Title:
HYDRAULIC COMPOSITION FOR ADDITIVE MANUFACTURING DEVICE, AND METHOD FOR MANUFACTURING CASTING MOLD
Document Type and Number:
WIPO Patent Application WO/2019/026841
Kind Code:
A1
Abstract:
The present invention is a hydraulic composition for an additive manufacturing device, the composition having superior dimensional stability and initial flexural strength, and the composition including 1.5-14 parts by mass of a polymer per 100 parts by mass of an inorganic binder. The present invention preferably is a hydraulic composition for an additive manufacturing device, the inorganic binder including 50-100 mass% of calcium aluminates, where the entirety of the inorganic binder is 100 mass%, and more preferably is a hydraulic composition for an additive manufacturing device, the inorganic binder including 0-50 mass% of a rapid-hardening cement, where the entirety of the inorganic binder is 100 mass%.
