The invention discloses an optical reflectivity surface treatment method. The optical reflectivity surface treatment method comprises the following steps that a product is placed on a product fixing frame, product surface oil contamination is removed through degreasing an water washing working procedures, and the product is cleaned; primary anodic oxidation treatment is carried out, and a sulfuricacid solution is adopted for carrying out primary anodic oxidation on the product; water washing is carried out after primary anodic oxidation, an alkaline solution is used for neutralization, and cleaning is carried out through water washing; sealed pretreatment is carried out, an activating agent is adopted for carrying out sealed pretreatment on the product; neutralization and water washing treatment is carried out after sealed pretreatment; secondary anodic oxidation treatment is carried out, and a sulfuric acid solution is adopted for carrying out secondary anodic oxidation on the product; water washing and neutralization are carried out after secondary anodic oxidation treatment, and water washing treatment is carried out; sealing treatment is carried out, and nickel fluoride and activating agent are adopted for carrying out sealing treatment on the product; and after sealing treatment, cleaning, drying and appearance detection are carried out, and the product is packaged. The product surface optical reflectivity is effectively reduced.
