中に均一に分散させることが難しかった。"Prior Art and its Problems" In recent years, conductive paints and conductive plastics have come into use for the purpose of preventing static electricity and shielding electromagnetic waves. These conductive paints, conductive plastics, and the like contain conductive fillers such as carbon powder and metal powder. However, since these conductive fillers are in powder form, sufficient antistatic effect and electromagnetic wave shielding effect cannot be obtained considering the amount of the conductive filler. Furthermore, when mixed with a resin, the filler tends to settle, making it difficult to uniformly disperse the filler in the resin.

使用できなかった。On the other hand, it is known that glass fibers coated with metal are contained in plastic to provide electromagnetic wave shielding properties and radio wave reflective properties. - However, since the conductive material is made of glass fiber coated with metal, the product form is fibrous, mat, nonwoven, etc., and it is necessary to incorporate it into the plastic as a conductive layer. , it was inconvenient to handle. Furthermore, it could not be used for conductive paints.

難になり、フィラーの粗さが目立つ。The milled fiber herein refers to glass fiber monofilament cut into appropriate lengths and further pulverized using a ball mill, fret mill, hammer mill, or the like. In this case, the length of the milled fiber is 20-500
The weight and thickness are preferably 3 to 23 #L. If the length and thickness are smaller than the above, the antistatic and electromagnetic wave shielding effects will not be sufficient, and the length and thickness will be smaller than the above. If the filler is large, it will be difficult to disperse it uniformly when mixed into the resin, and the roughness of the filler will become noticeable.

できる。The conductive filler of the present invention can be mixed into a plastic such as a thermoplastic resin and used as, for example, an electromagnetic wave shielding material for housings of electrical equipment, and a radio wave reflecting material for parabolic antennas. It can also be mixed into a paint to form a conductive paint and used for purposes such as preventing static electricity.

混合することができ、利用範囲も広い。Since the conductive filler of the present invention uses milled glass fibers, it has an elongated shape as a whole and has a lighter specific gravity than metal powder. Therefore, when mixed into a resin, it is uniformly dispersed without settling. Furthermore, since the surface of the milled fiber is thinly coated with metal, better electromagnetic shielding properties, radio wave reflection properties, and antistatic properties can be obtained compared to metal powder, carbon powder, etc. Furthermore, since it is in the form of a fine powder, it can be easily mixed into resin and has a wide range of applications.
