The invention discloses a heat-insulating self-cleaning architectural
coating, which is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of a
bisphenol epoxy resin, 20-30 parts of a
nano silicon resin, 3-4 parts of 2,2,4-Trimethyl-1,3-pentanediol monoisobutyrate, 0.5-1.0 part of
aluminium oxide, 1-2 parts of glyceryl tristearate, 3-5 parts of
polytetrafluoroethylene powder, 1-2 parts of shell-lac, 2-3 parts of
polyethylene wax, 3-4 parts of
fly ash floating beads, 0.3-0.4 part of azodiisobutyronitrile, 0.2-0.4 part of polyether modified
siloxane, 1-2 parts of
zinc naphthenate, 1-3 parts of polymerized silica, 6-9 parts of self-cleaning
slurry, 1-2 parts of aminopropyltriethoxysilane, 10-13 parts of
ethyl acetate, and 5-7 parts of
ethylene glycol. The
coating disclosed by the invention is used for solving the problem that a coat is poor in
fouling resistance, easily polluted, and not ideal enough in heat insulation effect. The added
fly ash floating beads are good in heat insulation effect and low in cost, and the added self-cleaning
slurry has a good self-cleaning effect; the
coating disclosed by the invention is high in adhesion and good in abrasion resistance, and has excellent heat insulation and self-cleaning functions; and the coating is low in production cost, simple in operation and wide in application range.
