Description
本申請案主張2015年5月19日申請之國際申請案第PCT/CN15/079255號之權益。
本發明係關於一種可固化水性組合物,一種用於使用可固化水性組合物形成經處理可撓性基板之方法,及因此處理之基板。
諸如紙張、編織品及非編織品之可撓性基板經常藉由用聚合黏合劑處理來固結或加強,以安置於基板中或基板上。所述聚合黏合劑在此項技術中可稱為可固化水性組合物。呈乾燥、水浸沒(濕潤)或異丙醇浸沒(IPA)狀態之經處理基板之抗張強度為一個反映可固化水性組合物之品質的最重要特性。當經可固化水性組合物處理之基板具有高乾燥、濕潤或IPA抗張強度時,其通常具有改良特性,包含回彈性、抗裂性、耐乾洗性、洗滌持久性、撕裂強度及耐摺疊性。
在許多情況下,可固化水性組合物以實質上熱塑性或實質上未交聯之狀態存在,以使得可固化水溶液或分散液接觸基板後,可發生流動、滲透、膜形成及類似行為。為增強經處理基板之特性,經常需要在可固化水性組合物達至
其最終位置時或同時使用乾燥方法實現交聯。諸如共聚合N-羥甲基丙烯醯胺(NMA)及經添加脲/甲醛樹脂之許多習知交聯劑本質上含有或釋放甲醛。另外,含NMA之可固化水性組合物在加熱時甚至釋放更多的甲醛。
因此需要提供一種具有良好抗張強度之環境友好型可固化水性組合物。
本發明提供一種包括(共)聚合物及環氧交聯劑之可固化水性組合物。(共)聚合物包括按(共)聚合物之總單體計,以乾重計0.05%至10%之具有至少兩個羧酸基團之烯系不飽和酸性單體,來作為(共)聚合單元。環氧交聯劑為具有至少兩個反應性環氧乙烷基團之脂族化合物。
本發明進一步提供一種用於形成經處理基板之方法,其包括步驟:i)形成包括(共)聚合物及環氧交聯劑之可固化水性組合物,所述(共)聚合物包括按(共)聚合物之總單體計,以乾重計0.05%至10%之具有至少兩個羧酸基團之烯系不飽和酸性單體,來作為(共)聚合單元,且所述環氧交聯劑為具有至少兩個反應性環氧乙烷基團之脂族化合物;ii)使可撓性基板與可固化水性組合物接觸;及iii)在80℃至250℃之溫度下加熱可固化水性組合物。本發明進一步提供一種由以上方法形成之基板。
出於描述本發明組合物中之組分的目的,所有包
括圓括號的短語指示所包含之圓括號裏的物質及其不存在中之任一者或兩者。舉例而言,短語「(共)聚合物」包含聚合物、共聚物及其混合物;且短語「(甲基)丙烯酸酯」意謂丙烯酸酯、甲基丙烯酸酯及其混合物。
可固化水性組合物包括(共)聚合物及環氧交聯劑。

在一些實施例中,(共)聚合物進一步包括按(共)聚合物之總單體計,以乾重計小於5%、較佳小於2%且更佳小於1%之(共)聚合多烯系不飽和單體。多烯系不飽和單體包含(甲基)丙烯酸烯丙酯、鄰苯二甲酸二烯丙酯、1,4-丁二醇二(甲基)丙烯酸酯、1,3-丁二醇二(甲基)丙烯酸酯、1,2-乙二醇二(甲基)丙烯酸酯、1,6-己二醇二(甲基)丙烯酸酯及二乙烯基苯。
可固化水性組合物可包括至少兩種不同(共)聚合物。對於兩種或兩種以上乳液或溶液聚合物之混合物,應自(共)聚合物之總組成來測定具有至少兩個羧酸基團之(共)聚合烯系不飽和酸性單體的含量,而不考慮其中(共)聚合物之數目。
用以製備水性乳液或溶液(共)聚合物之乳液或溶
