| Zusammenfassung: | To provide a mold material for shell molding that allows for securing favorable work environment for a worker and exhibiting a sufficient strength of a finally obtainable mold, even in the case of molding using one that time has been comparatively elapsed from a production besides at a production thereof.SOLUTION: A mold material for shell molding comprises a cure accelerator having a 0.01 mol/l aqueous solution pH of 2.0-12.0 as a requisite constituent component, together with refractory aggregate, phenol resin and aromatic deodorizer.SELECTED DRAWING: None
【課題】その製造時のみならず、製造から比較的時間が経過したものを用いて造型する場合にあっても、作業者にとって良好な作業環境の確保が可能ならしめられると共に、最終的に得られる鋳型が十分な強度を発揮する、シェルモールド用鋳型材料を提供すること。【解決手段】耐火性骨材と、フェノール樹脂と、香料系消臭剤と共に、０．０１ｍｏｌ／ｌ水溶液のｐＨが２．０～１２．０である硬化促進剤を必須の構成成分として、シェルモールド用鋳型材料を構成した。【選択図】なし |
