Influence of polymer binders,fillers and fire retardant agents on the fire retardant properties of fire retardation coating and corrosion retardantion was studied by means of the orthogonal experiment method.The results show that the fire retardant agent was the key factor.Farther more the influence of foam agent,carbonizing agent and dehydration catalyzer was discussed.It is proved that the anticorrosion property enhences with the decrease of the particle size and solubility in water of the fire retardant agent.
