技术领域
本发明涉及一种具有较高强度、弹性，又能抗氧化和耐腐蚀，还具有高绝热、吸音效果、经济耐用的吸音隔热膜。
背景技术
随着目前全球气候变暖，在低碳经济的大环境中，国家大力鼓励、推广节能减排，而输送管道吸音是非常重要一环。目前市场普遍使用的吸音材料主要为泡沫玻璃、岩棉等。泡沫玻璃本身导热系数较低，但其不足的是价格昂贵，不易施工，而且和管道内壁贴合不紧密，没有反射层，导致吸音效果受到影响；岩棉等材料既不具备反射功能，且不防潮容易氧化，吸音效果很差；为此，我们研发了一种具有较高强度、弹性，又能抗氧化和耐腐蚀，还具有高绝热、吸音效果、经济耐用的吸音隔热膜。
发明内容
本发明目的是为了克服现有技术的不足而提供一种具有较高强度、弹性，又能抗氧化和耐腐蚀，还具有高绝热、吸音效果、经济耐用的吸音隔热膜。

优选的，所述阻燃改性抗老化PVC层由EVA改性材料和改性抗老化PVC-ABS合金粒料制成，EVA改性材料与改性抗老化PVC-ABS合金粒料的质量比为1:10；所述阻燃改性抗老化PVC层的厚度为5-10毫米。 
优选的，所述改性聚乙烯气囊的空腔内充有空气，所述改性聚乙烯气囊层的高度为2-8毫米。

优选的，所述吸音纳米气凝胶泡棉的厚度为3-50毫米，所述纳米气凝胶胶体填充饱和率为40-49.3%，所述纳米气凝胶胶体的颗粒直径为60-79nm。
由于上述技术方案的运用，本发明与现有技术相比具有下列优点： 
本发明所述的吸音隔热膜中阻燃改性抗老化PVC层具有高强度、耐低温、韧性好的优点；同时铝箔绝热反射层具有高反射、耐低温、防潮的优点，使得本发明方案具有高吸音绝热、高强度、高减震、高耐低温、高防潮等优异性能。
