Abstract
The invention relates to a preparation method of a surface complexation film coated FeCuNbSiB strip, and belongs to the technical field of preparation of iron-based amorphous strips. The preparation method comprises the steps that walnut green seedcases are extracted; a tannin concentrated solution is collected and then subjected to esterification modification; a stable chelate can be formed by two adjacent phenolic hydroxyl groups in tannin and metal; and after a metal strip is exposed in air for a long time, tannin esterification matter is closely adsorbed to the surface of the strip by means of the water and oxidation corrosion function in air. The prepared surface complexation film coated FeCuNbSiB strip is high in durability; after the strip is placed at the room temperature for 6-8 months, epoxy resin wettability has no change; the combination degree of the strip and epoxy resin is high, and the service life is prolonged by 15%-20% relative to products of the same kind after combination with the epoxy resin; and the walnut green seedcases are used for preparation, and therefore the strip is green, safe and free of environment pollution.
Description
Technical field
The present invention relates to the preparation method of a kind of surface complexation overlay film FeCuNbSiB band, belong to Fe-based amorphous band system
Standby technical field.
Background technology
Compared with conventional soft magnetic materials MnZn ferrite, permalloy, Fe73.5Cu1Nb3Si13.5B9(being called for short FeCuNbSiB)
Nanocrystalline strip has high magnetic permeability (initial permeability can reach more than 80000, and maximum permeability can be more than 450000), height is satisfied
With advantages such as magnetic induction (Bs can reach 1.25T), low-coercivity, low iron loss and good thermal stabilities, it helps lend some impetus to
Miniaturization of electronic products, lighting, be widely used in sophisticated power transformer, high power switch current transformer, reactor,
Wave filter and other ultra-high frequency fields.FeCuNbSiB amorphous band is mainly obtained by liquid phase cooling method [7], its
Thermodynamically being in metastable state, soft magnet performance is poor.To improve the soft magnet performance of FeCuNbSiB amorphous band, it is right to need
FeCuNbSiB amorphous band carries out heat treatment, makes part non-product state be converted into crystalline state;But the FeCuNbSiB nanometer after heat treatment
Crystal zone material is more crisp and it is by under the effect of external carbuncle, and soft magnet performance can decline.In order to protect FeCuNbSiB nanocrystalline strip,
Production process needs FeCuNbSiB nanometer product band is carried out epoxy encapsulation.
FeCuNbSiB nanocrystalline strip surface is in amorphous/nanocrystalline state, there is substantial amounts of defect, FeCuNbSiB nanometer
There is substantial amounts of periodicity stomatal band and a rule obvious cold shut lines in brilliant strip surface, the existence of these defects causes epoxy
Resin is difficult to all infiltrate on FeCuNbSiB surface, it is impossible to reach to encapsulate the purpose of FeCuNbSiB nanometer band.So it is existing
Before epoxy encapsulation, FeCuNbSiB strip surface is carried out load thin film, due between chemical film to FeCuNbSiB
Substrate surface caking property is poor, and the longer basement membrane that is easily caused was peeled off and came off the time, reduced the performance of epoxy encapsulation, so system
Standby a kind of resistance to stripping, peel FeCuNbSiB area load membrane material is necessary.
Summary of the invention
The technical problem to be solved: after existing FeCuNbSiB band overlay film, owing to strip surface exists
Substantial amounts of periodicity stomatal band and cold shut lines, the overlay film permanent seal cooling making strip surface is poor, time length be easily peeled come off lack
Fall into, it is provided that the preparation method of a kind of surface complexation overlay film FeCuNbSiB band, the present invention is by carrying Exocarpium Juglandis Immaturus
Take, after collecting tannic acid concentrated solution, then to its esterification modification, can be formed surely with metal by tannic acid two phase ortho-phenolic hydroxyls
Fixed chelate, after sheet metal strip open-assembly time in atmosphere is longer, by moisture in air and oxide etch effect, makes tannin
Acid esters compound is tightly adsorbed in strip surface, and durability is greatly improved, and has wide prospect of the application.
