Current State and Development of Intumescent Fire Retardant Coatings for Steel Structure

A review was given on the current state and development of intumescent fire retardant coatings for steel structure.Thus the classification of the fire retardant coatings for steel structure was introduced, while the compositions and fireproofing mechanisms of the intumescent fire retardant coatings for steel structure were briefed.The thermal analytical technologies such as thermogravimetry,differential thermal analysis,and cone-type calorimeter analysis applicable to the characterization of the fire retardant coatings were highlighted.Moreover,the current state and development in the study and application of intumescent fire retardant coatings for steel structure was discussed.It was pointed out that though extensive investigations had been carried out with respect to the fire retardant coatings for steel structures,more efforts would be needed in future to dramatically decrease the thickness of the coatings and the pollution to environment during the coating production.Meanwhile,it was suggested to make more efforts so as to further improve the decoration effect and fireproofing behavior of the coatings,and to simplify the preparation processes as well.
