Abstract
Description
90mil(2.29mm)のポリウレタン発泡体層(Rubberlite,Inc.,Huntington,West Virginia,USAから商品名「HYPUR−CEL S0601」として入手可能)を、3g/ft2(32.29g/m2)乾燥重量の「H−2679」でコーティングした。次に、3.0mil(76.2μm)のポリエステルフィルム(Mitsubishi Polyester Film,Inc.,Greer,South Carolina,USAから商品名「HOSTAPHAN 2262」として購入)を、D−6019を用いて発泡体の反対側に積層した。52g/m2のけば立てたナイロンループ布地(Sitip SpA,Cene,Italyから商品名「ART.TROPICAL L」として入手可能)を、SG−1582を用いてポリエステルフィルムの露出した面に積層した。
樹脂プレミックスを次のように作製した。403.0グラムのSR339、607.0グラムのSR351、及び96.0グラムのS24000を共に混合し、60℃に加熱し、S24000が溶解するまで、約1時間、断続的に攪拌した。次に、溶液を21℃に冷却し、60.0グラムのA−174と33.6グラムのTPO−Lを添加し、均質に分散するまで樹脂プレミックスを攪拌した。
高速剪断ミキサーを用いて、21℃で15分間、958グラムのGC2500を600グラムの樹脂プレミックスに均質に分散し、その後、スラリーを60℃に加熱し、2時間維持し、次いで21℃に冷却し戻した。
GC2500を等重量のGC4000で置き換え、加えて19.7グラムのブルー顔料を600グラムの樹脂プレミックスに均質に分散して、AS−1に関して上述される一般手順に従い研磨材スラリーを調製した。
MRT−1
有用なツールの詳細な製作の実施例は、米国特許第US−A−5152917号(Pieperら)、同第US−A−5435816号(Spurgeonら)、同第US−A−5672097号(Hoopmanら)、同第US−A−5946991号(Hoopmanら)、同第US−A−5975987号(Hoopmanら)、及び同第US−6129540号(Hoopmanら)に見出すことができる。
以下により詳細に記載されるように、高精細複製研磨パターンが図7〜10に示されるパターンに対応した、概ね上述のMRT−1に関して記載される製作手順を繰り返した。
研磨材スラリーAS−1は、ナイフコーティングにより、約5.5mg/cm2のコーティング重量で高精細複製ポリプロピレンツールMRT−1に適用された。次に、スラリー充填ポリプロピレンツールは、発泡体のラテックスコーティングされた表面上のニップロールと接触させられ、600W/インチ(236W/cm)、ライン速度70フィート/分(21.3m/分)、及びニップ圧60psi(413.7kPa)で、Fusion Systems Inc.,Gaithersburg,Maryland,USAの「D」型バルブを有するUVプロセッサを用いてUV硬化された。その後ツールを除去して、寸法120μm×55μm及び高さ55μmの基部を有する高精細複製砥粒をポリウレタン発泡体上に露出させた。
研磨材スラリーAS−1を研磨材スラリーAS−2で置き換え、ライン速度を40フィート/分(12.2m/分)に減少させ、概ね実施例1に記載される手順を繰り返した。
高精細複製ツールMRT−1をMRT−2で置き換えて、概ね実施例1に記載される手順を繰り返した。
研磨材スラリーAS−1を研磨材スラリーAS−2で置き換えて、概ね比較Aに記載される手順を繰り返した。
特に明記しない限り、以下の評価においてそれらの商品名で特定される全てのツール及び材料は、3M Company,St Paul,Minnesota,USAから購入した。
研磨性能試験は、ACT Laboratories,Inc.,Hillsdale,Michigan,USAから購入した、18インチ×24インチ(45.7cm×61cm)の黒色塗装クリアコート冷間圧延鋼試験パネル(部品番号「55875」)で実施された。直径6インチ(15.2mm)のサンディングディスク(商品名「260L P1200 HOOKIT FINISHING FILM」)を同じサイズの「HOOKIT SOFT INTERFACE PAD、部品番号05777」に取り付け、同時にこれを「HOOKIT BACKUP PAD、部品番号「05551」に取り付けた。次に、パッドアセンブリを、モデル番号「28500」ランダムオービタルサンダーに固定した。ライン圧40psi(275.8kPa)及びダウンフォース約10lb(4.54kg)を用いて、パネルにわたってサンダーを水平に7回、次に垂直に9回掃引してパネルを事前にこすり、約50%が掃引間で重複した。こすったパネルをマイクロファイバ布で拭き、秤量した。260Lの仕上げフィルムをサンプルディスクで置き換え、パネルに軽く水を噴霧し、50%が重複する水平及び垂直掃引で1分間サンディングを繰り返した。次いで、パネルを乾拭きし、切断量を測定するために再度秤量し、Taylor Hobson,Inc.,Leicester,Englandのモデル「SURTRONIC 3+PROFILOMETER」を用いて、平均表面仕上げ(Rz)を5か所で測定した。その後、サンディングプロセスを3回繰り返し、累積切断及び平均仕上げを表1に列挙した。
黒色塗装冷間圧延鋼試験パネルを切断及び仕上げ試験1に記載されるようにこすり、その後、パネルを秤量し、平均仕上げを5か所で測定した。両面接着テープを使用して、2.25×9.00インチ(5.72×22.86cm)試験サンプルを類似するサイズの8lb(3.63Kg)サンディングブロックに取り付けた。次に、こすったパネルを水に浸し、往復運動を適用することにより試験サンプルを手でサンディングした(1回の往復運動は1サイクルに等しい)。10サイクル後、試験パネルを乾拭きし、平均表面仕上げを3か所で測定した。次に、プロセスを更に40サイクル繰り返し、毎10サイクル後にパネルを再度濡らした。パネルを乾拭きし、再度秤量し、平均表面仕上げを再度3か所で測定した。結果を表2に示す。
