Description
本發明是關於可回收交聯聚合物發泡材、使用其的可重複使用鞋類部件以及從其獲得的回收材料(reversed material)。
乙烯乙酸乙烯酯共聚物(ethylene vinyl acetate, EVA)發泡材是用於鞋類中底(midsole)的常用材料,因為它重量輕並且提供理想的緩衝性能。但是,它確實以缺乏耐用性而聞名。為了提高耐用性,EVA發泡材經過高度交聯,使其無法回收,造成大量的廢棄物。儘管熱塑性聚氨酯(thermoplastic polyurethane, TPU)等替代原材料是可回收的,但存在原材料成本高、設備更換成本高等缺點。
儘管現有的EVA發泡材已經足以滿足它們的預期目的,但它們不是在所有方面都完全令人滿意的。特別是,對具有可回收性和適當特性的EVA發泡材仍有未滿足的需求,以便在制鞋業和其他領域進一步利用。
本發明實施例提供了一種可回收交聯聚合物發泡材,包括以下之反應產物:100質量份之聚合物材料;0.1~10質量份之交聯劑;以及0.1~5質量份之自由基起始劑,其中交聯劑以下式表示:
其中R為碳原子數2~10的伸烷基、碳原子數6~18的亞芳基或碳原子數6~18的伸環烷基。
在一些實施例中,聚合物材料為乙烯類聚合物、聚烯烴聚合物、聚乙烯聚合物、丙烯聚合物、苯乙烯聚合物、乙烯丙烯二烯(ethylene-propylene-diene, EPDM)橡膠、天然橡膠(natural rubber, NR)、異丙烯橡膠(isopropylene rubber, IR)、其共聚物或其組合。
在一些實施例中,聚合物材料的乙酸乙烯酯含量(vinyl acetate content)為3-45質量%,熔融指數(melt index)為0.01-400g/10min。
在一些實施例中,交聯劑包括氨基甲酸酯雙四甲基哌啶氧化物(urethane bis-TEMPO(2,2,6,6-tetramethylpiperidinyloxy))。
在一些實施例中,氨基甲酸酯雙四甲基哌啶氧化物包括4,4-二苯甲烷二異氰酸酯氨基甲酸酯雙四甲基哌啶氧化物(4,4-diphenylmethane diisocyanate urethane bis-TEMPO)或4,4'-二異氰酸二環己基甲烷氨基甲酸酯雙四甲基哌啶氧化物(4,4’-diisocyanato dicyclohexylmethane urethane bis-TEMPO)。
在一些實施例中,自由基起始劑包括過氧化物。
在一些實施例中,過氧化物為過氧化二異丙苯(dicumyl peroxide)或雙-(三級丁基過氧化異丙基)苯過氧化物(bis-(tert-butylperoxy isopropyl) benzene peroxide, BIBP)。
在一些實施例中,可回收交聯聚合物發泡材為化學發泡製程的發泡產品。
在一些實施例中,化學發泡製程包括使用發泡劑,其中發泡劑包括偶氮化合物(azo compound)或醯肼化合物(hydrazide compound)。
在一些實施例中,偶氮化合物為2,2’-偶氮雙(2-氰基丁烷)(2,2’-azobis(2-cyanobutane))、2,2’-偶氮雙(甲基丁腈)(2,2’-azobis(methylbutyronitrile))或偶氮二甲醯胺(azodicarbonamide)。
在一些實施例中,醯肼化合物為p,p’-氧雙(苯磺醯肼)(p,p’-oxybis(benzene sulfonyl hydrazide))、對甲苯磺醯胺脲(p-toluene sulfonyl semicarbazide)或對甲苯磺醯肼(p-toluene sulfonyl hydrazide)。
在一些實施例中,可回收交聯聚合物發泡材為物理發泡製程的發泡產品。
