Abstract
Description
湿気硬化性組成物は、末端に架橋性シリル基を有するポリオキシアルキレン系重合体(以下、単に「ポリオキシアルキレン系重合体」ということがある)を含有している。ポリオキシアルキレン系重合体の主鎖は、一般式(1)で表される繰り返し単位を含有する重合体が好ましい。
−(R1−O)n− (1)
(式中、R1は炭素数が1〜14のアルキレン基を表し、nは、繰り返し単位の数であって正の整数である。)
測定装置 TOSOH社製 商品名「HLC-8121GPC/HT」
測定条件 カラム:TSKgelGMHHR-H(20)HT×3本
TSKguardcolumn-HHR(30)HT×1本
移動相:o−DCB 1.0mL/分
サンプル濃度:1mg/mL
検出器:ブライス型屈折計
標準物質:ポリスチレン(TOSOH社製 分子量:500〜8420000)
溶出条件:145℃
SEC温度:145℃
湿気硬化性組成物は水溶性ポリマーを含有している。水溶性ポリマーとは、水に可溶なポリマーをいう。具体的には、水溶性ポリマーとは、ERT470.2−02で規定されるExt(水可溶分)が50質量%以上であるポリマーをいう。
湿気硬化性組成物は、無機充填材を含有していてもよい。湿気硬化性組成物に無機充填材を含有させることによって、湿気硬化性組成物の硬化物の強度が向上する。
湿気硬化性組成物は、シランカップリング剤を更に含有していてもよい。シランカップリング剤を含有することにより、湿気硬化性組成物に優れた接着性を付与することができる。
湿気硬化性組成物は、シラノール縮合触媒を含有していてもよい。シラノール縮合触媒とは、ポリオキシアルキレン系重合体が有する架橋性シリル基同士の縮合反応を促進させるための触媒である。
湿気硬化性組成物は、脱水剤を含有していることが好ましい。脱水剤によれば、湿気硬化性組成物を保存している際に、空気中などに含まれている水分によって湿気硬化性組成物が硬化することを抑制することができる。
湿気硬化性組成物は、可塑剤、酸化防止剤、紫外線吸収剤、耐光安定剤、顔料、染料、沈降防止剤などの他の添加剤を含んでいてもよい。なかでも、可塑剤と酸化防止剤が好ましく挙げられる。
・主鎖骨格(ポリオキシプロピレン)の末端にジメトキシシリル基を有するポリオキシアルキレン系重合体(数平均分子量:10000、分子量分布:1.49、ウレタン結合を有しない、カネカ社製 製品名「サイリルEST280」)
・ポリビニルアルコール(ケン化度:98モル%、日本酢ビ・ポバール社製 製品名「JF−17S」、粒子状、粒子径:150μm以下(#100メッシュフルパス))
・カルボキシメチルセルロースナトリウム (第一工業製薬社製 製品名「セロゲンBS」、粒子状、粒子径:180μm以下(#70メッシュフルパス))
・重質炭酸カルシウム(白石カルシウム社製 製品名「ホワイトンSB」)
・ビニルトリメトキシシラン(信越化学工業社製 製品名「KBM−1003」
・ジブチル錫ビス(トリエトキシシリケート)(日東化成社製 製品名「ネオスタンS−303」)
架橋性シリル基を有するポリオキシアルキレン系重合体、水溶性ポリマー、無機充填材、脱水剤、及びシラノール縮合触媒をそれぞれ、表1に示す配合量となるようにして、密封した攪拌機中で減圧しながら均一になるまで混合することにより湿気硬化性組成物を作製した。
湿気硬化性組成物を、厚さ約3mmの型枠にスパチュラを用いて充填し、湿気硬化性組成物の表面を平滑面に整えた。湿気硬化性組成物の表面を平滑面に整え終わった時点を測定開始点とした。表面をスパチュラで触り、スパチュラに湿気硬化性組成物が付着しなくなった時点を測定終了点とした。測定開始点から測定終了点までの時間を算出して表面皮張り時間とした。
湿気硬化性組成物の23℃雰囲気下における粘度をJIS K6833に準拠してB型粘度計を用いて回転数10rpmの条件にて測定し、得られた湿気硬化性組成物の粘度を「初期粘度」とした。
粘度変化=貯蔵後粘度/初期粘度
湿気硬化性組成物を第1合板下地上に櫛目ごてを用いて塗工した。湿気硬化性組成物の塗工面上に別の第2合板を積層し、第1合板上に1kgの重錘を載置して合板同士が接近する方向に押圧して試験体を作製した。上述の要領で試験体を40個作製した。
