FIELD: chemistry.
SUBSTANCE: invention relates to production of polymer composites based on foam polyurethanes, which can be used for heat insulation of structures in shipbuilding, aircraft construction and motor industry. A method of producing foam polyurethane nanocomposite includes preliminary mechanical activation of a nanomodifier, followed by addition thereof into a hydroxyl-containing ester under the effect of ultrasound in amount of 0.5-3.0% relative to the weight of the obtained nanocomposite, mixing and adding a curing agent. The nanomodifier used is zirconium dioxide which is stabilised with yttrium oxide or aluminium oxide.
EFFECT: method improves mechanical properties of the material and raises its ignition point.