在一些實施例中,自由基起始劑與交聯劑的莫耳比為0.1~5。
在一些實施例中,對於100質量份的聚合物材料,自由基起始劑與交聯劑的總和為0.5~15質量份。
在一些實施例中,可回收交聯聚合物發泡材的密度在0.05g/cm
3~0.8g/cm
3的範圍。
在一些實施例中,可回收交聯聚合物發泡材的泡孔尺寸為30μm~1mm。
本發明實施例還提供了一種可重複使用的鞋類部件,包括如上述之可回收交聯聚合物發泡材,其中可回收交聯聚合物發泡材的黃化指數(yellow index)為-5~70。
在一些實施例中,可重複使用的鞋類部件包括內底(insole)、中底(midsole)或大底(outsole)。
本發明實施例更提供了一種回收材料(reversed material),從如上述之可重複使用的鞋類部件獲得,其中回收材料的黃化指數為-5~95。
在一些實施例中,回收材料的黃化指數為-5~45。
本揭露的可回收聚合物組合物、聚合物發泡材、使用其的可重複使用的鞋類部件以及由此獲得的回收材料在以下描述中詳細描述。在以下詳細描述中,出於解釋的目的,闡述了許多具體細節和實施例以便提供對本揭露的透徹理解。為了清楚地描述本揭露,闡述了在以下詳細描述中的特定元件和配置。然而,顯而易見的是,這裡闡述的示例性實施例僅用於說明的目的,並且本發明構思可以以各種形式實施而不限於這些示例性實施例。
目前,乙烯-乙酸乙烯酯(ethylene vinyl acetate, EVA)經過交聯的發泡材一般是不可回收的。此外,在加熱回收的過程中,可能會出現黃化,這可能會限制回收材料進一步的應用。如果回收的發泡材料不是白色的,則所得產品只能是黑色或棕色等深色。為了解決上述問題,本案通過使用四甲基哌啶氧化物(2,2,6,6-tetramethylpiperidinyloxy, TEMPO)衍生物,將可熱降解的氨基甲酸酯鍵(urethane linkage)引入EVA系統中,從而提供具有所需性能例如低黃化指數的可回收交聯聚合物發泡材。
根據本揭露的一些實施例,本案的可回收交聯聚合物發泡材(例如,EVA發泡材)包括聚合物材料、交聯劑(即,TEMPO衍生物)和自由基起始劑。在發泡過程中,通過使用特定的交聯劑,以及控制自由基起始劑、交聯劑和聚合物材料的比例,可以獲得理想的性能。這導致了高交聯效率和可回收性,以及聚合物及其回收材料意外的低黃化指數,為可染色基材、鞋類、運動器材和家具等的進一步應用提供了靈活性。
在一些其他實施例中,本揭露提供的聚合物組合物也可以用作光伏模組(photovoltaic modules)中的封裝材料(encapsulant)。封裝材料透明度的降低可能導致光伏模組的電效率損失。通過調整封裝材料的顏色,可以調節透光率和太陽能光伏轉換效率。因此,黃化指數越低,太陽能光伏轉換效率越高。
根據一些實施例,本揭露提供了一種可回收交聯聚合物發泡材。可回收交聯聚合物發泡材包括以下之反應產物:100質量份之聚合物材料,0.1~10質量份之交聯劑以及0.1~5質量份之自由基起始劑。交聯劑以下式表示:
其中R為碳原子數2~10的伸烷(alkylene)基、碳原子數6~18的亞芳(arylene)基或碳原子數6~18的伸環烷(cycloalkylene)基。
