Flexible reflecting material for increasing glazing rate of double-glass photovoltaic panel as well as preparation method and application of flexible reflecting material

The invention discloses a flexible reflecting material capable of increasing the glazing rate of a double-glass photovoltaic panel and a preparation method and application of the flexible reflecting material. The preparation method mainly comprises the steps of waterproofing, tentering and setting treatment, bottoming and coating of PVC paste resin slurry, overlay coating of the PVC paste resin slurry, gelling, drying and plasticizing treatment and three-time polyvinylidene fluoride intaglio printing surface treatment. And then knurling, cooling, shaping and the like are carried out. The flexible reflecting material provided by the invention has high reflectivity and good weather resistance, and does not cause temperature rise of a photovoltaic panel; meanwhile, the flexible reflecting material prepared by the invention is flexible on the whole, is easy to construct, install and maintain, and is suitable for photovoltaic installation and use requirements of various occasions. 本发明公开了一种增加双玻光伏板上光率的柔性反射材料及其制备方法和应
