の関係を満たすようにすることで、汚染防止剤組成物をドライパート部位に付与することにより、高分子ポリシロキサン化合物がピッチの付着を防止させる効果を発揮し、低分子ポリシロキサン化合物がピッチを分散させる効果を発揮する。これにより、ドライパート部位へのピッチの付着を十分に防止できる。なお、本願明細書において、ピッチとは、抄紙工程において生じる粘着性の固体や紙粉の集合体等が含まれる。
したがって、上記汚染防止剤組成物によれば、これらの作用により、ドライパート部位へのピッチの付着を十分に防止できる。
上記低分子ポリシロキサン化合物において、メチル基と変性基とは、低分子ポリシロキサン化合物1分子中に混在していてもよい。また、置換基R1がすべてメチル基の低分子ポリシロキサン化合物と、置換基R1がすべて変性基の低分子ポリシロキサン化合物とが混在したものであってもよい。
これらの中でも、低分子ポリシロキサン化合物における変性基は、アミノ変性基であることが好ましく、下記式(3)で表される変性基又は下記式(4)で表される変性基であることがより好ましく、下記式(3)で表される変性基であることが更に好ましい。この場合、理由は定かではないが、アミノアルキレン基がピッチを分散させる効果を発揮するため、ドライパート部位へのピッチの付着が確実に防止される。
これらの中でも、上記置換基R3及び置換基R4はそれぞれ独立して、エチレン基又はプロピレン基であることが好ましく、置換基R3がプロピレン基であり、置換基R4がエチレン基であることがより好ましい。
これらの中でも、上記置換基R5は、プロピレン基であることが好ましい。
変性基の個数が0.1個未満であると、ピッチを分散する効果が得られず、変性基の個数が3.0個を超えると、イオン性が高くなり、汚染防止剤組成物中の水分が蒸発する過程でゲル化を起こしやすく、返ってピッチを付着させてしまう恐れがある。
ポリシロキサン単位の繰り返し数mが20未満であると、揮発性が高くなる欠点があり、ポリシロキサン単位の繰り返し数mが200を超えると、ピッチの分散性が低下する。
動粘度が10mm2/s未満であると、動粘度が上記範囲内にある場合と比較して、付与した低分子ポリシロキサン化合物がドライパート部位に留まらなくなる欠点があり、動粘度が300mm2/sを超えると、動粘度が上記範囲内にある場合と比較して、ピッチを十分に分散できなくなる場合がある。
上記高分子ポリシロキサン化合物において、メチル基と変性基とは、高分子ポリシロキサン化合物1分子中に混在していてもよい。また、置換基R2がすべてメチル基の高分子ポリシロキサン化合物と、置換基R2がすべて変性基の高分子ポリシロキサン化合物とが混在したものであってもよい。
これらの中でも、高分子ポリシロキサン化合物における変性基は、アミノ変性基であることが好ましく、下記式(5)で表される置換基又は下記式(6)で表される置換基であることがより好ましい。この場合、理由は定かではないが、同様な変性基を有する低分子ポリシロキサン化合物との相溶性が向上し、且つ高分子ポリシロキサン化合物及び低分子ポリシロキサン化合物のドライパート部位への皮膜の定着性が向上する。
これらの中でも、上記置換基R6及び置換基R7はそれぞれ独立して、エチレン基又はプロピレン基であることが好ましく、置換基R6がプロピレン基であり、置換基R7がエチレン基であることがより好ましい。
これらの中でも、上記置換基R8は、プロピレン基であることが好ましい。
変性基の個数が1.0個未満であると、皮膜の定着性が不十分となり、変性基の個数が6.0個を超えると、べとつきが大きくなり、かえってピッチが付着しやすくなる欠点がある。
ポリシロキサン単位の繰り返し数nが1430以上であると、粘度が高い高分子ポリシロキサン化合物が、ドライパート部位表面に粘着性を帯びて付着するので、かえってピッチが付着しやすくなる欠点がある。なお、本発明の汚染防止剤組成物は、高分子ポリシロキサン化合物におけるポリシロキサン単位の繰り返し数nが1430未満の整数である場合、汚染防止剤組成物の流動性が優れるため、取り扱い易い。
動粘度が40mm2/s未満であると、動粘度が上記範囲内にある場合と比較して、ドライパート部位に、高分子ポリシロキサン化合物の皮膜を形成しにくくなる欠点があり、動粘度が90000mm2/sを超えると、動粘度が上記範囲内にある場合と比較して、汚染防止剤組成物中の水分が蒸発する過程でガム化が生じやすく、ベト付くので、紙を汚染してしまうという欠点がある。

