CURING ACCELERATOR COMPOSITION AND ACCELERATION METHOD FOR HYDRAULIC POLYMER CEMENT COMPOSITION FOR FLOOR COATING
PROBLEM TO BE SOLVED: To provide a curing accelerator composition and acceleration method enabling, even under any temperature of 15°C or less, a hydraulic polymer cement composition for floor coating to have so-called pot life sufficient to be applied on a base concrete after mixing the materials, to be cured within 8 hours so as to become usable as a coated floor, and to result in a coating (coated floor) which does not suffer swelling or foaming (pinholes) due to the carbonic acid gas or the like and which performance as the coating (coated floor) does not deteriorate.SOLUTION: The curing accelerator composition for a hydraulic polymer cement composition for floor coating that contains polyol, a polyisocyanate, a diluent, a cement, an aggregate and water, comprises 2-(dimethylamino) ethanol and N-(3-aminopropyl) morpholine, and consists of 45 to 65 parts by weight of 2-(dimethylamino) ethanol and 35 to 55 parts by weight of N-(3-aminopropyl) morpholine.SELECTED DRAWING: None
【課題】１５℃以下のいずれの温度下においても、材料を混合後に下地コンクリート上に施工可能な所謂可使時間を十分に有すると共に８時間以内に硬化して塗り床として使用が可能となり、硬化後の塗膜（塗り床）に炭酸ガス等による膨れ、発泡（ピンホール）がなく、さらには塗膜（塗り床）の性能が低下することがない、塗床用水硬性ポリマーセメント組成物の硬化促進剤組成物及び硬化促進方法を提供する。【解決手段】ポリオール、ポリイソシアネート、希釈剤、セメント、骨材及び水を含有してなる塗床用水硬性ポリマーセメント組成物の硬化促進剤組成物であって、２−（ジメチルアミノ）エタノールとＮ−（３−アミノプロピル）モルホリンとから成り、２−（ジメチルアミノ）エタノールは４５〜６５重量部、Ｎ−（３−アミノプロピル）モルホリンは３５〜５５重量部から成ることを特徴とする塗床用水硬性ポリマーセメント組成物の硬化促進剤組成物である。【選択図】なし
