Description
(一)、技术领域
本实用新型涉及一种专门用于防火、绝热、吸声要求的高层建筑、通风空调管道、空调机房各类泵房、车辆、船舶、飞机、制冷电器等保温保冷部位以及化工、医药、轻纺、冶金等行业各类冷热介质容器保温的无甲醛环保型保温吸音玻璃棉板；还可用于影剧院的舞台消音、保温、吸音降噪。其容重轻，优于其他保温、吸声材料，效果极其显著，而且有良好的回弹性；如在表面贴加铝箔防潮层，还可起反辐射及装饰作用；其施工方便、外观整洁美观，没有污染，是一种高品质环保型保温吸音材料。
(二)、背景技术
传统的保温、防火、隔音材料有聚苯乙烯、聚氨酯发泡、橡塑材料，虽具备轻便、耐热性好低温收缩性小，具有环保、节能功效，但其燃烧性能只能达到B级；相比较而言，玻璃棉保温材料更具有绝热性能好、抗压强度高、导热系数小、施工方便等优势。
一般的保温、吸音玻璃棉材料由超细玻璃棉施加酚醛树脂粘结剂、加温固化成型的成板状材料。保温吸音玻璃棉板的外保护层可以是铝箔纸或铝箔布，保温吸音层采用黄色(或黑色、或粉色)离心玻璃纤维棉板，玻璃纤维的平均直径为12～18μm。采用酚醛树脂作为主要粘结剂的保温吸音玻璃棉板，在玻璃棉中有游离甲醛、苯酚、尿素等有害物质存在，可长期在空气中释放低剂量甲醛，引起人体慢性呼吸道疾病、过敏刺激、极易出现肺功能异常、肝功能异常和免疫功能异常、嗅觉异常症状，甚至引发癌症，对于儿童孕妇的危害更大。
(三)、实用新型内容
本实用新型涉及一种专门用于防火、绝热、吸声要求的高层建筑、通风空调管道、空调机房各类泵房、车辆、船舶、飞机、制冷电器等保温保冷部位以及化工、医药、轻纺、冶金等行业各类冷热介质容器保温的无甲醛环保型保温吸音玻璃棉板；还可用于影剧院的舞台消音、保温、吸音降噪。
随着经济的发展，全球对能源的需求日益增大，建筑节能问题引起了越来越多的重视。实践证明，建筑节能最直接有效的方法是使用保温隔热材料。2009年央视大火，促使国家出台建筑节能领域的保温材料的防火性能技术要求与行政法规。防火成为建筑保温材料必须考虑的一个重要问题，保温隔热材料的燃烧性能越来越成为建筑材料选择的重要依据。
本实用新型不仅解决了保温吸音材料的燃烧性能问题；还解决消除了保温吸音玻璃棉中甲醛污染的技术环保问题；解决了保温吸音玻璃棉防辐射性能低的问题。
本实用新型的技术方案：保温、吸音玻璃棉为无甲醛环保型白色玻璃棉施加无甲醛粘结剂叠粘、加温固化成型的板状材料。白色，其容重轻、用于防火、绝热、吸声要求的高层建筑、通风空调管道、空调机房各类泵房、车辆、船舶、飞机、制冷电器等保温保冷部位以及化工、医药、轻纺、冶金等行业各类冷热介质容器保温的无甲醛环保型保温吸音玻璃棉板；还可用于影剧院的舞台消音、保温、吸音降噪。优于其他保温、吸声材料，效果极其显著。如在表面贴加铝箔防潮层，还可起反辐射及装饰作用；其施工方便、外观整洁美观，没有污染，是一种高品质环保型保温吸音材料。
本实用新型的技术特性：
1、容重32～48～64～80～96kg/m3
2、平均纤维直径：5～8μm
3、导热系数0.032～0.035W/m·k(20℃)依容重、厚度区别
4、平均吸声系数0.4～0.8，依容重、厚度、频率区别
5、防火性能达到GB8624不燃A级。
本实用新型具有以下优点：
(1)不含甲醛，在玻璃棉的安装使用后都不会释放甲醛，因而不会对人体健康造成伤害、不会对环境造成污染。
(2)不含氨、苯等有害物质，无味，无毒，保护人体健康，改变工作环境。
(3)隔热效果好，有效隔热，导热系数低。
(4)吸声效果好，可以减小内外墙体以及地板、天花板集合处的产音传输。
(5)无腐蚀性，不会造成对管道、金属件的腐蚀。
(6)耐用性好，不会腐烂、发霉，经久耐用。
(7)回弹性好，棉板经压缩包装后，仍能保持良好的厚度及回弹性。
(8)弹性好，粘结在一起的玻璃纤维在使用中不会分离，振动时不易脱落、断裂和松动。
(9)耐火性好，属A级不燃产品。
本实用新型采用无甲醛环保型丙烯酸类热固性粘结剂将细长的玻璃纤维粘结在一起，经加热加压制成的柔性板状的制品，不含氨、苯等有害物质，无味无毒，保护人体健康，改善工作环境。
