Abstract

The invention relates to a nanocomposite for thermal insulation especially for fireproofing purposes, which can be obtained by combining (A) at least 35 wt. % of nanoscaled, optionally surface-modified particles of an inorganic compound; (B) 10-60 wt. % of a compound with at least two functional groups which can react and/or interact with the surface groups of nanoscaled particles (A), (C) 1-40 wt. % of water and/or an organic solvent which has no functional groups or only one which is defined in (B), wherein the above-mentioned percentages relate to the sum of components (A), (B) and (C), and (D)=0-10 wt. % (based on the nanocomposite) of additives.
