▎ 摘　　要

NOVELTY - The plastic pipe (1) comprises a high thermal conductivity material (100), in which the graphene in the form of a powder is contained in the inside. A thermal conduction coating layer (200) is formed on the surface of the pipe in which the graphene solution is contained. The high thermal conductivity material is arranged on a graphene element (110) containing 40 to 50 wt.% of graphene powder. The graphene solution is heated up with the sulfuric acid to 90 degree Celsius and 10 grams of potassium persulfate and 10 grams of phosphorus pentoxide are mixed and stirred. USE - Plastic pipe for heat conductivity containing graphene. ADVANTAGE - Rapid thermal conductance is obtained from the process of heat emission to the outside of the pipe through the high thermal conductivity material. DETAILED DESCRIPTION - The extracted graphene is put with 460 milliliter of sulfuric acid into the beaker and passed through preprocessing in the beaker, in which 60 grams of potassium permanganate is put and completely melted. 20 to 30 wt.% of the hydrogen peroxide is mixed in a solution, in which the hydrochloride and distilled water are mixed at certain ratio. A binder is provided, which is a mixture of alkoxide or silica and the flux powder made of potassium, aluminum and fluoride group, potassium, zinc and fluoride group or potassium, silicon and fluoride group material, and a solvent made of propanol, ethylene glycol or ethyl ether. An INDEPENDENT CLAIM is included for a manufacturing method for a plastic pipe. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a plastic pipe.
