Description

一种建筑用隔音材料及其制备方法
技术领域
本发明涉及建筑材料技术领域，特别涉及一种建筑用隔音材料及其制备方法。
背景技术
传统的建筑混凝土是用水泥作胶凝材料，砂、石作集料，与水按一定配比搅拌成型，具有施工简便、强度高等特点被广泛应用，但随着用户需求的提高，对于建筑材料隔音性能的要求越来越高，隔音材料一般要求密度高、厚度大等，目前市场上的复合建筑材料密度较小，施工完成后隔音效果不明显，为了达到隔音的目的，往往通过在建筑物墙面加装隔音棉或隔音层实现，造价高，且增加了建筑施工难度。
隔音材料是指能够阻断声音传播或减弱透射声能的一类材料、构件或结构，其特征在于质量较重密度较高。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。因此，需要对现有的建筑隔音材料进行改进，以增强其吸音、隔音处理的效果，以减弱透射声能、阻挡声音的传播，并且在材料的环保及质量上进行改进，以达到一种环保轻质的建筑隔音材料满足建筑物声环境的保护需求。
