    • @ Non-blooming fire retardant compositions are disclosed comprising an ammonium phosphate-containing fire retardant and an effective amount of boric acid or an alkali metal borate. The ammonium phosphate-containing fire retardant preferably comprises the reaction mixture of aqueous phosphoric acid and an alkylene oxide. Preferably, the boric acid or alkali metal borate is present in an amount of from about 2.5% to about 12% by weight of solids in the phosphate-containing fire retardant. Such compositions are less susceptible to exudation of the fire retardant from treated wood panels during drying of the panels at elevated temperatures, and are particularly suitable for use in continuous treatment processes.
    • 公开了包含含磷酸铵的阻燃剂和有效量的硼酸或碱金属硼酸盐的非开花阻燃剂组合物。 含磷酸铵的阻燃剂优选包含磷酸水溶液和环氧烷烃的反应混合物。 优选地,硼酸或碱金属硼酸盐以含磷酸盐阻燃剂中固体重量的约2.5%至约12%的量存在。 这样的组合物在升高的温度下在面板的干燥期间不太容易从经处理的木板中渗出阻燃剂,并且特别适用于连续处理工艺。
