▎ 摘　　要

NOVELTY - A coating sealing material comprises 40-45 pts. wt. silicone resin dispersion, 10-15 pts. wt. phenolic resin dispersion, 5-10 pts. wt. ceramic powder, 10-15 pts. wt. additives, and 1-5 pts. wt. nanocomposite which is iron oxide-graphene nanocomposite. USE - Coating sealing material. ADVANTAGE - The coating sealing material has excellent wear resistance, corrosion resistance, high temperature resistance and adhesion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of coating sealing material, which involves mixing organic silicone resin dispersion and phenolic resin dispersion evenly, stirring, mixing mixture, iron oxide-graphene nanocomposite, ceramic powder and additives, dispersing for 1 hour at high speed in emulsifying and homogenizing machine to obtain colloidal sealing material, leaving still for 24 hours, and drying in oven.
