NOVELTY - Processing water heater exhaust assembly having self-cleaning effect involves contacting water glass, nano zinc oxide, nano copper oxide, graphene, sulfur and water, followed by hardening treatment, finally drying and crushing to obtain an antifouling auxiliary. The acrylic resin emulsion, white carbon black, a silane coupling agent, capsaicin, cobalt naphthenate, an organic solvent, and the antifouling auxiliary are mixed to prepare the self-cleaning coating. USE - Method for processing water heater exhaust assembly having self-cleaning effect. ADVANTAGE - The method enables to process water heater exhaust assembly which have effect of simmering oil, coating is stably adsorbed on the surface of the exhaust pipe of the metal water heater, water heater exhaust pipe is effectively achieve effect of simmering oil and self-cleaning.
