Description

一种轨道交通用石墨烯改性粘胶基炭纤维吸声板制备方法
技术领域
本发明属于新材料领域，具体涉及一种耐腐蚀、抗老化、粘胶基炭纤维复合材料吸声板材。
背景技术
很多建筑物的刚性结构表面对声音的多次反射会造成内部空间声波相互干扰，增加室内噪声声压级，特别是在大空间建筑中，声反射的影响造成室内混响大，影响了正常的语言交流和听觉享受，在很多场合，如候车室，餐厅，音乐厅，酒吧、体育馆、录音播音室、会议室、报告厅、多功能礼堂、家庭影音室等需要对室内空间墙体表面做吸音处理，来达到降低噪音，消除混响等效果。传统吸音方法一般是包覆吸音棉，吸音板等材料，彩钢板行业也有吸音彩钢板的研发和销售。
吸音彩钢板的制造方法多种多样，究其原理都是通过涂层中的吸音成分或板体中的吸音结构将声波的能量吸收转化为热量，从而达到降低或消除声音的效果，但效果往往没有宣传的那样理想。作为吸音彩钢板，首先要解决的就是削弱反射声，目前吸音彩钢板尚不能很好的降低反射声；其次，当前吸音彩钢板中常用到的如玻璃纤维，空心玻璃微珠等吸音材料对高频声音吸收效果好，对中低频声音吸收效果偏差；再次，由于成本限制，难以通过增加吸音彩钢板中的吸音涂层厚度来提高吸音效果。
低密度炭纤维复合材料对各个频率的声音均具有优良的吸声效果，加速吸音效率，起到了隔声降噪的效果，同时还具有阻燃隔热的作用。
发明内容
本发明的目的是针对现有技术的不足，而提供一种工艺简单、硬化效果好、具有防水、防火、抗老化、抗冲击能力好，用材低能耗、环保、废弃后对环境无污染，在使用过程中，吸声效果好等优点的轨道交通用石墨烯改性粘胶基炭纤维复合材料吸声板的制备方法。
为了实现上述目的，本发明所采用的技术方案是：一种轨道交通用石墨烯改性粘胶基炭纤维复合材料吸声板的制备方法，其特征在于该方法包括以下步骤：

步骤四：将步骤三中浸渍处理后坯体置于固化炉内进行固化处理，固化温度为110℃-200℃。
步骤五：将步骤四中固化处理的坯体置于炭化炉内进行炭化处理，炭化温度为700℃-900℃。
步骤六：将步骤五出炉的粘胶基炭纤维复合材料坯体经过机械加工后，制得轨道交通用石墨烯改性粘胶基炭纤维复合材料吸声板。其最终密度为0.30 g/cm3-1.35 g/cm3。
上述的一种轨道交通用石墨烯改性粘胶基炭纤维复合材料吸声板的制备方法，其特征在于，步骤一中所述的粘胶基炭纤维丝束为1K-12K，炭纤维针刺体布针密度为10针/cm2-35针/cm2，炭纤维长度控制在5mm-100mm。
