COMPOSITION FOR PRODUCING FOAM PLASTIC Russian patent published in 2013 - IPC C08L61/10 C08L9/02 C08K5/16 C08K5/5399 C08J9/06 

FIELD: chemistry.

SUBSTANCE: invention relates to aircraft engineering, mechanical engineering and specifically to light, impact resistant, non-flammable foam materials which can be used as structural and heat-insulation aggregates, as well as in making components of "unsinkable" structures with a low water- and fuel-absorption coefficient, for example, float level gauges of fuel tanks of engine units. Disclosed is a composition for producing foam plastic having the following chemical composition, pts.wt: phenol novolac resin 20-40, phenol resol resin 60-80, nitrile rubber 20-40, urotropin 3-10, foaming agent 15-20, aluminium nitrilotrimethylphosphonate fire retardant 3-10. The technical result is high impact viscosity and low fuel-absorption of the foam plastic.

EFFECT: use of the disclosed foam plastic increases reliability of aircraft engineering articles and widens the field of use of said foam plastic.
