【産業上の利用分野】
この発明はコンパウンドにコーンコブ又は籾殻粉の何れか一方又は両方を付与し、又はコーンコブ又は籾殻粉の何れか一方又は両方を添加して研磨することにより、良好な光沢仕上げを得ることを目的としたバレル研磨用コンパウンド及びバレル研磨法に関する。
【0002】
【従来の技術】
従来バレル研磨用コンパウンドは、潤滑作用、洗浄作用、発泡作用、防錆作用、脱脂作用等があり、研磨後の工作物の表面状態をより良好にする為、必要とされ、適宜用いられていた。
【0003】
【発明により解決すべき課題】
然し乍ら従来使用されているコンパウンドでは仕上げ面の光沢等が不十分になる問題点があった。特にステンレス系の工作物は、研磨後の表面に黒いスマットが付着する問題点があった。
【0004】
またコンパウンドに木粉を添加することも試みられているが、満足すべき結果が得られていない。
【0005】
【課題を解決するための手段】
然るにこの発明はコンパウンドにコーンコブ(とうもろこしの芯を粉砕した粉体)又は籾殻粉の何れか一方又は両方を添加し、又は研摩槽内へコーンコブ又は籾殻粉の何れか一方又は両方をコンパウンドとは別に装入して研磨することにより、前記従来の問題点を解決したのである。
【0006】
即ちこの発明はバレル研磨に用いる界面活性剤を主成分とするコンパウンドへ適量のコーンコブ又は籾殻粉の何れか一方又は両方を添加したことを特徴とするバレル研磨用コンパウンドである。また他の発明はバレル研磨に用いる界面活性剤を主成分とするコンパウンドへ適量のコーンコブ又は籾殻粉の何れか一方又は両方及び木粉を添加したことを特徴とするバレル研磨用コンパウンドであり、コンパウンドを界面活性剤と、防錆剤、キレート剤又は洗浄助剤の1種又は2種以上の混合物としたものである。次に方法の発明はコーンコブ又は籾殻粉の何れか一方又は両方の添加量はバレル研磨用コンパウンド全量に対し5重量%以上が適当である。5%未満では良好な光沢仕上ができない。コーンコブ又は籾殻粉の何れか一方又は両方のサイズは#60以上の細粒が適当である。#60未満の粗粒では光沢向上の効果が少ない。更に他の発明は研磨槽内へ工作物、研磨材、コーンコブ又は籾殻粉の何れか一方又は両方のコンパウンド、及び水を装入し、研磨槽に回転運動、遊星旋回運動又は振動等の研磨に必要な運動を与えて研磨することを特徴としたバレル研磨法であり、コーンコブ又は籾殻粉の何れか一方又は両方は単独で装入し、又はコンパウンドに添加して装入することを特徴としたものである。
【0007】
前記における界面活性剤としては、脂肪酸塩(例えばラウリン酸ナトリウム、パルミチン酸ナトリウム、ステアリン酸ナトリウム、オレイン酸ナトリウム等)、スルフォン化物(例えばアルキルアリル・スルフォン酸ナトリウム等)、アルコール硫酸化物(例えばラウリルアルコール硫酸化エステルナトリウム等)、等の陰イオン界面活性剤及びポリエチレン・グライコール・モノラウレート、ポリオキシエチレン・オレイルエーテル、ポリオキシエチレンアルキルアリルエーテル、ポリオキシエチレン・ソルビタンモノラウレート、アルキロールアマイド(例えばヤシ油脂肪酸ジエタノールアミド等)等の非イオン界面活性剤等を単独又は混合して用いる。前記界面活性剤は、工作物に洗浄作用、光沢作用及び潤滑作用を及ぼす目的で用いる。
【0008】
この発明で用いる防錆剤としては、例えば亜硝酸塩、ホウ酸塩、リン酸塩、芳香族カルボン酸塩、等を単独又は混合して用いる。この発明に用いるキレート剤としては、例えばオキシカルボン酸(例えばクエン酸、リンゴ酸、酒石酸、グリコール酸、グルコン酸等)又はその塩、アミノポリカルボン酸、(例えばエチレンジアミン四酢酸、ジエチレントリアミン五酢酸、ニトリロ三酢酸、グリコールエーテルジアミン四酢酸等)又はその塩等を単独又は混合して用いる。前記キレート剤は硬水軟化作用を有する。
【0009】
またこの発明に用いる洗浄助剤としては、例えば粉末繊維素(木粉等)、カルボキシメチルセルロース等を用いる。
【0010】
この発明によれば、バレル研磨に際し、コンパウンド内に又は研磨中に大きさ#60以上で、コンパウンドに対し、5重量%以上のコーンコブを添加したので、工作物表面に付着する黒いスマットは除去され、より白ぽい良好な光沢仕上を得る事が出来る。これはコーンコブが木粉に比べて、より緻密な多孔性の繊維質である為、スマット等のよごれを吸着又は拭き取る効果が高い為と考えられる。
【0011】
また木粉はセルロース繊維長が長く、繊維組織が多いが、コーンコブ粉及び籾殻粉では繊維長が短く、結晶状態が丸く、繊維組織が殆んど見られない。#120の木粉の嵩比重は0.24Kg/ lに対し、#120のコーンコブ粉では0.44Kg/ l、籾殻粉では0.57Kg/ lと、約2倍の嵩比重を有し、嵩比重の増大に伴い、コンパウンドの生産性が向上すると共に、包装費、収納スペース及び輸送費の節減ができる効果がある。更に、木粉を使用したコンパウンドでは工作物の微細部に長繊維が閉塞する問題点があつたが、コーンコブ粉及び籾殻微粉の場合は殆んど解決した。

[Industrial applications]
This invention is intended to obtain a good gloss finish by imparting one or both of corn cob and rice husk powder to the compound, or by adding and polishing one or both of corn cob and rice husk powder. The present invention relates to a compound for barrel polishing and a barrel polishing method.
