摘要:
The present invention relates to a method for the flame-retardant processing of textile materials, wherein said method first comprises impregnating said materials with a melamine-type resin or with organosilicone-containing substances. The materials are further impregnated with a solution of a complex compound comprising an ammonia salt of amidoalkylphosphonic acid with ammonium chloride. The materials processed according to this method have a reduced combustibility while the gases produced during combustion have a low toxicity.
摘要:
A description is given of a new combustion retardant for polymer materials, consisting of methyl(oxyalkyl)phosphono-oxyethylene methacrylate of the formula
CH 2 =C(R)-C(O)[0CH 2 CH 2 OP(O)(R)(OR 1 )]
where R - CH 3 ; R 1 - CH 3 , C 2 H 5 , C 3 H 7 , C 4 H 9 . The combustion retardant can be used primarily as a comonomer in the process of copolymerisation with methyl methacrylate, and also to impart fireproofing properties to chemical fibres. In the latter case, the method of inoculation polymerisation is used.
摘要:
The invention relates to compositions for the application of coatings primarily to wood and metal structures and installations, which have high fireproofing and thermal insulation properties, and can be used in construction, the aircraft industry, rail transport and shipbuilding. The composition includes a foaming system, which itself includes pentaerythritol or sorbitol, ammonium polyphosphate, boric acid, urea, filler and pigment, and also resin as a binder.

摘要:
A process is proposed for the fireproofing treatment of textile materials by impregnating them initially with a melamine-type resin or organosilicon substances, and then with a solution of a complex compound of the ammonia salt of amidoalkylphosphonic acid with ammonium chloride. Materials treated in accordance with the invention have reduced combustibility and low toxicity of the gases given off during combustion.
