Abstract
【課題】射出成形によって窓ガラス板に枠体が成形され、枠体の射出成形と同時に枠体に固定される装飾モールであって、該装飾モールは射出成形時に外観不良が発生せず多色化に対応する。該多色対応装飾モールを有する枠体付き車両用窓ガラス板を提供する。 【解決手段】枠体が溶融樹脂の射出成形によってガラス板の周部に形成され、同時に装飾モールが枠体に固定される車両用窓ガラス板である。装飾モールの形状部材が、樹脂あるいは金属で形成され、該形状部材に、ポリ塩化ビニル系樹脂、アクリル系樹脂、ポリエステル系樹脂、ポリフッ化ビニリデン系樹脂から選ばれる１つ以上の樹脂で形成される樹脂フィルムが接合される。樹脂フィルムは顔料を用いて着色され、従って、装飾モールは枠体あるいは車体と同色になる。
Description
本発明は、射出成形で形成される枠体を周部に有する車両用窓ガラスに関し、特に、射出成形用金型のキャビティ空間にガラス板と装飾モールとを配置し、溶融樹脂をキャビティ空間に射出硬化して枠体をガラス板の周部に形成し、同時に装飾モールを枠体に固定して作製される枠体付き車両用窓ガラスに関する。
一般に電車や自動車等の車両の窓ガラス板は、金属製の車体に樹脂製の枠体を介して装着されている。
樹脂製の枠体は、流動性樹脂を押出成形あるいは射出成形により、ガラス板の周部に直接成形されている。これにより、枠体とガラス板とが一体となった枠体付きガラス板が車輌の組み立て用部品として用いられている。
さらに、枠体には装飾や補強のために、プレス成形や押し出し成形などで作製した細長い形状の装飾モールが接着剤などにより固定されることが多い。
特許文献１には、枠体を射出成形する際、射出成形用金型のキャビティ空間に装飾モ－ルを配置し、ガラス板の周部に、枠体および装飾モ－ルを一体的に固定する技術が示されている。
さらに、特許文献２には、枠体を射出成形する際、射出成型用金型のキャビティ空間に樹脂製あるいは金属製の装飾モールや補強材をインサート部品として配置し、枠体用溶融樹脂をキャビティ空間に射出硬化することにより、インサート部品を周部に一体的に有する枠体付き窓ガラス板が記載されている。
ところで、近年、車両ユーザーの嗜好により、装飾モールの色を車体や枠体と同色にするという傾向があり、装飾モールを多色化する必要が生じている。
特許文献３には、ロール成形で所定の形状に曲げられたＳＵＳ（ステンレス鋼）等の金属からなる金属ストリップに、接着層を介して着色層と透明樹脂層からなる装飾フィルムを接合し、さらにエッジ付近に弾性シール部材を設けてなる装飾モールが示されている。
前述したように、射出成形によってガラス板の周部に枠体を成形し、同時に装飾モールを枠体に固定する方法より枠体付き車両用窓ガラス板を作製する方法は、射出成形時に外観不良が発生し易いという問題があった。本発明では、射出成形時に外観不良が発生せず、なおかつ多色化に対応する装飾モールおよび枠体付き車両用窓ガラス板の提供を可能にすることを目的とした。
本発明の装飾モールは、枠体付き車輌用窓ガラスの枠体に固定される装飾モールであって、該装飾モールは、枠体が溶融樹脂の射出成形によってガラス板の周部に形成される時、同時に枠体に固定される物である。該装飾モールの形状部材は樹脂あるいは金属で形成され、枠体の表面から露出する装飾モールの形状部材の面には、ポリ塩化ビニル系樹脂、アクリル系樹脂、ポリエステル系樹脂、ポリフッ化ビニリデン系樹脂から選ばれる１つ以上の樹脂で形成される樹脂フィルムが接合されてなることを特徴とする装飾モールである。
また、本発明の装飾モールは、樹脂フィルムが、顔料を用いて着色され、枠体あるいは車体と同色になっていることを特徴とする装飾モールである。
また、本発明の枠体付き車両用窓ガラス板は、射出成形用金型に配置されるガラス板の周部に枠体を射出成型する際、前記金型のキャビティ空間に前記本発明による装飾モールを配置し、溶融状態の樹脂をキャビティ空間に射出硬化して枠体を成型する時、装飾モールが枠体に固定されることを特徴としている。
