一种反射型的辐射制冷薄膜
摘要：
本发明公开了一种反射型的辐射制冷薄膜，包括依次设置的涂布层、金属层、透明聚酯PET层、装贴胶和离型保护膜，所述涂布层包括有机类丙烯酸涂料和微米球体，所述微米球体为SiC、SiO2、TiO2、BaSO4、CaCO3中的一种；所述金属层通过磁控溅射方法沉积到透明聚酯PET层上；其中，各层的厚度与所述辐射制冷薄膜总厚度的占比如下：涂布层：2％～10％，金属层：0.01％～0.1％，透明聚酯PET：14.9％～87.99％，装贴胶：5％～40％，离型保护膜：5％～35％。本发明通过将粒径在1～15μm左右的微米球体随机地镶嵌在聚甲基丙烯酸甲酯涂料中制成50～150μm厚的薄膜。本发明的薄膜制备方法简单易行、成本低廉且辐射制冷效果较好。
摘要（英）：

The invention discloses a reflective radiation refrigeration film which comprises a coating layer, a metal layer, a transparent PET (polyethylene terephthalate) layer, adhesives and a release protective film which are sequentially arranged. The coating layer comprises organic acrylic coatings and micro-spheres, the micro-spheres are one of SiC, SiO2, TiO2, BaSO4 and CaCO3, the metal layer is deposited on the transparent PET layer by a magnetron sputtering method, and the ratios of the thicknesses of all the layers to the total thickness of the radiation refrigeration film include 2%-10% of thecoating layer, 0.01%-0.1% of the metal layer, 14.9%-87.99% of transparent PET, 5%-40% of the adhesives and 5%-35% of the release protective film. The micro-spheres with the particle size of 1-15 micrometers are randomly inlaid into polymethyl methacrylate coatings to prepare the film with the thickness of 50-150 micrometers. The film is simple and easy in preparation method, low in cost and goodin radiation refrigeration effect.
