Description
本発明の第1の形態においては、(a)ポリイソシアナートコンポーネントと(b)1種以上のポリオールを含むポリオールコンポーネントとを含む接着剤組成物であって、前記(a)ポリイソシアナートコンポーネントが(i)モノマー系4,4’メチレンジフェニルジイソシアナートおよび(ii)イソシアナート官能性プレポリマーを含み、前記(ii)イソシアナート官能性プレポリマーが(A)モノマー系4,4’メチレンジフェニルジイソシアナート、(B)225以下のOH当量を有する1種以上のジオール、および(C)1400以上のOH当量を有する1種以上のトリオールを含むプレポリマー反応物質混合物の反応生成物である、接着剤組成物が提供される。
0.5m3/hrの窒素スイープが維持された。反応器温度は35℃であった。I−AおよびI−Bが添加され、攪拌装置が運転開始され、約62rpmで運転された。一回ずつ、ポリオールが次の順に添加された:P−A、P−B、P−C、P−DおよびP−E。必要な場合には冷却を使用して、2.5時間の間、反応器は80℃〜84℃に維持された。生成物は窒素ブランケット下で密閉容器内に入れられた。
上述のように反応器内で窒素スイープが維持された。ひまし油がこの反応器に入れられ、攪拌装置が60〜65rpmの設定で作動させられた。P−F、P−GおよびTMPが添加された。反応器は80℃〜84℃に設定された。反応器は密閉され、窒素スイープが遮断された。この反応器は80℃〜84℃に60分間保持された。生成物は窒素ブランケット下で密閉容器内に入れられた。
ポリイソシアナートコンポーネントとポリオールコンポーネントとを一緒にした直後に、次いで、接着剤(周囲温度で)はポリタイプ(Polytype商標)ロールコーター上に供給された(40℃〜45℃に設定された計量ロール)。次いで、混合された接着剤は1.6〜2.2グラム/平方メートル、すなわち、1〜1.2 lbs./リームのカバレッジで、インラインコロナ処理された第1のウェブに適用され、次いで、接着剤でコーティングされた第1のウェブは第2のウェブと一体にされ、次いでこの積層膜はニップされ、ポリタイプ商標ラミネーター上で仕上げロールに巻き取られた。
適切な硬化時間の後で、15mm幅のストリップが仕上げロールから切り出され、そしてインストロン(Instron商標)引張試験機において、100mm/分(4インチ/分)の分離速度を用いて結合データが得られた。結果は積層物を剥離させるのに必要な力、グラム重として報告される(「f(g)」と略される)。破壊モードは以下のように報告される。
PAA試験のための積層物は上述のように製造された。第1の基体はナイロンであり、第2の基体はEVA修飾PEであった。EVA修飾PEは、EVA修飾のないPEよりも望ましくない移動性物質に対してより多孔性なので、EVA修飾PEがPAA試験のために選択される。EVA修飾PE以外の基体を用いて製造された積層物は概して、EVA修飾PEを用いて製造された積層物が行うよりも速いPAA低下を示す。よって、積層物がある接着剤組成物を用いて製造され、EVA修飾PEである少なくとも1つの基体を有し、かつ許容可能な素早いPAA低下を示す場合には、同じ特定の接着剤組成物を用いて製造された他の積層物も、許容可能なように少なくとも充分に素早いPAA低下を示すであろう。
以下のポリイソシアナートコンポーネント(PIC)は、以下の材料の組み合わせを使用して、実施例におけるように製造された。それぞれのPICについては、%NCOが示され、25℃(ブルックフィールド粘度計DVII+によって、#27スピンドルを用いて、20rpmで測定される)でのPICの粘度も示される。各材料の量は重量部である。番号中に「C」を伴うPICは比較例である。
(2)少量の2,2’MDIを含む4,4’MDI、2,4’MDIおよび2,2’MDIの混合物
(3)混合アジペートポリエステル
(4)ポリオール(B)としての資格を有する
(5)ポリオール(C)としての資格を有する
(6)ポリオール(D)としての資格を有する
これら実施例のポリイソシアナートコンポーネントの全ては11%を超える%NCOを有しており、かつ全ては25℃で、13.6Pa*s以下の粘度を有していた。
以下の接着剤組成物(AC)が製造され試験された。それぞれの組成物において、100部のPICが使用された。新たに混合された接着剤組成物の粘度(混合粘度)が40℃(示される場合を除く)で、ブルックフィールド粘度計DVII+、#27スピンドルを用いて、20rpmで測定された。第1の基体はPETであり、第2の基体はPEであった。引張試験が上述のように行われた。番号に「C」を伴う接着剤組成物は比較例である。
