The invention discloses an antibacterial flame-retardant ultraviolet-curable coating. The antibacterial flame-retardant ultraviolet-curable coating is prepared from the following raw materials in parts by weight: 33-36 parts of urethane acrylate, 19-22 parts of polyester acrylate, 12-14 parts of polyethylene glycol acrylate, 6-8 parts of glycidyl acrylate, 1-2 parts of turpentine, 4-5 parts of 2-methyl-2-hydroxy-1-phenylacetone, 5-8 parts of trimethylolpropane triacrylate, 4-7 parts of tripropylene glycol acrylate, 3-5 parts of butanone, 1-2 parts of polyacrylate, 4-6 parts of zinc oxide, 2-3 parts of talcum powder, 1-2 parts of IPBC (Iodo Propynyl Butyl Carbamate) and 4-5 parts of auxiliaries. Due to the added IPBC, the antibacterial flame-retardant ultraviolet-curable coating is safe and non-toxic, and has excellent antifungal and antioxidation effects; due to the added zinc oxide, the antibacterial flame-retardant ultraviolet-curable coating has closed effect in addition to flame retardant and antibacterial effects; furthermore, due to the added auxiliaries, the antibacterial flame-retardant ultraviolet-curable coating is good in leveling property, and an even coating coating can be formed, and the coating layer is high in curing speed, hard, wearproof, flexible and high in adhesion.
