▎ 摘　　要

NOVELTY - Temperature-resistant and anti-corrosion repairing agent comprises first filler, which is a spherical porous alumina, carbon nanotubes and zirconium oxide mixed in a mass ratio of 1-2:1: 1:1-2, second filler: a mixture of spherical silicon dioxide, graphene and spherical boron nitride, and average particle diameter of the second filler less than the average particle size of the first filler. USE - The repairing agent is used for wearable parts, corrosion-resistant repairing and pre-protective coating and repairing various defects e.g. crack, scuffing, size oversize, casting air hole, sand hole and sealing and plugging. ADVANTAGE - The repairing agent has high temperature resistance, corrosion resistance, green and environment-friendly.
