摘　　要：为了满足木结构用材对阻燃与耐腐等性能的要求,采用硫酸镁、硼系处理剂与防水剂,复配制得复合处理剂(DBM),并将其用于处理南方松木材。检测结果表明,处理材达到强耐腐等级,抗流失性提高;处理材的有焰燃烧时间显著缩短,燃烧烟密度降低;处理材体积干缩率和吸水率降低;顺纹抗压强度略有增加,静曲强度和弹性模量变化不大。In order to develop wood products with acceptable fire resistance and decay resistance, Southern Pine samples were treated with a boroncontaining wood preservative （DBM） which was a mixture of disodium octoborate tetrahydrate, boric acid, magnesium sulfate and dipropylene glycol methyl etherResults indicated that the boronbased preservative not only improved the fire resistance, decay resistance, and reduced its leachibility, but also decreased the volume shrinkage and water absorption of treated samples.
