Was developed insulation Board materials of pulverized waste unrecoverable spinning flax and cotton on the basis of urea-formaldehyde and phenol-formaldehyde binder. For material normalized indicators of ognegasitelem. In the work of the received results determine the extent of damage by weight when burning in "ceramic box" samples of composite material with a filler of waste spinning cotton and linen fibers. To reduce the Flammability of the material used, the ammonium fluoride and aluminum trihydrate. The ammonium fluoride as effectively as the trihydrate of aluminium reduces the flammability of the composite material. Composite plate material on the basis of irrevocable pulverized waste spinning cotton and flax fibers with addition of ammonium fluoride trihydrate and aluminum in terms of damage, by mass while burning and time self-combustion meets the Flammability group G1 according to the standard of the Russian Federation 30244-94.
