Description
本発明は、パネルを貫通して透過される音の量を低減するために、多層ガラスパネルタイプの用途において使用することのできる、多層中間層を提供する。この効果は、一緒に単一の多層中間層にされている、2つ以上のポリマーシートにおいて可塑剤濃度の差異を維持することによって達成される。
本発明によれば、多層中間層(この中間層は、異なる可塑剤濃度を有する2つのポリマーシートを有する。)を、パネル中に組み込むことによって、驚くべきことに、多層ガラスパネルに優れた音響抑制特性が付与できることがわかった。本明細書全体を通して詳細に記述されているように、異なる可塑剤濃度を安定的に含有するように、ポリマーシートを配合することによって、多層ガラスパネルを貫通する音響透過が、例えば、関心のある周波数または周波数領域において2デシベルを超えて低減できることが発見された。さらに、3つのポリマーシート層を有する実施形態は、取り扱いが容易で、従来法における従来の中間層の直接の代替品として使用されるように配合できるので、本発明の中間層は、適用分野において使用されている製造方法にいかなる変更も加えることなく、多くの適用分野において有用であるはずである。例えば、自動車のフロントガラス分野では、完成したフロントガラスを形成するために使用される積層工程を変更することなく、本発明の中間層によって代替できる、従来のポリマー中間層を使用することを含み得る。
本明細書において使用される「ポリマーフィルム」は、性能強化層として機能する比較的薄い、剛性ポリマー層を意味する。ポリマーフィルムは、ポリマーフィルムがこれ自体で多層窓ガラス構造体に対して、必要な耐貫通性およびガラス保持特性を提供することはなく、赤外線吸収特性などの性能改善をもたらすという点で、本明細書において使用されるポリマーシートとは異なる。ポリ(エチレンテレフタレート)は、ポリマーフィルムとして最も普通に使用される。
本明細書において使用される「ポリマーシート」は、積層窓ガラスパネルに十分な耐貫通性およびガラス保持特性を付与する中間層として使用するのに、単独でまたは2層以上の層の積層状態において適している薄層に、適切ないずれかの方法によって形成される、いかなる熱可塑性ポリマー組成物をも意味する。可塑化ポリ(ビニルブチラール)は、ポリマーシートを形成するために最も一般に使用される。
3GEH(トリエチレングリコールジ−(2−エチルヘキサノエート))の様々な量を配合した、記録された残留ヒドロキシル含有量を有するポリ(ビニルブチラール)シートおよびこれらのシートの厚さを表1に列挙する。これらのシートは、本発明の中間層を構成するために使用するか、または参照パネルを製造するための従来の中間層として使用する。すべてのシートにおいて、残留アセテート含有量は無視することができ、1mol%未満である。
