Abstract
Description
前記コア本体の外表面に設けられた発泡樹脂からなるクッション層と、
高屈折率層と低屈折率層とが交互に積層された反射ユニットを有する光反射膜、前記光反射膜の一方の最外層に粘着層、他方の最外層にハードコート層を有する光反射フィルムと、を有し、
当該光反射フィルムが、前記クッション層の外表面に巻き付けられていることを特徴とする光反射フィルムロール。
本形態の光反射フィルムロールは、円筒状に形成された、幅手方向の長さが1.2m以上のコア本体と、前記コア本体の外表面に設けられた発泡樹脂からなるクッション層と、高屈折率層と低屈折率層とが交互に積層された反射ユニットを有する光反射膜、前記光反射膜の一方の最外層に粘着層、他方の最外層にハードコート層を有する光反射フィルムと、を有し、当該光反射フィルムが、前記クッション層の外表面に巻き付けられていることを特徴とする。また、本形態の光反射フィルムロールは、さらに、前記光反射フィルムを巻きはじめる端部が、前記コア本体に設けられた前記クッション層にクッション部材で貼り付けられているのが好ましい。
本発明のコア本体11は、図1Aに示すように、円筒状に形成された、幅手方向の長さ(図1Aの符号Lの長さを指す)が1.2m以上のものであればよく、従来公知のものを適宜利用することができる。例えば、紙コア、樹脂を含浸させた紙コア、ガラスエポキシコア、プラスチックコア、金属(ステンレス)コア、等を用いることができる。好ましくは、軽量化(ロールツーロール方式で巻きつける際の稼働コストの低減や輸送コスト等の低減可能)、再生利用(リサイクル)が図れる紙コア、樹脂を含浸させた紙コア、プラスチックコア等を用いることが望ましい。なかでも安価で、軽量化、再生利用が図れ、環境(エコロジー)にもやさしい紙コアが望ましい。
コア本体11に光反射フィルム15を巻きつけると、コア本体11の表面と光反射フィルム15の巻きはじめの端部との間には段差が生じている。コア本体11の円筒状に形成された、幅手方向の長さが1.2m以上であると、コア本体11の両端を支持した場合に、コア本体11および光反射フィルム15の自重によって光反射フィルムロール1に撓みが生じる。この撓みによって、コア本体11に巻きつけられた光反射フィルム15のうち上記の段差の上に重なった部分に応力が加わって、光反射フィルム15に細かな欠陥が生じやすく、特に太陽光によるムラが視認されやすくなる。したがって、コア本体11の幅手方向の長さが1.2m以上のときに、太陽光によるムラの視認を低減できる効果が顕著である点で優れている。
コア本体11の円筒体の外径(コアのサイズ)としては、特に制限されるものではなく、具体的には、コア本体11の円筒体の外径5~150mmの範囲であるが、通常使用されている3インチコア(外径7.62mm)が好ましい。
本形態のクッション層12は、図1A、図1Bに示すように、前記コア本体11の外表面に設けられた発泡樹脂からなるものであればよく、従来公知の製造方法を適宜利用して作製することができる。例えば、コア本体を回転させながら、その外表面に発泡樹脂を一定の厚さで塗り付け、所定の外筒体の内部に所定の間隔(隙間)を持たせて、セットさせた後に発泡させるなどの方法が挙げられるが、これらの方法に何ら制限されるものではない。これにより、クッションコア14を形成させることができる。或いは、帯状に形成された発泡樹脂からなるクッションシートを、コア本体11の外表面に複数回巻き付けて、コア本体11の外表面に接着することで形成してもよい。このようにして、クッション層12において、互いに隣接するクッションシート間に位置する境界(巻き筋)が形成されている。クッションシートがコア本体11の中心軸に対して斜めに巻き付けられて、コア本体11の外表面に接着されている。この場合には、コア本体11の外表面またはクッションシートの内表面に接着剤を予め塗布しておくのがよい。なお、クッションシ層12は、コア本体11の外表面の全領域に亘って設けられるように、コア本体11の円筒状に形成された幅手方向の長さ(図中の符号L)とクッション層12の幅手方向の長さとが同じ長さになるように形成すればよい(図1A、図2A参照)。
