中文摘要：

采用CONE法、热重-差示扫描量热法研究了改性海泡石与聚磷酸铵（APP）在木材燃烧过程中的阻燃作用和对烟雾毒气的调控作用。结果表明：改性海泡石和APP单独作用于木板时使木板的THR分别降低了27．55％，43．1l％；TSP分别降低了11．95％，54．56％，这说明APP和海泡石均具有阻燃和抑烟作用，APP比改性海泡石具有更好的阻燃及抑烟效果，但是APP单独作用的样品CO的平均产率增加了252．94％。改性海泡石和APP共同处理木材时，使木板的ATHR降低了44．75％，ATSP降低了84．42％，MeanCOY降低了81．86％。这说明APP和改性海泡石产生了协效阻燃和协效抑烟的作用，并且改性海泡石可以将APP作用下木材热解产生以CO为代表的大量有害气体充分催化氧化转换成了CO2气体，可以有效降低烟气毒性。改性海泡石与APP联用，在高效阻燃的同时减少烟雾毒气释放，降低火灾危害。

英文摘要：

Cone calorimeter method （CONE） and thermal gravity-differential scanning calorimeter analyzer （TG-DSC） were used to analyze the effects of modified sepiolite and ammonium polyphosphate （APP） on flame-retardation and smoke-suppression in the wood combustion process. The results show that the ATHR and ATSP of wood panels mixed with modified sepiolite decreased by 27.55% and 11.95%, respectively; The ATHR and ATSP of wood panels added APP reduced by 43.11% and 54.56%, respectively; It indicated that both APP and modified sepiolite had effects on flame-retardation and smoke-suppression of treated woods, and APP was better than modified sepiolite; However, the CO＇s mean yield of wood panels added APP increased by 252.94%; When the wood panels treated by modified sepiolite and APP, ArHR reduced 44.75%, ATSP reduced 84.42%, and mean carbon monoxide yield （YMCO） reduced by 81.86%; It indicated that APP and modified sepiolite had synergistic flame-retardation and smoke-suppression effects, and modified sepiolite can be fully converted the CO, which represents a large number of harmful gases produced in pyrolysis of woods, into CO2 by catalytic oxidation and thus effectively reduce smoke toxicity; Modified sepiolite combined with APP can lower noxious gas release and reduce fire hazard as well as effectively retard flame.
