Description

穿孔复合降噪板材
技术领域
本实用新型涉及聚氨酯、蜂窝类穿孔板复合板材。
背景技术
随着人们生活水平的不断提高,对所处声学环境要求也越来越高。目前,交通工具及高速公路、铁路、机械等所产生噪音对周围环境影响很大,解决的方法是用软质聚氨酯泡沫应用于型腔体内发泡吸音,吸音效果较好,但强度低没有装饰作用。
实用新型内容
本实用新型所要解决的技术问题是提供一种新型阻燃、环保的降噪复合板材,隔声和吸声能力强、降噪指标较好、强度高刚度好、易于安装、性价比高。
为解决上述技术问题,本实用新型提供一种穿孔复合降噪板材,其特征在于:穿孔板下面连接由蜂窝材和吸音材料复合而成的板材。
本实用新型穿孔板加蜂窝材及复合吸音结构组成的降噪复合板材,重量轻、同比强度高,提高保温、阻燃性能,吸音频率广,安装方便。
附图说明
附图是本实用新型的结构示意图。
具体实施方式
参照附图,1是穿孔板,2是蜂窝材,3是聚氨酯泡沫,蜂窝材和聚氨酯泡沫复合成一体,然后与穿孔板粘接。根据不同频率,通过调整穿孔板开孔率及穿孔板厚度,可实现客户要求的不同降噪效果。
