Abstract

La presente invencion se relaciona con una lámina de acero eléctrico no orientado revestido en ambas superficies con un revestimiento aislante paraconferir un alto nivel de resistividad superficial a fin de minimizar las pérdidas de potencia interlaminares. El revestimiento aislante curado sobre la láminade acero incluye, basándose en 100 partes por peso seco, 20-60 partes de fosfato de aluminio, 20-70 partes de por lo menos un silicato inorgánico en partículasy 10-25 partes de una resina acrílica. El revestimiento curado se forma a partir de una suspension ácida acuosa que puede incluir hasta 1 parte en peso de unsolvente orgánico hidrosoluble por cada parte de la resina. La suspension ácida acuosa tiene un pH de aproximadamente 2-2,5, untamano de partícula delsilicato de 0,3-60 microm, un tamano de partícula de la resina de menos de 1microm, menos de aproximadamente 0,5% en peso de áciso fosforico sin reaccionar yun peso específico de aproximadamente 1,0-1,3. El silicato puede consistir en uno o más del grupo que consiste en silicato de aluminio, silicato de aluminio ypotasio y silicato de magnesio. Después del curado, el revestimiento tiene un espesor en cada superficie de la lámina de 0,5-8microm. Los aceros eléctricos noorientados con revestimiento aislante se pueden utilizar para minimizar las pérdidas de potencia en los nucleos magnéticos laminados de motores, generadores,transformadores y otras piezas de equipamiento eléctrico.