クッション層12の形成に用いることのできる発泡樹脂としては、上記した作用効果(太陽光の照射により視認されるムラの低減ないし解消効果)を有効に発現し得るものであれば、特に制限されるものではい。具体的には、ポリエチレンの発泡体が好ましいが、これ以外にも、ポリウレタンの発泡体を用いることもできる。
本発明のクッションコア14は、図2Aに示す構成(クッション部材13を含まない場合もある)を有するものである。
本発明のクッションコア14の厚み(クッション部材13の厚みは除く)は、好ましくは1~20mm、より好ましくは3~10mmの範囲である。クッションコア14の厚さが上記範囲内であれば、上記した作用効果(太陽光の照射により視認されるムラの低減ないし解消効果)を有効に発現し得ることができる点で優れている。
本月名のクッションコア14に占めるクッション層12の比率は、全体のクッションコア14の厚み(クッション部材13の厚みは除く)に対して、10~50%が好ましく、20~40%が更に好ましい。クッションコア14に占めるクッション層12の比率が上記範囲内であれば、上記した作用効果(太陽光の照射により視認されるムラの低減ないし解消効果)を有効に発現し得ることができる点で特に優れている。
本発明のクッション部材13は、両面テープによって構成される。図2Aに示すように、クッション部材13の内側は前記コア本体11に設けられた前記クッション層12に貼り付けられている。また、クッション部材13の外側は、前記光反射フィルムの巻き始めの端部(巻付け端)が貼り付けられている構成となっている。かかる構成により、クッションコア14を形成させることができる。クッション部材13を用いることで、上記した作用効果(太陽光の照射により視認されるムラの低減ないし解消効果)を有効かつ効果的に発現し得ることができる点で優れている。さらに光反射フィルム15の巻き始めの端部とクッション層12との密着力が十分に得られる点でも優れている。特に、光反射フィルム15を巻き取るためにクッションコア14の回転を始動させたタイミングのときに、光反射フィルム15の巻き始めの端部の一部が、クッション部材13に貼り付けられていないと、クッションコア14から剥がれてしまう。その結果、折れ曲がったり、よれたり(めくれたり)する。このようなことを効果的に防止することができる点で優れている。かかる観点からは、光反射フィルム15の巻き始めの端部は、クッション部材13により貼り付けられていることが望ましい。但し、施工性等の観点から極僅かだけ、光反射フィルム15の巻き始めの端部がクッションコア14からはみ出す程度であれば、上記のような問題もなく尚且つ精密に位置合わせ操作を行う必要が無く、極めて合理的かつ生産的である。なお、クッション部材13の接着力に関しては、以下に説明するように、従来使用していた両面テープと同様の接着剤を用いてクッション部材13を構成することができるため、特に従来使用していた両面テープと同程度の接着力を有するものであれば、十分に使用可能である。
クッション部材13の厚さは、好ましくは50~200μm、より好ましくは60~150μmの範囲である。クッション部材13の厚さが上記範囲内であれば、上記した作用効果(太陽光の照射により視認されるムラの低減ないし解消効果)を有効に発現し得ることができる点で優れている。また、クッション層12の外表面及び光反射フィルム15の内表面にクッション部材13を確実に接着させることができる点でも優れている。
クッション部材13の構成としては特に制限されるものではなく、通常の両面テープの接着層/基材/接着層の構成において、基材と接着層との間にクッション層を設けた、接着層/クッション層/基材/接着層の構成としてもよい。或いは基材に代えてクッション層を用いることができる場合には、接着層/クッション層/接着層の構成としてもよいなど、特に制限されるものでない。クッション部材13については、製造してもよいし、市販されているものを用いてもよい。
