METHOD OF PREPARING NANO-COMPOSITE MATERIAL Russian patent published in 2010 - IPC C08J5/00 C08J5/16 B82B3/00 C08L23/06 

FIELD: chemistry.

SUBSTANCE: method involves mixing nanofiller with binder, mechanical activation of the obtained mixture and final moulding of the mixture. The powdered filler and binder undergo combined preliminary mechanical activation to obtain a concentrate. The concentrate is a powdered mixture of components with ratio binder: filler equal to 50:50. Further, the obtained concentrate is mixed with binder in amount of 100 pts. wt binder per 0.1-2.0 pts. wt concentrate to obtain a second mixture. This mixture undergoes traditional mixture in a bead mill for a period of time sufficient for obtaining a homogeneous mixture. The powdered mixture is then hot-moulded at pressure and temperature at which the mixture turns into a fluid. Further, the mixture is kept under these conditions until complete solidification. The binder used is powdered polypropylene.

EFFECT: method enables to obtain antifriction material, characterised by high strength properties and wear resistance, elasticity and low brittleness.
