【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。
