NOVELTY - Black coating is formed by curing black rubber material, where the black rubber material comprises a component of 1-15 pts. wt. black pigment, 10-54 pts. wt. filler, 1-5 pts. wt. agent, 10-60 pts. wt. conductive powder, 10-60 pts. wt. radiating powder, and 2-6 pts. wt. auxiliary agent. USE - Black coating (claimed). ADVANTAGE - The black coating has provided the production cost is low, the preparation method is simple and easy to operate, stability has improved, has improved the beauty of the product, has ensured the adhesive force after drying the black coating is good the repeated folding is not easy to fall off good flexibility when spot welding is not easy to be damaged and at the same time, it has good reflecting performance uniform thickness smooth surface and can increase the conductivity of the welding belt. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing black coating, which involves: a. taking the corresponding weight fraction of black pigment, coupling agent conductive powder, and radiating powder, and adding it to the high-speed dispersion machine, uniformly dispersing to obtain the mixed raw material, b. adding filler and auxiliary agent into the mixed raw material obtained, dispersing and processing again to obtain black rubber material, c. standing the black rubber material obtained at 120 degrees centigrade for 10 minutes then raise the temperature to 270 degrees centigrade, standing for 1 minute, then dispersing again after dispersing vacuum degassing to obtain the black coating.
