Process for producing silicatic moldings

Abstract

The invention relates to a process for producing a molding, characterized in that a silicatic solid is mixed with a solution comprising a first silicatic binder and the mixture is then press-molded, and the compression molding is then post-treated with a solution comprising a second silicatic binder, and to silicatic moldings obtainable by this process, and also to their use as construction material, insulator material, gasket material or fire-resistant material.

1 - 12 . (canceled)  
   
   
       13 . A molding obtained by the process which comprises 
 (a) mixing a silicatic solid with a solution containing a first silicatic binder, and thereby forming a mixture;    (b) press-molding the mixture, and forming a compression molding; and    (c) post-treating the compression molding with a solution containing a second silicatic binder, wherein the second silicatic binder comprises a binder having a modulus that is at least 10.    
   
   
       14 . A molding comprising: 
 (a) from 2 to 60% by weight of silicatic binders, based on the total weight of the molding; and    (b) from 60 to 98% by weight of silicatic solid, based on the total weight of the molding.    
   
   
       15 . Insulator material or fire-resistant material comprising one or more moldings according to  claim 13 .  
   
   
       16 . Support panel comprising one or more moldings according to  claim 13 .  
   
   
       17 . A molding consisting essentially of silicatic components.  
   
   
       18 . A molding according to  claim 17 , wherein the content of organic components is less than 2% by weight, based on the total weight of the molding.  
   
   
       19 . A molding according to  claim 17 , having a total content of silicatic binders of 2 to 40% by weight, based on the total weight of the molding, and a content of a silicatic solid of 60 to 98% by weight, based on the total weight of the molding, with the proviso that the sum of the two contents is 100% by weight.  
   
   
       20 . Insulator material or fire-resistant material comprising one or more moldings according to  claim 17 .  
   
   
       21 . Support panel comprising one or more moldings according to  claim 17.
