Abstract
Description
a)十分な架橋密度が得られるまで架橋反応を行うため、高温で非常に長い滞留時間
b)短時間の加熱の後でさえ所望の架橋密度まで架橋反応が進むように脂肪族イソシアネート基とイソシアネート反応性ポリマーとの間の反応を促進させる触媒
がいずれも必要である。
a)イソシアネート反応性基を有する少なくとも1つのポリマーの水性分散体または分散体混合物、
b)少なくとも実質的に水中において懸濁状態である微細に分割された表面不活性化固体脂肪族ポリイソシアネート、
c)各元素が少なくとも+4の酸化状態を有する、周期表の第5遷移族および第6遷移族の元素の少なくとも1つの化合物、および
d)必要に応じて、さらなる添加剤および助剤
の混合物である。
・水性ポリマー分散体に添加するか、
・固体脂肪族イソシアネートの調製/表面不活性化中に添加するか、または
・ポリマー分散体、表面不活性化固体イソシアネート、および適切な場合にはさらなる添加剤および助剤からなる処方物に添加する
ことができる。
(予備)被覆物、接着剤フィルム、接着剤不織布または接着剤パウダーを基材の表面上に塗布し、設置し、または散布して、接合(片面塗布)し、または接合すべき両方の基材表面上に塗布し、設置しまたは散布することができる(両面塗布)。特定の場合に最適な手順(片面塗布または両面塗布)は、熱可塑的に軟化した接着剤層での熱活性により基材表面の湿潤挙動を含む要素に依存し、当技術における当業者によって通常業務に関連して容易に決定することができる。
1.接着剤層の短時間の熱活性および架橋反応の開始:
潜在的反応性の被覆物、フィルム、不織布またはパウダーは短時間の熱活性によって、例えば加熱トンネル中で、IR放射によりまたはマイクロ波での放射によって、ポリマーの脱結晶化温度または固体イソシアネートの軟化温度を超える温度にまで加熱される。その直後、基材表面は圧力下に接合される。この場合における架橋反応は短時間の熱活性によってのみ開始される。架橋した接着剤層の最終特性は1〜5日後に達成される。かかる手順の優位性は、接合方法のための短い操作段階および熱活性のための比較的低い温度である。これは温感性基材が接合される場合に特に有利である。
潜在的反応性の被覆物、フィルムまたはパウダーは接合される基材との間にある。基材は、ポリマーの脱結晶化温度を越えるかまたは長期間の固体脂肪族イソシアネートの軟化温度を超える温度で圧力がかけられる。かくして、接着接合の最終特性は接合操作直後に達成することができる。かかる手順の優位性は、接着接合をさらに急速に処理することができることおよび/または接合操作直後に品質試験を実施できることにある。
かかる手順の優位性は短い接合作業において互いに基材を接合することができることである。次いで、最終架橋は第2段階で実施し、これは空間および時間の両方において最初の接合操作から分離することができる。

比較例(架橋剤1および2)
脱イオン化水、乳化剤、不活化性アミン、増粘剤および固形イソシアネートを、2000rpmで15分間にわたって溶解機ディスクを用いて均質な懸濁液に導入し、混合する。
触媒をまず、脱イオン化水に溶解した。次いで乳化剤、不活化性アミン、増粘剤および固形イソシアネートを添加し、2000rpmで15分間にわたって溶解機ディスクを用いて均質な懸濁液に混合する。
ポリマー分散体を導入する。表面不活性化固形イソシアネートの処方物を撹拌しながら添加する。
ポリマー分散体実施例1〜6を、200μmドクター刃を用いてブナ材試験試料(試験試料の寸法:50mm×140mm;4mm厚)に50mm×110mmの面積にわたって塗布し、23℃で1時間乾燥する。さらに3時間後、PVCシート(供給業者:Benecke)を80℃および100℃にて4バールの圧力下で5分間、10分間、30分間および60分間にわたって接着剤層上にラミネートした。プレスからブナ材/PVCボンドを取り出した直後、アセンブリを80℃に加熱した加熱キャビネット中で吊し、3分間状態調節した。その後、2.5kgの重さをそれぞれのPVCシート上に吊し、接着接合は、ピール試験(角度180°)により5分間にわたって80℃で負荷をかけた。
(注記:5mm/分未満の値の場合、接着剤層は架橋している;−はさらなる測定ができないことを意味する)
潜在的反応性パウダーの調製:
分散体2(比較例)および4(本発明)を急速冷凍により−5℃で24時間貯蔵した。かかる貯蔵の間に、ポリマーは粗い固体粒子の形態で沈殿する。処方物を室温に温め、沈殿ポリマーは濾過によって液相から分離した。次いで、該ポリマーを徐々に乾燥させ、ジェットミルにより、冷却しながら約100μmの粒度d50にまで細かくした。
2.4gのパウダーをポリエステル/綿ブレンド編織布(約70g/m2)の14cm×24cmの面積にわたり均一に散布した。次いで該ポリエステル/綿ブレンド編織布を皮膜プレスにより80℃のプレス温度にて1バールの圧力下、2分間、未被覆ポリエステル編織布に対してプレスした。接着接合を標準条件下(23℃相対湿度50%)、24時間貯蔵し、次いで長期間試験により試験した。
長期間試験のために、まず繊維製品接合を60℃に加熱した加熱キャビネット中に加重せずに吊し、30分間状態調節した。次いで接着接合(180°剥離試験)を50gの重さに荷重し、60℃でさらに30分間そのままにした。30分の試験の終了後、剥離間隔[mm]を測定した。次いで10℃毎の温度の上昇を30分間毎に行った。各温度段階の終了後、剥離間隔を計測した。
