随着传统石化能源的不可再生消耗以及汽车数量的剧增，促进了社会经济的发展和人类生活水平的提高，但是也让人类面临着严峻的能源紧缺和环境污染问题。为了提倡节能和环保，新能源汽车成为未来发展的主要方向。
新能源汽车数量增长的同时，相应的安全问题也日渐突出。由于高能化学物质的使用及能量集中等原因，高能电池的安全性能一直得不到圆满的解决，例如，锂离子电池在充电、放电或使用过程中，经常会由于受到挤压、碰撞或遇到其他意外情况而发生短路。当电池包内部发生热失控时，电芯内部剧烈的化学反应会放出大量热量、烟雾、气体，继而会发生爆炸，构成安全事故。因此如何提升电池包的安全性能，成为了首要的安全问题。

S2、接着设计电池壳，根据需求设置铺层方向；
S3、将一层一号防爆层当做内芯，二号防爆层预热后的一侧贴附在一号防爆层的上下两侧，随后再将阻燃层贴合在一号防爆层的另一侧；
S4、根据电池壳的阻燃防爆需求，重复S3的步骤，在上下方向上能进行一号防爆层、阻燃层和二号防爆层的顺序叠加；
S5、利用一体化热压成型工艺，对于铺设完成的阻燃层、一号防爆层和二号防爆层进行一体化成型。
与现有技术相比，本发明的有益效果是：
1.本发明利用纤维增强复合材料的低导热性，制成阻燃层，阻挡热量从材料表面向基体传递，同时隔绝氧气，起到了阻燃的作用。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1至图3，本发明提供一种技术方案：
一种阻燃防爆的新能源汽车电池壳，包括阻燃层1、一号防爆层2和二号防爆层；
阻燃层1的层数大于等于二，一号防爆层2的层数大于等于一，二号防爆层层数大于等于二；
一号防爆层2为内芯，阻燃层1固定在一号防爆层2的上下两端，且一号防爆层2与阻燃层1间隔排列，逐层铺放，能层层叠加；
一号防爆层2与阻燃层1之间通过二号防爆层进行贴合。
作为本发明的一种具体实施方式，
阻燃层1由纤维增强复合材料制成；
一号防爆层2由铝合金制成；
二号防爆层由胶粘剂制成。
一种阻燃防爆的新能源汽车电池壳的制备方法，包括以下步骤：
S1、首先选择制备电池壳的材料，包括由铝合金制成的一号防爆层2、由纤维增强复合材料制成的阻燃层1和由胶粘剂制成的二号防爆层；
S2、接着设计电池壳，根据需求设置铺层方向；
S3、将一层一号防爆层2当做内芯，二号防爆层预热后的一侧贴附在一号防爆层2的上下两侧，随后再将阻燃层1贴合在一号防爆层2的另一侧；
S4、根据电池壳的阻燃防爆需求，重复S3的步骤，在上下方向上能进行一号防爆层2、阻燃层1和二号防爆层的顺序叠加；
S5、利用一体化热压成型工艺，对于铺设完成的阻燃层1、一号防爆层2和二号防爆层进行一体化成型。
由铝合金制成的一号防爆层2、由纤维增强复合材料制成的阻燃层1和由胶粘剂制成的二号防爆层所制的电池壳，按照需求设置铺层方向是为了提高所需方向力学性能，在所需方向力上，能够承受更大的力，使其具有更大的抗压能力；
且能够根据具体的需求，例如强度和隔热性，进行具体的设计生产，能够适用不同的电池壳体的要求；
利用一体化热压成型工艺将铝合金、胶粘剂、纤维增强复合材料一次热压成型，减少加工工序，大大提高了生产效率；
由纤维增强复合材料制成的阻燃层1具有低导热性，可以阻挡热量从材料表面向基体内部传递，使得电池内部的材料的温度达不到燃点，同时各个界面可以很好的隔绝氧气，防止氧气进入电池内部，对电池内部的燃烧进行补充氧气过程，达到有效阻燃的目的，使电池壳体具有良好的阻燃性与燃烧自熄性。
由胶粘剂制成的二号防爆层，起到粘合作用，将阻燃层1和一号防爆层2贴合在一起，且胶粘剂具有一定的弹性，在受到冲击的同时变形，进而可以吸收冲击能量，防止裂纹延伸，提高防爆能力。
将阻燃层1、一号防爆层2和二号防爆层压制成型的电池壳具有轻质、强度高、抗疲劳性能好的特点，且具有优异的抗冲击吸能特性，在平台应力阶段能够吸收大量能量，在受到外界剧烈冲击或内部电池出现自燃、爆炸等异常情况时，通过内芯铝合金与胶粘剂层的变形吸收爆炸产生的动能与内能，减缓对车身内外的冲击，以至于壳体可吸收大量能量，保障车身内外安全，达到有效防爆的目的。
综上，在本实施例中，相比于现有技术，本发明的优点在于：利用纤维增强复合材料的低导热性，阻挡热量从材料表面向基体传递，同时隔绝氧气，起到了阻燃的作用，利用胶粘剂吸收能量防止裂纹延伸可以有效地进行防爆，利用一体化热压成型工艺将铝合金、胶粘剂、纤维增强复合材料一次热压成型，减少加工工序，大大提高了生产效率，利用压制的混杂层板变形吸收爆炸产生的动能与内能，起到有效防爆的作用。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
