〔産業上の利用分野〕
本発明は高い導電性を保有し、かつ柔軟性に優れ、機械
強度の高い導電性樹脂組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conductive resin composition that has high electrical conductivity, excellent flexibility, and high mechanical strength.

強度が急激に低下し、導電性は満足できる範囲にあるが
物性面で製品にならぬ事が多い。Conventionally, in order to impart high conductivity to a resin, it is common to fill the resin with a high amount of conductive filler. However, when a polyolefin resin is highly loaded with these conductive fillers, the mechanical strength rapidly decreases, and although the conductivity is within a satisfactory range, the product is often unsuitable in terms of physical properties.

物の使用量は急速に伸び一〇いる。Recently, with the development of the electronics industry, the usage of these conductive resin compositions, including electromagnetic shielding materials and antistatic materials, has been rapidly increasing.
しかし、機械強度が低いため、フィルムやシートの分野

。The present invention was developed as a result of research aimed at obtaining a conductive resin composition that would yield conductive molded products with high physical properties that could not be obtained with conventional conductive resin compositions. By adding a conductive filler to the resin composition, the mechanical strength is greatly improved compared to the conventional conductive resin composition made of Golyolefin resin alone, and the dispersion of the conductive filler is also improved. As a result, they found that the conductivity was improved, and based on this knowledge, they conducted various studies and completed the present invention.

性樹脂組成物である。The present invention is a highly conductive resin composition prepared by adding 10 to 100 parts by weight of a conductive filler to 100 parts by weight of a resin composition in which 100 parts by weight of a hylioolefin resin is mixed with 20 to 200 parts by weight of an elastomer.

まれる。The polyolefin resin used in this JJ includes homopolymers of olefins such as ethylene, propylene, and butene, or copolymers with different types of olefins, as well as copolymers of vinyl acetate, acrylic esters, etc. .

の低下がみられる。If the amount of elastomer is less than 10 parts by weight per 100 parts by weight of I7 olefin resin, it will not contribute to improving the mechanical strength, and if the elastomer is used upwind during 100 parts by weight, the molded product will become too flexible. In the case of coalescence, a decrease in chemical resistance is observed.

Furthermore, metal powder, metal fiber, and inorganic filler include metal and gold IA.
Those coated with oxide are used. Carbon black is preferable because it is inexpensive, has good chemical resistance, and has little change over time, but metal powder and metal fibers are preferable for electromagnetic shielding purposes.
