▎ 摘　　要

NOVELTY - Aerogel thermal insulation coating includes 40-60 wt.% aldehyde and ketone resin, 20-40 wt.% activated carbon, 10-15 wt.% nano silica, 5-10 wt.% aerogel and 2 wt.% dispersant. USE - Aerogel thermal insulation coating. ADVANTAGE - The aerogel thermal insulation coating has good thermal insulation and air purification effects, and is particularly suitable for thermal insulation and anticorrosion treatment of inner surfaces such as vehicles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an aerogel thermal insulation coating, which involves mixing the aldehyde and ketone resin, nano silica, aerogel, and dispersant, and dispersing uniformly at a speed of 800-1000 revolutions/minute, and then adding activated carbon, and dispersing for 10 minutes at a speed of 100-200 revolutions/minute to obtain aerogel thermal insulation coating.
