▎ 摘　　要

NOVELTY - Air gap glue comprises glue substrate, mixed functional material, solvent and additive, where the mixed functional material comprises microbeads, and magnetic particles and/or fillers, the particle size of microbeads (D1) is 5-600 mum, the particle size of magnetic particles (D2) is less than or equal to D1, the particle size of filler (D3) is less than or equal to D1, and the filler is material with thermal conductivity. USE - The air gap glue is useful in an electromagnetic device (claimed). ADVANTAGE - The air gap glue improves the precision of air gap control, and has improved thermal conductivity, magnetic permeability and magnetic shielding capability.
