ABSTRACT:
A moldable refractory composition containing from about 42 to about 83% by weight of a liquid vehicle, such as water; from about 13 to 50% by weight of ceramic fiber; from about 0.5 to 7% by weight of an inorganic binder derived from an inorganic colloidal dispersion having active hydroxyl groups capable of reacting with hydroxyl groups of the ceramic fiber; and from about 0.5 to 5% by weight of a high molecular weight organic resin which serves multiple functions including tackifier of the wet composition, cohesiveness of the wet composition, appropriate rheology of the wet composition to provide shelf life and a wide range of applications and in dry composition to provide green strength. Also described is the method of manufacture for the subject refractory moldable composition. Upon drying, the moldable composition adheres well to surfaces such as those encountered in furnacing applications and construction applications to metals and other ceramic materials and dries to give an essentially crack-free refractory shape which exhibits greater resilience than heretofore known moldable refractory compositions. The dried moldable composition is useful as thermal insulation at temperatures up to 1650.degree. C. (3000.degree. F.) dependent upon the type of ceramic fibers and inorganic binders contained as ingredients in the composition.
