Title:
PREPARATION METHOD FOR ADMIXTURE FOR PLASTERBOARD, ADMIXTURE PREPARED THEREBY, AND COMPOSITION FOR FORMING PLASTERBOARD COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/246718
Kind Code:
A1
Abstract:
The present invention relates to a preparation method for an admixture for a plasterboard, an admixture for a plasterboard prepared thereby, and a composition for forming a plasterboard, comprising the admixture. More specifically, the present invention provides a sulfonated polystyrene(SPS)-based compound and relates to a technique that enables regulating of the properties of a plasterboard, such as pore size, flowability, and setting time, by regulating the degree of sulfonation (DS) of the SPS-based compound.
