Flame-retardant compositions of methanephosphonic acid, boric acid and an organic base |
摘要 |
Compositions are described that are obtainable by preparing a mixture of methanephosphonic acid, boric acid, water and optionally urea and subsequently adding dicyandiamide and/or guanylurea to this mixture. The compositions thus obtained are useful for conferring a flame-retardant finish on fibrous materials, especially on woven fabrics composed of cellulosic fibers.
