Abstract

See full text

The present invention relates to a process for producing a hydrophobized shaped thermal-insulation body, comprising pressing or compacting a thermal-insulation mixture containing a silica, an IR opacifier, an organosilicon compound A and an organosilicon compound B, wherein

    organosilicon compound A is hexamethyldisilazane (HMDS) andorganosilicon compound B corresponds to a substance of the formula RnSiX4-n, where R=hydrocarbyl radical having 1 to 18 carbon atoms, n=0, 1 or 2, X=Cl, Br or alkoxy group —OR1 where R1=hydrocarbyl radical having 1 to 8 carbon atoms, or organosilicon compound B corresponds to a silanol of the formula HO[—Si(CH3)2O—]mH, where m=2-100.
