一种高缓冲伸缩双组份内饰棉及制备方法
技术领域
本发明涉及吸音棉制造技术领域，具体涉及一种高缓冲伸缩双组份内饰棉及制备方法。
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，各种各样吸音降噪的方法也随之诞生。而传统的吸音材料—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音效果，因此可以替代以离心玻璃棉为代表的传统多孔隔材料等，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音材料将会越来越多地得到市场的认可。
汽车内饰材料不仅是起到内饰作用，更应该起到较好的缓冲减压作用，这就要求汽车内饰材料不仅具有良好的强韧性，更要具备优良的弹性，汽车隔音棉作为内饰棉的一种，同样要求具有良好的伸缩弹性，才能起到优良的缓冲效果。

S4.组装：将弹性伸缩网层(2)通过网层连接永久磁体(5)和支撑架连接永久磁体(6)与弹性伸缩支撑架(1)磁性连接，固定凸条(8)上的大球形固定件(10)插入到连接凸条(9)上的大球形凹槽中、弹性伸缩网层(2)上的小球形固定件(11)插入到支撑连接加强筋(4)上的小球形凹槽，实现弹性伸缩网层(2)与弹性伸缩支撑架(1)的固定、连接；
S5.强化：将编织碳纤维层覆盖并包裹在弹性金属网架层(3)的外表面，将弹性金属网架层(3)插入到弹性伸缩支撑架(1)上对应开设的插孔中，并在弹性金属网架层(3)形成的网架空腔内部填装弹性伸缩多孔块件(18)，弹性伸缩多孔块件(18)由于其伸缩性卡在弹性金属网架层(3)形成的网架空腔中且其高度与弹性金属网架层(3)平齐，再次对隔音棉整体进行打磨、修边后即可。
