摘　　要：以树脂型阻燃剂与低分子酚醛树脂复配作为药剂对大青杨进行改性处理,提高木材的阻燃性。研究表明,当阻燃剂浓度为10%时,其氧指数为51%;当浓度为25%时,氧指数可达到61%;对其进行红外分析,发现存在C=N键吸收峰;热重分析结果,其吸热量明显变小。The Poupuius ussurensis wood with retardant of resin type and low molecular weight PF resin, the retardant of wood is improved largely. When the concentration of retardant was 10%, the oxygen index was 51% ; when the concentration of retardant was 25%, the oxygen index was 61%. Analyze the molecular structure of treated wood with IR, it found that the C = N bond absorption peak.
