为了实现上述目的，本发明的技术方案通过如下方式来实现的：
一种户外用电力广告牌，其包括底板，所述底板按照如下工艺制备而得：
步骤1）称取原料，步骤2）制备混合料1，步骤3）制备混合料2，步骤4）制备混合料3，步骤5）喷雾造粒，步骤6）压坯烧结。
具体地，所述底板按照如下工艺制备而得：
步骤1）称取原料：按照重量份称取氧化锶1-2份、氧化钡1-2份、氧化硼1-2份、氧化钾2-3份、二硫化钼2-3份、海藻酸钠2-3份、白石墨3-5份、聚乙烯醇4-7份、羟乙基纤维素4-7份、高岭土5-9份、玻璃纤维5-9份、水15-22份、石英砂20-30份、氮化硅20-30份、海泡石25-35份、氧化铝30-50份、碳化硅100-150份；
步骤2）制备混合料1：将白石墨、聚乙烯醇、羟乙基纤维素以及玻璃纤维加入到水中，200转/min搅拌15min，然后加热至50℃，保温5min，自然冷却至室温，得到混合料1；
步骤3）制备混合料2：将石英砂、氮化硅、海泡石、氧化铝以及碳化硅依次添加到球磨罐中，球磨至粒径为10-50微米，取出球磨料，置于离心搅拌机中，以200转/min的搅拌速度搅拌10分钟，得到混合料2；
步骤4）制备混合料3：将氧化锶、氧化钡、氧化硼、氧化钾、二硫化钼、海藻酸钠以及高岭土混合，300转/min搅拌10min，得到混合料3；
步骤5）喷雾造粒：将混合料1、混合料2以及混合料3混匀，进行喷雾造粒，喷雾造粒后的颗粒平均粒径为100-200微米；
步骤6）压坯烧结：将步骤5）所得物料置于模具中压制成坯，成型压力为10MPa，将成型后的坯体充分干燥，放入烧结炉中烧结，升温速率为10℃/分，烧结温度900℃，保温2小时，取出，冷却至室温，即得。
优选地，氧化锶、氧化钡、氧化硼、氧化钾、二硫化钼、海藻酸钠、白石墨、羟乙基纤维素以及高岭土的粒径均控制在10-50微米；玻璃纤维的直径为10-20微米，长度为30-50微米。
本发明标识牌的其他组件并不是本发明的发明点，具体设计可参照常规设计，此处并不一一赘述。
本发明还提供了一种高强度耐腐蚀的陶瓷板，具体制备方法同上。
本发明取得的有益效果主要包括：
本发明制备的陶瓷底板抗弯抗压强度大，硬度高，耐酸碱腐蚀，可用于户外用电力广告牌，前景广阔；本发明制备工艺简单有效，通过简单的操作步骤，即可获得理想的陶瓷板材料，节省了中间繁琐的流程步骤，更为环保简易；通过添加玻璃纤维等物料，提高了耐腐蚀性能；通过添加合适配伍的石英砂、氮化硅、氧化铝以及碳化硅，提高了陶瓷底板强度和硬度；本发明工艺条件温和，制备方法和生产工艺简单易操作，满足工业化大生产。
