[發明之效果]
本發明之熱塑性樹脂膜由於包含熱塑性樹脂、顏料、及受阻胺光穩定劑,故而能夠抑制對本發明之熱塑性樹脂膜照射光後產生色不均之情況。
以下詳細地說明本發明。
本發明之熱塑性樹脂膜(於本說明書中,有時簡稱為「樹脂膜」)係貼合於玻璃板等其他構件而適宜地使用。上述其他構件係貼合對象構件。
本發明之樹脂膜包含熱塑性樹脂、顏料、及受阻胺光穩定劑。
於本發明中,由於具備上述構成,故而能夠抑制於光照射後產生色不均之情況。本發明之樹脂膜之耐光性較高。本發明之樹脂膜於受到光照射後,緣部及緣部內側之色調不易變化,不易產生色不均。
本發明之樹脂膜係貼合於玻璃板而適宜地使用,適宜用於獲得含有玻璃板之積層體。於本發明中,可提高含有玻璃板之積層體之耐光性,而可抑制色不均之產生。
進而,於本發明中,由於採用上述構成,故而亦可抑制變色。於上述含有玻璃板之積層體具有較高之透明性之情形時,長期使用時或曝露於高溫下時可維持較高之透明性,而可防止可見光線透過率之降低。
上述樹脂膜可具有單層構造,亦可具有2層以上之構造,亦可具有3層以上之構造,亦可具有4層以上之構造。上述樹脂膜可具有2層以上之構造,而具備第1表面層與第2表面層。上述樹脂膜可具有3層以上之構造,而於上述第1表面層與上述第2表面層之間具備中間層。上述樹脂膜可具備2層以上之上述中間層。上述樹脂膜可具備第1中間層與第2中間層。
於依據JIS R3208之厚度2 mm之2片綠玻璃間夾入熱塑性樹脂膜而獲得含有玻璃板之積層體。該所獲得之含有玻璃板之積層體之全光線透過率較佳為1%以上,更佳為4%以上,又,較佳為50%以下,更佳為35%以下,進而較佳為20%以下,尤佳為10%以下。上述熱塑性樹脂膜較佳為具有滿足上述全光線透過率之下限或上限之區域。
就有效地抑制光照射後之色不均之觀點而言,上述表面層之全光線透過率較佳為高於上述中間層之全光線透過率。就有效地抑制光照射後之色不均之觀點而言,上述表面層之全光線透過率較佳為比上述中間層之全光線透過率高10%以上,更佳為高50%以上。
上述全光線透過率係平行光透過率與擴散光透過率之合計。上述全光線透過率係依據JIS R3106:1998而測定。具體而言,使用分光光度計,使測定對象物平行於積分球之開口部並與之密接,以使所透過之光線全部被積分球接收,從而測定分光透過率。上述全光線透過率意指根據於該狀態下測得之分光透過率所算出之可見光線透過率。作為上述分光光度計,例如可列舉日立高新技術公司製造之「U-4100」等。
以下,詳細地說明可用於本發明之樹脂膜的各材料。
(熱塑性樹脂)
上述樹脂膜包含熱塑性樹脂。作為上述熱塑性樹脂,可列舉:聚乙烯醇縮醛樹脂、離子聚合物樹脂、乙烯-乙酸乙烯酯共聚物樹脂、乙烯-丙烯酸共聚物樹脂、聚胺基甲酸酯樹脂、聚乙烯醇樹脂及環烯烴樹脂等。
於本發明之樹脂膜中,上述樹脂膜所含之熱塑性樹脂較佳為聚乙烯醇縮醛樹脂或離子聚合物樹脂,更佳為聚乙烯醇縮醛樹脂。上述表面層及上述中間層較佳為包含聚乙烯醇縮醛樹脂或離子聚合物樹脂。上述聚乙烯醇縮醛樹脂及上述離子聚合物樹脂分別可僅使用1種,亦可將2種以上併用。
上述聚乙烯醇縮醛樹脂例如可藉由利用醛將聚乙烯醇進行縮醛化而製造。上述聚乙烯醇縮醛樹脂較佳為聚乙烯醇之縮醛化物。上述聚乙烯醇例如可藉由將聚乙酸乙烯酯進行皂化而製造。上述聚乙烯醇之皂化度一般為70~99.9莫耳%之範圍內。
上述聚乙烯醇之平均聚合度較佳為200以上,更佳為500以上,又,較佳為3500以下,更佳為3000以下,進而較佳為2500以下。若上述平均聚合度為上述下限以上,則含有玻璃板之積層體之耐貫通性進一步提高。若上述平均聚合度為上述上限以下,則樹脂膜之成形變得容易。
