The present invention relates to a method for manufacturing an admixture for gypsum board, an admixture for gypsum board according thereto, and a composition for forming a gypsum board comprising the same. In detail, by controlling the DS (degree of sulfonation) of the sulfonated polystyrene (SPS)-based polymer compound and the type and polymerization degree of the monomers contained in the polymer compound, the admixture properties such as fluidity, setting time, and bubble size of the gypsum slurry We want to provide controllable technology. |
