▎ 摘 要
NOVELTY - The preparation method involves insulation mixing of materials. The insulation material is weighed according to the composition of the formula, and placed in the foaming machine and mixed in even manner. The conductive harness of the external power supply of the graphene heating chip is fixed. The heat insulation material is mixed uniformly. The heating insulation board is taken out after curing in the mold cavity. An appropriate amount of adhesive is sprayed on the bottom of ceramic tiles and graphene of heating insulation board. The electrical performance testing of graphene warm brick is generated. An electric heater is included for heating the appearance of bricks and detects electrical properties of graphene. USE - Preparation method for graphene heating electric heating brick. ADVANTAGE - The graphene heating electric heating brick prepared by the preparation method has good thermal insulation performance, good thermal efficiency, high structural stability and simple construction and maintenance. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of preparation method. (Drawing includes non-English language text).