上述聚乙烯醇之平均聚合度可依據JIS K6726「聚乙烯醇試驗方法」之方法而求出。
上述聚乙烯醇縮醛樹脂所含之縮醛基之碳數並無特別限定。製造上述聚乙烯醇縮醛樹脂時使用之醛並無特別限定。上述聚乙烯醇縮醛樹脂中之縮醛基之碳數較佳為3或4。若上述聚乙烯醇縮醛樹脂中之縮醛基之碳數為3以上,則樹脂膜之玻璃轉移溫度充分降低。
上述醛並無特別限定。一般而言,適宜使用碳數為1~10之醛。作為上述碳數為1~10之醛,例如可列舉:甲醛、乙醛、丙醛、正丁醛、異丁醛、正戊醛、2-乙基丁醛、正己醛、正辛醛、正壬醛、正癸醛及苯甲醛等。較佳為丙醛、正丁醛、異丁醛、正己醛或正戊醛,更佳為丙醛、正丁醛或異丁醛,進而較佳為正丁醛。上述醛可僅使用1種,亦可將2種以上併用。
上述聚乙烯醇縮醛樹脂之羥基之含有率(羥基量)較佳為15莫耳%以上,更佳為18莫耳%以上,又,較佳為40莫耳%以下,更佳為35莫耳%以下。若上述羥基之含有率為上述下限以上,則樹脂膜之接著力進一步提高。又,若上述羥基之含有率為上述上限以下,則樹脂膜之柔軟性提高,樹脂膜變得易於操作。
上述聚乙烯醇縮醛樹脂之羥基之含有率係將用羥基所鍵結之伸乙基量除以主鏈之伸乙基總量所求出之莫耳分率以百分率表示之值。上述羥基所鍵結之伸乙基量例如可依據JIS K6728「聚乙烯醇縮丁醛試驗方法」而測定。
上述聚乙烯醇縮醛樹脂之乙醯化度(乙醯基量)較佳為0.1莫耳%以上,更佳為0.3莫耳%以上,進而較佳為0.5莫耳%以上,又,較佳為30莫耳%以下,更佳為25莫耳%以下,進而較佳為20莫耳%以下。若上述乙醯化度為上述下限以上,則聚乙烯醇縮醛樹脂與塑化劑之相溶性提高。若上述乙醯化度為上述上限以下,則樹脂膜及含有玻璃板之積層體之耐濕性提高。
上述乙醯化度係將用乙醯基所鍵結之伸乙基量除以主鏈之伸乙基總量所求出之莫耳分率以百分率表示之值。上述乙醯基所鍵結之伸乙基量例如可依據JIS K6728「聚乙烯醇縮丁醛試驗方法」而測定。
上述聚乙烯醇縮醛樹脂之縮醛化度(於聚乙烯醇縮丁醛樹脂之情形時為縮丁醛化度)較佳為60莫耳%以上,更佳為63莫耳%以上,又,較佳為85莫耳%以下,更佳為75莫耳%以下,進而較佳為70莫耳%以下。若上述縮醛化度為上述下限以上,則聚乙烯醇縮醛樹脂與塑化劑之相溶性提高。若上述縮醛化度為上述上限以下,則製造聚乙烯醇縮醛樹脂所需之反應時間縮短。
上述縮醛化度係藉由如下方式求出。首先,求出自主鏈之伸乙基總量減去羥基所鍵結之伸乙基量與乙醯基所鍵結之伸乙基量所得之值。用所獲得之值除以主鏈之伸乙基總量而求出莫耳分率。將該莫耳分率以百分率表示之值即為縮醛化度。

依據JIS R3106:1998,測定所獲得之層合玻璃之中間層之最厚部位的全光線透過率(TvD)。使用分光光度計(日立高新技術公司製造之「U-4100」),使所獲得之層合玻璃平行於積分球之開口部並與之密接,以使所透過之光線全部被積分球接收,從而測定分光透過率。將根據所獲得之上述分光透過率所算出之可見光線透過率設為全光線透過率。再者,關於實施例1~26及比較例1~2中獲得之層合玻璃,測定所獲得之層合玻璃之中間層之最厚部位的全光線透過率。
(3)光照射後之色不均之評價
針對實施例27~40及比較例3中獲得之縱15 cm×橫15 cm之層合玻璃,將層合玻璃之某一面作為光源側,於距離光源230 mm之位置設置層合玻璃。進而,以層合玻璃之四邊中之兩邊被光照射到且剩餘兩邊被固定框遮住光之方式進行設置。使用Suga Test Instruments公司製造之「H75」,將黑面板溫度設定為50℃、照射強度設定為70 W/m
2(波長300 nm~400 nm),於黑面板溫度50℃下照射光1000小時。藉由目視觀察,根據以下基準判定色不均。再者,圖3顯示有產生了色不均之層合玻璃。
