In addition, the ferrite molded product made of such a material is processed into a shape such as a plate shape or a rod shape by various methods such as pressing, casting, or pultrusion as shown in Fig. 1(b). It is also possible to provide the adhesive layer 12c underneath. Alternatively, it may be a straight hexahedron as shown in Fig. 1 (4), and in the case of a straight hexahedron, it is preferable that the opening 12b has an opening 12a at least on both surfaces. According to Fig. 1(C), only the electric wiring 15 passes through the inside of the through hole, and an excellent electromagnetic wave shielding effect can be obtained. 2·Cladding material (1) Composition The composition is characterized by a heat-g composition or a strand curable composition containing an «imine resin and an epoxy compound. That is, by using a polyimide resin and an epoxidized human"multiplying wire, it is possible to obtain superior resistance to rhythm or to prevent spattering, and at the same time as electrical σ 叮 逸 逸, such as 'fixed Electrical wiring, and can be caused by electromagnetic wave shielding effect. π, and it is not necessary to cover the entire surface of the ferrite molded article by the use of the cladding material 14 as long as the predetermined impact resistance or the spatter resistance can be paid, that is, the knife can be broken. As shown in Fig. 1 (a) 1263477, when the through hole 12b having the port portion 2a is provided, if it is applied to the inner surface of the through hole Kb, it is difficult to penetrate the electric wiring 15. Therefore, when the entire surface area of the ferrite molded product 1 is 1%, the coating ratio by the covering material is preferably in the range of 〜g(10). However, when the related ferrite molded article 10 is in the form of a flat plate, it is not necessary to consider that the opening portion is buried, so that the coverage ratio by the covering material can be set to 100%. Here, as for the preferred polyimine resin constituting the covering material 14, including polyglycine as a precursor or polyamidoximine resin as a derivative, ester acid II is exemplified. A condensate of an anhydride and a ruthenium compound (diamine compound). More specifically, as the ester dianhydride, 2,2-bis(4-hydroxyphenyl)-propane dibenzoate-3,3,4,4,-tetracarboxylic acid di, anhydride, P-phenylene bis(trimellitic acid monoester anhydride), benzoic acid 3,3,4,4,-ethylethylene glycol, S-tetrawei dianhydride, 4, 4,-biphenyl Double (trimellitic acid monoanhydride),! ,-naphthalene bis (p-benzoic acid mono S phthalic anhydride), 1,2-extension ethyl bis (trimellitic acid monoester anhydride), hydrazine, 3-trimethylene bis (trimellitic acid monophthalic anhydride) ), 1,4-tetramethylene bis(trimellitic acid monoester anhydride), hydrazine, 5-pentamethylene bis(trimellitic acid monoacetic anhydride), 1.6- hexamethylene bis(trimellitic acid monoester) anhydride)#. Further, as the amine compound, 3, 3, bis(aminophenoxyphenyl) stone, 4,4, diaminodiphenyl stone, and u_bis(3_aminophenoxy) can be exemplified. Benzene, phenyldiphenylamine, diaminodiphenylmethyl bis, bis(2-aminoethyl)polydimethyl oxazepine, bis(3,-aminopropyl)polydiphenyl Oxane and the like. In addition, as for the applicable epoxy, oxygen, glycidylamine epoxy. Further, a glycidyl ether epoxy or a glycidyl ester ring may be used as the main raw material of the epoxy, and for example, propylene glycol, tetra 12 1263477 phenylethane, hexahydrophthalic anhydride, bisphenol A, hydrogenation double may be used. Phenol A, bisphenol F, hydrogenated bisphenol F, tetrabromobisphenol A, dimer acid, diaminodiphenylmethane, trimeric isocyanic acid, p-aminophenol and p-hydroxybenzoic acid. Further, in order to use a thermosetting composition containing a polyimine resin or a UV curable composition as a solution, it is preferred to add a sulfoxide solvent such as dimethyl sulfoxide or diethyl sulfoxide, N, N_. Dimethylformate, N,N-diethylformamide, N,N-dimethylacetamide, N,N-diethylacetamide, N-methyl-2-pyrrolidine, phenol' An organic solvent such as cresol, xylene, 4-phenol, catechol, hexamethylphosphonium, butyrolactone or tetrahydrofuran. In addition, in the case of the thermosetting composition or the ultraviolet curable composition constituting the covering material, the amount of the epoxy compound added is set to a value within a range of 5 to 卯 by weight of the polyacrylamide resin. It is appropriate.

