Abstract

The invention provides a coating for a Fe-based amorphous magnetically soft alloy strip, and a preparation method thereof. The coating has favorable working performance, and the advantages of small environmental pollution and low cost. The preparation method has a simple process and low production cost, and is suitable for industrial production. The coating for the alloy strip comprises the following components in percentage by weight: 20-30 percent of ethanol, 5-7 percent of dioctyl phthalate, 1-3 percent of n-butyl methacrylate, 25-30 percent of aluminium oxide / nano-zinc oxide composite material, 5-8 percent of gallic acid propyl ester, and the balance of polyurethane.

Description

technical field [0001] The invention belongs to the field of metal materials, and relates to a coating for an iron-based amorphous soft magnetic alloy strip and a preparation method thereof. Background technique [0002] Application No. 200710122020.6 proposes a soft magnetic alloy strip with a good electrical insulation coating on the surface and its preparation method, which is prepared by dip-coating at least one of inorganic suspension, inorganic solution and organic solution Liquid immersion coating of soft magnetic alloy strips, dipping the soft magnetic alloy strips in the dipping solution for 60s~600s; then baking at 90℃~250℃ for 60s~1200s, so that the thickness of the dipping coating reaches 0.5μm ~15μm; the soft magnetic alloy strip is wound into a magnetic core of the corresponding size, and annealing heat treatment is performed between 350°C and 600°C to become a soft magnetic alloy insulating strip with an electrically insulating coating. [0003] The inorganic...