の関係を満たす。すなわち、高分子ポリシロキサン化合物におけるポリシロキサン単位の繰り返し数nは、低分子ポリシロキサン化合物におけるポリシロキサン単位の繰り返し数mの2倍以上とする。
乳化剤を含むことにより、低分子ポリシロキサン化合物及び高分子ポリシロキサン化合物の乳化安定性が向上する。
これらの中でも、乳化剤は、ノニオン界面活性剤であることが好ましく、特に、ポリエチレンデシルエーテル、ポリエチレンセチルエーテル又はポリエチレンステアリルエーテルであることがより好ましい。
ちなみに、段ボール等の着色された紙を抄紙機にて製造する場合、アルキル基が低分子のポリエチレンアルキルエーテルを乳化剤として用いると、紙の色を脱落させ、紙の色が斑になる欠点がある。しかし、アルキル基がデシル基、セチル基、ステアリル基のポリエチレンアルキルエーテルを乳化剤として用いると、色抜けが抑制される。
高分子ポリシロキサン化合物の配合割合が1質量%未満であると、高分子ポリシロキサン化合物の配合割合が上記範囲内にある場合と比較して、皮膜を十分に形成できない場合があり、高分子ポリシロキサン化合物の配合割合が20質量%を超えると、高分子ポリシロキサン化合物の配合割合が上記範囲内にある場合と比較して、汚染防止剤組成物自体のタック性が大きくなり、紙面が毟れる恐れがある。
低分子ポリシロキサン化合物の配合割合が5質量%未満であると、低分子ポリシロキサン化合物の配合割合が上記範囲内にある場合と比較して、ピッチを十分に分散できなくなる場合があり、低分子ポリシロキサン化合物の配合割合が20質量%を超えると、ピッチの分散効果が飽和し、結果として高コストとなる欠点がある。
高分子ポリシロキサン化合物1質量部に対する低分子ポリシロキサン化合物の配合割合が0.1質量部未満であると、配合割合が上記範囲内にある場合と比較して、汚染防止剤組成物自体の粘着性が高くなり、ドライパートに均一に付与できなくなる場合があり、高分子ポリシロキサン化合物1質量部に対する低分子ポリシロキサン化合物の配合割合が10質量部を超えると、配合割合が上記範囲内にある場合と比較して、ドライパート部位の表面上に皮膜が定着せずに、分散されたピッチが再付着してしまう虞がある。
乳化剤の配合割合が0.05質量部未満であると、乳化剤の配合割合が上記範囲内にある場合と比較して、乳化安定性が不十分となる場合があり、乳化剤の配合割合が0.4質量部を超えると、乳化剤の配合割合が上記範囲内にある場合と比較して、紙の色抜けの度合いが大きくなる欠点がある。
汚染防止剤組成物は、高分子ポリシロキサン化合物及び低分子ポリシロキサン化合物と、乳化剤とを、水に加えて撹拌することにより、高分子ポリシロキサン化合物及び低分子ポリシロキサン化合物が乳化された汚染防止剤組成物が製造される。

図1に示すように、汚染防止剤組成物は、ドライパートDで用いられる。
その後、紙体Wは、ブレーカースタックロールBに挟持され、次いで、紙体Wは、カレンダーロールCにより高密度化される。
ここで、汚染防止剤組成物の付与方法は特に限定されず、例えば、散布ノズル等を用いて液状のシャワー方式や霧状の噴霧方式等が用いられる。このとき、散布ノズルを紙幅方向にスライドさせながら、汚染防止剤組成物を吹きつけてもよい。汚染防止剤組成物をドライパートに吹き付けることにより、ピッチ汚染が防止される。
散布量が10μg/m2未満であると、散布量が上記範囲内にある場合と比較して、汚染防止剤組成物が十分にドライパート部位の表面に付着せず、ピッチの付着を十分に抑制できない傾向にある。また、散布量が10000μg/m2を超えると、散布量が上記範囲内にある場合と比較して、余剰分がドライパート部位の表面上に蓄積し、ピッチを巻き込んで汚れを増大させたり、カンバスの目を詰まらせてしまう虞がある。
なお、エポキシ変性基としては、エポキシアルキル基又はエポキシポリエーテル基が挙げられる。
下記式(1)で表される低分子ポリシロキサン化合物6.0質量%と、下記式(2)で表される高分子ポリシロキサン化合物4.0質量%と、ポリエチレンデシルエーテル(乳化剤)2.0質量%とを水に加え、ミキサーで撹拌することにより、汚染防止剤組成物を得た。