[0002]
[Prior art]
Conventionally, the compound for barrel polishing has a lubricating action, a cleaning action, a foaming action, a rust-preventing action, a degreasing action, etc., and is required and used appropriately in order to improve the surface condition of the workpiece after polishing. .
[0003]
Problems to be solved by the invention
However, there has been a problem in that conventionally used compounds have insufficient gloss and the like on the finished surface. Particularly, a stainless steel workpiece has a problem that black smut adheres to the polished surface.
[0004]
Attempts have also been made to add wood flour to the compound, but satisfactory results have not been obtained.
[0005]
[Means for Solving the Problems]
However, the present invention adds one or both of corn cob (powder of corn core) and rice husk powder to the compound, or puts one or both of corn cob and rice husk powder into the polishing tank separately from the compound. The conventional problem was solved by loading and polishing.
[0006]
That is, the present invention is a compound for barrel polishing characterized in that an appropriate amount of either or both corn cob and rice husk powder is added to a compound mainly containing a surfactant used for barrel polishing. Another invention is a compound for barrel polishing characterized in that a suitable amount of either or both corn cob and rice husk powder and wood powder are added to a compound mainly containing a surfactant used for barrel polishing. Is a mixture of one or more of a surfactant and a rust inhibitor, a chelating agent or a cleaning aid. Next, in the invention of the method, the addition amount of one or both of corn cob and rice husk powder is suitably 5% by weight or more based on the whole amount of the barrel polishing compound. If it is less than 5%, good gloss finish cannot be obtained. The size of one or both of corn cob and rice husk flour is suitably a fine grain of # 60 or more. With coarse particles of less than # 60, the effect of improving gloss is small. Still another invention is a method in which a workpiece, an abrasive, a compound of corn cob or rice husk powder, or both, and water are charged into a polishing tank, and the polishing tank is used for polishing such as rotational motion, planetary swirling motion or vibration. A barrel polishing method characterized by giving a necessary movement and polishing, characterized in that either one or both of corn cob and rice husk powder are charged alone, or added to a compound and charged. Things.
[0007]
Examples of the surfactant include fatty acid salts (eg, sodium laurate, sodium palmitate, sodium stearate, sodium oleate, etc.), sulfonated compounds (eg, sodium alkyl allyl sulfonate), alcohol sulfates (eg, lauryl alcohol) Anionic surfactants such as sodium sulfated ester), polyethylene glycol monolaurate, polyoxyethylene oleyl ether, polyoxyethylene alkyl allyl ether, polyoxyethylene sorbitan monolaurate, alkylol amide A nonionic surfactant such as coconut oil fatty acid diethanolamide or the like is used alone or in combination. The surfactant is used for the purpose of exerting a cleaning action, a gloss action and a lubrication action on a workpiece.
[0008]
As the rust preventive used in the present invention, for example, nitrite, borate, phosphate, aromatic carboxylate and the like are used alone or in combination. Examples of the chelating agent used in the present invention include oxycarboxylic acids (eg, citric acid, malic acid, tartaric acid, glycolic acid, gluconic acid, etc.) or salts thereof, aminopolycarboxylic acids (eg, ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, nitrilo) Triacetic acid, glycol ether diamine tetraacetic acid, etc.) or a salt thereof, alone or in combination. The chelating agent has a water softening action.
[0009]
As the cleaning aid used in the present invention, for example, powdered cellulose (eg, wood flour), carboxymethyl cellulose, or the like is used.
[0010]
According to the invention, when the barrel polishing, a size # 60 or more or during polishing in the compound, relative to compound, since the addition of 5 wt% or more Konko blanking, black smut adhering to the workpiece surface is removed is, it is possible to obtain a finish more white Poi good gloss. This is Konko blanking is compared with the wood powder, because it is more dense porous fibrous believed because of high adsorption or wipe effects stains such smut.
[0011]
Wood flour has a long cellulose fiber length and a large fiber texture, whereas corn cob flour and rice husk flour have a short fiber length, a round crystalline state, and almost no fiber texture. # 120 wood flour has a bulk specific gravity of 0.24 Kg / l, # 120 corncob flour has a bulk specific gravity of 0.44 kg / l, and rice husk flour has a bulk specific gravity of 0.57 kg / l. As the specific gravity increases, the productivity of the compound improves, and there is an effect that the packaging cost, the storage space, and the transportation cost can be reduced. Further, in the compound using wood flour, there was a problem that the long fiber was clogged in the fine part of the workpiece, but in the case of corn cob flour and fine rice husk, it was almost solved.
[0012]
Embodiment 1
A centrifugal flow barrel polishing machine HS-2000 manufactured by Tipton Co., Ltd. was charged with the polishing stone HCS-4 for the same gloss finish, the powder compound for the same gloss finish, and water, and a test piece was subjected to a gloss test. The conditions are as shown in Tables 1 and 2.

[0026]
[Table 8]
Figure 0003590906
[0027]
Compared with the conventional compound (addition of 30% by weight of wood flour), the compound of VII (addition of 30% by weight of rice husk) of the present invention has improved glossiness in both SUS and Brass, and the polishing amount and surface roughness are improved. It was almost equivalent. Table 9 shows the test results.
