Description

一种隔音材料
技术领域
本发明涉及隔音技术领域，具体涉及一种隔音材料。
背景技术
随着汽车新四化和新能源化，对汽车的轻量化和舒适性要求越来越高，零部件的吸隔音和气味VOC的要求与越来越高。目前传统汽车前围内隔音采用重制层EVA+软层PU发泡或者其他软硬毛毡等方案，采用之前传统方案，EVA重制层3600kg/m2，克重比较高，产品比较重，一般达到7～8公斤左右，采用软硬层毛毡，隔音效果没有到达预期，在高频是，隔音系数在20左右，跟EVA相差盛远。轻量化和舒适性都未解决。
发明内容
本发明所要解决的技术问题是：现有的隔音材料重量较大，隔音效果不佳，无法同时兼具轻量化和良好隔音效果，本发明提供了解决上述问题的一种隔音材料。
本发明通过下述技术方案实现：
一种隔音材料，由上至下依次包括第一PET毡层、POE膜层和第二PET毡层；所述第一PET毡层的克重为1600g/m2-2000g/m2，第二PET毡层的克重为1000g/m2-1500g/m2；所述POE膜层采用改性POE膜制成，POE膜层的克重为100g/m2-200g/m2。
进一步优选，所述第一PET毡层的克重为1700g/m2-1900g/m2，第二PET毡层的克重为1100g/m2-1300g/m2，POE膜层的克重为130g/m2-180g/m2。
进一步优选，按重量份计，所述POE改性膜的材料包括POE颗粒100份，交联剂2-5份，偶联剂1-5份，发泡剂0.5-2份，抗氧化剂3-5份。
进一步优选，所述交联剂采用过氧化二异丙苯和α-α’双(叔丁基过氧化)-1,3-二异丙苯的混合交联剂，且两者配比依次对应为1:0.2～0.5。
进一步优选，所述偶联剂采用乙烯基三甲氧基硅烷。
进一步优选，所述发泡剂采用发泡剂AC、发泡剂H和助剂苯甲酸的混合物；且发泡剂AC、发泡剂H和助剂苯甲酸的质量配比依次为1:0.5～0.8:0.02～0.05。
进一步优选，所述抗氧化剂采用抗氧剂168。
一种隔音材料的制备方法，用于制备上述一种隔音材料，包括以下步骤：将第二PET毡层、POE膜层和第一PET毡层按照由下至上的顺序依次叠放作为预制层；将预制层在200℃～240℃温度条件下进行烘烤；烘烤结束后进行低温保压，最终获得隔音材料成品。
进一步优选，在200℃～240℃温度条件下进行烘烤50s～80s。
进一步优选，所述低温保压条件为：保压温度为20℃～25℃。
本发明具有如下的优点和有益效果：
目前，传统汽车前围内隔音采用重制层EVA+软层PU发泡或者其他软硬毛毡等方案，采用之前传统方案，EVA重制层3600kg/m2，克重比较高，产品比较重，一般达到7～8公斤左右，采用软硬层毛毡，隔音效果没有到达预期，在高频是，隔音系数在20左右，跟EVA相差盛远。
即目前都是采用重质层(如EVA重质层、POE重质层等)，只能通过增加隔音垫的厚度来提高整体吸音和隔音效果，这样势必就无法满足轻量化和舒适化需求。本发明通过对隔音材料各层材质的优化选择、各层材质的密度优化设计、以及采用改性的POE材质，最终获得隔音材料比重制层减半，大概3.5～4公斤左右，实现产品轻量化和舒适化需求，同时，隔音材料具有较好的隔音效果，隔音效果高频6300HZ，可以达到隔音系数35～40左右。
