COMPOSITION FOR PREPARING FOAM PLASTIC Russian patent published in 2003 - IPC

FIELD: technical compositions. SUBSTANCE: invention relates to compositions used for preparing foam plastic and exploited at temperatures below 150 C under enhanced requirements to vibroresistance and they can be used in machine engineering and aviation technique. The composition comprises the following components, mas. p. p. : phenol resin, 80-120; nitrile rubber, 10-30; urotropin, 8-12; sulfur, 0.2-0.5; blowing agent, 3-7 and phosphorus-containing antipyrene in carbamide envelope, 12-35.5. Invention allows preparing foam plastic and articles based on thereof with reduced inflammability and enhanced impact viscosity that results to the enhanced safety and exploitation working life of article in aviation technique. EFFECT: enhanced and improved properties of composition. 2 cl, 2 tbl, 4 ex
