Description

一种隔音材料
技术领域
本发明涉及一种复合隔音材料，属于建筑材料领域。
背景技术
音污染被看作是危害等同于大气污染、水污染的三大环境污染之一。一般噪声超过50分贝，就对人类日常工作生活产生有害影响，特别是对睡眠的影响。人类有近1/3的时间是在睡眠中度过的。睡眠是人类消除疲劳、恢复体力、维持健康的一个重要条件。但环境噪声会使人不能安眠或被惊醒，在这方面，老人和病人对噪声干扰更为敏感。当睡眠被干扰后，工作效率和健康都会受到影响，长期干扰睡眠会造成失眠、疲劳无力、记忆力衰退，以至产生神经衰弱症候群等。在居住环境中，层间噪音是最令住户苦恼的噪音来源。
为了减轻噪音影响装修时多使用隔音材料，现在市面上常见的隔音材料一般为水泥混凝土、玻璃板等，这些隔音材料的隔音效果并不是很好，并且这些隔音材料质量过重或厚度过大，安装不便。
发明内容
针对现有技术存在的不足，本发明的目的是提供一种隔音效果好、质量轻并且可以直接在墙面上安装的隔音材料。
为了达到上述目的，本发明提供的技术方案如下：
一种隔音材料，由第一隔音层、吸音层和第二隔音层组成，所述吸音层位于所述第一隔音层和所述第二隔音层中间；所述的一种隔音材料的制备方法为：在所述第二隔音层的一面涂上酚醛树脂后，将隔音层粘接在第二隔音层上，接着在第一隔音层凹凸不平的一面涂上酚醛树脂，按压到隔音层上；
所述第一隔音层由下列原料制成：聚乙烯、聚苯乙烯塑料、三元乙丙橡胶、钢渣粉、润湿剂、防水剂、抗氧剂；将各原料在高温下预混后，倒入模具中制成板材，且第一隔音层的内表面为凹凸不平的不规则曲面；所述吸音层由吸音棉、矿渣棉、玻璃纤维棉毡按体积比1∶1∶1组成。
进一步地，所述第一隔音层由下列重量份的原料制成：聚乙烯50～80份，聚苯乙烯塑料10～15份，三元乙丙橡胶10～15份，钢渣粉5～8份，润湿剂1～2份，防水剂5～8份，抗氧剂3～8份。
进一步地，所述第二隔音层为树脂薄板。
进一步地，所述第一隔音层和所述第二隔音层厚度均为5～8mm，所述吸音层厚度为8～20mm。
进一步地，所述第一隔音层、所述吸音层和所述第二隔音层之间使用酚醛树脂作为粘接剂。
本发明的有益效果：1、本发明的隔音材料共有三层，当声音传入第一隔音层时，声能一部分被反射，一部分会穿透材料，这部分声能由吸音层吸收，没有被吸音层吸收的声能再经过第三隔音层反射回吸音层被吸收，达到较好的隔音效果。
2、本发明的隔音材料中，第一隔音层为复合材料有较好的隔音效果的同时，质量较普通隔音材料来说更轻，第二隔音层优选树脂隔音材料质量也很轻，便于安装使用。
3、第一隔音层的内表面为不规则曲面，当第一隔音层和吸音层粘接到一起时，吸音层按第一隔音层的内表面形状填满曲面，增大了声能的反射路程，有效降低声能。
附图说明
图1为所述隔音材料的剖面图。
具体实施方式
参照图1对本发明的做进一步的详细描述。
