▎ 摘 要
NOVELTY - The material has a set of coated roofing granules (100) provided with a roofing granule (102) with an outer surface. A granule coating (104) is located on a portion of an outer surface of the roofing granule. The granule coating is formed with an outer surface. A set of graphene particles is disposed on a portion of the outer surface of the granule coating. The set of grapheme particles covers 50% of the outer surface of the granule coating. The set of grapheme particles is directly exposed to an environment. The granule coating comprises one of a metal silicate binder, a phosphate binder, a fluoropolymer coating, an acrylic coating, a polyurethane coating, a sol-gel coating and a silica coating. USE - Graphene roofing material i.e. dark colored roofing shingle (claimed). ADVANTAGE - The graphene is applied to the material to improve surface property of the material, reduce solar heat absorption of the material, increase total solar reflectance of the material, improve aesthetics of the material by imparting or retaining dark appearance of the material, reduce algae growth without use of heavy metal biocides on the material, reduce leaching of iron ions for reducing rusting potential of the material, improve color lightfastness for organic pigments or dyes and impart UV opacity to the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a roofing material. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a portion of a coated roofing granule. 100Coated roofing granules 102Roofing granule 104Granule coating