根據本揭露的一些實施例,聚合物材料可以是聚烯烴聚合物、丙烯聚合物、聚乙烯聚合物、苯乙烯聚合物、乙烯類聚合物例如乙烯-乙酸乙烯酯(ethylene-vinyl acetate, EVA)、低密度聚乙烯(low-density polyethylene, LDPE)、線性低密度聚乙烯(linear-low-density polyethylene, LLDPE)、極低密度聚乙烯(very-low-density polyethylene, VLDPE)和高密度聚乙烯(high density polyethylene, HDPE)、二烯類橡膠,例如天然橡膠(natural rubber, NR)、異戊二烯橡膠(isoprene rubber, IR)、丁二烯橡膠(butadiene rubber, BR)、1,2-丁二烯橡膠、苯乙烯-丁二烯橡膠(styrene-butadiene rubber, SBR)、丙烯腈-丁二烯橡膠(acrylonitrile-butadiene rubber, NBR)、氯丁橡膠(chloroprene rubber, CR)、丁基橡膠(butyl rubber, IIR)、乙烯-丙烯橡膠(ethylene propylene rubber, EPR)和三元乙丙橡膠(ethylene-propylene-diene rubber, EPDM)或其組合。上述聚烯烴聚合物、丙烯聚合物、聚乙烯聚合物、苯乙烯聚合物和乙烯類聚合物各包括其隨機、嵌段和接枝共聚物。聚烯烴聚合物的例示包括烯烴嵌段共聚物(olefin block copolymers, OBC)。丙烯聚合物的實例包括丙烯乙烯共聚物。特別地,聚合物材料可以是三元乙丙橡膠(EPDM)橡膠、天然橡膠(NR)、異丙橡膠(isopropylene rubber, IR)或其組合。
在一些實施例中,乙烯類聚合物可以是LDPE。LDPE通常是高度分支的乙烯均聚物,可以通過高壓製程而製備(即高壓LDPE)。適用於本案的LDPE可具有0.91至0.94g/cm

3但小於0.94g/cm
3或小於0.93g/cm
3的密度的高壓LDPE。本文提供的聚合物密度根據美國材料和試驗協會(ASTM International,“ASTM”)方法D792測定。適用於本案的LDPE 可具有小於 40g/10min的熔融指數(melt index)或0.1-400g/10min、0.5-20g/10min、0.5-5g/10min、1-3g/10min的熔融指數或等於2g/10min的熔融指數。本文提供的熔融指數根據ASTM方法D1238測定。除非另有說明,否則熔融指數是在190°C和2.16kg下測定的。通常,LDPE具有較寬的分子量分佈,從而導致較高的多分散指數(polydispersity index, PDI;重均分子量與數均分子量之比)。
在一些實施例中,乙烯類聚合物可以是LLDPE。LLDPE通常是乙烯類聚合物,具有不均勻分佈的共聚單體(例如,α-烯烴單體),並且以短鏈分支為特徵。例如,LLDPE可以是乙烯和α-烯烴單體的共聚物,例如上述那些。適用於本案的LLDPE可具有0.916-0.925g/cm

在一些實施例中,乙烯類聚合物可以是VLDPE。VLDPE在本領域中也可稱為超低密度聚乙烯(ultra-low-density polyethylene, ULDPE)。VLDPE通常是乙烯類聚合物,具有不均勻分佈的共聚單體(例如,α-烯烴單體),並以短鏈分支為特徵。例如,VLDPE可以是乙烯和α-烯烴單體的共聚物,例如一種或多種上述的α-烯烴單體。適用於本案的VLDPE可具有0.87-0.915g/cm
3的密度。適用於本案的VLDPE可具有0.1-400g/10min、0.1-20g/10min或0.3-5g/10min的熔融指數。
在一些實施例中,乙烯類聚合物可以是HDPE。HDPE具有低分支度,因此具有更強的分子間作用力和抗張強度(tensile strength)。適用於本案的HDPE可具有0.941-0.965g/cm
3的密度。適用於本案的HDPE可具有0.1-400g/10min、0.5-65g/10min或1-30g/10min的熔融指數。
