NOVELTY - Heating sizing agent comprises graphene, MAX phase ceramic material, film-forming resin and solvent. USE - The heating sizing agent is useful for heating micro-crystal plate (claimed). ADVANTAGE - The heating sizing agent: has good heating performance, high electric-heat radiation conversion; and is good for controlling heating coating of heating preparation of the resistor and conductivity. The method: is simple, and fast; has high efficiency, and formed heating coating has strong adhesion effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing heating sizing agent comprising dispersing graphene and film-forming resin in a solvent, mixing and then adding MAX phase ceramic material to obtain heating sizing agent; (2) a heat-generating coating; and (3) a heating micro-crystal plate comprising heating sizing agent and microcrystalline plate base material.
