Formulation of intumescent flame retardant coatings containing naturalbased tea saponin
Natural product tea saponin (TS), extracted from the nutshell of camellia (Camellia oleifera Abel, Theaceae), was introduced into intumescent flame retardant formulations as blowing agent and carbon source.The formulations of flame retardant system were optimized to get the optimum proportion of TS, and intumescent flame retardant coatings containing tea saponin (TS-IFRCs) were then prepared.It was found that TS can significantly affect the combustion behaviour and the thermal stability of TS-IFRCs evaluated by cone calorimetry and simultaneous thermal analyzer, respectively.It was shown that TS, degraded to water vapor and carbon at high temperatures, can combine with other components to form a well-developed char layer.And the char layer was supposed to inhibit the erosion upon heat and oxygen, and enhance the flame retardancy of TS-IFRCs.