The value of the pen hardness increases, and there is a tendency to gradually decrease. Therefore, in order to obtain a good balance of the wrong pen hardness or impact resistance, it is said that the epoxy compound is used with respect to 100 parts by weight of the polythene subsurface fat. The value of the addition amount is preferably set in the range of the weight fraction of the crucible, and is preferably in the range of 5 to 5 Å. In addition, in the thermosetting composition or the ultraviolet curable composition, In addition, the amine compound which is a raw material of the polyimide resin is fine and the amount of the amine compound is equal to (10) by weight, and the amount of the amine compound is preferably in the range of 10 (by weight) (10). 3. The reason is that if the amount of the lake is changed, the amount added is less than the weight of the material. On the other hand, when the amount of the related amine compound added exceeds 3 parts by weight, it is difficult to maintain a uniform film thickness or to reduce the moisture resistance. Therefore, it is preferable to set the value of the amine compound or the anhydride in the range of 2 to 20 parts by weight, based on 100 parts by weight of the polyimine resin, to be set at 3 to 15 parts by weight. The value in the mine enclosure is most suitable. In the thermosetting or ultraviolet curable composition, it is preferred to further contain a lubricant, and the relative weight of 14 1263477 0. 1~30 is divided into (10) and the weight is divided into four parts. · The amount of addition is preferably within the range set. The reason is that it contains _quantitative_slip agent, although it is easy to adjust its water repellency and mechanical properties, but if the amount of _ 敝When it is less than the value of the U weight, there is a case where the effect of the addition is not exhibited. On the other hand, if the amount of the lubricant added exceeds 30 parts by weight, it is difficult to form a uniform film thickness, or It is caused by a decrease in the compatibility between the components. 100 parts by weight of the polyimine resin, the amount of the lubricant added is preferably in the range of 2 to 25 parts by weight, and the value of the range of 3 to 5% is preferably 0. As such a lubricant, for example, a fluorinated acrylic acid resin, a vinylidene fluoride, a fluorinated amine methyl ester, a fluorinated amine resin, a polytrifluoroethylene resin, and a polytetraethylene B can be exemplified. Dilute resin, polyhexa-propylene resin, fluorinated ethylene propylene copolymer resin, polychlorotrifluoroethylene resin, ethylene-hexafluoropropylene copolymer resin, acetonitrile-hexafluoropropylene copolymer resin, polytetraethylene A fluorocarbon resin such as a perfluorocarbon-based ethylene-based copolymer resin. Further, as for the lubricant, in addition to the above-mentioned fluorocarbon resin, it may preferably contain, for example, graphite, molybdenum disulfide, boron nitride, or liquid stone. Wax, oxime oil, fluorine-containing oil, mechanical oil, castor oil, oleic acid, etc. Further, it is preferred to further contain other additives in the thermosetting composition or the ultraviolet curable composition. For example, when forming a film having a uniform thickness, it is preferred to use a dilute solvent of alcohol, ketone, ether, etc., as an additive. In addition, 'for side viscosity or mechanical strength, it is suitable to add glass, quartz, hydroxide, oxidized, kaolin,,, π, 彳, calcium, calcium citrate, magnesium hydroxide and other inorganic fillers, acrylic Organic fillers such as vinegar powder, epoxy powder, polyester resin powder, pigments represented by carbon black, iron oxide, phthalocyanine blue, # H 氧化 钦, etc., metal powder, lubricant, off One of the U surfactant and the coupling agent may be used alone or in combination of two or more. In addition, if it is intended to be colored by the oxy-formed article, it is preferably contained, for example, oxidized chin, titanium red, yellow, oxygen, iron oxide 'ferrite, metal-free ugly pigment, phthalocyanine pigment, A coloring agent such as a pigment, a ruthenium pigment, a nickel phthalocyanine pigment, a tin phthalocyanine pigment, or a copper phthalocyanine pigment is used as an additive. ^...n film formation and viscosity, it is advisable to add, for example, other thermosetting resins or metal oxides. More specifically, as for the μ resin, for example, a single resin or a cis-butadiene quinone imide resin, a urea resin, an ethylene resin, a Wei compound or an unsaturated polyester resin may be used alone or in combination. More than one species. (2) The thickness of the covering material is, for example, a value of /·1 to 15 〇μπ1 in the range of 〇·1 to 15 〇μπ1, and the thickness of the coating material related to the lining system is less than 丨(10) , it is caused by the situation of making the slashing and preventing the splashing. When the thickness of the right-handed material is more than 15 〇 _, it is difficult to form the thickness of the uniform sentence, or the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Therefore, the thickness of the relevant covering material is preferably in the range of 1 to 12 〇 μm, and the value in the range of 10 to ΙΟΟμπι is more preferable. (3) Mechanical strength In addition, as for the mechanical strength of the coated material, the value of the oblique pen measured according to the JIS K K5600 standard is preferably in the range of 1H to 5H. The reason for this is that if the pencil hardness of the relevant covering material is less than 1H, the mechanical strength is lowered, and the impact resistance or the splash-preventing property is also lowered. φ On the other hand, if the pencil hardness of the related covering material exceeds 兕, the adhesion to the ferrite molded article is lowered, and the selection range of the usable material is remarkably