▎ 摘　　要

NOVELTY - A high scratch resistance, wear-resistant coating material is prepared by taking 0.1-30 wt.% modified graphene, 20-89.9 wt.% polysiloxane resin (I), 0-50 wt.% mixed resin, 10-79.9 wt.% solvent, 0-30 wt.% curing agent, 0-50 wt.% pigment filler and 0-30.0 wt.% additive, and solidifying and forming at - 30 to 300 degrees C. USE - Method for preparing high scratch resistance, wear-resistant coating material used for surface protection and protection of metal, plastic, wood, concrete, glass and their mixed substrate (claimed). ADVANTAGE - The material has enhanced dispersability, improved mechanical, excellent adhesive force, and improved heat resistance, weather resistance, fire resistance, corrosion resistance. It is suitable for automobile paint, photoelectric material, precision instrument, anticorrosive heavy marine and construction fields.
