▎ 摘  要

NOVELTY - Protecting object or ornamental surface of rocky origin involves synthesizing graphene oxide chemically in an acid medium, dispersing the graphene oxide paste obtained in water, neutralizing the graphene oxide dispersion obtained up to a pH between 4.5-5.5 of dialysis in water, eliminating the water contained in the graphene oxide, preparing a colloidal dispersion of graphene oxide in a concentration between 0.1-1 mg/ml from the graphene oxide obtained and water, spraying the dispersion obtained exclusively on an object or an ornamental surface of rocky origin and keeping the percentage of obscuration at values less than 1. USE - Method for protecting object or ornamental surface of rocky origin. ADVANTAGE - The method enables to protect object or ornamental surface of rocky origin eliminates the water contained in the graphene oxide.
