PLASTIC REFRACTORY HIGH-TEMPERATURE RESISTANT MATERIAL AND REFRACTORY HIGH-TEMPERATURE RESISTANT MORTAR

摘要

The plastic refractory high-temperature resistant material or the refractory high-temperature resistant mortar have a classification temperature of 900 to 1600°C, harden when dried and contain at least two light-weight fillers, a binder, fibers and/or wollastonite as well as water. The light-weight fillers are fly ash cenospheres or blown closed-cell volcanic ash provided with a superficial water-protection layer. An inorganic-organic hybrid binder is used as the binder, said binder containing silicic acid (5) and an acrylate-based polymer (6). The material or the mortar contains white clay or kaolinite and silicon dioxide in the form of silica gel or silica.
