Hydraulic polymer cement composition and its construction method

摘要

PROBLEM TO BE SOLVED: To provide a water-hard polymer cement having a small shrinkage stress of a coating film, no peeling of the coating film, high compressive strength, impact resistance and heat impact resistance, and the color tone is not changed by ultraviolet rays and is excellent in appearance. The composition and the construction method thereof are provided. A water-hard polymer cement composition comprising a water-dispersed polyol, a polyisocyanate, an organic metal-based catalyst, a water-hardened cement, and an aggregate, wherein the water-dispersed polyol is water and castor oil-based 3. It is composed of a functional polyol and has a hydroxyl group equivalent of 250 to 600, which is 4 to 10 parts by weight in 100 parts by weight of the entire composition. The polyisocyanate is composed of an aliphatic isocyanurate, and the polyisocyanate is in 100 parts by weight of the entire composition. 5 to 15 parts by weight of the water-hard cement, 5 to 15 parts by weight of the entire composition, and 70 to 85 parts by weight of the aggregate. It is a characteristic water-hard polymer cement composition. [Selection diagram] None
