Abstract
【解決手段】(A)シリコーンエマルジョン、(B)ウレタン樹脂系水性エマルジョンまたはウレタン樹脂系水性分散物、並びに(C)分子鎖末端に少なくとも1つのエポキシ基を有するシランおよび/またはその部分加水分解物を含有する離型剤組成物である。

Description
請求項5に記載の発明は、請求項1乃至4のいずれか1項記載の離型剤組成物において、前記(B)成分の樹脂分が、ポリヒドラジド類およびカルボニル基含有ポリウレタン・ビニル・ハイブリッドポリマーであることを特徴とする。
シリコーンエマルジョンとして25℃における粘度が100,000mPa・sの両末端水酸基閉鎖乳化重合ポリジメチルシロキサンエマルジョン(シリコーン分33重量%)、ウレタン樹脂系水性エマルジョンとしてポリヒドラジドおよびカルボニル基含有ポリウレタン・ビニル・ハイブリッドポリマー含有水性エマルジョン(ソルーシア・ジャパン社製 商品名 Daotan VTW 6462、固形分36重量%)、γ−グリシドキシプロピルトリメトキシシラン、γ−メタクリロキシプロピルトリメトキシシラン、ジメチルラウリルアミンオキサイド、および水を用い、表1に示す配合割合で各成分を均一に混合して離型剤組成物を調製した。
すなわち、離型剤組成物を刷毛にて加硫ブチルゴムシート(5cm×5cm×1cm)の主面上に塗布量5g/m2で均一に塗布した。風乾後、塗布面に未加硫のブチルゴムシート(5cm×5cm×1cm)を重ね、10kgの荷重をかけ、190℃で10分間加熱加圧して、未加硫のブチルゴムシートを加硫させた。この後、これらの2枚のゴムシートを1kgスケールのプッシュプルゲージを用いて引き剥がし、初回剥離力を測定した。次いで、引き剥がし後の加硫ブチルゴムシート上に新たに未加硫のブチルゴムシート(5cm×5cm×1cm)を重ね、1枚目の場合と同様にして加硫させ、剥離力を測定した。この操作を繰り返し、剥離力が0.5kgf/5cmを超えるまでの加硫成形回数を調べた。
