The invention relates to a persistent aromatic wall coating, which is prepared from the following raw materials by weight part: 60-70 of trimethylolpropane triacrylate, 15-20 of an aromatic amine curing agent , 10-15 of E-42 epoxy resin, 3-5 of guar gum, 3-5 of calcium alginate, 0.4-0.7 of linalool, 7-10 of zinc oxide, 0.3-0.45 of phenethyl alcohol, 1-2 of polylactic acid microspheres, 13-16 of ethyl acetate, 2-3 of silicon carbide micropowder, 5-7 of polyisocyanate, 5-6 aluminum powder, 5-7 of tributoxyethyl phosphate, and 4-6 of an adhesion assistant. The coating provided by the invention adopts phenethyl alcohol, linalool and polylactic acid microspheres able to persistently emit fragrance to cover the intrinsic odor of the coating. By adding the silicon carbide micropowder, the abrasion resistance and heat-conducting property of a coating film are improved. By adding zinc oxide, the coating can achieve sterilizing and mould-proof effects, has increased aesthetic feeling, and good flame resistance, thus having a wide range of application.
