Adhesive Coating Composition For Electrical Steel Sheet, Electrical Steel Sheet Laminate And Method For Manufacturing Electrical Steel Sheet Product
Abstract: An embodiment of the present invention provides: an adhesive coating composition enabling adherence (coupling) of an electrical steel sheet without using conventional coupling methods such as welding, clamping and interlocking; an electrical steel sheet laminate to which the same is applied; and a method for manufacturing the same. An adhesive coating composition for an electrical steel sheet, according to one embodiment of the present invention, comprises, on the basis of 100 wt% of total solids: 15 to 70 wt% of a first composition containing an organic resin and an organic/inorganic composite in which inorganic nano particles are substituted for an organic resin; 20 to 80 wt% of a second composition containing a metal phosphate and a phosphoric acid; and 1 to 10 wt% of a coupling agent. The coupling agent can comprises one or more of a silane-based coupling agent, a titanate-based coupling agent and an aluminate-based coupling agent.
