摘　　要：系统研究了无取向硅钢用磷酸盐系涂层性能的影响因素。以氢氧化铝和磷酸为原料制备磷酸二氢铝,再添加适量的添加剂酒石酸铵、二氧化硅、环氧树脂,得到的涂液涂布于硅钢表面,并控制合适的烘干温度,通过耐盐雾实验考察各因素对涂液耐腐蚀性能的影响。实验结果表明,在磷酸与氢氧化铝物质的量比为3.4∶1、酒石酸铵用量为2%、二氧化硅用量为1%、环氧树脂用量为5%、烘干温度为300℃条件下,所得涂层材料的防(耐)腐蚀效果最佳。The factors influencing the performance of phosphate anticorrosive coating for non-oriented silicon were systemati- cally studied.Aluminum dihydrogen phosphate was prepared with aluminum hydroxide and phosphoric acid as raw materials. Then added the right amount of additives, such as ammonium tartrate, silicon dioxide, and epoxy resin to prepare the liquid coating,which was coated on the surface of the silicon steel,and finally controlled a suitable drying temperature.The influ- ences of various factors on the anti-corrosion performance of the coating were investigated through the salt spray test.Experi- ment results showed that under the conditions of the amount-of-substance ratio of phosphoric acid to aluminium hydroxide of 3.4：1, ammonium tartrate dosage of 2%, silica dosage of 1%, epoxy resin of 5%, and drying temperature of 300 ℃,the coating material＇s corrosion prevention effect was the best.
