PROCESS FOR PRODUCING NANOSCALE, PRIMARY-COATED HYDROTALCITE AND HYDROTALCITE

摘要

The present invention relates to a process for producing coated, nanoscale hydrotalcite, wherein the individual primary nanoscale hydrotalcite particles have been coated. For this purpose, in accordance with the invention, additives are used in the precipitation reaction in order to obtain the corresponding hydrotalcite particles in coated, nanoscale form. In this case, each primary particle has its own coating. In a further aspect, the application is directed to coated primary, nanoscale hydrotalcite particles, especially those obtainable by the process according to the invention. A further aspect of the invention is directed to composites comprising nanoscale hydrotalcites, especially hydrotalcites produced according to the present invention. Finally, the present application is directed to compositions comprising mixtures of magnesium hydroxide and hydrotalcite.
