Filed: 2004-07-13
Granted: 2006-02-10
Abstract: FIELD: production of composite materials on base of polymer material at preset functional characteristics. 
     SUBSTANCE: proposed method includes subjecting the ground fractions of natural laminar minerals to thermal shock continued for 1.0-30 min at temperature gradient  no less than 800-1000°C.  Proposed method includes mechanical grinding, separation and heat treatment by introducing the weighed portion into working space of heating appliance for realization of thermal shock. To increase gradient of thermal shock, ground semi-finished product is additionally subjected to  treatment at temperatures of (-)60-(-)195°C. To enhance efficiency of grinding, semi-finished product is heated to 100-300°C before low-temperature treatment and cycle "heating-cooling-heat treatment by thermal shock" is repeated at least twice. Proposed method makes it possible to obtain dispersed powders at size no more than 10 nm. 
     EFFECT: reduced power requirements; enhanced efficiency of nano-composites.
