发明内容
本发明主要解决的技术问题是提供一种新型吸音降噪玻璃，能够在现有泡沫玻璃优异综合性能的基础上，解决其泡孔连通性差导致的吸音效果差的难题。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种新型吸音降噪玻璃，包括玻璃体，所述玻璃体上包括吸音层、吸音孔和吸音腔，所述吸音层位于所述玻璃体的中心位置，所述吸音腔对称分布在所述吸音层的两侧，且与所述吸音层连通，所述吸音孔均匀遍布在所述玻璃体的外表层，其一端与外界大气相同，另一端与所述吸音腔连通。
在本发明一个较佳实施例中，所述吸音层为一三层层压膜，其由环保阻尼吸音棉层、聚乙烯醇缩丁醛膜层和聚氯乙烯膜层依次复合而成。
在本发明一个较佳实施例中，所述吸音腔内含有占吸音腔体积30～50%的离心玻璃丝棉。
在本发明一个较佳实施例中，所述吸音腔的深度为所述玻璃体厚度为35～45%。
在本发明一个较佳实施例中，所述吸音孔的孔隙率为25～30%，孔径为0.2～0.3mm。
在本发明一个较佳实施例中，所述吸引孔为圆形孔、方形孔或椭圆形孔。
本发明的有益效果是：本发明一种新型吸音降噪玻璃的结构简单，设计合理，其通过相互连通的吸音孔、吸音腔和吸音层的设计，将大气与玻璃体内部连通，提升玻璃体内的空隙导通率，从而有效提升了玻璃体的整体吸音效率；并通过吸音腔、吸音孔的规格设计，及吸音腔填充物与吸音层的设计，提升了玻璃体的整体吸音性能，本发明的可以有效吸收环境中低、中、高频的声波，能够有效吸附环境中90～95%的噪音，具有高效吸音降噪的性能，市场前景广阔。
