本发明涉及涂层液技术领域,且公开了取向硅钢绝缘涂层液,其配比为:二氧化硅10‑15%、硼酸5‑8%、磷酸二氢盐2‑5%、金属溶胶20‑25%、氢氧化铝占5‑6%、有机酸处理的复合盐溶液20‑30%、分散剂0.5‑1%,其余为水,采用硅溶胶作为辅助成膜物,粘结力较强,对附着性影响很大。硅溶胶能够很均匀地包裹在被胶结物质的表面,通过自干成膜,保持了很高的常温结合强度;而磷酸盐涂层的固化是通过受热分解,脱水聚合完成的,低温强度差,中温强度高,充分利用了硅溶胶低温的结合强度和磷酸盐中、高温时的结合性能,消除了常规涂层烘烤时容易出现的收缩、起泡现象,阻止了微气孔的形成,提高了涂层的表面光滑度,粘结强度和稳定性同时保持绝缘涂层的光泽、光滑和稳定性。
