本発明は(A)セルロース又はセルロース誘導体の粒子と、該粒子の表面に付着しているポリオルガノシルセスキオキサンとから成る複合粒子の製造方法であって、前記(A)粒子の100質量部に対し3~80質量部の(B)オルガノトリアルコキシシランを、前記(A)粒子と、水と、アルカリの存在下で加水分解及び縮合反応させてポリオルガノシルセスキオキサンを形成し該ポリオルガノシルセスキオキサンを前記(A)粒子の表面に付着させる工程を含む、前記複合粒子の製造方法を提供する。その後、水を除去する工程を含む。ここで、ポリオルガノシルセスキオキサンはRSiO3/2単位からなる重合体である。以下、本発明の製造方法について詳しく説明する。
平均粒径7μmの球状セルロース粒子(A-1)100質量部、イオン交換水830質量部、塩化ドデシルトリメチルアンモニウム(カチオンBB、日油製カチオン乳化剤)1.6質量部を500ml反応器に投入し、30分攪拌した。25%アンモニア水22質量部を加え、pH11~12(卓上pHメーターHM-42X(東亜DKK(株)製)にコントロールし、5℃まで冷却した後、メチルトリメトキシシラン(KBM13、信越化学工業製)を22.5質量部、20分かけて投入した。8℃にて1時間熟成した後、55℃に昇温して25%アンモニア水53質量部を投入し1時間熟成し、スラリーを得た。スラリーを吸引ろ過して固液分離し、静置乾燥したところ、単分散で撥水性のある粉体となった。電子顕微鏡により、ポリメチルシルセスキオキサンが粒状セルロース粒子表面に付着している複合粒子であることが確認された。
メチルトリメトキシシランを15質量部とした以外は、実施例1の工程を繰り返して、単分散で撥水性のある粉体を得た。電子顕微鏡により、ポリメチルシルセスキオキサンが粒状セルロース粒子表面に付着している複合粒子であることが確認された。
メチルトリメトキシシランを55質量部とした以外は、実施例1の工程を繰り返して、単分散で撥水性のある粉体を得た。電子顕微鏡により、ポリメチルシルセスキオキサンが粒状セルロース粒子表面に付着している複合粒子であることが確認された。
平均粒径7μmの球状セルロース粒子を平均粒径15μmの球状セルロース粒子(A-2)に替え、メチルトリメトキシシランの量を40質量部とした以外は実施例1の工程を繰り返して単分散で撥水性のある粉体を得た。
この複合粒子を電子顕微鏡で観察したところ、粒子表面に粒径約100nmを有する粒子が確認された。また赤外吸収スペクトルを臭化カリウム錠剤法によりFT-IR測定装置(島津製作所製)で測定したところ、波数2960cm-1、1260cm-1、及び1100~1020cm-1に特性吸収を認めた。これにより、ポリメチルシルセスキオキサンが粒状セルロース粒子表面に付着している複合粒子であることが確認された。上記複合粒子の表面を観察した電子顕微鏡写真を図1に示す。また、上記複合粒子の表面を観察した電子顕微鏡写真(a)と、これに対応する、SwiftED3000(HITACHI製)で分析したケイ素の元素マッピング画像と炭素の元素マッピング画像を重ね合わせた画像(b)を図2に示す。
平均粒径7μmの球状セルロース粒子を平均粒径15μmの球状セルロース粒子(A-2)に替え、メチルトリメトキシシランの量を15質量部とした以外は実施例1の工程を繰り返して複合粒子を得た。
実施例1のセルロース粒子を、平均粒径5μmを有する球状セルロース粒子(A-3)に替えた以外は実施例1の工程を繰り返して複合粒子を得た。
セルロース粒子(A-1)、(A-2)、及び(A-3)を、メチルトリメトキシシラン処理を施さずに評価に供した。
メチルトリメトキシシランの量を表2に記載の量に変更した以外は実施例1の工程を繰り返して複合粒子を得た。比較例5の粒子表面の画像を図3に示す。
複合粒子10個の表面の電子顕微鏡写真から目視にて平均被覆率’を算出した。
被覆率=被覆面積/表面積×100
として計算した。
上記粉体試料適量を指に付着させ、黒色カーボン紙上に接触させ紙面上を一気に滑らせる。滑らせた時の感覚を触感、またその滑らせた跡がどれだけ長く伸びているかを伸び性とし、下記の3水準で評価した。
○:特有の良好な滑り感がある
△:やや良好な滑り感がある
×:指に抵抗を感じ滑り感がない
上記粉体試料約1gをバイオスキンプレート(Beaulax製)上に均一に塗延ばして複合粒子からなる複合体を有する試料片を作成した。HEIDON TYPE-38(新東科学社製)にて100gの重りを載せた圧子を上記試料片の複合体に垂直に接触させ、3cm/分で移動させた時の摩擦力を測定し、摩擦力から摩擦係数を算出した。圧子には接触面が直径12mmで、複合体との接触面に人工皮革サプラーレを装着したものを用いた。
複合粒子からなる複合体の静・動摩擦係数の好ましい範囲は、0.4以下がよく、静摩擦係数、動摩擦係数はいずれも0.01~0.40である。静・動摩擦係数ともに、値が小さいほうが摺動性は良好であることを示しており、特に0.4以下であるとなめらかさ、滑りやすさが良好であり、好ましい。
静摩擦係数は静止状態から動き出すのに必要な力の指標となり、大きいと引っかかりや軋みを感じやすい。
接触角の測定は下記のようにして行った。
上記摩擦係数測定と同様の試料片を作成し、その上に10μmの水滴を滴下し、0.3秒後の接触角値を協和界面科学社製接触角計CA-D型を用いて測定した。撥水性剤量として好ましい範囲は、接触角が110°以上である。
粉体試料5gをクリアラッカー45gに投入しディスパーミキサー3000rpmで2分間分散した。分散液を黒色カーボン紙上に直径2cm円になるよう垂らし、5MILのコーターで塗布し塗膜化した。風乾の後、グロス計で塗膜上の異なる3点を測定し平均値を採用した。85°の反射光強度が小さいほど、マットな仕上がりとなり、光拡散性が良いといえる。

A-3:平均粒径5μmセルロース粒子
B-1:メチルトリメトキシシラン(KBM13、信越化学工業社製)
