▎ 摘　　要

NOVELTY - Electrothermal coating comprises 5-20 pts. wt. organic polymer resin , 10-30 pts. wt. siloxane , silica sol 10-30 pts. wt., 1-10 pts. wt. graphene, 0.5-2 pts. wt. carbon nanotubes, 1-5 pts. wt. mica, and 1-5 pts. wt. wollastonite fibers and/or 1-5 pts. wt. alumina whiskers. USE - Electrothermal coating used for electrothermal heating, and in electric heating device (all claimed). ADVANTAGE - The electrothermal coating has high electrothermal efficiency, high temperature resistance and long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of preparing an electrothermal coating, which involves mixing the raw materials uniformly to obtain the electrothermal coating.
