を洗浄し除去するために利用される。This cleaning agent is used, for example, when painting a urethane resin molded product, to clean and remove mold release agents such as zinc stearate that adhere to the molded product during molding.
〔従来の技術］
自動車のバンパーのようなウレタン樹脂成形品を塗装す

がある。この離型剤は、通常、ステアリン酸亜鉛が用い
られる。このステアリン酸亜鉛の除去が不十分であると
、塗装の際に「ハジキ」や「ハガレ」が生じる。[Prior Art] When painting a urethane resin molded product such as an automobile bumper, it is necessary to remove the mold release agent remaining on the surface of the molded product. As this mold release agent, zinc stearate is usually used. If the removal of this zinc stearate is insufficient, "repelling" or "peeling" will occur during painting.
従来、これらステアリン酸亜鉛の除去は、次のように行
われていた。Conventionally, removal of these zinc stearates has been carried out as follows.
その一つは、パワーウォシュによる洗浄である。゛この

リン酸亜鉛を除去している。One of them is power washing.゛This power wash uses a phosphoric acid-based aqueous solution cleaning agent such as sodium hydrogen phosphate, and sprays the cleaning agent onto the molded product to remove zinc stearate.
これに対し、別の方法として、トリクロルエタンによる
蒸気洗浄がある（「溶剤ハンドブック」２５４〜２５５
頁、昭和４７年７月２０日産業図書発行）。On the other hand, another method is steam cleaning with trichloroethane ("Solvent Handbook" 254-255).
Page, published by Sangyo Tosho on July 20, 1971).
上述のパワーウォシュは洗浄効果が大きいが、水溶液を
使用するために、リンスや、乾燥時間が長く、吹き付け
るための広いスペースを確保する必要がある。また、吹
き付けのための設備が大掛かりになるという問題がある
。The above-mentioned power wash has a great cleaning effect, but since it uses an aqueous solution, it requires long rinsing and drying times, and it is necessary to secure a large space for spraying. Another problem is that the equipment for spraying is large-scale.
上述の蒸気洗浄は、乾燥時間をそれ程要せず、また、吹
き付けのための設備が小さく済むが、溶解パラメータが
ステアリン酸の溶解パラメータと異なるため、洗浄効果
が十分でない、従来において、溶解パラメータを近づけ
ることにより溶解度を高める例は見られない。The above-mentioned steam cleaning does not require much drying time and requires small equipment for spraying, but the solubility parameter is different from that of stearic acid, so the cleaning effect is not sufficient. There are no examples of increasing solubility by bringing them closer together.
また、溶解パラメータが近い洗浄剤としてトリクレンが
あるが、取扱いに注意を要するので、設備が大掛かりに
なる問題が残る。Additionally, Triclean is a cleaning agent with similar solubility parameters, but it requires care in handling, which leaves the problem of requiring large-scale equipment.
したがって、本発明の目的は、洗浄効果が大きく、簡素
な設備で対応することが可能なステアリン酸亜鉛の洗浄
剤を提供することにある。Therefore, an object of the present invention is to provide a zinc stearate cleaning agent that has a large cleaning effect and can be handled with simple equipment.
そこで、本発明のステアリン酸亜鉛の洗浄剤は、ブチレ
ンオキサイド、ジオキサン、−二トロメタン、イソプロ
パノールを所定割合で添加してトリクロルエタンの洗浄
効果を改善したことを特徴とする。Therefore, the zinc stearate cleaning agent of the present invention is characterized by adding butylene oxide, dioxane, -nitromethane, and isopropanol in predetermined proportions to improve the cleaning effect of trichloroethane.
具体的には、本発明の構成は次の通りである。Specifically, the configuration of the present invention is as follows.
本発明のステアリン酸亜鉛の蒸気洗浄用洗浄剤は、容積

2-0.8% butylene oxide, 0.5-4.5%
dioxane, 0.2-3% nitromethane, 1-2%
of isopropanol.
上述の本発明のステアリン酸亜鉛の蒸気洗浄用洗浄剤に
よれば、従来のトリクロルエタンを主成分とする洗浄剤
に対して、イソプロパノールを１〜２％添加することに
より、洗浄剤の溶解パラメータをステアリン酸亜鉛に近
づけ、溶解度を高まった。イソプロパノールの添加量が
１％未満の場合は、溶解度が低く、また、２％を越える
場合は、印加性が高まるので、１〜２％の範囲とした。According to the above-mentioned zinc stearate steam cleaning agent of the present invention, the solubility parameter of the cleaning agent can be improved by adding 1 to 2% isopropanol to the conventional cleaning agent whose main component is trichloroethane. Close to zinc stearate and has increased solubility. If the amount of isopropanol added is less than 1%, the solubility is low, and if it exceeds 2%, the applicability increases, so it was set in the range of 1 to 2%.
また、イソプロパノールの添加は、ステアリン酸亜鉛と
水和して親水性を高め、その点からもステアリン酸亜鉛
の溶解度を高めることができると考えられる。It is also believed that the addition of isopropanol hydrates zinc stearate and increases its hydrophilicity, and from this point of view as well, it can increase the solubility of zinc stearate.
また、トリクロルエタンは、その洗浄効果が有効な範囲
として９２〜９３％が用いられる。Further, trichloroethane is used in a range of 92 to 93%, which is effective for its cleaning effect.
また、ブチレンオキサイドは、塩素の発生による金属腐
食を防止するために用いられ、その効果が有効な範囲と
して０．２〜０．８％が用いられる。Further, butylene oxide is used to prevent metal corrosion due to the generation of chlorine, and the range in which the effect is effective is 0.2 to 0.8%.
