It is necessary to have excellent antistatic effect and electromagnetic shielding properties. JP-A-56-89447, JP-A-57-65754, and JP-A-54-90596 disclose a method of forming a conductive circuit using short metal fibers in a plastic resin, thereby imparting conductivity to the resin itself. It is disclosed that it can be made to last. Such short metal fibers are difficult to form intertwining points between each fiber in the resin. Therefore, large amounts of metal fibers are required to effectively exhibit electrical conductivity. This metal fiber also tends to break when kneaded into the resin, and during beret manufacturing, it is bent to 1/2 to 1/3 of its original length, and during molding, it is further broken, resulting in a product that is much shorter than its original length. I'm getting used to it. Therefore, it is difficult on an industrial scale to obtain a product with excellent conductivity even if a large amount of metal fiber is kneaded into the base resin as in the above publications. Even if long metal fibers are used for the purpose of increasing conductivity, long fibers with a length of 1 cm or more are difficult to knead into the resin. Moreover, it requires a high degree of skill and skill to knead the material without breaking it. Even if long fibers are kneaded into a resin to produce pellets, the long fibers will break during the molding process, making it impossible to obtain a product with excellent conductivity. It is also possible to use ultra-fine metal fibers to make them less likely to break, but since such ultra-fine fibers have extremely low apparent specific gravity, it is necessary to use large bulk metal fibers to achieve the desired conductivity. must be used. It is technically difficult to uniformly knead such bulky fibers into a resin. It is also difficult to mold it into a desired shape by means such as injection molding. Moreover, since it is difficult to mix the metal fibers uniformly, there is a risk that the product will have non-uniform conductivity.
Another method is to fill the base resin with metal powder, but for the same reason, a large amount of powder must be used to obtain good conductivity.

融温度が30℃以上高い組合わせが好ましい。 Examples of the material of the metal powder or metal fiber contained in the plastic film strip include nickel, iron, stainless steel, and copper. The resin constituting the film strips must have a higher melting temperature than the base resin so that it does not mix uniformly with the base resin under the molding temperature conditions when it is heated and kneaded with the base resin. required, the difference is 30℃
It is preferable that there be more than one. Furthermore, it is preferable that it is incompatible with the base resin. Examples of film resins include nylon 6, nylon 66,
Polyester, polyphenylene sulfide, polycarbonate, polyamide, etc. are used. As the base resin, for example, polypropylene, polypropylene copolymers such as polypropylene-polyethylene copolymers, ABS, PVC, etc. are used.
These base resins and film resins may be used in any combination as long as the film resin has a high melting temperature, but as mentioned above, a combination in which the film resin has a melting temperature 30° C. or more is preferred.

かもその導電率にはバラツキがない。 The metal powder or metal fiber is heated and kneaded with the film resin. The blending ratio of metal powder or metal fiber is preferably in the range of 100 to 900 parts by weight based on 100 parts by weight of the film resin. After both are kneaded, they are formed into extruded pellets. Next, this is formed into a film with a thickness of 0.5 to 1.0 mm, and further cut and cut into pieces by known means.
Cut into strips of film about 10 to 20 mm long. This is mixed with 100 parts by weight of the above base resin at a ratio of 80 to 400 parts by weight. Since the film strips are a composite of metal powder or metal fibers and resin, they are kneaded into the base resin and then molded into the desired shape using a molding device such as an extruder, injection molding machine, or calendar roll. Even if an external force is applied to the material, it will only undergo deformation such as stretching or bending.
It won't break or tear. Therefore, the conductive circuit can stably exist in the base resin, and as a result, the resulting composition has extremely high conductivity. Moreover, there is no variation in its conductivity.
