The preparation process of nanopartu00ecculas flakes, and nanopartu00ecculas flakes

摘要

The preparation process of nanopartu00ecculas flakes, and nanopartu00ecculas flakes.The present invention relates to a process for the preparation of nanoparticles in slides, said process comprising the following steps of: a) mixing a material laminated with a blowing agent selected among polyols, (b) to the rolled material react with expanded. An agent of the graft in the presence of water and an acid.The said agent responding to the general formula R ~ ~ x ~ 4 ~ in which R represents a hydrogen atom or a hydrocarbon radical containing 1 to 40 carbon atoms, clusters R may be identical or different, X represents an atom of silicon, zirconium or titanium, y is a Alcu00f3xi group containing 1 to 12 carbon atoms, or a halogen, and is equal to 1, 2 or 3.(c) and recover the nanoparticles in slides. The nanoparticles obtained are intended mainly for polymer reinforcement.
