NOVELTY - Coating comprises raw materials comprising 30 pts. wt. macroporous resin, 10 pts. wt. silicon carbide, 5 pts. wt. non-crystalline quartz granule, 2 pts. wt. potassium feldspar, 5 pts. wt. tert-butanol, 10 pts. wt. graphene, 2 pts. wt. boron fiber, 2 pts. wt. carbon fiber, 2 pts. wt. potassium tungstate, 5 pts. wt. pigments, 50 pts. wt. deionized water, 2 pts. wt. lead tetraoxide, 3 pts. wt. rare earth metals, 3 pts. wt. chloromolybdic acid, 2 pts. wt. modified corn starch, 5 pts. wt. starch, and 0.5 pts. wt. cobalt. USE - The coating is useful for electrolytic capacitor shell (claimed). ADVANTAGE - The coating improves service life and heat radiation effect of the electrolytic capacitor shell. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the coating, comprising adding silicon carbide, non-crystalline quartz granule, potassium feldspar, lead tetraoxide, rare earth metals and ethanol to a dispersion medium in which the mass ratio of the dispersion medium and the ethanol is 1:20, performing ultrasonic dispersion of the added mixture for 1 hour, adding macroporous resin, graphene, boron fibers, carbon fibers, potassium tungstate and cobalt to the dispersed mixture, grinding the added mixture using a sand mil under stirring at a speed of 150 revolutions per minute for 4 hours, adding pigments and modified corn starch to the grinded mixture and then drying at 85-95 degrees C, pouring deionized water and tert-butanol to the dried mixture under heating to 50-60 degrees C for 30 minutes, filtering the poured mixture to obtain a filtrate, and drying the filtrate to obtain product.
