(1)将蜂窝芯层加热至30～40℃，将强化料均匀的涂抹在蜂窝芯层的表面，在30～40℃条件下干燥20～30min，常温冷却后，备用：
(2)将水泥二氧化硅微粉、河砂、鹅卵石粉、氢氧化铝、消泡剂和水混合，放入高速搅拌机中处理20～30min，放入立膜中成型，得面层；
(3)将步骤(1)处理后的蜂窝芯层与步骤(2)面层粘贴固定；
(4)将步骤3)得到的材料在30～40℃，湿度为80～90％条件下养护3～5d，再自然养护7天得到高强度隔音蜂窝纸墙板。
所述立模模腔尺寸为(2500～3000)mm×(400～500)mm×(70～80)mm。
有益效果

效果验证：试验组采用本发明方案制备的蜂窝纸墙板、对照组采用专利CN200510134265.1制备的复合隔墙板；制作的板材厚度均为90型；
空气声计权隔声量：采用GBJ75《建筑隔声测量规范》标准方法；
抗折破坏荷载：采用JG/T167-2005《建筑隔墙用轻质条板》标准测定；
含水率、气干面密度、干燥收缩值、抗冲击性和掉挂力军采用GB/T19631-2005《玻璃纤维增强水泥轻质多孔隔墙条板》标准测定；
试验组和对照组墙板的物理学性能如下表1：
由试验结果可知，试验组墙板的气干面密度高于标准要求，对照组的气干面密度低于标准要求；试验组和对照组的抗折破坏荷载均高于标准要求；而试验组抗折破坏荷载高出对照组0.6G；试验组的隔声量和对照组的隔声量均高于标准要求，试验组与对照组的隔声量相比，试验组高出11dB；试验组吊挂力高出对照组300N；通过以上参数可以得出，本发明方案制备的墙板性能优于对照组，特别是对墙板强度和隔音效果的提升。
