摘　　要：选用自配阻燃剂和FRW阻燃剂处理杨木单板,探讨不同种类阻燃剂、浸渍时间、浸渍浓度、热压温度对胶合板载药量、胶合强度以及阻燃性能的影响。结果表明：选用自配阻燃剂时,载药量1.4322%～13.4726%,氧指数36.6%～89.9%,胶合强度0.131～0.798 MPa;选用FRW阻燃剂时,杨木阻燃胶合板的载药量1.5449%～14.7724%,氧指数45.3%～70.5%,胶合强度0.233～0.698 MPa。经过自配和FRW阻燃剂处理后,杨木胶合板的阻燃性能均得到明显改善,其中氧指数远大于日本JISD1322-77中的难燃一级品的要求,但是其胶合性能显著下降。This paper studied the poplar veneer, and impregnated them with self-made fire retardant and FRW fire retardant, to discuss the influence of different fire retardant, impregnation time, impregnation concentration, hot-pressing temperature on the fire retardant retention quantity, the bonding strength and the fire-retardant properties. The results showed that fire retardant retention quantity, oxygen index and bonding strength were 1.4322%-13.4726%, 36.6%-89.9% and 0.131-0.798 MPa with self-made fire retardant treatment while the fire retardant retention quantity, oxygen index and bonding strength were 1.5449%-14.7724%, 45.3%-70.5% and 0.233-0.698 MPa with FRW fire retardant treatment. Through the self-made and FRW fire retardant treatments, the fire retardant properties of poplar plywood were significantly improved,the oxygen index had reached and was much higher than the flame retardant grade request in JISD1322-77,but its bonding strength significantly decreased.
