所述的一种用于锅炉除尘的高效滤纸，所述乳化剂为丙烯醇聚醚、海藻酸钠和羧甲基纤维素钠的混合物。
所述的一种用于锅炉除尘的高效滤纸，所述乳化剂各组分的重量份数分别为：丙烯醇聚醚10-20份、海藻酸钠2-6份和羧甲基纤维素钠1-4份。
所述的一种用于锅炉除尘的高效滤纸，所述滤纸是通过以下步骤制得的：采用超声波分散器对聚酰胺纤维、玻璃纤维和竹纤维进行分散和疏解，再加入酚醛树脂、聚乙二醇、聚醚、聚硅氧烷、丙烯酸乳液、硬脂酸钾和环状糊精混合得到浆料，将浆料进行湿法抄造处理，最后经过压榨、干燥后得到滤纸。
本发明所达到的有益效果：
本发明的滤纸可以替代布袋除尘器中的布袋，制备简单，价格低廉，过滤效果好，通过加入玻璃纤维和竹纤维，使得滤纸的机械强度高，撕裂度高，通过加入酚醛树脂、聚乙二醇、聚醚、聚硅氧烷、丙烯酸乳液、硬脂酸钾和环状糊精，改善了浆料的分散性，提高了稳定性；本发明的丙烯酸乳液具有良好的稳定性，具有防水功效。
