摘　　要：木材保护药剂SBB处理马尾松材后对木材湿胀性、力学性能及阻燃性能影响的研究结果表明:处理材的气干湿胀率与未处理材相比有所增大,(NH4)2HPO4与SBB质量配比对试材湿胀率的影响不明显。质量比为1∶3的(NH4)2HPO4与SBB的混合液以10%浓度处理的试材的体积湿胀率为最小,且该混合液处理的试材阻燃性能最佳。随着药剂处理浓度的增大,处理材顺纹抗压强度增大较明显,处理材静曲强度和抗弯弹性模量略有降低。The swelling property,strength and fire resistance of masson pine treated by SBB preservative were tested,the result show that: the air-dry maximum swelling of treated timber was higher comparing with that of untreated timber,the effect of ratio between(NH4)2HPO4 and SBB on the air-dry maximum swelling was not obvious.The volume swelling of treated timber was lowest when the timber was treated with 10% solution of preservative with the ratio(NH4)2HPO4 ∶SBB= 1∶3,and the fire resistance was best at this condi...
