Description
分子鎖両末端が水酸基で封鎖されたα,ω−ジヒドロキシポリジメチルシロキサン(粘度5,000mPa・s)50部に、ステアリン酸で表面処理された合成炭酸カルシウム(以下、合成炭酸カルシウムについては、単に炭酸カルシウムと示す。)であるカルファイン500(商品名;丸尾カルシウム(株)製)(電子顕微鏡法により測定された平均粒径0.05μm、BET比表面積17m2/g)を添加して混合し、これを主剤とした。
実施例2〜20においては、配合する主剤各成分の種類および量を表2および表3に示すように変えるとともに、硬化剤各成分の種類および量を表4および表5に示すように変えた。それ以外は実施例1と同様にして、主剤および硬化剤をそれぞれ調製した。そして、主剤と硬化剤とを100:10の重量比で混合し、ポリオルガノシロキサン組成物を得た。
<スナップタイムの測定>
組成物を23℃、50%RHの雰囲気中に押し出した後、指で押出し物の表面に接触して乾燥状態にあることを確認するに至る時間を測定した。
JIS K5758建築用シーリング材に規定する方法に準じて、接着耐久性試験体を作成した。すなわち、主剤と硬化剤とを混合して得られたポリオルガノシロキサン組成物を2枚のフロートガラス板(JIS R3202に規定されたフロート板ガラス)の間に充填した後、温度23℃、湿度50%の条件で7日間放置し、組成物を硬化させた。こうして得られた試験体(H型試験体)について引張試験を行い、50%モジュラス(M50)、最大引張応力(Tmax)、最大荷重時の伸び(Emax)をそれぞれ調べた。合わせてシリコーンゴムの破断状態を観察し、接着性を調べた。さらに、同様の試験体を80℃の温水に14日間浸漬したものについてそれぞれ引張り試験を行い、50%モジュラス(M50)、最大引張応力(Tmax)、最大荷重時の伸び(Emax)および接着性をそれぞれ測定した。なお、破断状態におけるCFは凝集破壊(シリコーンゴム層で破壊)を、TCFは薄層破壊(ガラス板との界面でシリコーンゴムの薄層を残して破壊)を、AFは接着破壊(ガラス板とシリコーンゴムの界面で剥離)をそれぞれ表している。
