AQUEOUS RESIN DISPERSION FOR CEMENT, SULFURIC ACID RESISTANT MODIFIER FOR CEMENT, COMPOSITION, CURED PRODUCT AND MANUFACTURING METHOD THEREOF, AND SULFURIC ACID RESISTANT MODIFICATION METHOD
PROBLEM TO BE SOLVED: To provide an aqueous resin dispersion for cement capable of causing a mortar to exhibit excellent sulfuric acid resistance.SOLUTION: An aqueous resin dispersion for cement is obtained by polymerizing a polymerizable monomer mixture including alkoxysilane group-containing polymerizable monomer, styrene, and butadiene, and includes polymer with calculated glass transition temperature of -20°C or higher and 20°C or lower, and nonionic surfactant. The polymerizable monomer mixture includes, with regard to the total amount of the polymerizable monomer, the alkoxysilane group-containing polymerizable monomer of 0.1 mass% or more and 5.0 mass% or less.SELECTED DRAWING: None
【課題】少なくともモルタルに優れた耐硫酸性を発現させることができるセメント用水性樹脂分散体を提供する。【解決手段】アルコキシシラン基含有重合性単量体と、スチレンと、ブタジエンと、を含む重合性単量体混合物を重合して得られ、かつ、計算ガラス転移温度が−２０℃以上２０℃以下である重合体と、ノニオン性界面活性剤と、を含み、当該重合性単量体混合物は、該重合性単量体混合物の総量に対して、当該アルコキシシラン基含有重合性単量体を０．１質量％以上５．０質量％以下含む、セメント用水性樹脂分散体。【選択図】なし
