Description
特に明記しない限り、実施例及び本明細書のその他の箇所における全ての部、百分率、比などは、重量によるものである。特に明記しない限り、他の全ての試薬は、ミズーリ州St.LouisのSigma−Aldrich Companyなどの化学業者から入手したか、又は入手可能であり、あるいは既知の方法で合成することができる。
メイクコート接着剤組成物は、4リットルのプラスチック容器に1521グラムのPF1,1236グラムのFIL2を充填し、機械的に混合し、次いで水で総重量3キログラムに希釈することによって、調製した。
BACK1に、ロールコーティング法を用いて、1平方メートル当たり180.0グラム(g/m2)のコーティング重量でメイクコート接着剤組成物1をコーティングした。次に、研磨粒子MIN1及びMIN2を、米国特許第8,511,577号(Morenら)に開示された方法に従って、静電堆積法を使用して1:1の重量比で、メイク樹脂被覆バッキングに加えた。MIN1及びMIN2の双方の総コーティング重量は、549.3g/m2であった。次いで、研磨コーティングロールをオーブンに65.6℃で15分間、続いて98.9℃で90分間配置した。次いで、69.9部のPF1、7.0部のFIL3、13.3部のWAx1、1.4部のRIO、及び8.4部の水のサイズコートを、481.3g/m2のコーティング重量でメイク樹脂及び鉱物コーティングされたバッキングに加えた。次いで、コーティングされたバッキングロールを175°F(79.4℃)のオーブンに20分間、続いて210°F(98.9℃)で65分間配置した。次いで、バッキング材料をロールに巻き、102.8℃で12時間、強制空気硬化用オーブンに配置した。
BACK1に、ロールコーティング法を用いて、180.0g/m2のコーティング重量でメイクコート接着剤組成物1をコーティングした。次いで、実施例1に記載の静電堆積法を用いて、研磨粒子MIN1及びMIN2をメイク樹脂被覆バッキングに1:1の重量比で加えた。MIN1及びMIN2の双方の総コーティング重量は、549.3g/m2であった。次いで、研磨コーティングロールをオーブンに65.6℃で15分間、続いて98.9℃で90分間配置した。次いで、52.1部のPF1、35.4部のFIL3、5.2部のWAx1、1.0部のRIO、及び6.3部の水、のサイズコートを、481.3g/m2のコーティング重量で、メイク樹脂と鉱物コーティングされたバッキングとに加えた。次いで、コーティングされたバッキングロールをオーブンに175°F(79.4℃)で20分間、続いて210°F(98.9℃)で65分間配置した。次いで、バッキング材料をロールに巻き、102.8℃で12時間、強制空気硬化用オーブンに配置した。

BACK1に、ロールコーティング法を用いて、180.0g/m2のコーティング重量でメイクコート接着剤組成物1をコーティングした。次いで、実施例1に記載のように静電堆積法を用いて、メイク樹脂被覆バッキングに1:1重量比で、研磨粒子MIN1及びMIN2を加えた。MIN1及びMIN2の双方の総コーティング重量は、549.3g/m2であった。次いで、研磨コーティングロールをオーブンに65.6℃で15分間、続いて98.9℃で90分間配置した。次いで、52.4部のPF1、40.3部のFIL3、1.0部のRIO、及び6.3部の水、のサイズコートを、メイク樹脂と鉱物コーティングされたバッキングとに、481.3g/m2のコーティング重量で加えた。次いで、コーティングされたバッキングロールをオーブンに175°F(79.4℃)で20分間、続いて210°F(98.9℃)で65分間配置した。次いで、バッキング材料をロールに巻き、102.8℃で12時間、強制空気硬化用オーブンに配置した。
比較例Bは、3M Company(Saint Paul、Minnesota)から商品名「984F36+CUBITRON(商標)II METALWORKING BELT」で入手した被覆ベルトであった。
研磨試験は、実施例1〜3、並びに比較例A及びBから得られた被覆研磨材サンプルから変換された10.16センチメートル(cm)の×91.44cmのベルト上で実施した。加工物は、研磨される表面が1.9cm×1.9cmで測定された6061アルミニウムバーであった。直径20.3cmの70デュロメータゴム、1:1ランド対溝比、鋸歯状接触ホイールを使用した。ベルトを毎分2750回転で走行させた。加工物を4.4kgの法線力でベルトの中心部に印加した。この試験は、15秒間の研磨後の加工物の重量減少を測定することからなるものであった。次に加工物を冷却し、再び試験した。試験は、25回のサイクル後に完了した。グラムによる総切削量は、25サイクル後の加工物の総重量減少として定義した。結果を表2に示す。
