With this structure, the resin composition obtainable for the electromagnetic wave absorber can have electromagnetic wave absorbance, small transmittance and small reflectance of electromagnetic waves, as well as show a small variation of reflectance depending on the frequency of electromagnetic waves. <Resina termoplástica> The resin composition of this modality contains a thermoplastic resin. The thermoplastic resins preferably used in this modality are exemplified by polyester resin (thermoplastic polyester resin); polyamide resin; polycarbonate resin; polystyrene-based resin; polyolefin resins such as polyethylene resin, polypropylene resin, and cyclic cycloolefin resin; polyacetal resin; polyimide resin; polyetherimide resin; polyurethane resin; polyphenylene ether resin; polyphenylene sulfide resin; polysulfone resin; and polymethacrylate resin.The resin composition most preferably contains at least one polyolefin resin (preferably polypropylene resin), polycarbonate resin, polyphenylene ether resin, polyester resin or polyamide resin; most preferably contains at least one polycarbonate resin, polyphenylene ether resin, polyester resin or polyamide resin; and most preferably contains polybutylene terephthalate resin.

In a special case where the resin composition of this embodiment contains polybutylene terephthalate resin, and in a more special case where the resin component is substantially composed of polybutylene terephthalate resin, the content of the reactive compound in the resin composition of this embodiment is preferably 0.01 parts by mass or more per 100 parts by mass of polybutylene terephthalate resin, more preferably 0.1 parts by mass or more, even more preferably 0.3 parts by mass or more, even more preferably 0.5 parts by mass or more, and additionally more preferably 0.8 parts by mass or more.

