NOVELTY - A superconductive flat solar energy heat absorbing plate manufacturing method involves welding aluminum, copper or steel plate (1) on a superconducting heat transfer tube (4). Composite oxide of copper, chromium, iron and manganese and a binder comprising polyethylene, polypropylene or silicone are mixed, and organic solvent is added to the obtained mixture to obtain black liquid. A surface of the plate is subjected to degreasing followed by drying and spraying an adhesive coating (7). The obtained black liquid is sprayed on the plate followed by naturally drying plate.    USE - Method for manufacturing a superconductive flat solar energy heat absorbing plate.    ADVANTAGE - The method enables manufacturing superconductive flat solar energy heat absorbing plate in an economical manner. The plate is reliable and convenient to use, and has high absorption ratio and low comprehensive reflection ratio.    DETAILED DESCRIPTION - A superconductive flat solar energy heat absorbing plate manufacturing method involves welding aluminum, copper or steel plate on a superconducting heat transfer tube by using a laser welding or ultrasonic welding equipment. Composite oxide of copper, chromium, iron and manganese and a binder comprising polyethylene, polypropylene or silicone are mixed at a ratio of 1: 4, and organic solvent is added to the obtained mixture to obtain black liquid. A surface of the plate is subjected to degreasing followed by drying and spraying a layer of adhesive coating. The obtained black liquid is sprayed on the plate using an automatic spray gun under pressure of 0.3-0.5Mpa and under presence of compressed nitrogen gas. The plate is dried naturally at room temperature to form a solid optical coating (2), where thickness of the coating is uniformly adjusted to 0.05-0.07 mm.
