▎ 摘  要

NOVELTY - High temperature resistant graphene anticorrosive coating comprises 20-50 pts. wt. oxide, 20-50 pts. wt. silicate, 1-10 pts. wt. additive, 0.5-5 pts. wt. graphene and 0-5 pts. wt. deionized water. USE - The coating is useful for electronics, electrical, aviation and petrochemical industries. ADVANTAGE - The method: is simple and convenient; improves the corrosion resistance and thermal conductivity of the coating; devices coated with this coating can dissipate heat quickly even when working in a highly corrosive environment; ensures that the device can work stably for a long time in a high temperature and high corrosive environment; mainly uses polymer materials; generally temperature below 200 degrees C; and the coating has withstand salt spray experiments for more than 96 hours, stable for a long time working in an environment of 500 degrees C, and thermal conductivity of 200W m(mK)-1. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing coating comprising (i) mixing oxide and graphene to obtain coating slurry mixed powder, (ii) mixing silicate and additive to obtain coating slurry mixed solvent, (iii) blending the mixed powder prepared in the step (i) and the mixed solvent prepared in the step (ii) to obtain coating slurry, (iv) adding deionized water into the coating slurry prepared in the step (iii), and evenly mixing, and (v) coating the coating slurry obtained in the step (iv) by spraying, dipping and brushing processes are applied to the surface of the treated substrate, curing the coated coating in air for 10-30 minutes, de-binding, and transferring to an oven at a temperature of 60-70 degrees C for curing to obtain final product.
