▎ 摘　　要

NOVELTY - A coating comprises 55-65 pts. wt. film forming polymer, 15-20 pts. wt. attapulgite, 1-3 pts. wt. graphene foam, 1-3 pts. wt. metal organic framework, 2-5 pts. wt. hollow bismuth titanium oxide, 1-3 pts. wt. tetrakis(diethylamino)hafnium, 10-11 pts. wt. solvent, 2-6 pts. wt. defoamer, and 1-3 pts. wt. dispersant. USE - Coating used in wall. ADVANTAGE - The coating has high thermal insulation effect, and excellent comprehensive performance and large adhesion force to wall. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of thermal insulation coating, which involves adding film-forming polymer, graphene foam, metal organic framework and hollow bismuth-titanium-oxide to ball mill for ball-milling to obtain fine powder, putting fine powder and solvent into stirring tank, dispersing at speed of 1100-1300 rpm for 40-60 minutes, dripping attapulgite, defoamer and dispersant into stirring pot, dispersing at rotation speed of 1800-2000 rpm for 20-30 minutes, dripping tetrakis(diethylamino)hafnium to stirring tank, and dispersing at speed of 1500-1700 rpm for 10-15 minutes.
