Binder preparation for producing thixotropic, fire-resistant, carbon-containing casting compositions

摘要

The invention relates to a binder preparation for producing carbon-containing, fire-resistant casting compositions of high thixotropy. It contains carboxylic acids, especially polymeric carboxylic acids and hydroxycarboxylic acids, and also reactive aluminium compounds and amorphous silica. The highly thixotropic casting compositions which can be made up with a little water, can be compacted to a low porosity by intensive vibration.