液聚合技術在此項技術中熟知,且揭示於至少美國專利第4,325,856號;第4,654,397號;第5,314,943號;及第4,814,373號中。習知界面活性劑可用作陰離子及/或非離子乳化劑,諸如鹼金屬烷基硫酸鹽或烷基硫酸銨、烷基磺酸、脂肪酸及氧乙基化烷基酚。所使用界面活性劑的量按總單體之乾重計通常為以乾重計0.1%至6%。可使用熱或氧化還原引發製程。可使用習知自由基引發劑及適合實例包含過氧化氫、氫過氧化第三丁基、氫過氧化第三戊基、過氧硫酸銨及鹼金屬過氧硫酸鹽,按總單體之乾重計,含量典型地為以乾重計0.01%至3.0%。可在類似水準下使用氧化還原系統,所述氧化還原系統使用與適合還原劑(諸如亞硫酸氫鈉、異抗壞血酸及重亞硫酸鈉)偶合之相同引發劑,視情況與諸如鐵及銅之金屬離子組合,視情況進一步包含用於金屬之錯合劑。可使用諸如硫醇之鏈轉移劑,以調節(共)聚合物之分子量。單體混合物可以純淨形式或以水中之乳液的形式添加。單體混合物可使用均一或不同組合物歷經反應時間段以單次添加形式或以多次添加形式或連續地添加。諸如自由基引發劑、氧化劑、還原劑、鏈轉移劑、中和劑、界面活性劑及分散劑的額外成分可在任一階段之前、期間或之後添加。可採用產生多峰粒度分佈之製程,諸如揭示於美國專利第4,384,056號及第4,539,361號中之製程。
在另一實施例中,水性乳液(共)聚合物可由多階段乳液聚合製程製備,其中組成不同之至少兩個階段以依序方式聚合。此類製程通常導致形成至少兩種彼此不相容的聚合物組合物,藉此導致在聚合物粒子內形成至少兩個相。所
述粒子由各種幾何結構之兩個或兩個以上相構成,諸如芯/殼或芯/鞘粒子、殼相不完全地封裝芯之芯/殼粒子、具有芯之多樣性之芯/殼粒子及互穿網狀粒子。多分級乳液聚合物之階段中之每一者可含有選自本文中以上用於乳液聚合物所揭示之彼等之單體、界面活性劑及鏈轉移劑。對於多分級乳液聚合物,應由乳液聚合物之總組成測定共聚合二羧酸單體含量,而不考慮其中之階段或相之數目。用以製備所述多階段乳液聚合物之聚合技術在此項技術中熟知,且揭示於美國專利第4,325,856號;第4,654,397號;及第4,814,373號中。

將各可固化水性組合物(以乾重計4g)進入內徑為93mm之培養皿中,且在適當攪拌下用13.33g DI水稀釋。在室溫下在不振動之情況下將培養皿放在平整表面上,持續4天。隨後自培養皿移除乾燥膜。所有膜為大約0.5至0.6mm厚。在150℃下固化膜3分鐘,之後測試。將固化膜切成22mm×5mm,且由英斯特朗(Instron)5943抗張測定器測試其楊氏模數。
2. 經處理非編織基板及抗張強度測試
將一片WHATMANTM 4級濾紙(28cm×46cm,沃特曼有限公司(Whatman Ltd.))浸入200mL可固化水性組合物中。由Mathis浸軋機浸軋經處理基板,且隨後在設計條件(120℃持續3分鐘或150℃持續3分鐘)下乾燥且固化。將紙張上之可固化組合物之附加物控制在28%與32%之間。將經固化基板切成1吋×5吋之片段,其中5吋方向為紙張之加工橫向。由英斯特朗5943抗張測定器,在乾燥(未經處理)、濕潤(浸沒於0.1% TRITONTM X-100溶液中30分鐘後)及「IPA」(浸沒於異丙醇中30分鐘後)之處理下,測試樣本之抗張強度。濕潤強度反映可固化水性組合物於水中之抗性,且IPA強度反映可固化水性組合物於溶劑中之抗性。強度愈
高,可固化水性組合物之效能愈好。
