METHOD FOR PREPARING COMPOSITION RADIATION-CROSS-LINKED FOAM POLYETHYLENE OF REDUCED INFLAMMABILITY Russian patent published in 2007 - IPC C08J9/236 C08J9/22 B32B7/12 B32B27/32 C09J201/00 

FIELD: chemistry of polymers, chemical technology.

SUBSTANCE: invention relates to heat-insulating and sound-suppressing materials of reduced inflammability, namely to materials based on radiation-cross-linked foam polyethylene. Reduced inflammability is provided by addition of antipyrens of radical-inhibitory type wherein bromo-containing compounds with additives or without additives of antimony oxide are used. Additives are added between fragments of milled radiation-cross-linked foam polyethylene by addition of glue layer comprising antipyrene followed by lamination of fragments of milled foam polyethylene treated by such manner. Prepared material based on radiation-cross-linked foam polyethylene possesses the reduced inflammability, small specific weight and low heat conductivity coefficient.

EFFECT: improved preparing method.
