LAMINATED MOLDED ARTICLE PRODUCTION METHOD, HEAT-SENSITIVE GELLING AGENT, AND LAMINATION MOLDING COMPOSITION
To provide a laminated molded article production method in which the generation of the sagging and collapse of a water curable inorganic composition during lamination is reduced to a practically sufficient level.SOLUTION: Provided is a laminated molded article production method in which lamination molding compositions each contains a water curable inorganic composition and a heat-sensitive gelling agent are laminated, and the lamination molding compositions are made illiquid by heating upon the lamination and/or after the lamination. The heat-sensitive gelling agent comprises: an aqueous medium; a polymer which is dispersed into the aqueous medium; and a nonionic surface active agent which has a cloud point of 30°C or more and an HLB value of 10 to 18. In the heat-sensitive gelling agent, when provided that a penetration resistance value at 17±3°C directly after defoaming is defined as a0 and a penetration resistance value at 17±3°C after microwave heating at 600 W for 30 seconds after the defoaming is defined as a1, a value of the a1/a0 reaches 15 or more.SELECTED DRAWING: None
【課題】積層中の水硬化性無機組成物の垂れや潰れの発生が実用上十分なレベルまで低減された積層造形物の製造方法を提供する。【解決手段】水硬化性無機組成物と感熱ゲル化剤を含有する積層造形用組成物を積層し、積層時及び／又は積層後の加熱により、積層造形用組成物を非流動化させる、積層造形物の製造方法であって、感熱ゲル化剤は、水性媒体と、この水性媒体中に分散されたポリマーと、曇点が３０℃以上且つＨＬＢ値が１０～１８のノニオン界面活性剤とを含有し、感熱ゲル化剤は、脱泡直後の１７±３℃での貫入抵抗値をａ０、脱泡後６００Ｗ３０秒のマイクロウェーブ加熱後の１７±３℃での貫入抵抗値ａ１としたときに、ａ１／ａ０の値が１５以上となる感熱ゲル化剤である、製造方法。【選択図】なし
