METHOD OF OBTAINING LOW-DIMENSIONAL FILLING MATERIALS FROM NATURAL LAYER MINERALS FOR POLYMER MATERIALS Russian patent published in 2008 - IPC C09C3/04 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention pertains to the method of obtaining low-dimensional filling materials, which can be used in engineering materials for making composite materials with given functional characteristics. The method involves grinding the raw materials of the layer mineral and thermal treatment of the ground up dispersed particles. Thermal treatment is done by putting the dispersed particles into a non-oxidising thermal gas stream with density of 3·10⁶-8·10⁷ W/m² for a period of 10^-4-10^-3 s. The above mentioned stream, containing dispersed particles, is applied to a substrate in form of a steel sheet, heated to 20-100°C. The obtained particles are collected and cooled down to 100-120°C.

EFFECT: invention allows obtaining a filling material with size of not more than 10 nm, with low energy consumption, and is effective when making polymer nano-composites.
