Description
この実施例では、2種の異なるスチレン−ブタジエン水不溶性膜形成ポリマー(ベースポリマーまたはラテックス)と組み合わせて再利用ポリウレタン硬質フォーム粉末(RPU)を含有する2種の再分散性ポリマー粉末複合体を、急速オープンタイム、接着、加工性、耐衝撃性および水取込みについて外部セメント系タイル接着剤(CBTA)で評価する。再分散性ポリマー粉末複合体の一方については、スチレン−ブタジエン水不溶性膜形成ポリマーは、62部のスチレン、35部のブタジエンおよび3部のイタコン酸のコモノマー含量(総コモノマー重量基準で3重量%のイタコン酸のカルボキシル化)ならびに8℃のTgを有する。他方の再分散性ポリマー複合体については、スチレン−ブタジエン水不溶性膜形成ポリマーは、51.6部のスチレン、45.4部のブタジエンおよび3部のイタコン酸のコモノマー含量(総コモノマー重量基準で3重量%のイタコン酸のカルボキシル化)ならびに−15℃のTgを有する。内部添加剤として再利用ポリウレタン硬質フォームを含まないSB RDP配合物も、62部のスチレン、35部のブタジエンおよび3部のイタコン酸のコモノマー含量(総コモノマー重量基準で3重量%のイタコン酸のカルボキシル化)ならびに8℃のTgを有するスチレン−ブタジエン水不溶性膜形成ポリマーを使用して比較のために評価する。
この試験の目的は、タイルをタイル接着剤のコーム床(combed bed)に置いた時にタイルの裏面がまだ十分に湿っている期間を決定することである。原理は、タイルを5分間隔でタイル接着剤のコーム床に置き、後で取り除くというものである。その後、タイルの背面の湿潤を評価する。
モルタルを適当な熟成時間後にEN−1348にしたがって混合する。混合後、モルタルを、気泡の存在を防ぐために軽くつつきながら、カップに充填する。試料を貫入試験機の内側の適当なホルダーに入れ、所望の測定プログラムを選択し、試験を操作指示書に記載されているように開始する。貫入試験機は、硬化が開始した時(貫入深さ:36mm)および硬化が終了した時(貫入深さ:2mm)を決定する。2つの時間の間の差が硬化持続時間である。間違った結果をもたらし得るような任意の測定欠陥がグラフ上で検出できた場合、硬化が開始した時および硬化が終了した時を内挿により補正すべきである。
この欧州規格は、セラミックタイル接着剤のオープンタイムを決定するための試験法を定める。この規格は、壁および床への内部および外部タイル取り付けのための全てのセラミックタイル接着剤に適用可能である。標準条件下での28日の貯蔵後、(250±50)N/sの一定の速度で増加する力を印加することにより、接着剤の引張接着強度の決定を行う。オープンタイム(分)は、接着剤が0.5N/mm2の引張接着強度を満たす最大時間間隔である(EN12004)(表5)。
この欧州規格は、セメント系セラミックタイル接着剤の引張接着強度を決定するための試験法を定める。この規格は、壁および床への内部および外部タイル取り付けのための全てのセラミックタイル接着剤に適用可能である。異なる条件下での貯蔵後、(250±50)N/sの一定の速度で増加する力を印加することにより、接着剤の引張接着強度を決定する。EN1348による貯蔵条件は以下である:a)標準貯蔵:28日23℃/50%相対湿度、b)水浸:7日標準気候貯蔵/20日水浸/1日標準気候貯蔵、c)熱老化:14日標準気候貯蔵/14日 70℃で貯蔵/1日標準気候貯蔵は分析しなかった、およびd)凍結−融解サイクル:7日標準貯蔵/21日水浸/25凍結−融解サイクル(2時間以内に−15℃に冷却、2時間−15℃で貯蔵、2時間水浸、25回繰り返す)。
この実施例では、実施例1の2種の異なるスチレン−ブタジエン水不溶性膜形成ポリマー(ベースポリマーまたはラテックス)と組み合わせて2種の異なる再利用ポリウレタン軟質フォーム粉末(MPU200RおよびMPU200R3%)を含有する再分散性ポリマー粉末複合体を、実施例1のようにオープンタイムおよび接着について外部セメント系タイル接着剤(CBTA)で評価する。内部添加剤として再利用ポリウレタン硬質フォーム粉末を含まないSB RDP配合物も、62部のスチレン、35部のブタジエンおよび3部のイタコン酸のコモノマー含量(総コモノマー重量基準で3重量%のイタコン酸のカルボキシル化)ならびに8℃のTgを有する実施例1のスチレン−ブタジエン水不溶性膜形成ポリマーを使用して比較のために評価する。再利用ポリウレタン軟質フォームMPU200Rは、80〜120μmのX−50粒度を有し、10重量%のシリカで処理されている。再利用ポリウレタン軟質フォームMPU200R3%は、100μmのX−50粒度を有し、3重量%のシリカで処理されている。
