次に示す合成樹脂エマルション1〜18をそれぞれ接着材1〜18として用いた。
反応容器に、脱イオン水104.4重量部を仕込み、攪拌及び窒素置換を行いながら80℃まで昇温した。これに、別途用意した乳化モノマー(脱イオン水42.2重量部にドデシル硫酸ナトリウム3.1重量部を溶解させた水溶液に、ブチルアクリレート89.6重量部、メタクリル酸5.2重量部、2−ヒドロキシエチルメタクリレート5.2重量部を乳化分散させたもの)、開始剤水溶液(脱イオン水7.6重量部に過硫酸アンモニウム0.4重量部を溶解させた水溶液)をそれぞれ3時間かけて連続的に滴下した(表1参照)。
滴下終了後3時間熟成し、30℃まで冷却した後、アンモニア水を添加してpHを8に調製することにより、合成樹脂エマルション1を得た。この合成樹脂エマルション1の樹脂固形分は40重量%、Tgは−36℃、酸価33KOHmg/g、水酸基価22KOHmg/gであった。
表1に示すモノマー配合に従った以外は、合成樹脂エマルション1と同様の製造方法で、合成樹脂エマルション2〜18を製造した。

エチレン−酢酸ビニル樹脂100重量部、メラミン75重量部、ジペンタエリスリトール75重量部、ポリリン酸アンモニウム370重量部及び酸化チタン105重量部を含む原料混合物を、ニーダーを用いて充分に混練後、押出し成形機によってシート状に加工し、膜厚1mmの熱発泡性シート2を作製した。
1.接着性試験1
熱発泡性シート1(25mm×50mm)の片面の半面(25mm×25mm)に接着材1を塗付け、23℃で3時間乾燥し、乾燥厚み70μmの第2接着材層を形成させた。一方、鋼板(150mm×70mm×1.6mm)の片面に接着材1を塗付け、23℃で3時間乾燥し、乾燥厚み30μmの第1接着材層を形成させた。
次に、熱発泡性シート1の接着材塗付け面(第2接着材層)と、鋼板の接着材塗付け面(第1接着材層)を、圧着して貼り合わせ、試験体を得た(なお、この試験体は、熱発泡性シート1の半面が鋼板に接着していない(非接着部分を有する)態様である)。この実施例1の試験体は、接着材層全体の厚みが100μm、厚み比は0.3/1である。
接着性試験1では、上記試験体を熱発泡性シート1が下側となるように水平に設置し、該熱発泡性シート1の非接着部分を90°に折り曲げ、熱発泡性シート1折り曲げ部分の先端に200gの重りを吊り下げ、鋼板から熱発泡性シート1が剥がれ落ちるまでの時間を測定した。評価は次の5段階で行った。結果は表2に示す。
A:2時間以上
B:1時間以上2時間未満
C:30分以上1時間未満
D:15分以上30分未満
E:15分未満
熱発泡性シート1(25mm×50mm)の片面の半面(25mm×25mm)に接着材1を塗付け、23℃で3時間乾燥し、乾燥厚み70μmの第2接着材層を形成させた。一方、鋼板(150mm×70mm×1.6mm)の片面に接着材1を塗付け、5℃で1時間乾燥し、乾燥厚み30μmの第1接着材層を形成させた。以後は、上記接着性試験1と同様の方法で試験体を作製し、接着性試験を行った。結果は表2に示す。
熱発泡性シート1(70mm×70mm)の片面の全面に接着材1を塗付け、23℃で3時間乾燥し、乾燥厚み70μmの第2接着材層を形成させた。一方、鋼板(150mm×70mm×1.6mm)の片面に接着材1を塗付け、5℃で1時間乾燥し、乾燥厚み30μmの第1接着材層を形成させた。
次に、熱発泡性シート1の接着材塗付け面と、鋼板の接着材塗付け面を、圧着して貼り合わせ、試験体を得た。
脱落試験1では、熱発泡性シート1が下側となるように水平に設置し、該試験体の上側25mmの位置にヒーター(ヒーター温度680℃)を設置し、ヒーターにより試験体を加熱し、鋼板から熱発泡性シート1が脱落したときの鋼板と熱発泡性シート1の境界面温度を測定した。評価は次の4段階で行った。結果は表2に示す。
◎:脱落温度320℃以上
○:脱落温度300℃以上320℃未満
△:脱落温度280以上300℃未満
×:脱落温度280℃未満
上記脱落試験1と同様の方法で試験体を得た。
脱落試験2では、試験体を垂直に設置し、試験体(熱発泡性シート1面側)から横方向に50cmの位置にプロパンガスバーナーを設置した。
脱落試験2では、プロパンガスバーナーにより試験体を1分加熱し、熱発泡性シート1の状態を評価した。評価は次の3段階で行った。結果は表2に示す。
○:脱落せず
△:一部脱落した
×:脱落した
実施例2〜実施例24、比較例1〜4では、使用した接着材の種類・全体厚み・厚み比、使用した熱発泡性シートの種類を表2に示す通りとした。それ以外は、実施例1と同様の方法で、試験体を作製し、各試験を行った。結果は表2に示す。