クッション部材13は、クッション層12の外表面の幅方向全域に帯状に設けられるように、クッション層12の幅手方向の長さとクッション部材13の幅手方向の長さとが同じ長さ(図中の符号L)になるように配置すればよい(図2A参照)。但し、図2Aに示すクッション部材13の形状、幅手方向の長さ(符号L)及び配置は1例に過ぎず、例えば、クッション層12の外表面の幅手方向全域に帯状に配置するのではなく、ブロック状(三角形、四角形(長方形、正方形、菱形等)等の多角形状、円形状、楕円形状等)のクッション部材13を幅手方向全域に亘って点在するように配置してもよい。或いは、波状、網状、縦縞状(細長い帯状のラインのクッション部材13)を一定間隔をあけて幅手方向に複数配置した形態)、横縞状(細長い帯状のラインのクッション部材13)、不定形状を一定間隔をあけて幅手方向に垂直に複数配置した形態)のクッション部材13を幅手方向全域に亘って配置してもよいなど、制限されるものではない。クッション部材13の形状、配置としては、図2Aに示すように、クッション層12の外表面の幅手方向全域に帯状に設けるのが、巻き取る光反射フォルム15の幅手方向全域をクッション層12(クッション部材13)に貼りつけることが可能となり、光反射フィルム15がクッション層12(クッション部材13)から剥がれる問題を容易に解消することができる。
クッション部材13は、クッション層12の外表面の幅方向(幅手方向)に上記した各種配置(帯状等)にて、クッション層12の幅(幅手方向の長さ)Lとクッション部材13の幅(一方の端から他方の端までであって、ブロック状などの場合には途中空いてもよい)とが同じ長さLになるように配置すればよい(図2A参照)。クッション部材の幅(幅手方向の長さ)は、ロール幅Lと同じことが好ましいが、場合によっては幅方向において、数か所にわけてもよい。
クッション部材13の長さ(図2A中の符号dがクッション部材13の円筒形状に沿った長さである)は、好ましくは0.5~30cm、より好ましくは1~10cmの範囲である。クッション部材13の長さdが上記範囲内であれば、太陽光の照射により視認されるムラの解消効果を有効に発現し得ることができる。また、クッション層12の外表面及び光反射膜15の内表面にクッションテ部材13を確実に接着させることができる点でも優れている。
クッション部材13の粘着力は、従来の光反射フィルムロール1’で、用いていた両面テープ(図示せず)と同様の粘着力を有するものであればよく、特に制限されるものではない。これは、従来の両面テープ(図示せず)自体が、本発明のクッション部材13と同様に、その内側はコア本体11に両面テープで貼り付けられ、両面テープの外側は、前記光反射フィルムの巻き始めの端部を貼り付ける目的で使われていた為である。
本発明では、クッションコア14にクッション部材13を介して光反射フィルム15の巻き始めの端部を貼り付けた後、前記クッションコア14に前記光反射フィルム15をロール状に巻き付ければよいなど、特に制限されるものではない。例えば、ロールツーロール方式やラミネート方式など従来公知の巻き取り方法(ロール形成方法)を適宜利用して作製することができる。巻き終わったら、上記したように光反射フィルムロール1の巻き終りの端部(図1A中、符号Bの部分)をテープ20a、20b等で2か所以上(図1Aでは2か所止めの様子を表す)止めるのが好ましい。
