AQUEOUS RESIN DISPERSION FOR MORTAR, MORTAR COMPOSITION AND MORTAR CURED ARTICLE
PROBLEM TO BE SOLVED: To provide an aqueous resin dispersion for mortar having improved thick coating drip property, long usable life and capable of exhibiting excellent adhesiveness in a mortar for repairing material, a mortar for finishing material, a mortar for adhesive or the like.SOLUTION: There is provided an aqueous resin dispersion for mortar containing water, polymer particles having calculated glass transition temperature of -15°C to +30°C, a core part and a shell part, and a nonionic surfactant (d) of 0.1 pts.mass to 6.0 pts.mass based on 100 pts.mass of the polymer particles, where the polymer particles are obtained by polymerizing a nitrile-containing vinyl monomer (a), a reactive surfactant (b) and a polymerizable monomer (c) copolymerizable with one or more kinds of the nitrile-containing vinyl monomer (a) and the reactive surfactant (b), and a component by polymerizing the nitrile-containing vinyl monomer (a) positions only at the core part of the polymer particles.SELECTED DRAWING: None
【課題】補修材用モルタル、仕上げ材用モルタル、接着用モルタル等において、厚塗りダレ性が改善され、可使時間が長く、優れた接着性を発現できるモルタル用水性樹脂分散体を提供する。【解決手段】水と、計算ガラス転移温度が−１５℃以上＋３０℃以下であり、コア部とシェル部とを有する重合体粒子と、前記重合体粒子１００質量部に対して０．１質量部以上６．０質量部以下のノニオン性界面活性剤（ｄ）と、を含み、前記重合体粒子が、ニトリル含有ビニル系単量体（ａ）と、反応性界面活性剤（ｂ）と、ニトリル含有ビニル系単量体（ａ）及び反応性界面活性剤（ｂ）のいずれか１種以上と共重合可能な重合性単量体（ｃ）と、を重合して得られ、ニトリル含有ビニル系単量体（ａ）が重合した成分は、前記重合体粒子のコア部のみに位置する、モルタル用水性樹脂分散体。【選択図】なし
