Bromine carbon alkyd resin was synthesized with soya oil acid, pentaerythritol, phthalic anhydride and brominated epoxy resin as materials under the condition which reaction temperature for 200 degrees C, usage of catalyst was 0.1% and period of esterification reaction lasted 3 h. And then bromine carbon alkyd resin retardant coatings for steel structure was prepared using bromine carbon alkyd resin as binder which compounded with flame retardant additives through stirred, grinded and dispersed homogeneously. Resin and coatings were analyzed by infrared spectroscopy and TG-DSC. The optimal formula of bromine carbon alkyd resin retardant coatings for steel structure was achieved through testing impact resistance, adhesive force, hardness, gloss, drying time and fire resistance time of film.