在一些具體實施例中,乙烯-乙酸乙烯酯聚合物可從USI Corporation購買,商品名為UE3312和UE629。適用於本案的乙烯-乙酸乙烯酯聚合物具有3-45重量%的乙酸乙烯酯含量(vinyl acetate content)和0.01-400g/10min的熔融指數。
在一些具體實施例中,聚烯烴彈性體可從陶氏化學(Dow Chemical)購買,商品名為ENGAGE™ 8003和ENGAGE™ 8180。適用於本案的聚烯烴彈性體可具有0.857g/cm

實驗例30
將100重量份的UE629、3.42重量份的H交聯劑和2.1重量份的DCP依次加入混合器(Brabender,型號:Plasti-Corder)中。加熱至120℃後,以35rpm的轉速繼續混合製程5分鐘,直至完全混合。然後將聚合物組合物冷卻至室溫。

實驗例36
將100重量份的UE659、3.42重量份的M交聯劑、2重量份的DCP、1.9重量份的BA和0.5重量份的ZnO依次加入混合器(Brabender,型號:Plasti-Corder)中。加熱至120℃後,以35 rpm的轉速繼續混合製程5分鐘,直到聚合物組合物完全混合。接著,將聚合物組合物置於模具中(厚度為0.3mm)並在2300psi下壓縮。使用液壓壓縮機(Carver,型號:Monarch 系列)進行加熱和壓縮。聚合物組合物在約175℃的溫度下放置在壓機中12分鐘。完成上述程序後,將聚合物組合物冷卻至室溫。
實驗例37及實驗例38
實驗例37和實驗例38以與實驗例36相同的方式進行,不同之處在於表9中列出的聚合物材料、交聯劑、自由基起始劑、發泡劑和添加劑的成分和含量代替了實驗例36中所使用的,以得到發泡產品。接下來,測量發泡產品的密度和泡孔尺寸。藉由電密度計(MIRAGE,型號:ED-120T)測量發泡材密度。藉由顯微鏡(Nikon,型號:ECCIPSE CI)檢查發泡材孔尺寸。最後,通過將發泡產品置於液壓壓縮機(Carver,型號:Monarch 系列)上的模具(厚度為0.4mm)中,在230℃的溫度和2300psi的壓力下加熱15分鐘以形成熱塑性回收材料,來檢查發泡產品的再加工性。
實驗例38中使用的聚合物材料為回收的UE659,其製備如下:將實驗例37的發泡產品切成小塊,並在230°C的溫度下以20rpm的轉速送入混合器中,然後以35rpm的轉速持續10分鐘。然後,將混合物冷卻至溫度以形成回收的UE659。

添加交聯劑製備的發泡產品(實驗例36、37)顯示出類似的發泡結構,其泡孔尺寸在100和220μm之間。此外,用回收聚合物材料製備的發泡產品(實驗例38)顯示出泡孔尺寸在200和300μm之間的發泡結構。實驗例36和實驗例37的發泡產品的密度在0.15g/cm
3-0.23g/cm
3的範圍,這是中底(midsole)的典型密度範圍。
此外,測量實驗例36和實驗例37的黃化指數(YI
發泡材(YI
foam))。YI
foam是通過光譜和目測確定的。藉由基於ASTM E313 [D65/10]的標準化方法使用色度計(HunterLab,型號:UltraScan VIS)確定黃化指數。YI是經過發泡和加熱回收後測定的。結果如表10所示。
表10
註:
YI

實驗例36 | 實驗例37 | 實驗例38 | |

YI reversed film(YI 回收薄膜) (厚度: 0.30mm) | 93.7 | 15.7 | 22.2 |
從表10所示的結果可以看出,與添加M交聯劑作為交聯劑的發泡產品(實驗例36)相比,添加H交聯劑作為交聯劑的發泡產品(實驗例37)顯示較佳的YI
foam,其回收材料顯示較佳的YI
reversed film。發泡產品和由其獲得的熱塑性回收材料的低黃化指數對於進一步應用的目的是更理想的。
