Abstract
This paper presents a novel intumescent flame retardant (IFR) material synthesized by utilizing a local resource and agricultural waste to meet the demand for sustainable IFRs, whereby Sago starch will act as a Carbon source in the IFR system while Rice Husk is added as a filler to enhance the flame retardancy of the Sago-based IFR. In this study, Borax is incorporated as an insect repellent, and to simultaneously reinforce the barrier effect of IFR. The thermal performance and cooling behavior of the IFR were assessed through a flammability test whereby one side of the IFR was subjected to intense flame for a duration of 15 minutes. The IFR with the optimal behavior will also be investigated.
This study successfully develops Sago-based IFR. Through the flammability test, both Borax and RH showed the potential to enhance the flame retardancy of IFR by improving its thermal insulation and thermal stability. However, through the investigation, it is found that the combination of Sago starch, Borax, and RH seems to have an antagonistic effect, whereas the combination of Borax and Sago starch exhibits a synergistic effect. The flammability test also determined that IFR consisting of 34g of Sago starch and 21g of Borax, without the addition of RH was found to exhibit optimal flame retardancy. From the analysis of IFR's cooling behavior, it is observed that IFRs with great thermal insulator ability were also found to have slower cooling rates than those with poor flame retardance properties. The outcomes of this study will contribute to developing sustainable, locally derived intumescent materials that could potentially be utilized for thermal insulation and fire prevention.
