摘要

本研究采用八种硼基阻燃剂来评价不同硼组分对竹纤维燃烧性能的影响。采用四水八硼酸二钠、硼酸/硼砂和纳米ZnBO4作为活性阻燃剂。此外，还引入了其他无机阻燃剂，包括纳米SiO2和聚磷酸铵（APP），以提高这些硼基成分的阻燃性。采用锥形量热计分析法对不同阻燃剂处理的竹纤维的燃烧性能进行了评价。结果表明，不同硼基组分的竹丝和纳米SiO2或APP的阻燃剂，包括热释放和防烟性，都可以显著提高，特别是在用硼酸、硼砂和纳米SiO2组成的复合阻燃剂处理的样品中，这归因于这些阻燃组分的协同作用。

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

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.
