一种阻燃汽车内饰内衬无纺布，按重量份数计，包括：阻燃聚乙烯150份、聚氯三氟乙烯45份、6-己内酯5份、阻燃纤维30份、二氧化钛3份、聚乙二醇1份、水性聚氨酯110份、粘结剂0.4份、纳米级蒙脱土6份、甘油5份、玻璃鳞片4份和氯化镁7份。
一种阻燃汽车内饰内衬无纺布的制备工艺，包括如下步骤：
步骤1：取适量阻燃聚乙烯、聚氯三氟乙烯、6-己内酯、阻燃纤维、二氧化钛、聚乙二醇、水性聚氨酯、粘结剂、纳米级蒙脱土、甘油、玻璃鳞片和氯化镁；
步骤2：将步骤1选取的阻燃聚乙烯、聚氯三氟乙烯、6-己内酯、阻燃纤维、二氧化钛、粘结剂、纳米级蒙脱土、甘油、玻璃鳞片和氯化镁通过螺杆挤压喷射成网并通过热轧机花辊辊压成布；
步骤3：取聚乙二醇、甘油、水性聚氨酯与去离子水混合，然后喷涂在无纺布上，通过烘干机挤压成布并卷积成型，阻燃汽车内饰内衬无纺布制备完成。
综上所述，在本实施例中，按照本实施例的阻燃汽车内饰内衬无纺布及制备工艺，本实施例提供的阻燃汽车内饰内衬无纺布及制备工艺，由实施例1～实施例4可知，实施例3制备的阻燃汽车内饰内衬无纺布的阻燃效果最好，添加阻燃聚乙烯能够在传统聚乙烯的基础上增加阻燃的效果，同时添加纳米级蒙脱土和玻璃鳞片能够相互配合既能增加抗老化性和提高抗冲击性，纳米级蒙脱土和玻璃鳞片与粘结剂相互熔融能够增强阻燃聚乙烯的阻燃效果。
以上所述，仅为本发明进一步的实施例，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明所公开的范围内，根据本发明的技术方案及其构思加以等同替换或改变，都属于本发明的保护范围。
