Abstract

<P>PROBLEM TO BE SOLVED: To solve many problems such that poor lubricating property occurs when a conventional lubricant such as a mineral oil is used for antifriction between materials or that post-treatment such as oil treatment is difficult to carry out or is not eco-friendly, for example. <P>SOLUTION: In the case of friction of the materials with each other, a lubricant is used for the surfaces of the materials to reduce friction. The surfaces of the materials are coated with, instead of the conventional lubricant, a hon-mirin solution (Japanese sweet rice wine for cooking produced using glutinous rice, malted rice, and distilled spirit) that exerts lubricating functions via partial solidification of the hon-mirin solution upon friction of the materials and coated with a hon-mirin solution containing honey or sugar or containing wheat flour as a lubricant. With the use of such eco-friendly solutions having good lubricating property, the work can be done more easily than conventional cases. <P>COPYRIGHT: (C)2009,JPO&amp;INPIT

Description

本発明は、金属あるいは非金属の材料と材料とが互いに擦り合うような際に、擦り合う材料の表面に従来のような鉱物油系等の潤滑剤を使用するのではなくて、炭水化物やアルコールを含む本みりんを主成分とする液体、いわゆるみりん系の液体を、互いに擦り合う材料の表面に塗布し、材料同士が擦り合う際に、液体が一部固形化して潤滑機能を発揮することのある潤滑剤に関するものである。そして、この潤滑剤適用の一つとして、金属あ るいは非金属材料の塑性加工時に適用できる潤滑剤に関するものである。In the present invention, when a metal or non-metal material and a material rub against each other, a conventional mineral oil-based lubricant is not used on the surface of the rubbed material. liquid composed mainly of mirin containing, liquid so-called mirin system, applied to the surface of the material rub against each other, when the material between the rubbing, Kotono liquid exerts in part solidified lubricating function It relates to a certain lubricant. Then, as one of the lubricant application, the metal Oh Rui relates lubricant which can be applied at the time of plastic working non-metallic materials.

従来、金属材料などの材料同士が互いに擦り合うような場合、両材料の間には、潤滑剤がないと良好な作業ができないなど具合が悪い場合が多い。このような場合、従来の作業工程では、材料表面に主に鉱物油系の潤滑剤を塗布して減摩し作業が行われている。  Conventionally, when materials such as metal materials rub against each other, there are many cases where the two materials do not work well without a lubricant between them. In such a case, in the conventional work process, a mineral oil-based lubricant is mainly applied to the material surface to reduce the friction.

従来使用されている潤滑剤は、鉱物油系が主なもので、油そのものの取り扱いにくさ、あるいは使用後の後処理など、油を使用して行う作業においては多くの課題を含んでいる。また、これらに使用される潤滑剤は、使用後の後処理が必要であり、取り除くか、あるいは作業終了後も製品にそのまま付着したままになる場合も多い。いずれの場合でも、これらの潤滑剤が環境に害を与えるものであってはならない。  Conventionally used lubricants are mainly mineral oils, and there are many problems in operations performed using oil such as difficulty in handling the oil itself or post-treatment after use. In addition, the lubricant used for these requires post-treatment after use, and is often removed or remains attached to the product even after the work is completed. In any case, these lubricants must not harm the environment.

本発明は、材料と材料とが互いに擦り合う場合について、上記問題点を解決すべく種々検討した結果、従来の潤滑油に代わって、液体を材料表面に塗布し材料同士が互いに擦り合う際に、その液体が一部固形化して潤滑機能を発揮することのある性質をもち、その液体に炭水化物やアルコールを主成分とする本みりん液、あるいはこれに蜂蜜や砂糖の糖分を含ませた液、または小麦粉を含ませた液を用い、これを互いに擦り合う材料の表面に塗布して、潤滑機能を発揮させるものである。また本発明潤滑剤は、塗布性もよく、また使用後は材料表面から水などで容易に洗い落とすことができ、しかも後処理した液も環境に対して害を与えるものではない。本発明潤滑剤の本みりん、蜂蜜および砂糖、そして小麦粉などの原料は食品の主原料でもあるので、環境に対してやさしく、また主に植物を通して得るものであるので、これらは育成すれば得ることのできる半永久的資源であり、本発明潤滑剤は、環境、資源の両面からの対策にもなり得るものである。In the present invention, as a result of various studies to solve the above-described problems when the materials rub against each other, the liquid is applied to the material surface instead of the conventional lubricating oil, and the materials rub against each other. This liquid has the property of partially solidifying and exerting a lubricating function, and the liquid is a main mirin liquid mainly composed of carbohydrates or alcohol, or a liquid containing honey or sugar sugar. Alternatively, a liquid containing wheat flour is used and applied to the surfaces of materials that rub against each other to exert a lubricating function. The lubricant of the present invention has good coating properties and can be easily washed off from the surface of the material with water after use, and the post-treated liquid does not harm the environment. Since the raw materials such as mirin, honey and sugar, and flour of the lubricant of the present invention are also main ingredients of food, they are environmentally friendly and are mainly obtained through plants. The lubricant of the present invention can be a countermeasure from both environmental and resource aspects.

本発明において、互いに擦り合う材料とは、鉄鋼系、ステンレス系、チタン系、アルミ系、銅系など金属あるいは非金属材料などのことであり、その材料の形状については特定しない。本発明潤滑剤は、液体状のもので、これを材料表面に塗布し材料同士が互いに擦り合う際に、その液体が一部固形化して潤滑機能を発揮することのある性質をもち、その液体は本みりんの液で、またこれに蜂蜜あるいは砂糖の糖分を含む液としたもの、あるいは小麦粉を含む液にすることにより、さらに潤滑性能が向上するもので、これらを互いに擦り合う材料の表面に塗布して使用するものである。本みりん、蜂蜜および砂糖、あるいは小麦粉などは通常食品に用いられているものでよい。本みりんに含ませる蜂蜜あるいは砂糖、あるいは小麦粉の含有量は、各々4質量%およびそれ以上、40質量%およびそれ以下である。なお本発明における%表示は、すべて質量%である。塗布後の付着性も良好である。この潤滑剤の適用の一つとしては、金属あるいは非金属材料の塑性加工時の潤滑剤に使用するのが適している。
