Description
技术领域
本发明属于汽车内饰技术领域,涉及一种汽车内饰复合材料。
背景技术
汽车内饰(Automotive Interior)主要是指汽车内部改装所用到的汽车产品,涉及到汽车内部的方方面面,比如汽车方向盘套、汽车坐垫,汽车脚垫、汽车香水、汽车挂件、内部摆件、收纳箱等等都是汽车内饰产品,同时车顶的复合材料也属于其中之一。
车顶的复合材料板材不光只有装饰作用,他们所涉及到的功能性、安全性、以及工程属性是非常丰富的。其中目前最为常见的三种汽车车身的内饰板材包括有抗倍特板(高端车)、冲孔铝塑板(中高端)和高密度板(低端车);其中抗倍特板虽然美观、高档,但存在密度大、成本奇高的问题;而冲孔铝塑板在中端车型上普遍使用,但存在密度大、环保性能差、使用过程中与周围型材摩擦产生异响等影响乘客直观感受的问题;高密度板同样存在密度大、环保性能差的问题,同时吸潮会发生霉变、腐烂,严重影响乘客体验,综合性都较差。
发明内容
本发明的目的在于提供一种汽车内饰复合材料,旨在解决综合性差的问题。
为解决上述技术问题,本发明提供了一种汽车内饰复合材料,包括基材层以及防护层,其中基材层与防护层之间的厚度比为6-8:1;
所述基材层按质量份计,包括有以下组分:
所述防护层按质量份计,包括有以下组分:
本发明进一步设置为,按质量份计,所述基材层中还添加有2-4份十溴二苯醚。
本发明进一步设置为,所述基材层的制作方法包括有:
S11,按质量份取聚丙烯纤维和玻璃纤维;
S12,对S11进行梳理;
S13,向梳理完成的聚丙烯纤维和玻璃纤维上撒膨胀石墨和碳酸镁;
S14,对聚丙烯纤维和玻璃纤维进行铺网和针刺;
S15,加压烘烤,形成基材层。
本发明进一步设置为,按质量份向所述S13中撒入十溴二苯醚。
本发明进一步设置为,所述S13中先将膨胀石墨碳酸镁和十溴二苯醚混合均匀后进行撒入。
本发明进一步设置为,所述碳酸氢钾和所述碳酸铝均位于所述牛皮纸与所述基材层之间。
本发明进一步设置为,所述防护层的制作方法包括有:
S21,按质量份取各原料;
S22,将酚醛树脂溶于醇溶液中;
S23,将碳酸氢钾和碳酸铝撒于平铺的牛皮纸上;
S24,将酚醛树脂和醇溶液浇于S23上;
S25,待醇溶液挥发完成后将基材层和防护层粘贴为一体。
本发明进一步设置为,所述醇溶液为甲醇或乙醇。
本发明进一步设置为,所述S25是在干燥的气氛中进行的。
本发明进一步设置为,所述碳酸氢钾和碳酸铝的摩尔比大于2。
与现有技术相比,本发明提供了一种汽车内饰复合材料,当该复合材料使用在汽车内饰中时,该复合材料是连接在汽车外壳的内壁上的,同时通常在复合材料的内壁上还会粘贴一层起到装饰作用的层,比如色纸,从而起到美观、缓冲等效果。
其中首先由于复合材料作为主要部分的基材层的材料主要是由聚丙烯纤维和玻璃纤维混纺后,热压而成的,因此其总体的密度较小,符合目前提倡的轻质以及减排的要求;同时通过针刺热压成型等方式加工使得基材层的整体性更强;而且在遭遇火灾的时候,膨胀石墨能够受热后可迅速发生体积膨胀,从而起到隔绝氧气的作用;在基材层中的十溴二苯醚受热产生的溴化氢气体也可以起到吸热以及向外流出,从而起到阻隔氧气的作用;
不仅如此,当火灾发生的时候,防护层也受到了高温的作用,在这个过程中首先碳酸氢钾吸热发生分解,并产生了二氧化碳气体和水汽,其中由于复合材料整体外部是汽车的铁皮外壳,因此这部分气体就都会停留在汽车外壳内,此时碳酸铝与水汽之间发生反应,也生成二氧化碳,其中二氧化碳具有隔绝氧气的作用,从而能够防止火灾进一步的发生;同时水汽在较高温度的条件下也与碳酸镁之间发生反应,并也生成二氧化碳,也就是说在整个过程中,复合材料都会释放出二氧化碳以及一定的水汽,因此能够起到隔绝氧气,并且二氧化碳以及水汽和溴化氢气体流动的方向也是热源的方向,因此可以很好且持久地阻隔氧气,并阻止火灾继续发生的情况,而且由于这些反应都是吸热反应,也可以在一定程度上阻止火灾的继续发生或发展的速度。
其中,碳酸氢钾和碳酸铝的摩尔比大于2,所以碳酸氢钾受热分解后产生的水汽能够满足碳酸铝进行反应,同时多余的水汽还可以与碳酸镁之间进行反应。
