Abstract
Description
本発明に係る合わせガラス用中間膜は、熱可塑性樹脂と、可塑剤と、遮熱粒子と、フタロシアニン化合物、ナフタロシアニン化合物及びアントラシアニン化合物の内の少なくとも一種の成分と、黄色染料とを含有する。以下、フタロシアニン化合物、ナフタロシアニン化合物及びアントラシアニン化合物の内の少なくとも一種の成分を、成分Xと記載することがある。
本発明に係る合わせガラス用中間膜に含まれている上記熱可塑性樹脂は特に限定されない。上記熱可塑性樹脂として、従来公知の熱可塑性樹脂を用いることができる。上記熱可塑性樹脂は1種のみが用いられてもよく、2種以上が併用されてもよい。
本発明に係る合わせガラス用中間膜に含まれている上記可塑剤は特に限定されない。上記可塑剤として、従来公知の可塑剤を用いることができる。上記可塑剤は、1種のみが用いられてもよく、2種以上が併用されてもよい。
本発明に係る合わせガラス用中間膜は遮熱粒子を含む。該遮熱粒子は、金属の酸化物により形成された粒子であることが好ましい。遮熱粒子は1種のみが用いられてもよく、2種以上が併用されてもよい。
上記成分Xは、フタロシアニン化合物、ナフタロシアニン化合物及びアントラシアニン化合物の内の少なくとも一種の成分である。
本発明に係る合わせガラス用中間膜に含まれている黄色染料は、特に限定されない。黄色染料は1種のみが用いられてもよく、2種以上が併用されてもよい。黄色染料は、380〜500nmの透過光を効果的に吸収することが好ましく、390〜480nmの透過光を効果的に吸収することがより好ましく、395〜460nmの透過光を効果的に吸収することが更に好ましく、400〜450nmの透過光を効果的に吸収することが特に好ましい。この結果、上記遮熱粒子及び上記成分Xに加えて、黄色染料を用いることにより、上記Ttsをより一層低くすることができる。熱線の遮蔽性を充分に高めることができることから、黄色染料の極大吸収波長の好ましい下限は380nm、より好ましい下限は390nm、更に好ましい下限は395nm、特に好ましい下限は400nm、好ましい上限は500nm、より好ましい上限は480nm、更に好ましい上限は460nm、特に好ましい上限は450nmである。例えば、上記黄色染料の極大吸収波長は、トリエチレングリコールジ−2−エチルヘキサノエート(3GO)100重量部に対して、上記黄色染料0.01重量部を溶解させた溶液(セル長1mm、石英セル)を用いて、分光光度計(日立ハイテク社製「U−4100」)にて測定することができる。
本発明に係る合わせガラス用中間膜は、必要に応じて、紫外線吸収剤、酸化防止剤、光安定剤、難燃剤、帯電防止剤、顔料、染料、接着力調整剤、耐湿剤、蛍光増白剤及び赤外線吸収剤等の添加剤を含有していてもよい。本発明に係る合わせガラス用中間膜は、酸化防止剤を含有することが好ましい。本発明に係る合わせガラス用中間膜は、紫外線吸収剤を含有することが好ましい。
図1に、本発明の一実施形態に係る合わせガラス用中間膜を用いた合わせガラスの一例を模式的に断面図で示す。
(1)分散液の作製
トリエチレングリコールジ−2−エチルヘキサノエート(3GO)40重量部、ITO粒子(三菱マテリアル社製)0.28重量部、ナフタロシアニン化合物(富士フィルム社製「FF−IRSORB 203」)0.004重量部、及び、黄色染料(アンスラキノン染料、極大吸収波長450nm、チバ・ジャパン社製「ORACET Yellow GHS」)0.234重量部を混合し、さらに、分散剤としてリン酸エステル化合物を添加した後、水平型のマイクロビーズミルにて混合し、混合液を得た。その後、混合液にアセチルアセトン0.1重量部を撹拌下で添加し、分散液を作製した。分散液中のITO粒子の体積平均粒径は35nmであった。なお、ナフタロシアニン化合物(富士フィルム社製「FF−IRSORB 203」)は銅を含有している。
ポリビニルブチラール樹脂(ブチラール化度68.5モル%、水酸基の含有率30.5モル%)100重量部に対し、得られた分散液全量を添加し、ミキシングロールで充分に溶融混練した後、押出機を用いて押出して、厚み0.76mmの中間膜を得た。
得られた合わせガラス用中間膜を、その両端からJIS R3208に準拠した2枚の熱線吸収板ガラス(縦30cm×横30cm×厚さ2.0mm)で挟み込み、積層体を得た。この積層体をゴムバック内に入れ、2.6kPaの真空度で20分間脱気した後、脱気したままオーブン内に移し、更に90℃で30分間保持して真空プレスし、積層体を予備圧着した。オートクレーブ中で135℃及び圧力1.2MPaの条件で、仮圧着された積層体を20分間圧着し、合わせガラス1を得た。
合わせガラス用中間膜の組成を下記の表1に示すように変更したこと以外は、実施例1と同様にして、分散液、合わせガラス用中間膜、及び、合わせガラス1,2を作製した。
(1)Tts、及び、Tds(Solar Direct Transmittance)の測定
上記クールカー規制により定められた測定方法に従って、得られた合わせガラス1の上記Tts及び上記Tdsを測定した。具体的には、分光光度計(日立ハイテク社製「U−4100」)を用いて、JIS R3106(1998)に準拠して、上記Tts及び上記Tdsを測定した。
分光光度計(日立ハイテク社製「U−4100」)を用いて、JIS R3211(1998)に準拠して、得られた合わせガラス1の波長380〜780nmにおける上記可視光線透過率を測定した。
ヘーズメーター(東京電色社製「TC−HIIIDPK」)を用いて、JIS K6714に準拠して、得られた合わせガラス1のヘーズ値を測定した。
結果を下記の表1に示す。
なお、表1には合わせガラス1の測定結果を示しているが、合わせガラス2に関しても同様に、Ttsが低く、かつ可視光線透過率が高い合わせガラスを得ることができた。
