Description

一种吸音阻燃棉
技术领域
本发明涉及吸音棉材料技术领域，具体涉及一种吸音阻燃棉。
背景技术
噪声污染是人类生活环境的大公害，它不仅严重损害我们的听觉神经，心血管系统以及神经系统，并且还能加快建筑物、工业机械的老化，影响仪器的精密度和使用年限。随着大家对噪声控制问题的日益重视，各种各样吸声降噪的方法也随之诞生。而传统的吸声材料—玻璃棉因其存在着诸多缺陷，如降噪系数低、使用寿命短、不环保、容易造成二次污染等问题，其运用受到限制，已经淡出市场而为新型吸声材料所替代。纤维类吸声材料可以在较宽的频带内有良好的吸声效果，因此可以替代以离心玻璃棉为代表的传统多孔吸声材料等，这种同时具备环保、可重复利用、装饰功能、以及优越声学性能的吸声材料将会越来越多地得到市场的认可。
另一方面，随着生活实用和消防安全要求的日益增加，人们对于吸音棉的阻燃要求也越来越高。目前阻燃技术已进入一个新的发展阶段，未来吸音材料的阻燃技术正朝着高效、经济、环保的方向发展。由于无机阻燃剂具有：毒性低，热稳定性好；不析出，有持久的阻燃效果；不产生腐蚀性气体；价格低廉；较小的发烟量等优点，因此无机阻燃剂在各个方面的应用正逐步取代有机阻燃剂，因此合成无机阻燃剂的研究意义重大；但是由于有机阻燃剂目前仍在大量使用，将无机阻燃剂与有机阻燃剂组合使用不失为一种可取的过渡的方式。
目前，社会对吸音材料的需求量迅猛增长，传统的吸声材料已无法满足人们对环保性、装饰性、阻燃性的更高要求。因此，研究并开发应用新的环保吸音阻燃材料已成为努力的方向。
