▎ 摘  要

NOVELTY - The utility model claims a solar heat collecting tube is coated with super-hydrophobic-graphene composite coating, super-hydrophobic-graphene composite coating solidified by ultraviolet light formed by graphene oxide and light catalytic active nanometer particle titanium dioxide composite coating. the solar heat collecting tube comprises a glass outer tube and metal inner tube, sleeved in the sealed cavity is formed between the two, the inner and outer wall of the glass tube are coated with the antireflection coating, out of each antireflective coating wearable graphene coated with the super-hydrophobic composite coating, the graphene and titanium dioxide of physical and chemical properties such as hydrophobic and transparent, so that the coating of the solar heat collecting pipe which is featured with abrasion resistance, strong weather resistance, strong light transmittance, it has good self-cleaning ability, and can effectively resist sand erosion of the heat collecting tube, it applies to illumination resource rich desert region.
