Abstract

【Objective】 In this study, we attempted to investigate the smoke production and fire-retarding properties of fire-retardant bamboo scrimber, in order to reduce casualties and property loss during building fires. 【Method】The fire-retardant bamboo scrimber was prepared from the raw materials of bamboo bundles and fire-retardant compounds. The smoke-inhibiting properties, toxicity and smoke characteristics of fire-retardant bamboo scrimber upon burning were tested using a cone calorimeter. 【Results】 The fire-retardant bamboo scrimber was compared with the non-fire-retardant bamboo scrimber. The peak value of the total smoke release(TSR)was reduced by 30.5%, the peak value of the specific extinction area(SEA)was reduced by 40.5%, the peak value of the rate of the smoke release(RSR)was reduced by 27.8%, the peak value of the CO mass fraction was reduced by 74.7%, the average value of the CO yield was reduced by 68.8%, the peak value of the CO2 mass fraction was reduced by 21.4%, and the average value of the CO2 yield was reduced by 35.1%. 【Conclusion】 The smoke toxicity and smoke production of the fire-retardant bamboo scrimber were significantly lower than those of the non-fire-retardant bamboo scrimber. Therefore, the mixed fire retardant demonstrated remarkable smoke inhibition properties and toxicity attenuation.
