摘要:
An intumescent, fire-retardant, aqueous composition which comprises (a) as a flameproofing agent, a water-soluble ammonium salt of a non-volatile inorganic acid, such as sulfamic acid, sulfuric acid or, in particular, phosphoric acid, (b) as a blowing agent, a water-soluble nitrogen compound, for example urea, which can be methylolated, or its derivatives and salts and (c) dextrin as a binder, (d) if desired, formaldehyde, and (e) if desired, further additives, for example wood preservatives, is used for the flameproof and heat-resistant treatment of very diverse substrates, preferably building timber, or for extinguishing burning substrates of all kinds. When the composition is used as a fire-extinguishing agent, it preferably additionally contains a foaming agent, and can contain a foam stabilizer.
摘要:
Composition for flameproofing organic fibre material which contains at least1. a tetrakis-(hydroxymethyl)-phosphonium compound, its self-condensation product or its condensation product with a reactive nitrogen compound2. an aliphatic amide or an imidazole or an imidazoline as agent for imparting a soft handle3. a methylolated amino groups containing 1,3,5-triazine and, optionally,4. an optionally methylolated and esterified derivative of a urea and, optionally,5. a low molecular amine.These compositions yield flameproof finishes paired with a soft handle especially on polyester-cotton blends.