光反射フィルムロール1では、光反射フィルム15の巻き終りの端部(図1A中、符号Bの部分)を2か所以上(図1Aでは2か所止めの様子を表す)、テープ20a、20b等で止めるのが好ましい。これは、従来の図1Cのようにテープ20cの1か所止めでは、光反射フィルムロール1’の巻き終りの端部がめくれあがり(図中の符号W参照)、施工時にカールが生じることから、図1Aに示すように、なるだけ光反射フィルムロール1の巻き終りの端部のめくれを防止し、施工時にカールがつかないようにできるためである。かかるテープ20a、20b等としては、跡が残らないテープであって、光反射フィルム15表面の構成成分を剥ぎ取らなければよく、特に制限されるのではないが、図1Cに示す従来の光反射フィルムロール1’で用いていたテープ20c(仮止め用の紙シール材であって、引き剥がす方向(図1A、Cの矢印参照)が印刷されたものなど)と同様のものを用いることができる。具体的には、紙基材の裏面に粘着層を有し、紙基材の表面に印刷が容易なように薄いフィルムが形成されていてもよい。粘着層については、例えば、光反射フィルム15の粘着層に用いた粘着剤等を適宜利用することができる。テープ20a、20b等の大きさも図1Cに示す従来の光反射フィルムロール1’で用いていたテープ20cと同様乃至同程度のものを用いることができる。具体的には、縦5~20cm×横2~5cm程度のものであれば、上記した作用効果を十分に奏することができる。
本発明の光反射フィルム15は、高屈折率層と低屈折率層とが交互に積層された反射ユニットを有する光反射膜、前記光反射膜の一方の最外層(内側)に粘着層、他方の最外層(外側)にハードコート層を有する。また、光反射フィルム15は、図1A、図1Bに示すように、前記クッション層12(更にはクッション部材13を含む)の外表面に巻き付けられている。本発明では、光反射フィルムロール1の光反射フィルム15に高屈折率層と低屈折率層とが交互に積層された反射ユニットを有する光反射膜を用いることで生じる固有の技術課題である、蛍光灯の照射では視認できないが太陽光の照射により視認されるムラを大幅に低減ないし解消することができる点にその特徴を奏するものである。光反射膜については、本出願人が既に多くの特許出願を行っており、多くが公開されており、その詳細については、既に公知となった本出願人の公報を適宜参照すれば作製することができるため、以下では、簡単に各構成を説明する。
基材上に屈折率を測定する対象層(高屈折率層、低屈折率層)をそれぞれ単層で塗設したサンプルを作製し、下記の方法に従って、各高屈折率層および低屈折率層の屈折率を求める。
光反射膜の形成にはバインダー樹脂を用いることができる。かかるバインダー樹脂は水溶性樹脂から構成されることが好ましい。水溶性樹脂としては、ポリビニルアルコール系樹脂、ゼラチン、セルロース類、増粘多糖類、反応性官能基を有するポリマー類が好ましいが、特にポリビニルアルコール系樹脂が好ましい。これらの水溶性樹脂は単独で用いても構わないし、2種類以上を混合して用いても構わない。
水溶性樹脂として用いられるポリビニアルアルコール系樹脂としては、重合度(平均重合度)が1500~7000であるのが好ましく、より好ましくは2000~6000である。
低屈折率層および/または高屈折率層は、金属酸化物粒子を被覆する水溶性樹脂を含有することが好ましい。以下に、金属酸化物粒子を被覆する水溶性樹脂について説明する。なお、当該水溶性樹脂は、金属酸化物粒子を溶媒に分散させやすくするための役割を有し、以下、「保護剤」と称する。
低屈折率層および/または高屈折率層は、硬化剤を含んでいてもよい。
高屈折率層および/または低屈折率層は、金属酸化物粒子を含有することが好ましい。
低屈折率層に用いられる第1の金属酸化物粒子としては、例えば、酸化亜鉛、合成非晶質シリカ、コロイダルシリカなどの二酸化ケイ素、アルミナ、コロイダルアルミナを挙げることができる。第1の金属酸化物粒子は1種であっても2種以上を併用してもよい。
高屈折率層は、第2の金属酸化物粒子を含むのが好ましい。高屈折率層に含まれうる第2の金属酸化物粒子は、低屈折率層とは異なる金属酸化物粒子であることが好ましい。
