Description
技术领域
本发明涉及汽车消音生产技术领域，具体涉及一种负离子汽车天窗顶棚吸音棉。
背景技术
汽车顶棚隔音垫是贴合于汽车金属顶棚内壁上的一种汽车内饰件，主要用于起隔音、隔热作用，由于汽车金属顶棚通常导热性较高且密度和刚性较大，因此不利于隔热和隔音，需要在内壁上贴合一层隔音隔热垫，从而为车内驾驶人员和乘客提供舒适的感受。
现有的汽车顶棚隔音垫主要由丙纶毡及同类混纺毡或聚氨酯软发泡橡胶制成，丙纶毡及同类混纺毡材料加工过程中需要大量使用化学胶粘剂，且容易受水和天气影响而发生霉变；而对于聚氨酯软发泡橡胶，其材料本身具有毒性，加工工艺需要通过化学反应，能耗较高，且该材料不可回收利用，容易造成环境污染，此外还有化学结构不稳定，易氧化分解，不具有阻燃性能，存在火灾隐患等缺点。
发明内容
为解决上述问题，本发明提出一种负离子汽车天窗顶棚吸音棉。
为实现本发明目的，采用的技术方案是：一种负离子汽车天窗顶棚吸音棉，所述负离子汽车天窗顶棚吸音棉包括复合纤维层、蜂窝层、填充粉、隔热层、周边魔术贴、抗震孔、第一抗震条和第二抗震条，所述负离子汽车天窗顶棚吸音棉的表层设计为复合纤维层，所述复合纤维层的内层设置为蜂窝层和隔热层，所述蜂窝层的内部蜂窝孔内填装有填充粉，所述蜂窝层和隔热层内部中央位置开设有抗震孔，所述抗震孔内安装有第一抗震条和第二抗震条。
所述复合纤维层的材质包括矿山石棉纤维30～40份、植物纤维50～60份、石蜡8～15份、聚乙二醇10～20份、紫外线吸收剂3～5份、分散剂2～4份、稳定剂1～3份、PVC树脂10～20份、橡胶油5～12份、XPE 10～20份、聚乳酸10～20份、N-苯基-N`-异丙基-对苯二胺5～10份和偶氮二甲酰胺5～8份。
优选的，所述复合纤维层、蜂窝层和隔热层的周边设计有圆边形的周边魔术贴，其中，周边魔术贴的有效宽度为0.5～1.2cm。
优选的，所述填充粉的材质包括电气石粉30～40份、珍珠粉10～20份、纳米氧化镁5～8份、纳米氧化铝5～8份、纳米四氧化三铁3～5份和纳米二氧化硅12～16份。
优选的，所述负离子汽车天窗顶棚吸音棉的制备方法为：
