水硬性ポリマーセメント組成物及びその施工方法
Document Type and Number:
Japanese Patent JP7245134
Kind Code:
B2
Abstract:
To provide: a hydraulic polymer cement composition, the film of which has small shrinkage stress and does not detach, has high compression strength, impact resistance, and thermal shock resistance, the color tone of which does not change by ultraviolet rays, and has excellent appearance; and a construction method of the same.SOLUTION: Provided is a hydraulic polymer cement composition comprising a water dispersion polyol, a polyisocyanate, an organic metal-based catalyst, hydraulic cement, and aggregates. The water dispersion polyol comprises water and a castor oil-based trifunctional polyol and has a hydroxyl equivalent of 250 to 600 with a content of 4 to 10 pts.wt. per 100 pts.wt. of a whole composition. The polyisocyanate comprises an aliphatic isocyanurate with a content of 5 to 15 pts.wt. per 100 pts.wt. of the whole composition. The content of hydraulic cement is 5 to 15 pts.wt. per 100 pts.wt. of the whole composition and the content of the aggregate is 70 to 85 pts.wt. per 100 pts.wt of the whole composition.SELECTED DRAWING: None
