Abstract
(EN)
Through the present invention, by applying a coating having high insulating ability as a thin film, an electromagnetic steel sheet having low iron loss is obtained. In the present invention, an emulsion coating agent is produced in which an alkylalkoxysilane oligomer is dispersed in water using a surfactant and a small amount of an organic solvent, the emulsion coating agent is applied to an electromagnetic steel sheet, and a coating having high electrical resistance is formed on the surface of the electromagnetic steel sheet.

Grâce à la présente invention, en appliquant un revêtement présentant une capacité d'isolation élevée en tant que couche mince, une tôle d'acier électromagnétique présentant une faible perte dans le fer est obtenue. Dans la présente invention, un agent de revêtement en émulsion est produit, dans lequel un oligomère d'alkylalcoxysilane est dispersé dans de l'eau en faisant appel à un tensioactif et à une petite quantité d'un solvant organique, l'agent de revêtement en émulsion est appliqué sur une tôle d'acier électromagnétique, et un revêtement présentant une résistance électrique élevée est formé sur la surface de la tôle d'acier électromagnétique.
