▎ 摘　　要

NOVELTY - Preparing graphene high-temperature resistant heat exchange enhancing coating comprises, dispersing powder layered mineral in organic polymer solution and uniformly mixing, performing spray drying to obtain layered mineral attached to organic polymer layer on the surface, subjecting the layered mineral attached to organic polymer layer on the surface to high-temperature heat treatment to obtain layered mineral/graphene composite, adding the layered mineral/graphene composite, silica sol, silane coupling agent and water into a stirring tank, stirring at the preset speed for the first preset time, and grinding for second preset time until the fineness scraper test coating is fine within the preset range. USE - The coating is useful in electronic component heat dissipation, heater heat efficiency, industrial heat exchange, and energy saving and consumption reduction of household appliances (claimed). ADVANTAGE - The coating: has strong adhesion and temperature resistance up to 800 degrees C; enhances the heat radiation effect on the surface of the object; and enhances the heat exchange effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene high-temperature resistant heat exchange enhancing coating prepared by above method; and (2) coating method of graphene high-temperature resistant heat exchange enhancing coating comprising coating the graphene high-temperature resistant heat exchange enhancing coating on the surface of the object by spraying, brushing or dipping, baking and curing at 80-300 degrees C for 10-60 minutes to form coating with heat radiation effect and enhancing heat exchange.
