Description

隔音复合材料 技术领域
本发明涉及高分子复合材料技术领域一种隔音复合材料及其制备方法。
背景技术
当前,噪声已成为一种主要的环境污染,声环境问题越来越受到人们的关注和重视。选用适当的材料进行吸音和隔音处理是噪声控制工程中最常用、最基本的技术措施之一。材料吸音和材料隔音的区别在于,材料吸音着眼于声源一侧反射声能的大小,目标是反射声能要小;材料隔音着眼于入射声源另一侧的透射声能的大小,目标是透射声能要小。隔音是指通过某种物品把声音或噪音隔绝、隔断、分离等。材料一侧的入射声能与另一侧的透射声能相关的分贝数就是该材料的隔音量。对于隔音材料,要减弱透射声能,阻挡声音的传播,就不能如同吸音材料那样多孔、疏松、透气,相反它的材质应该是重而密实的。隔音量遵循质量定律原则,就是隔音材料的单位密集面密度越大,隔音量就越大,面密度与隔音量成正比关系。
隔音材料品类繁多,比较常见的有实心砖块、钢筋混凝土墙、木板、石膏板、铁板、隔音毡、纤维板等,但这些隔音材料通常具有环保性差或隔音性能不理想等弊病。
发明内容
本发明就是为了解决上述现有技术存在的问题而提供一种隔音复合材料及其制备方法。
本发明的目的通过以下技术方案来实现:
