- a low-emission film using two layers of Ag film for example, a first transparent dielectric film, an Ag film, a second transparent dielectric film, an Ag film, and a third transparent dielectric film are sequentially formed on a glass plate. Since the low radiation film has a high solar radiation shielding function, various solar radiation shielding members using the low radiation film have been studied.
- the solar radiation shielding member described above tends to improve the solar radiation shielding function as the total film thickness of the Ag film increases.
- the low emission film having two Ag films described above was appropriate from the balance between cost and required performance.

Abstract
Description
以下に本明細書の用語について説明する。
本明細書における「可視光線」は、波長380nm~780nmの範囲の光とする。また、本明細書における「日射遮蔽」とは、波長300nm~2500nmの範囲の光のエネルギーの透過を抑制することを指すものとする。
可視光線透過率、可視光線の透過色調、及び反射色調について、自記分光光度計(日立製作所製、U-4000)を用いて測定される値を採用する。また、反射色調については、低放射膜が形成されていない透明基材面側(透明基材としてガラス板を使用している際は、「ガラス面側」と記載することもある)と低放射膜が形成された膜面側についてそれぞれ算出するものとする。可視光線透過率は、JIS R3106(1998)に準拠する方法で算出するものとする。また、透過色調及び反射色調はJIS Z8781-4に準拠する方法で、CIE L*a*b*色空間のa*及びb*を算出するものとする。
ヘーズについては、ヘーズメーター(スガ試験機、HZ-V3)を用いて測定される値を採用する。また、ヘーズは、JIS K7136(2000)に記載された方法に沿って算出するものとする。
幾何学膜厚は、一般的に用いられる膜厚と同じ意味であり、単なる膜や層の厚みを示す。幾何学膜厚は、低放射膜と同様の成膜条件で作成した単層の膜厚と基材の搬送速度との積から、該単層を作製する際の成膜速度を求め、該成膜速度を用いて該当する層又は膜の膜厚を算出される値を採用する。
本明細書における「屈折率」は、波長550nmにおける値を指すものとする。また屈折率は、まず低放射膜と同様の条件で単層を作成し、得られた可視光線透過率と可視光線反射率(膜面)とを自記分光光度計(日立製作所製、U-4000)で測定し、得られた値から光学シミュレーション(Reflectance-transmittance法)で算出される値を採用する。
光学膜厚とは、幾何学膜厚と屈折率の積で表される値であり、低放射膜と同様の成膜条件で作成した単層の、波長550nmにおける屈折率と膜厚との積から算出される値を採用する。
本明細書における「低放射膜」は、透明基材上の膜全体を指すものとする。また、「膜」は1以上の層が積層されたものとし、「層」は境界によって区切られる最小単位であり、層を構成する成分は1種類でも複数種類でもよく、また層内の成分の分布は均一でも不均一でもよい。また、「透明基材上」等の「上」とは、透明基材と接触しても、他の任意の膜や層が介在しているものでもよい。一方で「直上」及び「直下」は、対象となる層や膜と接触し、他の任意の膜や層が介在しないことを示すものとする。また、例えば図1に示したような日射遮蔽部材において、ガラス板G側を「下」、保護層44側を「上」とし、図1の第1誘電体膜10における結晶性誘電体層13や第4誘電体膜40における保護層44のように、膜の中で最も上側にある層を「最上層」と記載することもある。
本明細書では、加熱工程を経て加工されたガラス板を「加工ガラス」と記載する。当該加工ガラスとしては、前述したように合わせガラス、曲げガラス、強化ガラス等が挙げられる。上記の「加熱工程」は、温度を特に限定するものではないが、例えば合わせガラスであれば90~150℃程度、曲げガラスや強化ガラスでは550~720℃程度で加熱を行う。また、日射遮蔽部材が加熱工程を経て加工される場合についても「加工ガラス」と記載する。なお、この時、日射遮蔽部材の透明基材はガラス板を用いるものとする。