高屈折率層と低屈折率層には、必要に応じて各種の添加剤を含有させることができる。例えば、特開昭57-74193号公報、同57-87988号公報および同62-261476号公報に記載の紫外線吸収剤、特開昭57-74192号公報、同57-87989号公報、同60-72785号公報、同61-146591号公報、特開平1-95091号公報および同3-13376号公報等に記載されている退色防止剤、特開昭59-42993号公報、同59-52689号公報、同62-280069号公報、同61-242871号公報および特開平4-219266号公報等に記載されている蛍光増白剤、硫酸、リン酸、酢酸、クエン酸、水酸化ナトリウム、水酸化カリウム、炭酸カリウム等のpH調整剤、消泡剤、ジエチレングリコール等の潤滑剤、防腐剤、帯電防止剤、マット剤等の公知の各種添加剤を含有していてもよい。
粘着層は、光反射膜の一方の最外層に用いられる。光反射フィルムロールから巻き出した光反射フィルムを基体(ガラスなど)と貼り合わせるために用いられる粘着層は、光反射フィルムロールから巻き出した光反射フィルムを日光(熱線)入射面側に設置することが好ましい。また、光反射フィルムロール1から巻き出した光反射フィルムの粘着層を基体側に貼り付けて、窓ガラスと基体との間に光反射フィルムを挟持し、合わせガラスとすることもできる。さらに光反射フィルムロールから巻き出した光反射フィルムの粘着層を建物の窓や車のフロントガラスの外側(外貼り用)に貼り付けて設置してもよい。
HC層は、光反射膜の粘着層を設けた一方の側に対して他方の側の最外層に用いられる。HC層は、光反射フィルム表面の傷つきや汚れの付着の防止及び光反射フィルムを窓等に貼った時のカールバランスをはかる目的に設けられる。HC層の厚みは、0.05μm以上、10μm以下が好ましい。より好ましくは、1μm以上、10μm以下である。
光反射フィルムに必要に応じて用いられる基材としては、透明な有機材料で形成されたものであれば特に限定されるものではない。
光反射膜の製造方法について特に制限はなく、高屈折率層と低屈折率層とから構成される反射ユニットを有する光反射膜を形成することができるのであれば、いかなる方法でも用いられうる。これらの詳細については、本出願人が既に多くの特許出願を行っており、多くが公開されているため、その詳細については、既に公知となった本出願人の公報を適宜参照すれば作製することができる。
光反射フィルムロールから巻き出した光反射フィルムは、幅広い分野に応用することができる。例えば、建物の屋外の窓や自動車窓等長期間太陽光に晒らされる設備に貼り合せ、赤外遮蔽効果を付与する赤外遮蔽フィルム(近赤外反射フィルム)等の窓貼用フィルム、農業用ビニールハウス用フィルム等として、主として耐候性を高める目的で用いられる。
図3は、本発明の一実施形態に用いられる光学反射フィルムロール包装体21の基本的な構成を示す概略斜視図である。
チューブ状の袋22の材料としては、特に制限されるものではなく、従来の包装シートと同様の材料を用いることができる。具体的には、ポリエチレン等を用いることができるが、これらに何ら制限されるものではない。
チューブ状の袋22の形状は、円筒状の一方の端部が閉じており、もう一方の端部が開口しており、円筒部分の幅手方向の長さが、光反射フィルムロールの幅手方向の長さLよりも大きい形状であればよい。光反射フィルムロール1からはみ出したチューブ状の袋22の開口端部は、光反射フィルムロール1のコア本体11の円筒内の内側に押し込んで収納すればよい。なお、チューブ状の袋の両端を開口部として、光反射フィルムロール1をチューブ状の袋内部に収納後、チューブ状の袋のはみ出した両端とも光反射フィルムロール1のコア本体11の円筒内の内側に押し込んで収納してもよい。
チューブ状の袋22の円筒径の大きさは、光反射フィルムロール1をチューブ状の袋22に挿入し易く、更に上記した作用効果、特に、光反射フィルムロール1の表面のHC層とチューブ状の袋22との接触面が少なくなるように、光反射フィルムロール1の外径よりも大きければよい。
