PROBLEM TO BE SOLVED: To provide acrylic resin emulsion for cement mixing superior to reforming characteristics of cement and preventing gelation and sudden body up when mixed with the cement.SOLUTION: Acrylic resin emulsion for cement mixing which contains acrylonitrile or hydroxyl group based monomer as modacrylic monomer, uses nonionic surfactant having a reactive unsaturated group as emulsifier, the glass transformation temperature is more than -30°C, and dilation of dried coating is not less than 1000% and the coating strength is not less than 0.2 MPa is used as cement mixing agent.SELECTED DRAWING: None
【課題】セメントの改質性に優れ、セメントとの混和の際にゲル化や急激な増粘が生じにくいセメント混和用アクリル樹脂エマルジョンを提供する。【解決手段】アクリル系単量体として、アクリロニトリルまたは水酸基含有単量体を含み、反応性不飽和基を有するノニオン性界面活性剤が乳化剤として用いられ、ガラス転移温度が−３０℃以上であり、乾燥皮膜の伸びが１０００％以上かつ皮膜強度が０．２MPa以上であることを特徴とするセメント混和用アクリル樹脂エマルジョンをセメント混和材として用いる。【選択図】なし
