METHOD OF PRODUCING LAYERED NANOPARTICLES AND OBTAINED NANOPARTICLES Russian patent published in 2011 - IPC C09C1/42 C09C1/00 C09C3/12 C08K9/06 B82B1/00 

FIELD: chemistry.

SUBSTANCE: in order to obtain layered nanoparticles, layered material selected from clay and boehmite is mixed with a separating agent selected from diols. The separated layered material reacts with a cross-linking agent in the presence of water and acid. The cross-linking agent has formula R_aXY_4-a, in which R is a hydrogen atom or a hydrocarbon radical containing 1-40 carbon atoms, and groups R can be identical or different, X is a silicon, zirconium or titanium atom, Y is an alkoxy group containing 1-12 carbon atoms, or a halogen, and a equals 1, 2 or 3. The obtained layered nanoparticles are separated. The loss on ignition value of the layered nanoparticles is higher than 6%, preferably higher than 12% and even more preferably higher than 16%.

EFFECT: invention increases distance between layers of layered nanoparticles meant for reinforcing polymers.
