Research on Thermal Response Behavior of the Intumescent Coating at High Temperature: An Experimental and Numerical Study

Intumescent coating is able to provide effective fire protection with both practicality and aesthetics. In this study, expansion performance thermal physical property experiments are firstly carried out obtain the basic parameters at different temperatures. Then, response model of concrete-filled steel tubular (CFST) structure under intumescent in a established. Finally, based on experimental data model, effects initial thickness, rate, intra-pore emissivity reaction heat temperature discussed detail. The results study can guidance formulation design, as well design.
