为了获得抗流失性木材阻然剂．并为实现木材工业化的阻燃处理．首先以廉价的尿素为原料、合成了一经甲基脲（ＨＭＵ）；对ＨＭＵ、蜜胺（ＭＡ）、磷酸氢二铵（ＤＡＰ）的配比、处理木材的压力、时间进行了正交实验；测定了阻燃木材的载药率和氧指数以及阻燃剂的抗浸提值。结果表明：影响阻燃性的显著因子是浸药时间．三组分配比影响最小，ＨＭＵ、ＭＡ、ＤＡＰ的较佳配比为５：１：６．５。较佳的阻燃处理条件：压力为６００～１３００Ｐａ，时间为３０ｈ左右、温度为５０℃。当兴安落叶松载药率为０．６３％时，氧指数达到３０，抗浸提值为３６．８８％。该木材阻燃剂具有较好的阻燃性和一定的抗流失性，所选择的阻燃处理条件可作为工业生产的参考。
In order to obtain resistance to loss of wood resistance agent. And for the realization of wood industrial flame retardant treatment. First of all, urea (urea) was used as a raw material to synthesize a methyl urea (HMU). The orthogonal experiment was carried out on the ratio of HMU, melamine (MA) and diammonium phosphate (DAP) The loading rate and oxygen index of flame-retardant wood and the anti-leaching value of flame retardant were determined. The results show that: a significant factor affecting the flame retardancy is the soaking time. The three groups had the least impact on the ratio of HMU, MA and DAP, which was 5: 1: 6.5. The preferred flame retardant treatment conditions: a pressure of 600 ~ 1300Pa, a time of about 30h, a temperature of 50 ℃. When the loading rate of Larix gmelinii was 0.63%, the oxygen index reached 30, anti-leaching value of 36.88%. The wood flame retardant has a good flame retardancy and a certain resistance to loss, the selected flame retardant processing conditions can be used as a reference for industrial production.
