摘　　要：采用FRW阻燃剂对杉木积成材进行了阻燃处理,用锥形量热仪测定了不同载药率下处理材与未处理材的阻燃性能.结果表明:在50kW/m2的热辐射功率下,杉木积成材经FRW阻燃处理后,其热释放速率和总热释放量随着载药率的增大而减小,当载药率为10.07%(质量分数)时,处理材的热释放速率和总热释放量比未处理材降低了约50%;与未处理材相比,处理材的点燃时间明显延长,炭生成量明显增加;FRW阻燃处理杉木积成材的阻燃效果显著.Chinese fir oriented laminated stick lumber（Chinese fir OLSL） was treated using FRW fire retardant.The properties of fire retardant of treated and untreated Chinese fir OLSL were tested using cone calorimeter under different retentions.The results show that：at the heat radiation of 50 kW/m 2,heat release rate（HRR） and total heat release（THR） of the treated Chinese fir OLSL decrease with the increase of retention;at a retention 10.07%（by mass） the HRR and TH R of the treated Chinese fir OLSL are about 50% of the untreated;time to ignite（TTI） of treated Chinese fir OLSL is longer,and its char yield increase compared with the untreated;The overall effect of the FRW fire retardant treatment is remarkably significant.
