本发明涉及环保涂料技术领域，尤其涉及一种外墙用多孔耐侯耐磨隔音涂料的制造方法。
 背景技术
现有技术中的隔音涂料，又称吸声涂层，一般是采用生物纤维、矿物纤维等为主要原料结合其他防火剂、防湿、防酶腐剂等，通过专业机械将之与粘胶剂一起喷出，附着于内屋面、墙面，形成2～10mm厚的表观具有多孔隙棉状涂层材料。

     ③静置底层涂料1-2天至涂料固结，出现疏孔和裂纹，然后在涂料表面均匀喷涂阶段1）步骤①准备的含根管藻孢子浓度1×10 6cfu/ml-1×10 8cfu/ml的海水，至底层涂料含水量升至30%-40%，然后持续喷水保持湿度至底层涂料及裂纹中的墙体表面完全覆盖生长出致密褐色苔，获得待处理底层涂料；
    ④采用明火烘烤涂料至涂料再次干结、褐色苔炭化，即获得所需底层涂料；
    3）表层涂覆
    ①将阶段1）步骤①准备的铝丝以1cm-5cm的网格间隙平铺在底层涂料表面，获得网格基材；
    ②将阶段1）步骤①准备的二氧化硅微粉、锆英石粉、金红石粉混合均匀后，与阶段2）步骤②获得的剩余70%湿热粘土再混合并搅拌均匀，获得功能石粉；
    ③将步骤②获得的功能石粉与阶段1）步骤②准备的适量水调配成湿度30%-35%的糊状物，将糊状物均匀涂抹在步骤①获得的网格基材表面，再在涂层外均匀喷涂阶段1）步骤①准备的硅酸溶胶，获得待处理涂层；
    4）涂料成型①将380V三相动力电源的三相电极分别施加在阶段3）获得的待处理涂层对应墙面的顶部两角和底部中间位置，保持2h-3h，即获得所需外墙用多孔耐侯耐磨隔音涂料。
  2. 一种外墙用多孔耐侯耐磨隔音涂料，其特征在于：该外墙用多孔耐侯耐磨隔音涂料由三层结构组成，底层为蒙脱石、高岭土按质量比（3-3.5）：（8-10）配比后混合网格状炭化纤维在电热脉冲下构成的深入墙体水泥的陶质结构；中层为二氧化硅微粉、锆英石粉、金红石粉、蒙脱石、高岭土按质量比（5-6）：（0.2-0.3）：（0.1-0.2）：（21-24.5）：（56-70）混合后经电热脉冲处理获得的类莫来石多孔陶质结构；表层为硅胶膜。
