The mechanism of fire proofing of decorating intumescent fire-retardant coatings was firstly discussed,and the fire-resistant properties of decorating intumescent fire-retardant coatings were analyzed through the performance test on West PC60-3,then the differences between the decorating fire retardant coatings and other types of fire retardant coatings were contrastively analyzed in terms of fire proofing property,fire resistant time,feature,performance ratio,and influence of the environment where they were used.Finally,the development trends of the decorating fire retardant coatings were pointed out.
