Problems solved by technology

[0002] At home and abroad, pure iron powder and nickel powder are added to epoxy resin or silicone rubber resin as magnetic conductive materials to prepare magnetic composite materials with magnetic properties. The composite materials have magnetic conductive functions and are mainly used between magnetic materials or devices. There is no report on the method of using iron-based amorphous / nanocrystalline alloy powder as a magnetic material to prepare a magnetic adhesive

Embodiment 1

[0007] Fe78Si9B13 (composition is atomic percentage) amorphous alloy powder is selected, and the particle size is 320 mesh. The powder was heat-treated under argon protection (350°C, holding time 0.5 hours). The matrix resin material adopts: "epoxy resin E-51 type 50% + 650 type polyamide 50%", and at the same time, prepare to use acetone diluted resin material accounting for 20% of the total resin. Add the amorphous alloy powder to the acetone that is going to be used to dilute the resin, and add KH550 dispersant that accounts for 2% of the volume of acetone at the same time, stir and disperse until the dispersed particle size of the powder reaches 300 mesh (use a laser particle size analyzer to test the powder in the Particle size distribution in acetone), add resin material, fully stir in vacuum reactor (at 1.0*10 -1 pa pressure), it becomes glue / coating after being poured out of the reactor. In this glue, the alloy powder / resin mass ratio=5 / 1. It takes about 24 hours fo...