本明細書における「耐熱性」は、低放射膜の耐熱性を示すものとする。本明細書の実施例において、低放射膜が形成された日射遮蔽部材を690~700℃で7分間加熱し、加熱後のヘーズが1.5%以下、及び目視での外観評価で低放射膜に欠陥の見られないものを「耐熱性あり」とした。また、好ましくは1.0%以下、更に好ましくは0.5%以下としてもよい。
本明細書では、SnドープZnOを「ZnSnO」と記載する。Znは結晶配列しやすい金属原子であり、酸化物であるZnOは結晶性の誘電体層となる。一方で、ZnO層にSnがドープされたZnSnOは、Snのドープ量が多くなるほど緻密な非結晶状態をとる割合が増え、層全体として非結晶な誘電体層となる。本明細書の「ZnSnO」は非結晶な誘電体層を指すものとする。また、非結晶のZnSnOを得る為には、Snのドープ量を多くする必要がある。例えば、Zn:Sn(重量比)を40:60~80:20としたZnSnターゲットと、酸素ガスを反応性ガスとして用いたスパッタリング成膜によって得る事が可能である。また、この時、得られる誘電体層の組成は(ZnO)x(SnO2)1-x(ただし、0<x<1)であると考えられるが、本明細書では簡単にZnSnOと記載する。
本明細書では、AlドープSi3N4を「SiAlN」と記載する。Si3N4は非結晶性の誘電体層であり、Si3N4層にAlがドープされたSiAlNも同様に非結晶性の誘電体層である。SiAlNは、例えばAlを1~15wt%ドープされたSiターゲットと、窒素ガスを反応性ガスとして用いて、スパッタリング成膜を行うことで得ることが可能である。SiAlNは誘電体全体に対してAlを1~10wt%含むものであり、誘電体の成分比に影響を与えない程度の含有量であることから、SiAlNは概ねSi:N=3:4だと考えられるが、本明細書では簡単にSiAlNと記載する。
本発明の日射遮蔽部材は、透明基材上に、順に、第1誘電体膜、第1金属膜、第2誘電体膜、第2金属膜、第3誘電体膜、第3金属膜、及び第4誘電体膜が積層された低放射膜を有する日射遮蔽部材において、該第1誘電体膜は、該透明基材の直上にケイ素及び窒素を含む誘電体層A、該誘電体層A上にチタン及び酸素を含む誘電体層Bを含み、該誘電体層Aの光学膜厚が12~86nmであり、該第1誘電体膜、該第2誘電体膜、及び第3誘電体膜は、最上層に結晶性誘電体層を有し、該結晶性誘電体層は、光学膜厚が5~54nmであり、該第1金属膜、該第2金属膜、及び該第3金属膜は、直下に該結晶性誘電体層を有するAg膜であることを特徴とする。
日射遮蔽部材55は、上記の第1誘電体膜10~第4誘電体膜40までの低放射膜50と、該低放射膜50が形成された透明基材とを指すものである。また、本発明は低放射膜50の耐熱性を向上させたものであり、加熱処理を行って前述した加工ガラスとして用いることが可能である。
透明基材は低放射膜50を形成する板状の基材であり、本明細書においては、「透明基材」を厚み2mmにおける可視光線透過率が80%以上となる基材としてもよい。なお、図1では透明基材としてガラス板Gを用いているが、これに限定されるものではない。また、ガラス板Gは特に限定するものではなく、汎用的なフロート板ガラスや着色ガラス、化学強化ガラス、風冷強化ガラス等を用いても良い。
金属膜はAg膜であり、透明基材側から順に、第1金属膜1、第2金属膜2、及び第3金属膜3とする。金属膜の幾何学的膜厚の合計値を30~50nmとすることによって、良好な日射遮蔽性能とすることが可能であるため好ましい。上記膜厚の合計値が50nmを超えると、日射遮蔽性能は良好になるが、斜めから見た時の反射色に赤味を呈しやすくなる。また、30nm未満だと、日射遮蔽性能が不十分になりやすい。
上記の各金属膜は、直上に犠牲金属膜4を形成するのが好ましい。犠牲金属膜4は、金属膜の上に各誘電体膜を形成する際、露出した状態の金属膜の直上に各誘電体膜20、30、40を形成すると、該金属膜が酸素等により劣化してしまうことがあるため、この金属膜を保護する事を目的としたものである。犠牲金属膜4としては、加熱工程で著しい劣化の生じない材料を用いるのが好ましく、例えば、Ti、NiCr、Nb及びステンレス鋼からなる群から選ばれる少なくとも1つを含むものであることが好ましい。また、該犠牲金属膜4は最終的に酸化や窒化によって透明になるものを用いると、可視光線透過率を必要以上に損なわずに済むため好適である。なお、本明細書において、上記の「ステンレス鋼」とは、Fe、Cr、及びNiが混合したものであり、以下「SUS」と記載することもある。上記の3成分の含有量は適宜選択されればよいが、例えばFeを50~80wt%、Crを10~25wt%、Niを0~20wt%含有するとしてもよい。
第1誘電体膜10は、透明基材の直上に設けられる誘電体の膜であり、該第1誘電体膜10は、該透明基材の直上にケイ素及び窒素を含む誘電体層A11、該誘電体層A上にチタン及び酸素を含む誘電体層B12を含み、最上層に結晶性誘電体層13を有する膜である。膜厚は特に限定するものではないが、例えば光学膜厚で57~126nmの範囲内とするのが好ましい。
