Description
FF−5(27mPasの4%粘度(Brookfield LV 60rpm、25℃)、MW 50kD、DS 0.7)グレードCMCを4つのCMC濃度:約5、13、17、および20%CMCで用い、CMC溶液を調製した。2%Na2CO3をCMCと予めブレンドし、「実験」溶液を生成した。各溶液の粘度を測定し、その結果は図1に見ることができる。粘度測定:Brookfield RV 100rpm、50℃。粘度を測定する前に、CMCおよびCMC+塩のドライブレンドを、ワイヤミキサーを用いて90分間水と混合した。
各種濃度のアルカリ塩およびNaClを20%CMC濃度のCMC溶液に添加し、表1に示されるようなCMC溶液を生成した。基準CMC:FF−5(27mPasの4%粘度、DS 0.7)。粘度測定:Brookfield RV 100rpm、60℃。粘度を測定する前に、CMCおよびCMC+塩のドライブレンドを、ワイヤミキサーを用いて90分間水と混合した。粘度測定は溶液上で行い、その結果は表1および図2に示す。
アルカリ塩を含む、および含まない両方のCMC溶液を、以下の表2に記載される各種グレードのCMCを用いて調製した。pHおよび粘度を測定する前に、CMCおよびCMC+アルカリ塩(2%炭酸ナトリウム)のドライブレンドを、ワイヤミキサーを用い、90分間水中に混合した。
適用試験を、100pph(100分の1部)のCaCO3、10pphのSB−ラテックス、0.15pphのCMCおよび0.3pphの光学増白剤を有する標的コーティングカラー製剤で行った。コーティングカラー製剤の固体含有量は70wt%であり、pHを水酸化ナトリウムの添加により8.5に調節した。CMCを、Na2CO3(1または2%Na2CO3)を含む、および含まない両方の、予め溶解したCMC FF−5の20%溶液として添加した。コーティングされた紙のコーティングカラーのレオロジー、保水、および光学特性をこれらの試料について特徴づけ、図4〜7に示す。
CMCを含有する4つのバリア材料を生成し、KIT試験を用いて評価し、それらの耐油性を決定した。耐油性はより高いKIT試験スコアを有するそれらのバリア材料についてより良好である。
