The invention provides a multilayer flexible composite material functional film and a preparation method thereof, the multilayer flexible composite material functional film comprises a thin film layer 1 and a thin film layer 2, the thin film layer 1 comprises an outer thin film layer and an emission layer, the thin film layer 2 comprises a reflection layer and an inner thin film layer, and the outer thin film layer, the emission layer, the reflection layer and the inner thin film layer are sequentially stacked from top to bottom. The inner film layer and the outer film layer are made of any one or a composition of transparent polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF) or polyvinyl chloride (PVC), the emission layer is made of bead-shaped carbon black particles, the infrared emissivity of the outer surface of the functional film is improved, heat is prevented from being gathered on the outer surface, and therefore efficient heat dissipation of the outer surface of the functional film is achieved. The reflecting layer is made of sheet-shaped aluminum, efficient reflection of sunlight can be achieved through the reflecting layer, a large amount of heat is prevented from being absorbed on the outer surface of the multi-layer flexible material, and the rapid heat dissipation effect is achieved.
本发明提出一种多层柔性复合材料功能膜及其制备方法,包括薄膜层1和薄膜层2,薄膜层1包含外薄膜层和发射层,薄膜层2包含反射层和内薄膜层,其结构从上至下,依次层叠设置为依次层叠设置外薄膜层、发射层、反射层和内薄膜层。内、外薄膜层的材质为透明的聚氟乙烯PVF、聚偏二氟乙烯PVDF或聚氯乙烯PVC任意之一或其组合物,发射层的材质为珠状炭黑颗粒,提高功能膜外表面红外发射率,进而避免了热量在外表面聚集,从而实现功能膜外表面高效散热。反射层的材质为片状铝,反射层的作用可实现太阳光的高效反射,避免热量在多层柔性材料外表面大量吸收,达到快速散热的效果。
