摘要:
An electrical steel sheet adhesive coating composition according to an exemplary embodiment of the present invention includes, based on 100 wt % of the total solids: a resin at 20 to 40 wt % and having an average particle diameter of 10 to 300 nm; an inorganic nanoparticle at 10 to 35 wt % bonded with the resin; a metal phosphoric acid salt at 10 to 30 wt %; and phosphoric acid at 10 to 40 wt %.
An electrical steel sheet product according to an exemplary embodiment of the present invention includes a plurality of electrical steel sheets; and an adhesive layer disposed between the plurality of electrical steel sheets, wherein the adhesive layer includes a metal of one or more kinds among Al, Mg, Ca, Co, Zn, Zr, and Fe at 0.5 to 30 wt %, N at 0.1 to 10 wt %, C at 0.1 to 5 wt %, P at 1 to 30 wt %, a metal of one or more kinds among Si and Ti at 10 to 30 wt %, and a balance of O.
