Abstract
本发明涉及一种汽车门专用包覆型发泡制振片及其制备方法，采用丁基橡胶作为复合阻尼基体材料，同时在铝合金骨架材料上注塑上EVA发泡材料。当汽车门专用包覆型发泡制振片贴在车门内经过烘烤车间，包覆发泡层进行发泡、固化与丁基胶复合阻尼材料共同作用实现车门制振吸音的效果。
Description
技术领域
本发明属于阻尼材料领域，涉及汽车用约束阻尼材料，由其是一种汽车门专用包覆型发泡制振片及其制备方法。
技术背景
目前汽车中的发泡吸音材料和橡胶阻尼材料已经被各大车厂广泛使用。因为在汽车行驶中车门振动产生噪音，汽车发泡吸音材料可以有效地减低车外噪声及气流对乘车人的干扰提高乘车人的乘坐舒服度。汽车发泡吸音材料的材质一般为树脂，经过电泳烘烤(140℃～160℃×20Min)发泡后发挥NVH作用。
阻尼材料是为了降低汽车行进中产生的震动而衍生出的一种材料，粘贴在车身相应位置后立即发挥作用无需加热，即贴即用。其原理为将汽车的震动势能经过阻尼材料转化为热能达到降低震动的目的。但目前市场上供应的阻尼材料一般为橡胶型，为了增加橡胶型阻尼片的阻尼系数广泛采用的方法为增加产品厚度，但厚度增加后会增加车身自重，造成油耗和排放量的上升，不能达到绿色环保的目的。
发明内容
因此，针对上述的问题，本发明提出一种汽车门专用包覆型发泡制振片及其制备方法，采用了发泡吸音材料与阻尼材料结合的体系结构，不仅可以吸收振动中产生的噪声而且增加了车门的阻尼效果，扩展了阻尼材料的应用范围。
本发明采用以下技术方案：
一种汽车门专用包覆型发泡制振片中的制振层，包括制振层与发泡层，其中，制振层的组分及重量份数为：
丁基橡胶100份、
碳黑40-60份、
聚异丁烯50-80份、
石油树脂50-60份、
石墨烯包覆空心玻璃微珠5-8份、
轻质碳酸钙150-180份、
环烷油6-15份。
发泡层的组分及重量份数为：
原料EVA树脂100份、发泡剂20-25份、酸性中和剂1-2份、交联剂1-3份、填充剂0.1-3份、酞青绿0.1-0.2份。
所述碳黑为N550炭黑。
所述聚异丁烯的分子量为1000-3000之间。
所述石油树脂为EScorez 1204、EScorez 1304、萜烯树脂、松香树脂的一种或两种的组合。
所述发泡剂为4,4’氧代双苯磺酰肼。
所述酸性中和剂为高活性氧化镁。
所述交联剂为阿克苏公司的交联剂过氧化二异丙苯。
所述填充剂剂为碳酸钙，滑石粉，微晶蜡一种或几种的组合。
所述一种汽车门专用包覆型发泡制振片中制振层的制备方法，包括：(1)将丁基橡胶在开炼机上塑化炼胶8-10min，温度为70-80℃；(2)将步骤(1)得到的丁基橡胶投入密炼机中，投入碳黑、轻质碳酸钙、石墨烯包覆空心玻璃微珠，在70-80℃下混炼5-8min，再加入聚异丁烯、石油树脂、环烷油，混炼5min，出料压片，得到片状制振层材料。
其中石墨烯包覆空心玻璃微珠制作方法如下：
将90～100份空心玻璃微珠和30～40份硅烷偶联剂KH-550加入高速搅拌机内，在90℃下高速搅拌进行混合，搅拌5min，然后缓慢加入含有2％环氧树脂和70％石墨烯悬浮溶液，持续在90℃加热条件下搅拌10min，搅拌后放入真空干燥箱中干燥,将干燥后得到石墨烯包覆空心玻璃微珠。
所述制作发泡层材料包括如下步骤：先将密炼机预热30min达到95℃再将EVA树脂放入密炼机中，待EVA树脂彻底熔融后依次加入发泡剂、酸性中和剂、填充剂、酞青绿进行初混炼，混炼均匀后加入交联剂继续混炼10min，然后通过造粒机造粒，混合过程及造粒温度控制95～100℃，得到颗粒状发泡层材料。
所述汽车门专用包覆型发泡制振片包括如下步骤：先将注塑机预热30min达到90℃，再将1mm厚的铝合金模具中固定，通过注塑机将颗粒状发泡层材料融化按照开口模具形状在骨架层铝合金板表面注塑成型。再通过压片机将片状制振层材料压入注塑成型的开口内与骨架铝合金板复合并在另一面贴上离型层离型纸。
所述汽车门专用包覆型发泡制振片的结构是发泡层直接包覆在骨架铝合金板表面并且发泡包覆层在注塑过程中在骨架铝合金板另一面留有注塑后的开口，开口内使制振材料与骨架铝合金板表面复合。
所述片状制振层厚度为2-3mm，包覆发泡层厚度为2-3mm，骨架层骨架层铝合金板厚度为1mm。
本发明的有益效果：
(1)本发明汽车门专用包覆型发泡制振片中制振层内的石墨烯包覆空心玻璃微珠，其表面均匀分散着石墨烯片具有较好的阻燃性能同时空心玻璃微珠本身具有轻质隔音的优点。石墨烯包覆空心玻璃微珠可以提高或改善材料的耐水性、抗压强度、收缩率和冲击强度。因此本发明提供的发泡制振片不仅在抗弯曲性能上有了明显的提高，在减振性能、耐老化性能、耐高低温性能上也有明显的改进。
(2)本发明汽车门专用包覆型发泡制振片的结构是发泡层直接包覆在铝合金表面并且发泡包覆层在注塑过程中在铝合金另一面留有开口，在开口内制振材料与铝合金表面复合。当汽车经过烘烤车间后制振材部分牢牢的贴在车门内部，骨架层铝合金板周围的发泡层进行发泡将粘合车门板并且将骨架层铝合金板完全包覆。发泡后的双层阻尼结构当振动机械能经过制振层和发泡层后转变为热能而使振动减弱，再经过骨架层铝合金板和骨架层铝合金板背面的发泡层后机械能二次变为热能。这种结构有效减弱振动机械能的传播。
(3)本发明汽车门专用包覆型发泡制振片在受到外力振动弯曲变形时，迫使得复合阻尼层材料发生剪切变形，机械能转化为热能散发到空气中，具有较好的减震降噪效果。阻尼材料本身的质量和刚度有较小的改变，同时又有较高的安全性和可靠性。
