The heat release and smoke release of two kind of biomass-based tea saponin flame retardant coatings prepared with different methods, was studied by using cone calorimeter（CONE）, in order to evaluated and analyzed its flame retardancy and smoke suppression performance. The results show that reactive type tea saponin intumescent flame retardant coatings have superior performance, and less smoke release, which effectively reduce the degree of fire hazard, but due to the formation of carbon layer enables the expansion of incomplete combustion, C...