在一些實施例中,以添加H交聯劑作為交聯劑的發泡產品(實驗例37)為例,發泡過程可以在170°C至195°C的溫度下進行6至15分鐘。發泡後測得的YI
foam在27-29之間。加熱回收後測得的YI
reversed film在15.5-17.5之間。
此外,值得注意的是,用回收聚合物材料製備的發泡產品(實驗例 38)也顯示出30.1的YI
foam,並且其回收材料顯示出22.2的YI
reversed film。這使得所得的發泡產品及其熱塑性回收材料具有理想的白色。
物理發泡製程
實驗例39
100重量份的UE659、3.42重量份的H交聯劑和2.0重量份的DCP依次加入混合器(Brabender,型號:Plasti-Corder)中。加熱至120℃後,以35rpm的轉速繼續混合製程5分鐘,直至完全混合。然後將所得物置於模具中(厚度為0.4mm)並在2300psi下壓縮。使用液壓壓縮機(Carver,型號:Monarch 系列)進行加熱和壓縮。將所得物在約175℃的溫度下壓縮15分鐘。完成上述程序後,將交聯的試樣冷卻至室溫。接著,將交聯的試樣放入超臨界流體發泡系統的槽中,將系統溫度調節到130℃以上(未達到熔融狀態)。然後將氮氣注入超臨界流體發泡系統並與交聯試樣混合。接著,將系統壓力調至150bar,使交聯試樣與氮氣超臨界流體形成單相溶液,並保持2小時。然後在1秒內將系統壓力調至1.013bar,得到發泡產品。
實驗例40
實驗例40以與實驗例39相同的方式進行,除了實驗例39中使用的聚合物材料是回收的UE659。接下來,測量發泡產品的密度、泡孔尺寸和黃化指數(YI
foam)。藉由電密度計(MIRAGE,型號:ED-120T)測量發泡材密度。藉由顯微鏡(Nikon,型號:ECCIPSE CI)檢查發泡材孔尺寸。最後,藉由將發泡產品置於液壓壓縮機(Carver,型號:Monarch 系列)上的模具(厚度為0.4mm)中,在230℃的溫度和2300psi 的壓力下加熱15分鐘,檢查發泡產品的可回收性。
實施例40中使用的聚合材料為回收的UE659,其製備如下:將實施例39的發泡產品切成小塊,並在230°C的溫度下以20rpm的轉速送入混合器中,然後以35rpm的轉速持續10分鐘。然後,將混合物冷卻至溫度以形成回收的UE659。

從表11所示的結果,值得注意的是,用回收的聚合物材料製備的發泡產品(實驗例40)顯示出27.3的YI
foam,而其回收材料顯示出40.5的YI
reversed film。YI值低於45可使所得發泡產品及其回收材料具有理想的白色。
實驗例39的發泡產品顯示出泡孔尺寸在100和150μm之間的發泡結構,而實驗例40的發泡產品具有在200和400μm之間的泡孔尺寸。實驗例39和實驗例40的發泡產品的密度在0.15g/cm
3-0.23g/cm
3的範圍,這是中底的典型密度範圍。
根據本揭露的一些實施例,當發泡材通過物理發泡製程形成時,可以使用超臨界流體或物理發泡劑進行發泡。超臨界流體可以是二氧化碳、氮氣或其組合。物理發泡劑可以是水、甲烷、乙烷、丁烷、丙烷、戊烷、己烷、乙烯、丙烯、甲醇、乙醇、丙酮、空氣或其組合。
在本揭露中,所得的可回收交聯聚合物發泡材在環境和經濟上是可持續的。在發泡製程中(如物理或化學發泡製程),通過應用特定類型的交聯劑(其中特別優選H交聯劑),並通過控制自由基起始劑、交聯劑和聚合物材料之間的特定比例,可實現理想的物理性能,例如聚合物及其回收材料意外的低黃化指數,這為可染色基材、鞋類、運動器材和家具等的進一步應用提供了靈活性。
雖然已經通過示例並根據較佳實施例描述了本揭露,但是應當理解,本揭露不限於此。相反,它旨在涵蓋各種修改和類似的配置(這對於本領域的技術人員來說是顯而易見的)。 因此,所附請求項的範圍應給予最廣泛的解釋,以涵蓋所有此類修改和類似配置。