reduced. Therefore, it is preferable that the pencil hardness of the relevant covering material is set to be in the range of 2H to 4H. Further, the tensile strength of the coated material at 25 ° C is preferably in the range of 5 Torr to 15 % by weight. The reason for this is that if the tensile strength of the related covering material is less than 5 G%, the mechanical strength is lowered, and the impact resistance or the spatter resistance is also lowered. In addition, if the tensile elongation rate of the coated material exceeds the time of the discussion, there is a case where the selection range of the usable materials is conspicuously reduced. Therefore, the tensile elongation of the relevant covering material is preferably in the range of 70 to 100, and the value in the range of 80 to 100% is more preferable. Further, the tensile strength of the coated material measured in accordance with the JIS Κ K5600 standard is preferably in the range of 100 kgf/mm 2 . 1263477 The reason is that if the tensile strength of the related covering material is less than lkgf/mm2, the mechanical strength is lowered, and the impact resistance or the anti-money dip is also caused. On the other hand, if the tensile strength of the coated material exceeds the dirty gf/W, the selection range of the materials that can be used is remarkably reduced. Therefore, the tensile strength of the relevant covering material is preferably in the range of 5 to 80 kgf/mm2, and the value in the range of 10 to 50 kgf/cm 2 is more preferable. Further, the value of the tensile elastic modulus measured by the JIS K K5600 standard of the coated material is preferably in the range of from 500 kgf/mm2. The reason is that if the tensile modulus of the relevant covering material is less than the value of the postal/deletion 2, the mechanical strength is lowered, and the slashing property or the splashing prevention property is also lowered. . On the other hand, if the tensile modulus of the relevant covering material exceeds 2, the selection range of the usable material is remarkably reduced. Therefore, the value of the tensile elastic modulus of the related covering material is preferably in the range of 12 〇 to 3 〇〇 kgf/mm 2 , and the value in the range of (10) to 25 G kgf/mm 2 is more preferable. . (4) Electrical characteristics In addition, it is preferable to set the electric resistance of the covering material to a value of ΐχΐ〇13 Ω or more. The reason is that the volume resistivity of the related covering material is less than 1 χ 1013 Ω. When the value is added, the electrical property is lowered, and the impact resistance after a long period of time or the splash mitigating property is prevented from being lowered. However, if the volume of electricity in the relevant job is a change in the tree, the condition of the wealth may be excessively restricted. Therefore, the volume resistivity of the relevant covering material is preferably in the range of 1χ1〇ΐ4~1χ1〇18Ω·cm, and the value set in the range of 5x10"~1χ1〇17Ω ·(10) is more suitable. In addition, it is preferable that the insulation breakdown voltage of the covering material is set to be 50 kV/mm or more. The reason is that if the insulation breakdown voltage of the related covering material is less than 50 kV/min, there is an electric special 11 Reduce the 'impact resistance after a long period of time or prevent the decrease of the sagability. However, the relevant hardening conditions or the types of resins that can be used are excessively restricted when the relevant rider is completely worn by Yan Rucheng. Therefore, the insulation breakdown voltage of the related covering material is set to be in the range of 80 to 200 kV/deleted and the value is set to be in the range of 1QG to 18 Qkv/mm.

(10) Internal (4) 12G has a large number of agitating baffles, and the V-clamping plate 105' is rotated by a rotating device (1) disposed under the communicating portion (10), and can be rotated in a specific rotational direction. The ferrite molded article or the thermosetting composition or the ultraviolet curable composition to be a covering material can be loaded into the rotating member 113 by opening the door leaf 1〇3. Therefore, in the state in which the door leaf is closed, the related rotating member 113 is rotated in the horizontal direction with the shaft oil as the center of the towel, and the main paste is centrifuged and the force can apply the coated material 14 to the iron in a uniform thickness. On the surface of the oxygen molded article. 20 1263477 In addition, as shown in FIG. 4(b), there is a drum which is formed to be able to accommodate the inner core 220 of the ferrite molded article and the rotating member M3 having the openable and closable door leaf 2〇3. The applicator 200 thus has a plurality of agitating baffles, a weir and a baffle 2〇5 in the shed space coffee, and the rotating member 213 can also be provided by the rotating device 211 disposed on the side of the communicating portion 209 (4). Composition. Therefore, in the state where the door leaf 2Q3 is opened, the iron emulsion molded article or the thermosetting composition or the ultraviolet curable composition which is the covering material can be loaded into the rotating member 213 by the filling device, and at the same time, the door is closed. In the state, the rotating device 211 is rotated in the vertical direction by the center of the axis a'b', and the covering material 14 can be applied to the surface of the ferrite molded article mainly by centrifugal force and gravity. In the case of using the drum applicator shown in Figs. 4(a) and (8), it is preferable to heat 1 G minutes to 1 at 1 degree of GGC (H, when the thermosetting composition is cured to form In addition, when the outer wire is hardened, for example, the value of the exposure amount is set in the range of the printing-to-deletion 2 to cure the rabbit outer-curable composition. 2.