The resin composition of this type may contain only one class of, or two or more classes of, the reactive compound. When two or more classes are present, the total content preferably falls within any of the ranges mentioned. <Retardante de Llama > The resin composition of this type may also have flame retardancy. Flame retardancy is normally achieved by using a flame retardant. Flame retardants include halogen-containing flame retardants, phosphorus-containing flame retardants (metal phosphinate, melamine polyphosphate, etc.), nitrogen-containing flame retardants (melamine cyanurate, etc.), and metal hydroxides (magnesium hydroxide, etc.), with phosphorus-containing and halogen-containing flame retardants being preferred. The phosphorus-containing flame retardant is most preferably metal phosphinate. The halogen-containing flame retardant is most preferably a bromide-containing flame retardant. The resin composition of this modality may also contain a flame retardant auxiliary. A first embodiment of a case where the resin composition of this embodiment has flame retardancy is exemplified by a resin composition containing the thermoplastic resin, the carbon nanotube, and the bromide-containing flame retardant, wherein the electromagnetic wave-absorbing material (preferably carbon nanotube) and the bromide atom (Br) contained in the bromide-containing flame retardant meet the mass ratio of electromagnetic wave-absorbing material (preferably carbon nanotube) / Br of 0.01 to 0.40. The first embodiment preferably contains a flame-retardant auxiliary, and more preferably contains an antimony compound. Particularly with the electromagnetic wave-absorbing material (preferably carbon nanotube) mixed in, the first method can improve electromagnetic wave absorbance. Furthermore, with carbon nanotubes (CNTs) mixed in with the bromide-containing flame retardant, the thermoplastic resin can be prevented from dripping during the combustion test, thus improving the UL94 flame retardancy rating. Dripping can presumably be suppressed because the CNT has a fibrous structure and is highly adhesive to the thermoplastic resin. On the other hand, if the bromide-containing flame retardant is insufficient, the CNT is relatively rich, and the CNT / Br ratio falls outside the predetermined range. The resin composition will undesirably sustain combustion for a period of time due to the abundance of CNT relative to the bromide-containing flame retardant.This is presumably because CNT is carbonic and can spontaneously combust if mixed too much. Now, this method... PACO ίη / ZZΖΠZ / E / YΙΛΙ precisely controls the mass ratio of the bromide atom (Br) contained in the bromide-containing flame retardant, to successfully achieve high flame retardation, while achieving high electromagnetic wave absorption. In the first mode of this application, the mass ratio of the electromagnetic wave-absorbing material (preferably carbon nanotube) to the bromide (Br) atom in the bromide-containing flame retardant, denoted as electromagnetic wave-absorbing material (preferably carbon nanotube) / Br, is 0.01 to 0.40. At or below the lower limit, the electromagnetic wave absorbance is enhanced. At or above the lower limit, the combustion time can be shortened. The flame retardancy of the bromide-containing flame retardant is generally believed to be proportional to the amount of bromide atom. This is based on the fact that the bromide atom is less likely to combine with oxygen, thereby suppressing combustion. Furthermore, the bromide atom reacts with antimony at high temperatures, further enhancing the flame retardancy. The electromagnetic wave-absorbing material (preferably carbon nanotube) / Br is preferably 0.05 or larger, more preferably 0.08 or larger, even more preferably 0.10 or larger, and may be 0.16 or larger, 0.20 or larger, or 0.25 or larger. Meanwhile, the electromagnetic wave-absorbing material (preferably carbon nanotube) / Br is preferably 0.38 or smaller, more preferably 0.35 or smaller, and may be 0.30 or smaller, 0.28 or smaller, or 0.16 or smaller. In particular, with the electromagnetic wave absorbing material (preferably carbon nanotube) / Br controlled to 0.05 or larger, the obtainable resin composition can have electromagnetic wave properties, particularly characterized by high absorbance and low transmittance.Meanwhile, with the electromagnetic wave absorbing material (preferably carbon nanotube) / Br controlled to 0.14 or smaller, the combustion time can be shortened. A second mode of this modality, in which the resin composition of this modality has flame retardancy, is exemplified by a resin composition containing the crystalline thermoplastic resin, the electromagnetic wave absorbing material (preferably carbon nanotube), and the flame retardant, and which shows an absorbance at a frequency of 76.5 GHz, when formed to a thickness of 2 mm and determined by Equation (A), of 40.0 to 100%. With the electromagnetic wave-absorbing material (preferably carbon nanotube) mixed in during the second mode of this process, the formed article can have improved electromagnetic wave absorbance. Also, with the carbon nanotube mixed in with the flame retardant, the formed article can have improved flame retardancy (UL94). This is attributable not only to the effect of the flame retardant but also to the fact that the carbon nanotube has a fibrous form, is highly adhesive to the crystalline thermoplastic resin, and can therefore suppress dripping. Furthermore, the use of the crystalline thermoplastic resin as the primary thermoplastic resin presumably improves the chemical resistance of the formed article. This is presumably due to the effective interaction of these components, without affecting the... PACO ίη / ZZΖΠZ / E / YΙΛΙ adversely with each other, the formed article was obtained with high absorbance of electromagnetic waves, as well as high flame retardancy and chemical resistance. The second mode of the modality preferably, and additionally, contains a flame retardant additive. It also preferably contains a reinforcing material. A third mode of this modality, in which the resin composition has flame retardancy, is exemplified by a resin composition containing the thermoplastic resin, reinforcing fiber, electromagnetic wave-absorbing material (preferably carbon nanotube), and flame retardant, and which exhibits an absorbance at a frequency of 76.5 GHz, when formed to a thickness of 2 mm and determined by Equation (A), of 40.0 to 100%. The resin composition preferably also contains a flame retardant, and more preferably a flame retardant containing bromide. With the electromagnetic wave-absorbing material (preferably carbon nanotube) mixed in during the third mode of this process, the resulting article can have improved electromagnetic wave absorbance. Also, with the flame retardant mixed in along with the CNT, the resulting article can have improved flame retardancy (UL94). This is attributed not only to the effect of the flame retardant but also to the CNT's fiber form, which is highly adhesive to the crystalline thermoplastic resin and can therefore suppress dripping. Furthermore, the addition of the reinforcing fiber presumably improved the deflection temperature under load. This is presumably because the reinforcing fiber can suppress the softening of the resin at high temperatures.Furthermore, the blending of the reinforcing fiber presumably reduces the relative content of the thermoplastic resin, thereby reducing the easily carbonizable component and improving flame retardancy. Presumably as a result of the effective interaction of these components, without adversely affecting each other, the resulting article exhibited high electromagnetic wave absorbance, as well as high flame retardancy and heat resistance.

