| description | To provide a lamination molding method capable of solving an issue of clogging of a nozzle when discharging a binder from the nozzle and elongation of a storage period of the binder by increasing a curing speed.SOLUTION: In a lamination molding method, a curing agent comprising a mixture of phosphoric acid, p-toluenesulfonic acid and pure water and a sand material are mixed, heated and dried, a binder comprising furfuryl alcohol, an acid catalyst, a phenolic compound and polyoxymethylene is discharged from a nozzle, and the binder reacts with the surface of the sand material uniformly coated with the curing agent to cure the sand mold.SELECTED DRAWING: Figure 1
【課題】ノズルからバインダーを吐出する際のノズルの目詰まりの問題を解消し、また硬化速度を高めてバインダーの保存期間を延ばす、積層造形方法を提供する。【解決手段】リン酸、ｐ－トルエンスルホン酸、純水の混合物からなる硬化剤と砂材を混合し、加熱、乾燥させた後、フルフリルアルコール、酸触媒、フェノール類化合物、及びポリオキシメチレンからなるバインダーをノズルから吐出し、前記バインダーと前記硬化剤で均一に被覆された前記砂材の表面とが反応することで砂型を硬化させる。【選択図】図１ |
