る。[Technical background of the invention and its problems] In recent years, electronic equipment has been developed to protect electronic circuits from external interference radio waves and to prevent unnecessary radio waves generated from transmitting circuits from leaking to the outside. It is required that the housing be made of an electromagnetic shielding material. Examples of such electromagnetic shielding materials include metals and conductive synthetic resins. Although the former metals have excellent electromagnetic shielding effects, they have drawbacks such as being heavy, expensive, and have poor processing +4, so the latter The use of conductive synthetic resins is becoming mainstream.

、成形品の機械的強度が低下するという欠点があった。Methods of imparting conductivity to synthetic resin include forming a conductive layer on the surface by applying conductive paint, spraying or plating metal after molding the synthetic resin, and forming a conductive layer inside the synthetic resin. There is also an internal addition method in which conductive fillers such as carbon or metal powders or fibers are added. The method of forming a conductive layer on the surface of a synthetic resin increases the number of steps and is not suitable for mass production, and also has the disadvantage that the conductive layer peels off after long-term use, so expectations have been placed on the internal addition method. There is. However, the internal addition method also had the following problems. In other words, in order to provide the desired electromagnetic shielding effect, it is necessary to incorporate a large amount of conductive filler such as carbon or metal, which may cause dispersion problems or reduce the mechanical strength of the molded product. The disadvantage was that it decreased.

電性成形材料が１９られていないのが現状である。Furthermore, when a synthetic resin is filled with metal or the like, there is a problem in that the synthetic resin deteriorates. Furthermore, metal fibers and highly flexible fillers tend to clump together in a single state (they have the disadvantage of requiring pretreatment such as loosening for mixing).Furthermore, due to differences in specific gravity and shape, Uniform kneading requires advanced techniques and skills.Also, when handling work clothes for filling +4, IIM may get stuck or touch the skin, causing physical pain such as pain and itching. Hygiene problems are also likely to occur.Therefore, the manufacturing of the molding material should be as simple as possible, and it should be possible to operate in a closed system, and the form of the filler should be constant (do not change).
was desired. In other words, the filling amount of the conductive filler is small, the N magnetic wave shielding effect is large, it can be mixed uniformly with the synthetic resin, it is good for environmental hygiene, and it does not reduce or deteriorate the strength of the synthetic resin! At present, there is no conductive molding material available that will not cause any damage.

The amount is preferably 1 to 10% by weight based on the molding material. If the filling amount is less than 1% by weight, there is no effect on the conductivity, and if it exceeds 10% by weight, the specific gravity becomes too large and the cost becomes undesirable.
