Binder for nanocrystalline magnetic core and preparation method thereof

The invention relates to the technical field of electronic device packaging, in particular to a binder for a nanocrystalline magnetic core and a preparation method of the binder, and the binder comprises the following components in parts by weight: 80-100 parts of a modified epoxy acrylate crosslinking system, 23-35 parts of a filler, 3.5-5 parts of a photoinitiator, 7-8.5 parts of a nano supplement, 3-6 parts of a silane coupling agent and 1.5-5 parts of a surfactant. The adhesive disclosed by the invention takes epoxy acrylate as a basic raw material and has good biocompatibility, and the viscosity and insulativity of the adhesive are improved through specific modification and crosslinking; the composite carbon quantum dots are added to enhance the toughness, and the affinity between the carbon quantum dots and the magnetic powder is improved according to the dispersity of the carbon quantum dots, so that the microstructure of the nanocrystalline magnetic core is improved, and the magnetic performance of th
