Description
各薬品の部数は有効成分基準の重量部で示し、米坪及び塗工量は乾燥重量基準で示す。
LBKP:NBKPの比率(重量比)を70:30として各パルプを配合した。各パルプについて、カナダ型濾水度測定器(東洋精機製作所社製)を使用し、JIS P 8121に準じて測定を行い、表1記載のフリーネスとした。パルプ全体のフリーネスは表1記載のとおりとなった。抄紙機としては長網ヤンキー抄紙機、又は長網多筒抄紙機を使用し、表1の米坪となるように抄造した。
目止め層を設けたものについては、ポリビニルアルコール(クラレ社製、品番:PVA117)を表1の塗工量でサイズプレスにて塗工した。
各剥離剤を、各原紙の表裏に各々1.5g/m2でバーコーターにて塗工した後、140℃で20秒間乾燥しキュアさせた。
「エマルジョン」:シリコーンエマルジョン(信越化学工業社製、品番:SM−3951)100部と白金系触媒(信越化学工業社製、品番:CAT−PM−10A)2.5部を混合し、塗工した。
「無溶剤」:無溶剤シリコーン(信越化学工業社製、品番:KNS−320)100部と白金系触媒(信越化学工業社製、品番:CAT−PL−56)2部を混合し、塗工した。
「溶剤」:溶剤シリコーン(信越化学工業社製、品番:KS−847)100部と白金系触媒(信越化学工業社製、品番:CAT−PL−50T)1部を混合し、塗工した。
(1)透気度:ガーレーデンソメーター(熊谷理機工業社製)を使用し、JIS P 8117に準じて測定した。
(2)ガーレー剛度(縦方向):ガーレー剛度測定器(東洋精機製作所社製)を使用し、J.TAPPI No.40に準じて測定した。
○:5〜50gf/40mmであり、良好である。
×:50gf/40mmを超えるため、剥離不良が考えられる。(剥がれない、または工程紙の層間剥離)
−:5gf/40mm未満であり、プリプレグの担持性なしとみなされ、評価できず。
面積寸法変化率(%)=〔(23℃50%RHの面積−絶乾状態(23℃、dry)の面積)/絶乾状態(23℃、dry)の面積〕×100
◎:全く浮きが見られなかった。
〇:わずかに浮きが見られたが、問題ないレベルであった。
×:浮きが大きく、剥がれかけていた。
−:剥離不良のため問題外
◎:全く浮きが見られなかった。
〇:わずかに浮きが見られたが、問題ないレベルであった。
×:浮きが大きく、剥がれかけていた。
−:剥離不良のため問題外
◎:腰があり、安定していた。
〇:ややクネクネしたが、作業性に問題はなかった。
×:持ち方によっては意図せずに曲がってしまい、作業性が悪い。
各評価結果を表1に示す。
Claims (1)
