PROCESS FOR PRODUCING INSULATING MATERIALS AND PRODUCTS THEREOF

摘要

A process for producing a thermal insulating calcium hydrosilicate compound comprises the steps of: providing a source of calcium ions; providing a silica compound; providing a stabilizing reagent; providing a fibrous compound; forming an aqueous mixture of the source of calcium ions the silica compound, the stabilizing reagent and the fibrous component; and hydrothermally treating the aqueous mixture at a pressure above 12,5 bars but not over 20 bars in the presence of saturated steam at a temperature from about 190 to 212 DEG C to produce a calcium hydrosilicate compound.