再者,關於實施例1~26及比較例1~2中獲得之層合玻璃,由於熱塑性樹脂膜之中間層之厚度之差異,故而中間層於較厚側與較薄側色調不同。因此,不對中間層較厚側之一邊與中間層較薄側之一邊進行比較,以另外之兩邊中之一邊被光照射到且剩餘一邊被固定框遮住光之方式進行設置,比較色調之變化及色不均。
[光照射後之色不均之判定基準]
○:被光照射到之兩邊之緣部之色調與緣部之內側之距離緣部5 mm~25 mm之範圍之色調相同,未產生色不均
×:被光照射到之兩邊之緣部之色調不與緣部之內側之距離緣部5 mm~25 mm之範圍之色調相同,產生了色不均
(4)光照射後之變色
又,針對光照射前之層合玻璃與光照射後之層合玻璃,使用分光光度計(日立高新技術公司製造之「U-4100」),依據JIS K8781-4:2013,根據色差ΔE而求出放置前後之色調發生變化。再者,測定部位設為層合玻璃之中央部。藉由色差ΔE,根據以下基準判定變色。
[光照射後之色不均之判定基準]
○:ΔE為3以下
△:ΔE超過3且為10以下
×:ΔE超過10
詳細內容及結果示於下述表1~6。再者,於下述表1~6中,各層中之塑化劑之含量表示於各層中相對於聚乙烯醇縮醛樹脂100重量份之含量。又,於下述表1~6中,顏料、染料、受阻胺光穩定劑、紫外線遮斷劑及抗氧化劑之含量表示於各層100重量%中之含量。又,於下述表1~6中,Mg與K之合計含量(ppm)表示於各層中之濃度。
(5)顏料之鑑定
對熱塑性樹脂膜進行利用二氧化碳之超臨界萃取或利用有機溶劑之索氏萃取等後,藉由熱分解GC(Gas Chromatography,氣相層析法)、MALDI-TOF-MS(Matrix Assisted Laser Desorption Ionization Time of Flight Mass Spectrometry,基質輔助雷射脫附/游離-飛行時間-質譜法)、TOF-SIMS(Time Of Flight Secondary Ion Mass Spectrometry,飛行時間二次離子質譜法)、LC-MS(Liquid Chromatography Mass Spectrometry,液相層析質譜法)、GC-MS(Gas Chromatography Mass Spectrometry,氣相層析質譜法)、TEM-EDS(Transmission Electron Microscopy Energy-dispersive X-ray spectroscopy,穿透式電子顯微鏡-能量分散型X射線分析)、NMR(Nuclear Magnetic Resonance,核磁共振)對萃取後之熱塑性樹脂膜進行分析。又,使上述索氏萃取後之熱塑性樹脂膜溶解於溶劑,藉由再沈澱法等僅取出熱塑性樹脂後,蒸餾去除沈澱時所使用之溶劑而獲得著色成分,採用XRD(X ray diffraction,X射線繞射測定法)、NMR、MALDI-TOF-MS、TOF-SIMS、LC-MS、GC-MS、IR(Infrared Radiation,紅外輻射)法、UV-Vis(Ultraviolet Visible,紫外-可見光)分析等而鑑定所獲得之著色成分。於存在複數種顏料之情形時,藉由HPLC(High Performance Liquid Chromatography,高效液相層析法)或GPC(Gel Permeation Chromatography,凝膠滲透層析法)等進行分取。鑑定後之定量方法係採用使用HPLC之峰面積製作校準曲線進行鑑定之方法、或使用UV-Vis光譜製作校準曲線之方法。
