The granted patent US11987528B2 outlines a novel process for producing a hydrophobized shaped thermal-insulation body. The process involves pressing or compacting a thermal-insulation mixture that consists of specific components: 30% to 95% by weight of silica, 5% to 50% of an infrared (IR) opacifier, 1% to 20% by weight of two distinct organosilicon compounds (hexamethyldisilazane and another organosilicon compound defined by a specific formula), and 0.1% to 10% by weight of water. The resulting thermal-insulation body is characterized by a density ranging from 50 to 300 g/l and a compressive strength between 65 to 150 kPa. The patent also specifies that the silica can be selected from various forms, including aerogels and fumed silicas, while the IR opacifier can include materials such as titanium dioxide and carbon blacks.
Further details in the claims highlight additional parameters for the process, including the molar ratio of the organosilicon compounds and water, the temperature range for preparing the mixture, and the time constraints for mixing and pressing. The process also includes a maturation step at temperatures between 20° C. to 80° C. for 1 to 24 hours, followed by a heat treatment at temperatures of 90° C. to 200° C. for a similar duration. The claims emphasize the versatility of the thermal-insulation mixture, allowing for the inclusion of fibers and specifying the conditions under which the mixture is prepared and processed, thereby enhancing the performance characteristics of the final thermal-insulation product.
