Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は鋳型製造用洗浄剤に関する。TECHNICAL FIELD The present invention relates to a cleaning agent for mold making.
従来、鋳型を製造する際には樹脂と砂を混合し、これを
反応させ固着させたものを用いている。この時反応物が
模型、金枠、混練砂ホッパー等へ付着してその除去が従
来から問題になっている。特に、鋳型用粘結剤としてフ
ラン樹脂等の有機バインダーを用いた場合、有機バイン
ダーの付着が多いという問題があった。又、鋳型のベン
ド部（空気抜き部）に洗浄しがたい付着が起こりやすい
という問題もある。Conventionally, when a mold is manufactured, a resin and sand are mixed, and the mixture is reacted and fixed to the mold. At this time, the reaction product adheres to a model, a metal frame, a kneading sand hopper, etc., and its removal has been a problem conventionally. In particular, when an organic binder such as a furan resin is used as a binder for a mold, there is a problem that the organic binder is often attached. There is also a problem that it is easy to adhere to the bend part (air vent part) of the mold, which is difficult to clean.
従来、このような付着物を除去する方法として、ハンマ
やブラシ、ショットプラスト等で物理的に除去する方
法、適当な溶媒を溶いて溶解除去する方法等が提案され
ている。Heretofore, as a method for removing such deposits, a method of physically removing with a hammer, a brush, shotplast, etc., a method of dissolving and removing an appropriate solvent, etc. have been proposed.
しかしながら、物理的方法では複雑な構造の鋳型の場
合、人間が手作業で行わざるを得ず、労力と時間を要
し、その上傷が付き易く、最良の方法とは言い難い。溶
媒法では除去に通常１週間以上を要し、しかもしばしば
除去が不完全で、処理後、更にブラッシング等を行う必
要があった。However, in the case of a mold having a complicated structure, it is difficult to say that it is the best method in the case of a mold having a complicated structure, because a human has to do it manually, which requires labor and time, and is easily scratched. In the solvent method, the removal usually requires one week or more, and often the removal is incomplete, and it is necessary to further brush after the treatment.
又、特開昭59-153542 号公報には、ジメチルスルホキシ
ドと、フッ素系界面活性剤、炭化水素系アニオン界面活
性剤等の界面活性剤を含有する鋳型付着物除去剤が開示
されている。しかしながら、この除去剤も十分に付着物
を除去することができない。Further, JP-A-59-153542 discloses a template deposit removing agent containing dimethylsulfoxide and a surfactant such as a fluorine-based surfactant and a hydrocarbon-based anion surfactant. However, this removing agent also cannot sufficiently remove the deposits.
