절연 피막 부착 전자 강판
摘要：
펀칭성및 밀착성이우수한절연피막부착전자강판을얻는다. 전자강판과당해전자강판상에형성된절연피막을구비하고,절연피막은 Si 및 Fe를포함하고, 절연피막에있어서의, Si의 SiO환산으로의부착량이전체부착량의 50∼99%이고, 절연피막에있어서의, Fe의함유량과 Si의함유량과의비(Fe/Si)가몰비로 0.01∼0.6인것을특징으로하는절연피막부착전자강판으로한다. 절연피막은유기수지및/또는윤활제를포함하고, 절연피막에있어서의, Fe의 FeO환산으로의부착량과 Si의 SiO환산으로의부착량의합계에대한유기수지및/또는윤활제의 C환산으로의부착량의비(C(유기수지+윤활제)/(FeO+SiO))가 0.05∼0.8인것이바람직하다.
摘要（英）：

The punching resistance and excellent adhesion to obtain an insulating film attached electrical steel.
An insulating film formed on the silicon steel sheet and the electronic steel sheet, and the insulating film containing Si and Fe, and is, in the insulating film, the adhesion amount of Si to SiO 2 in terms of 50~99% of the total coating weight, isolated the electrical steel sheet with an insulating film attached ratio of the content of, the content of Fe and Si in the film (Fe / Si) is from 0.01 to 0.6 characterized in that the ratio by mol. Insulating coatings of organic resins and / or lubricant to the sum of the coating weight to the SiO 2 in terms of the coating weight of a Fe 2 O 3 in terms of Fe and Si in the film containing an organic resin and / or a lubricant, and isolated C in terms of the adhesion amount of the non-(C (organic resin + lubricant) / (Fe 2 O 3 + SiO 2)) it is preferably from 0.05 to 0.8.