上記の誘電体層A11は、透明基材の表面に形成されるケイ素及び窒素を含む誘電体の層であり、特に透明基材としてガラス板Gを用いた際に、ガラス板Gのパッシベーション層として機能するものである。加熱環境下において、ガラス板Gからアルカリ金属等が誘電体膜内へ拡散し、該拡散成分が金属膜まで到達するとAgが劣化してしまうという問題がある。上記の誘電体層A11をガラス板Gの直上に用いると、本発明の実施例で示したように、690~700℃で加熱した場合であってもAgの劣化を抑制可能であることがわかった。当該誘電体層A11の材料としては、ケイ素を含む窒化物層、又はケイ素を含む酸窒化物層を用いるのが好ましく、例えばSi3N4、SiAlN、SiON、SiAlON等を用いるのが好ましい。
上記の誘電体層B12は、チタン及び酸素を含む誘電体の層であり、耐熱性を向上させる機能を有する。例えば、誘電体層B12としてTiO2を用いるのが好ましい。また、Tiに対してSi、Al、Zn、In、Sn、Nb、Zr又はTaを0.1~30wt%ドープしたTi酸化物を用いてもよい。
上記の結晶性誘電体層13は、第1金属膜1のAg膜の形成時にAgの結晶成長を促進させるものである。Agが結晶成長することによって、各種光学特性をより向上させることが可能となる。また結晶性のよいAg膜は、焼成時に劣化の起因となりうる欠陥が少ないため、耐熱性が向上しやすい。
第2誘電体膜20は、第1金属膜1上に形成される誘電体膜であり、主に可視光線の透過率や反射率、反射色調等に影響を及ぼす。膜厚は所望の光学特性に応じて選択されればよく、特に限定するものではないが、例えば光学膜厚で144~190nmの範囲内とするのが好ましい。
前記第4誘電体膜40は、第3金属膜3上に形成される誘電体膜であり、主に耐熱性や透過色調、反射色調等に影響を及ぼす膜である。第4誘電体膜40は、前記第2誘電体膜20等と同様に、各金属膜の屈折率と異なる屈折率を有する誘電体を用いればよく、特に限定されるものではない。膜厚は所望の光学特性に応じて選択されればよく、特に限定するものではないが、例えば光学膜厚で38~123nmの範囲内とするのが好ましい。
本発明の日射遮蔽部材55の低放射膜50は、スパッタリング法、電子ビーム蒸着法やイオンプレーティング法等で形成することが可能である。また、生産性、均一性を確保しやすいという点でスパッタリング法が適している。以下にスパッタリング法を用いて形成する方法を記載する。なお、本発明は以下の製造方法に限定されるものではない。
本発明の日射遮蔽部材55は、加熱工程を経ても低放射膜50内のAg膜の著しい劣化を抑制可能であることから、合わせガラス、曲げガラス、及び強化ガラス等の加工ガラスとして好適に用いることができる。また、加熱工程の後も可視光線透過率を70%以上とすることが可能である為、得られる加工ガラスの視認性を大きく損なわないと考えられる。以下に本発明の好適な実施形態について記載する。なお、当該実施形態についての記載のうち、前述した「1:用語の説明」~「3:日射遮蔽部材の製造方法」と重複する内容については、記載を省略した。
以下に本発明の実施例及び比較例を示す。実施例及び比較例の低放射膜の構成を表1に示した。また、「ZnSnO-30」「ZnSnO-50」とは、それぞれSnを30wt%、50wt%ドープされたZnターゲットと、酸素ガスを反応性ガスとして用いて、スパッタリング成膜を行うことで得た非結晶性の誘電体層であることを示すものである。いずれも厚み2mmのソーダライムガラス上に、マグネトロンスパッタリング装置を用いて成膜を行った。なお、表に記載していないが、実施例1~24、及び比較例1~8は、各金属膜の直上にTiの犠牲金属膜を幾何学的膜厚で2.8nm、比較例9は金属膜上にTiの犠牲金属膜を幾何学的膜厚で5.5nm、それぞれ形成した。
上記の実施例及び比較例で得られた各日射遮蔽部材を、700℃に保持したマッフル炉中に入れ、7分経過後に取出し、大気中で室温まで徐冷した。徐冷後に取り出し、以下の方法で低放射膜の評価を行い、得られた結果を表3へ示した。
ヘーズメーター(スガ試験機、HZ-V3)を用いて、JIS K7136(2000)に記載された方法に沿ってヘーズ値を測定した。また、目視による膜面の外観評価を行い、結果を表3に記載した。なお、表3では、粒子状や線状の欠陥が目視確認出来る場合や、膜面に白いモヤ状の欠陥が見える場合は「×」、粒子状や線状の欠陥は見られないが可視光を照射すると薄くモヤ状の欠陥が見られる場合は「○」、前述したいずれの欠陥も確認できない場合は「◎」とした。
各日射遮蔽部材の可視光線透過率をJIS R3106(1998)に準拠する方法で測定した。また、透過光及び反射光(膜面反射、及びガラス面反射)について、JIS Z8781-4に準拠する方法で、CIE L*a*b*色空間のa*及びb*を算出した。なお、実施例17については、透過光の可視光線透過率、a*及びb*の測定を行わなかった。
実施例1~20、22~24及び比較例1~9で得られた日射遮蔽部材と、厚み0.76mmのPVB膜と、ソーダライムガラス板2mmとを用いて、図2に示したような合わせガラスを作製した。