Examples 1-1 to 1-8, Comparative Examples 1-1 to 1-10<Producción de la Composición de Resina (Gránulo)> From the raw materials listed in Table 1 or 2 above, the individual components selected as summarized in the following Tables were placed in a stainless steel drum and mixed under agitation for one hour. The resulting mixture was fed into an interleaved co-rotating twin-screw extruder ("TEX-30a", from Japan Steel Works, Ltd., screw diameter = 32 mm, L / D = 42) through a main feed port. The contents were plasticized at a preset barrel temperature of 260°C in the first kneading zone. The fiberglass, the proportion of which is given in the following Tables, was fed through a side feeder. The barrel temperature after the addition of the fiberglass was set to 250°C. The contents were melt-kneaded at a discharge rate of 40 kg / h and a screw speed of 200 rpm. PACO Ln / Zznz / E / YIAI was then extruded into strands through a four-hole nozzle (4 mm diameter round hole, 1.5 cm long). The extruded strands were placed in a water bath for cooling, and then fed into a granulator for cutting, to obtain a resin composition (granules). <Resistencia a la Tracción Máxima > The resin granule obtained in this way was dried at 120°C for 5 hours, and then injection milled into an ISO multi-purpose test specimen (4 mm thick) using an injection molding machine ("J85AD", from Japan Steel Works, Ltd.), at a cylinder temperature of 250°C, and at a die temperature of 80°C. Using the molded ISO multi-purpose test specimen, the maximum tensile strength (in MPa) and tensile modulus (in MPa) were measured in accordance with ISO527-1 and ISO527-2. <Velocidad de Incremento de la Resistencia a la Tracción Máxima> The rate of increase in ultimate tensile strength was estimated with respect to a case where carbon black was used as the carbonaceous electromagnetic wave absorber. In this study, the rate of increase was estimated between resins with the same composition. That is, the rate of increase in Example 1-1, Example 1-2, Comparative Example 1-4, Comparative Example 1-5, and Comparative Example 1-8 was estimated based on the ultimate tensile strength in Comparative Example 1-1; the rate of increase in Example 1-3, Example 1-4, Comparative Example 1-6, and Comparative Example 1-9 was estimated based on the ultimate tensile strength in Comparative Example 1-2; The rate of increase in Example 1-5, Example 1-6, Comparative Example 1-7, and Comparative Example 1-10 was estimated based on the maximum tensile strength in Comparative Example 1-3. For example, Example 1-1 shows a maximum tensile strength of 147 MPa, while Comparative Example 1-1 shows a maximum tensile strength of 134 MPa, so the rate of increase for Example 1-1 is given as (147 / 134)χ 100 = 110(%). <Propiedades Flexurales > The resin granule obtained in this way was dried at 120°C for 5 hours, and then injection molded into an ISO multi-purpose test specimen (4 mm thick) using an injection molding machine ("J85AD", from Japan Steel Works, Ltd.), at a cylinder temperature of 250°C, and a die temperature of 80°C. Using the molded ISO multipurpose test specimen, flexural strength (in MPa) and flexural modulus (in MPa) were measured in accordance with ISO178. <Deformación Baja > The resin composition granules were dried at 120°C for 5 hours and then injection molded into a 150 mm x 150 mm x 2 mm square plate test specimen using an injection molding machine ("EC160", Shibaura Machine Co., Ltd.) at a cylinder temperature of 260°C and a die temperature of 80°C. The strain (mm) of the formed article was measured. Low strain was evaluated according to the following criteria. Strain is defined by placing the 150 mm x 150 mm x 2 mm square plate on a flattened surface while being molded. PACO ίη / ZZΖΠZ / E / YΙΛΙ maintains three axes in contact with the plane, and finding a straight line distance between the residual apex and the flattened plane.

Using the obtained test sample, the absorbance determined by Equation (A), reflectance determined by Equation (B), and transmittance determined by Equation (C), all at a frequency of 76.5 GHz, were measured as described below. An Anritsu Corporation "MS4647B Vector Work Analyzer" was used for the measurement. The test sample was measured while aligning the transverse direction (TD) of the molded article parallel to the direction of the electric field. Equation (A) Absorbance (%) = 100 - (--^7x100 +--U7 X 1OθΊ (In Equation (A), R represents the return loss measured by the free space method, and T represents the transmission attenuation measured by the free space method.)

In the Tables, the carbon nanotubes (b-1—1) to (b-1-3) were provided not in terms of the amount of master bath, but in terms of carbon nanotube per se. The articles formed from the resin compositions in Examples 2-1 to 2-5 were found to exhibit high absorbance, excellent flame retardancy and heat resistance, as well as high mechanical strength. On the other hand, the articles formed from the resin compositions in Examples 2-1 to 2-5 were found to exhibit low transmittance and reflectance. INDUSTRIAL APPLICABILITY Millimeter-wave radar has suffered from malfunctions due to noise associated not only with the transmitting electromagnetic wave but also with the reflecting electromagnetic wave. Consequently, a material with high electromagnetic wave absorption, low transmittance, and low reflectance has become increasingly in demand. The resin composition of this invention can meet these requirements and can also meet the demands for higher levels of flame retardancy and chemical resistance. The resin composition of this invention is therefore widely expected for applications where flame retardancy, chemical resistance, and electromagnetic wave absorption are required.
