结性能，借此实现鞋底中底与外底的粘结固定。此外，该热熔胶膜采用可回收材料制备而成，因此具备完全可回收的特性。
