Embodiment 1

[0075] First, 8.0 parts by weight of the resin A, 91.9 parts by weight of the ferromagnetic material, and 0.1 parts by weight of Pc were blended. About 5 mL of butyl carbitol (manufactured by Wako Pure Chemical Industries, Ltd.) and about 3 mL of methyl ethyl ketone (MEK) (manufactured by Wako Pure Chemical Industries, Ltd.) were added thereto and mixed using a planetary mixer to prepare magnetic enhancement resin.

[0076] The thickness t of the optical microscope slide 3 (manufactured by As One Corp.) was measured with a micrometer (manufactured by Mitutoyo Co., Ltd., measuring range: 1 μm to 25 mm) 0 . The magnetic enhancement resin was applied to the optical microscope slide 3 in such a manner that the coating thickness was about 100 μm. It was calcined at about 160° C. for about 30 minutes using an electric oven to form the magnetic enhancement resin layer 4 . The slide glass 3 for an optical microscope and the magnetically enhanced resin layer 4 are collectively refer...

Embodiment 2 and 3 and comparative example 1

[0081] The operation was carried out in the same manner as in Example 1 except that the blending ratio of the materials used was as shown in Table 1. The blending ratio and the results are shown in Table 1. The amounts of each blended material in Table 1 are expressed in parts by weight relative to 100 parts by weight of solid content.

Embodiment 4～6 and comparative example 2

[0085] In order to prepare a test body, the operation was carried out in the same manner as in Example 1 except that the blending ratio of the materials used was as shown in Table 2. The blending ratios and results are shown in Table 2.

Abstract

The main purpose of the present invention is to provide a magnetically enhanced resin or the like having increased magnetic permeability. The magnetically enhanced resin is characterized by containing a ferromagnetic substance, a compound having a macrocyclic p electronic structure, and an adhesive resin. The ferromagnetic substance is preferably a powder of a Fe-Ni alloy, a Fe-Ni-Mo alloy, a Fe-Ni-Cu alloy, or a Fe-Al-Si alloy. The ferromagnetic substance is also preferably a powder of Permalloy, Supermalloy, Sendust, or a ferrite. The compound having a macrocyclic p electronic structure is preferably phthalocyanine, porphyrin, polycyanine, or substitution products thereof, or ligands thereof with a metal. The adhesive resin is preferably an epoxy resin, a melamine resin, a polyimide resin, a polycarbonate resin, a phenolic resin, or a fluorosilicone resin. The average particle size of the ferromagnetic powder is preferably 0.1-100 µm.

Description

technical field [0001] The present invention relates to the technical field of magnetically enhanced resins, coatings using the magnetically enhanced resins, and the like. Background technique [0002] Resin-bonded magnetic materials are characterized by low molding temperature, easy machining, precision molding, and low high-frequency magnetic loss. In particular, because of its low high-frequency magnetic loss, the magnetic material is expected to be applicable to small magnetic parts of special shapes and the like. However, conventional resin-bonded magnetic materials have low magnetic permeability, which limits their use as magnetic materials. [0003] Meanwhile, it is known that adding a thermosetting resin and a metal chelate compound to Mn-Zn ferrite powder can improve the magnetic properties of the resulting composition (see Non-Patent Document 1). However, the document only describes that equal amounts of Co chelate powder, Fe chelate powder, Mn chelate powder and...
