EFFECTS OF DIFFERRENT BORON-BASED FLAME RETARDANTS ON THE COMBUSTIBILITY OF BAMBOO FILAMENTS

Abstract

In this study, eight types of boron-based flame retardants were performed to evaluate theeffects of different boron components on the combustibility of the bamboo filaments. Disodium octaborate tetrahydrate, boric acid/borax, and nano-ZnBO4were used as the active flame retardant components. Besides, other inorganic flame retardants including nano-SiO2and ammonium polyphosphate (APP) were also introduced in order to increase the flame retardant of these boron-based components. The combustibility of the bamboo filaments treated with different flame retardants were evaluated by cone calorimeter analysis. Theresults showed that the flame retardants including the heat release and smoke release resistance of the bamboo filaments with different boron-based components and nano-SiO2or APP, could be significantly improved, especially, in the samples treated with the compound flame retardant composed of boric acid, borax and nano-SiO2, which was attributed to the synergistic effect of these flame retardant components.
