Title:
DISPERSANT COMPOSITION FOR HYDRAULIC COMPOSITIONS FOR CENTRIFUGAL MOLDING
Document Type and Number:
WIPO Patent Application WO/2021/070699
Kind Code:
A1
Abstract:
Provided are: a dispersant composition for hydraulic compositions for centrifugal molding, the dispersant composition enabling a hydraulic composition to exhibit better moldability for a predetermined time (e.g., 15 minutes to 60 minutes) from kneading; a method for producing same; a hydraulic composition for centrifugal molding which exhibits better moldability for a predetermined time (e.g., 15 minutes to 60 minutes) from kneading; and a method for producing a cured product of a hydraulic composition. This dispersant composition for hydraulic compositions for centrifugal molding contains the following component (A) and water. Component (A): a copolymer (A) containing a monomer (A1) represented by general formula (A1), a monomer (A2) represented by general formula (A2), and a monomer (A3) represented by general formula (A3) as constituent monomers and having a molecular weight of 10,000 to 70,000, the monomer (A1) being present in an amount of 30 mol% to 70 mol% of the constituent monomers of the copolymer, the monomer (A2) being present in an amount of 10 mol% to 50 mol%, the monomer (A3) being present in an amount of 20 mol% to 35 mol%.
