Description
樹脂と鋳物砂の硬化物を鋳型として用いる鋳造法は、まず樹脂と鋳物砂を混合したものを金型に充填し、アミン類や熱等によって硬化させ、鋳型を形成する。次に鋳型を金型から取り外し、高温で融解させた金属を鋳型に流しこみ、金属が硬化した後、鋳型から金属を取り出す。 In a casting method using a cured product of resin and foundry sand as a mold, a mold is first filled with a mixture of resin and foundry sand and cured by amines or heat to form a mold. Next, the mold is removed from the mold, and the metal melted at a high temperature is poured into the mold. After the metal is cured, the metal is taken out from the mold.
固着物除去にはハンマー、ブラシ、エアブラスト等の物理的方法を用いる方法や、適当な溶媒を用いて溶解または膨潤させて除去する方法、もしくはこの二つを組み合わせた方法等が用いられている。複雑な構造の金型では、自動洗浄による方法だけでは固着物の除去が困難である。そこで手作業による固着物の除去が必要になる場合もあり、手作業の時、人が洗浄液と接触する頻度が増すため、洗浄液は有害性が低いものが好ましい。また洗浄分野では有害性が懸念される溶媒は使用が控えられ、有害性の低い洗浄溶媒へ移行する傾向がある。 For removing the fixed matter, a method using a physical method such as a hammer, brush, air blast, a method of removing by dissolving or swelling using an appropriate solvent, or a method combining these two methods is used. . In a mold having a complicated structure, it is difficult to remove the sticking matter only by the automatic cleaning method. Therefore, there are cases where it is necessary to remove the fixed matter by manual work, and during manual work, the frequency with which a person comes into contact with the cleaning liquid increases. Therefore, it is preferable that the cleaning liquid has low toxicity. In the cleaning field, use of solvents that may be harmful is refraining from use, and there is a tendency to shift to less harmful cleaning solvents.
本発明の洗浄液は、特に、金属を鋳造法で加工する際に用いる鋳型の製造時に使用した金型の表面を効果的に洗浄することができる。さらに、本発明の洗浄液は、樹脂と鋳物砂の硬化物からなる鋳型を金型から離型した後に、金型表面に付着した鋳物砂と樹脂を除去すると同時に、金型表面の発錆を抑制することができる。 In particular, the cleaning liquid of the present invention can effectively clean the surface of a mold used at the time of producing a mold used when a metal is processed by a casting method. Further, the cleaning liquid of the present invention removes the molding sand and resin adhering to the mold surface after releasing the mold made of a cured resin and molding sand from the mold, and at the same time, rusts the mold surface. Can be suppressed.
脂肪酸グリセリルのモノエステル、ジエステル、およびトリエステルの重量混合比としては、好ましくは、モノエステル:ジエステル:トリエステル=30〜70:20〜60:1〜30、より好ましくは、モノエステル:ジエステル:トリエステル=40〜60:30〜50:2〜20である。防錆効果の検討から、この3成分の混合比の内、ひとつでも0の場合は、防錆効果が低下する。 The weight mixing ratio of monoester, diester, and triester of fatty acid glyceryl is preferably monoester: diester: triester = 30 to 70:20 to 60: 1 to 30, more preferably monoester: diester: Triester = 40-60: 30-50: 2-20. From the examination of the rust prevention effect, if any one of the mixing ratios of the three components is 0, the rust prevention effect is lowered.
アミン類は、例えば、ベンジルアミン、2、4−ジメトキシベンジルアミン、4−tert−ブチルベンジルアミン、2、3−ジメチルベンジルアミン、2−メトキシベンジルアミン、4−メトキシベンジルアミン、4−ヒドロキシベンジルアミン等が挙げられるが、洗浄液の洗浄力を向上させ、低有害性かつ、工業的に入手しやすいという観点から、好ましくはベンジルアミンである。 Examples of amines include benzylamine, 2,4-dimethoxybenzylamine, 4-tert-butylbenzylamine, 2,3-dimethylbenzylamine , 2-methoxybenzylamine, 4-methoxybenzylamine, 4-hydroxybenzylamine. Among them, benzylamine is preferable from the viewpoint of improving the detergency of the cleaning liquid, low toxicity, and industrial availability.
