DETAILED DESCRIPTION - A thermally conductive ring comprises 10-12 pts. wt. silver powder, 18-20 pts. wt. aluminum nitride, 4-6 pts. wt. titanium nitride, 6-8 pts. wt. cubic boron nitride powder, 8-10 pts. wt. polycrystalline diamond powder, 3-5 pts. wt. silicon carbide, 6-8 pts. wt. chromium dioxide, 2-4 pts. wt. graphene, 25-27 pts. wt. liquid silica gel, 13-15 pts. wt. terpene resin, 30-32 pts. wt. oil-soluble phenolic resin, 19-21 pts. wt. cooked tung oil, 2-4 pts. wt. polyvinyl alcohol, 3-5 pts. wt. diphenylmethane bismaleimide, 4-6 pts. wt. fluorinated silicone rubber, 6-8 pts. wt. aminoethylpiperazine and 28-30 pts. wt. liquid bisphenol A type epoxy resin. The thermally conductive ring is prepared by (1) pouring cooked tung oil into a container, heating at 120 degrees C, adding oil-soluble phenolic resin, terpene resin, polyvinyl alcohol, diphenylmethane bismaleimide, and fluorinated silicone rubber, heating at 220 degrees C, and completely stirring until the material is completely dissolved to obtain viscous liquid, (2) pouring the liquid silica gel and graphene together into the container, uniformly stirring, adding silver powder, aluminum nitride, titanium nitride, cubic boron nitride powder, polycrystalline diamond powder, silicon carbide, liquid bisphenol A type epoxy resin, and chromium dioxide into a stirring pot, and uniformly stirring to obtain paste, (3) adding the prepared paste into the prepared viscous liquid, and uniformly stirring to obtain paste, (4) adding aminoethylpiperazine into the prepared paste, and uniformly stirring to obtain thick paste, and (5) placing the prepared thick paste into a mold, cooling, solidifying, and demolding.
