Abstract

THE INVENTION GENERALLY PROVIDES GYPSUM-CONTAINING SLURRIES INCLUDING STUCCO, NAPHTHALENESULFONATE DISPERSANT, AND PREGELATINIZED STARCH. THE NAPHTHALENESULFONATE DISPERSANT IS PRESENT IN AN AMOUNT OF ABOUT 0.1%-3.0% BY WEIGHT BASED ON THE WEIGHT OF DRY STUCCO. THE PREGELATINIZED STARCH IS PRESENT IN AN AMOUNT OF AT LEAST ABOUT 0.5% BY WEIGHT UP TO ABOUT 10% BY WEIGHT OF PREGELATINIZED STARCH BY WEIGHT BASED ON THE WEIGHT OF DRY STUCCO IN THE FORMULATION. OTHER SLURRY ADDITIVES CAN INCLUDE TRIMETAPHOSPHATE SALTS, ACCELERATORS, BINDERS, PAPER FIBER, GLASS FIBER, AND OTHER KNOWN INGREDIENTS. THE INVENTION ALSO COMPRISES THE GYPSUM-CONTAINING PRODUCTS MADE WITH SUCH SLURRIES, FOR EXAMPLE, GYPSUM WALLBOARD, AND A METHOD OF MAKING GYPSUM WALLBOARD.
