摘要
LFP—86型木材阻燃剂是一种含有氮、磷的微黄色透明液体。试验证明,LFP-86型阻燃剂处理的水曲柳材的氧指数为57,达到JIS D1201—77难燃一级水平。当木材的阻燃剂吸收量达60kg/m^3以上,在1000℃燃烧3分钟后的失重率为20%左右。LFP—86型阻燃剂不抗菌、不防蚁。阻燃材的冲击韧性、胶合强度、抗吸湿性稍有降低,对油漆、金属腐蚀无影响。LFP—86型阻燃剂适用于室内木材的阻燃处理。
The LFP-86 fire retardant is a light yellow transparent, liquor which contains N and P. Theresult obtained from experiments on treating wood of Fraxinus mandshurica indicates that the oxygen index of LFP-86 fire retardant is 57 and the retardancy of LFP-86 treated wood meets class I according to JIS D 1201, When the intake of LFP-86 fire retardant is over 60kg/m_3and temperature up to 1000℃, the rate of weightloss will be about20% after bur ning 3 rains LFP-86 fire retardant has no ability to defend fungi and ter mites attack In impact bending,bonding strengthand hygrosscopicity resistance, treated woods are lower than untreated woods. LFP-86 has no effects on paintability and corrosivity. There are indications that LFP-86 may be used as a fire retardant for indoor timber and woodcrafts.