本発明によれば、射出成形時に外観不良が発生し難く、かつ多様な色に対応できる装飾モールが枠体に固定されてなる枠体付き車両用窓ガラス板の提供を可能にする。
本発明の装飾モールは、射出成形により周部に枠体を形成する車両用窓ガラス板に枠体と一体に固定されるものである。即ち、金型のキャビティ空間に装飾モールを配置し、枠体成形用溶融樹脂がキャビティ空間に射出硬化される時、装飾モールが枠体に固定されるものである。
本発明による装飾モール１０は、図１に示すように装飾モール１０の形状部材１２に樹脂フィルム１１が形成されているものである。
形状部材１２には、ポリエチレン樹脂、ポリプロピレン樹脂、エチレン－酢酸ビニル共重合体樹脂、ポリアミド樹脂、アクリル樹脂、塩化ビニリデン樹脂、ポリカーボネート樹脂などのプラスチック材料を押し出し成形、引抜法、射出成形などで成形されたものや、あるいは、ステンレス鋼、鉄、鋼、アルミニウムなどの金属材料を、プレス成形、押し出し成形、引抜法などで成形されたものを用いることができる。
樹脂フィルム１１は、形状部材１２にアクリル系、エポキシ系などの接着剤を用いて接合されるものであり、ポリ塩化ビニル系樹脂、アクリル系樹脂、ポリエステル系樹脂、ポリフッ化ビニリデン系樹脂等で出来ている。 これら樹脂フィルムは枠体の射出成形時の溶融樹脂の高温、高圧に対して変色・変形などの外観不良が生じにくい樹脂である。
さらに、樹脂フィルム１１は、着色顔料を樹脂に混入して、樹脂フィルム１１を着色させ、以って、装飾モール１０を枠体や車体の色と同色にすることができる。
着色顔料としては、特に限定しないが、酸化チタン、カーボンブラック、酸化鉄、紺青、群青などの無機顔料、アニリンブラック、バーミリオンレッド、レーキレッド、フタロシアニンブルー、ファストスカイブルーのような有機顔料が使用できる。
図２は、装飾モール１０が、ガラス板１５の枠体１４に固定されている枠体付き車両用窓ガラス板１を示している。
枠体１４を形成する樹脂には、スチレン系、オレフィン系、塩化ビニル系、ウレタン系等の熱可塑性エラストマーを用いる。
図３は、枠体付きガラス板を製造する際の、装飾モール１０の射出成型用金型２０のキャビティ空間への配置を示す。図示の様に、上金型（開閉型）１７と下金型（固定型）１８との間にはガラス板１５が配置される。この時、ガラス板１５の周部は枠体を形成する為のキャビティ空間１９内に位置する。
キャビティ空間１９に溶融樹脂が射出され硬化されて枠体が形成され、この時同時に枠体に装飾モール１０が固定される。
装飾モール１０の射出成形用金型２０への保持は、図示しない電磁石や押しピンなどで行う。溶融樹脂がキャビティ空間に射出され硬化されて、枠体が形成された後、上金型（開閉型）１７を上方に開いて、枠体が形成されたガラス板を取り出す。これにより、図２に示す本発明の枠体付き車両用窓ガラス１が製造される。
図３に示す例では、キャビティ空間１９の一部を形成する上金型（開閉型）１７に装飾モール１０を配置しているが、装飾モール１０は下金型（固定型）１８に配置してもよい。さらに図３のような上金型（開閉型）が上下に開閉する金型ではなく、開閉型が横開きする金型を用いてもよい。
以下、図面を参照しながら本発明を詳細に説明する。ただし本発明は次に説明する実施例に限定されるものではない。
図１に示す装飾モール１０は次のようにして作製した。
装飾モール１０の形状部材１２には、ステンレス鋼製の板をプレス成形したものを用いた。
形状部材１２に、ポリ塩化ビニルでなる厚み０．１ｍｍの樹脂フィルム１１を接着し装飾モール１０とした。
枠体を成形するガラス板１５には、厚み３ｍｍの板ガラスを所定の形状に曲げ加工した自動車用の窓ガラス板を用いた。
図３のように、上金型１７と下金型１８との間にガラス板１５を配置し、装飾モール１０が保持されているキャビティ空間１９に、塩化ビニル系の溶融樹脂を射出硬化して、図２の枠体付き車両用窓ガラス板を作製した。
なお、装飾モール１０の上金型１７への固定は、図示しない電磁石により行った。
本実施例で作製した装飾モール１０が固定されてなる枠体付き車両用窓ガラスは、装飾モール１０の表面に変形・変色等の外観不良が認められない、良好なものであった。