《低屈折率層用塗布液の調製》
はじめに低屈折率層用塗布液を調製した。具体的には、400部のコロイダルシリカ(10質量%)(スノーテックスOXS;日産化学工業株式会社製)、50部のホウ酸水溶液(30質量%)、300部のポリビニルアルコール(4質量%)(JP-45;重合度:4500、ケン化度:88mol%;日本酢ビ・ポバール株式会社製)、3部の界面活性剤(5質量%)(ソフタゾリンLSB-R;川研ファインケミカル株式会社製)、を45℃この順に添加した。そして、純水で100部に仕上げ、低屈折率層用塗布液を調製した。
次に高屈折率層用塗布液を調製した。具体的には、あらかじめシリカ変性酸化チタン粒子の分散液を調製した。これに溶媒等を添加した。
スライドホッパー塗布装置を用い、上記で得られた低屈折率層用塗布液および高屈折率層用塗布液を45℃に保温しながら、45℃に加温した基材(厚さ50μmのポリエチレンテレフタレートフィルム;東洋紡株式会社製、A4300)上に、18層同時重層塗布を行った。この際、最下層および最上層は低屈折率層とし、それ以外は低屈折率層および高屈折率層がそれぞれ交互に積層されるように設定した。塗布量については、乾燥時の膜厚が低屈折率層は各層150nm、高屈折率層は各層120nmになるように調節して基材上に光反射膜を形成した。
下記の処方で粘着層塗布液を作製した。
赤外線吸収剤としてATO(商品名:SR35M;ANP社製)を用い、紫外線硬化性樹脂として、ビームセット577(荒川化学工業株式会社製)を用い、溶媒としてメチルエチルケトンを添加した。さらに、フッ素系界面活性剤(商品面:フタージェント(登録商標)650A、株式会社ネオス製)を0.08質量%添加し、全固形分が40質量部、およびATOの添加量が全固形分に対して55質量%となるように調製して、ハードコート層用塗布液を作製した。
上記光反射膜の一方に粘着剤、反対側の最外層にハードコート層を形成した近赤外光反射フィルムを、多数のロールで搬送させながら乾燥を終了させ、クッションコア(コア本体:幅手方向の長さ1.5mの紙製の円筒体(3インチコア)、コア本体厚み;紙4mm+クッション層厚み;2mm)に巻き、膜厚100μm、幅手方向の長さ(幅)1.5m、長さ2000mの光反射フィルムロールを得た。この際、光反射フィルムの巻き取りの最後に、接着テープ(仮止め用の紙テープ乃至シール材、テープ幅2cm、長さ4cm)で、光反射フィルムの巻き終りの端部の幅手方向の中心部分(図1Cの符号Cの位置)を1か所止めて、光反射フィルムロールを得た。
実施例1からクッションコアに光反射フィルムロールの近赤外光反射フィルムの巻きはじめの端部をクッション部材であるクッションテープで固定した以外は同様にして作製して光反射フィルムロール包装体2を得た。
実施例2から、光反射フィルムの巻き取りの最後に、接着テープ(仮止め用の紙テープ乃至シール材、テープ幅2cm、長さ4cm)で、光反射フィルムの巻き終りの端部の幅手方向を2か所止めて、光反射フィルムロールを得たこと、更に得られた光反射フィルムロールを包装体としてのポリエチレンフィルムで包装後、接着テープで2か所止めたこと以外は同様にして作製して光反射フィルムロール包装体3を得た。
実施例3から、光反射フィルムロールを包装する際にポリエチレンフィルムではなく、チューブ状になったポリエチレン袋に光反射フィルムロールを入れて包装したこと以外は実施例3と同様にして作製して光反射フィルムロール包装体4を得た。
実施例1より、クッションコアではなく、紙コア(コア本体:幅1.5mの紙製の円筒体、厚み6mm、3インチコア(外径約7.62mm)のみで構成されたもの)を用いた以外は実施例1と同様にして作製して光反射フィルムロール包装体5を得た。
比較例1から、光反射フィルムを紙コアに固定する際に、実施例2で用いたクッションテープと同じクッションテープで紙コアに貼り付けた以外は比較例1と同様にして作製して光反射フィルムロール包装体6を得た。
