优选的，所述非金属复合层由以下重量份的成分组成：聚乙烯30-36份，秸秆粉45-52份，脂类增塑剂5-7份，其他助剂2-4份。
优选的，所述其他助剂包括如下重量比的组分：环烷油1-2份，硬脂酸2-3份，云母粉1-2份。
优选的，所述蜂窝层内填充有吸音海绵。
优选的，所述上铝板为底部开口的槽型结构，所述下铝板与上铝板底部焊接。一种幕墙用隔音复合铝板的制备方法，其特征在于：包括如下步骤：
（1）按重量比取制备非金属复合层的各组分先投入至高混机中混合20-40分钟，温度设置为70-80℃，混匀完成后投入至已经预热完成的密炼机内，密炼时间为10-15分钟，温度为130-145℃，最后采用双螺杆挤出机挤出热切造粒定型，温度设置为120-150℃；
（2）取上铝板通过折弯机从而弯折成底部开口的槽型结构，将四周连接处进行焊接；
（3）取（1）制备定型好的非金属复合层，预热至60-65℃，一面涂覆上高分子粘结膜，再将涂覆有高分子粘结膜的一面与上铝板内面贴合压实；
（4）将尺寸匹配的蜂窝层放入，与非金属层贴合后，将上铝板四周与蜂窝层进行固定焊接，焊接完成后蜂窝层内放置入裁切好的吸音海绵；
