Abstract
Disclosed is an insulating film composition of a non-oriented electrical steel sheet. The insulating film composition of a non-oriented electrical steel sheet according to the present invention comprises a mixed metal phosphate consisting of aluminum phosphate (Al(H3PO4)x=1-3) and cobalt phosphate (Co(H3PO4)3), and an organic/inorganic composite consisting of epoxy resin and silica (SiO2) nanoparticle substituted on the functional group of the epoxy resin.
