▎ 摘　　要

NOVELTY - Building coating comprises 12-20 pt. wt. nano forsterite powder, 20-30 pt. wt. quicklime, 9-15 pt. wt. nano far-infrared titanium dioxide, 4-8 pt. wt. aerogel, 8-12 pt. wt. nano heat dissipation ceramic powder, 2-6 pt. wt. modified graphene oxide/carbon nanotube composite materials, 20-40 pt. wt. film-forming emulsion, 2-5 pt. wt. film-forming auxiliary and 2-6 pt. wt. auxiliary agent. USE - The building coating is used for indirectly reducing carbon emission, residential buildings, commercial buildings, office buildings, industrial buildings, and industrial buildings. Can also be used in aqueous architectural coating. ADVANTAGE - The building coating has excellent heat insulation, fast drying, fireproof performance and water resistance, anti-cracking performance and anti-artificial aging performance, and low carbon emission and stable mechanical property; does not organic solvent, formaldehyde-free, environment-friendly, and has good application prospect. The method is simple and easy to operate and suitable for popularization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing building coating for indirectly reducing carbon emission comprising (S1) preparing a modified graphene oxide/carbon nanotube composite material, (S2) providing the modified graphene oxide/carbon nanotube composite material, 1/2 dispersant and 1/2 film-forming emulsion into water, stirring and dispersing to obtain a modified graphene oxide/carbon nanotube composite material dispersion. (S3) adding quicklime, aerogel, nanometer far-infrared titanium dioxide, nanometer heat-dissipating ceramic powder, nanometer forsterite powder and 1/2 dispersant into water, and performing stirring treatment to obtain mixed slurry A, and (S4) adding the modified graphene oxide/carbon nanotube composite material dispersion liquid, 1/2 film-forming emulsion, film-forming aids and agent s to the mixed slurry A and stirring to obtain an architectural coating.
