摘要
为了获得抗流失性的木材阻燃剂，首先合成了Ｎ－氰基－Ｎ′－羟甲基胍，并研究了合成反应中各因素对产率的影响，用红外光谱法鉴定该产物的结构。由Ｎ－氰基－Ｎ′－羟甲基胍、蜜胺、磷酸按一定比例配成溶液，在特殊条件下浸注木材，分步干燥、固化处理，获得氨基树脂型阻燃剂。测定阻燃木材的氧指数（ＯＩ）和抗浸提值（ＬＲＶ），当载药量为６和１６ｇ·ｍ￣（－２）兴安落叶松和山杨木氧指８数达到３０；抗浸提值为５２．５６％。结果表明，在特殊条件下用我们合成、复配的木材阻燃剂处理木材，具有较好的抗流失性。
In order to abtain fire retardants to inpart leach resistant to wood,first,we synthetized the N-cyan-N'-hydroxymethy-guanidin and the effect of varions facts to the yield during reaction was researched.The structure of the product was determined by IR-spectrometry.An agueous solution of N-cyan-N'-hydroxymethy -guanidin melamine and phosphoric acid was compounded according to a certain mole ratio,the wood was impregneted with the agueous solution above in certain condition.and was dried step by step,then is cured,the amino-resin fire retardant was obtained.The oxygen index (OI)and the leach resistance value(LRV)was determined.If the amount of fire retardant in dahurian larch and chinese aspen was 6.16 g/m2 respectively,the OI came up to 30.The LRV was 52.56%.Therefore,the fire retardant synthetiaed by us and compounded treating on wood in spacial conditions,is a fire retardant to impart letter leach resistant to wood.
