[Industrial Application Field] The present invention relates to an electrically conductive resin composition. Specifically, the present invention relates to a resin composition in which a specific conductive composition is dispersed in a resin. [Prior Art] Conductive resin compositions have been developed for the purpose of preventing static electricity, imparting easy plating properties, imparting electromagnetic shielding properties, and the like. For example, it is a conductive resin composition to which metal powder or fibers such as aluminum or stainless steel, carbon black, carbon fibers, etc. are added. [Problems to be Solved by the Invention] Although the purpose of imparting conductivity to the composition described above has been achieved to some extent, the method of adding metal powder or fibers requires expensive additives and is not compatible with resin. There are problems such as difficulty in mixing and molding the resulting composition. On the other hand, in the method of adding carbon black, although the additive is relatively inexpensive, it is difficult to mix it with the resin, and it is difficult to uniformly disperse it. In addition, in order to improve the physical properties of the resin, talc,
Blending fine particles of inorganic compounds such as calcium carbonate and mica has been carried out, but this method can improve the physical properties of the resin and has the advantage of being able to mix tens of weight percent into the resin. , conductivity cannot be imparted. [Means for Solving the Problems] The present inventors have conducted extensive studies on conductive resin compositions that have solved the above problems, and have completed the present invention. That is, the present invention provides a five-membered heterocyclic compound polymer composition obtained by co-pulverizing a five-membered heterocyclic compound, an inorganic compound, and an oxidizing agent, with or without removing the excess oxidizing agent. It is a conductive resin composition that is dispersed in a resin. The five-membered heterocyclic compound polymer composition which is important in the present invention can be produced as follows. Examples of inorganic compound particles include metal oxides, hydroxides, carbonates, etc. Among them, oxides,
Carbonates are preferred because they are commercially available in various particle sizes for improving the physical properties of resins. Specifically, magnesium oxide, alumina, silica, zinc oxide,
Examples include iron oxide, titanium oxide, barium oxide, talc, and mica. These inorganic compound particles may be heat-treated to remove crystal water and adhering water prior to use. The particle diameter of these inorganic compound particles is usually 0.01 μm to 100 μm. Inorganic acids, metal compounds, etc. are effective as oxidizing agents. Examples of inorganic acids include sulfuric acid, hydrochloric acid,
Examples include nitric acid and chlorosulfonic acid. As the metal compound, compounds known as Lewis acids are preferably used, such as aluminum, tin,
titanium, zirconium, chromium, manganese, iron,
Examples include chlorides, sulfates, nitrates, and acetylacetonate compounds of metals such as copper, molybdenum, tungsten, ruthenium, palladium, and platinum. Furthermore, organic compounds such as benzoquinone and diazonium salts can also be used. In particular, chlorides and sulfates of iron and titanium are preferred. These oxidants are 2
It is also possible to use a mixture of more than one species. The weight ratio of the oxidizing agent to the inorganic compound is generally 0.0001 to 1 by weight relative to the inorganic compound. The five-membered heterocyclic compounds used include pyrrole, furan, thiophene, selenophene, tellurophene and derivatives thereof. Among these, pyrrole derivatives such as pyrrole, N-alkylpyrrole, N-arylpyrrole, and substituted pyrrole substituted with an alkyl group or a halogen atom at the 3rd and/or 4th position are preferred from the viewpoint of reactivity. The weight ratio of the five-membered heterocyclic compound to the inorganic compound is 0.001 to 1 weight ratio, usually 0.05 to the inorganic compound.
-1 weight ratio is preferred. The five-membered heterocyclic compound polymer composition used in the present invention can be produced simply by co-pulverizing the five-membered heterocyclic compound, the inorganic compound, and the oxidizing agent. There are no particular restrictions on the method of co-grinding.
Any method using a variety of conventional pulverizers, such as a ball mill, roll mill, centrifugal roll mill, rotary pulverizer, vibratory mill, etc., may be used. There are no particular restrictions on the grinding temperature, but -100℃
It is generally carried out at ~100°C, usually at room temperature ~100°C. Regarding the grinding time, the preferable range varies depending on conditions such as the specifications of the grinder and the amount of filling into the grinder and cannot be specified, but a few minutes to several tens of hours is usually sufficient. There is no restriction on the order of crushing the above three materials, but there are methods such as adding the three materials at the same time and co-pulverizing them, adding the three materials in order and co-pulverizing them, or co-pulverizing the two materials first and then adding the remaining materials. There are ways to do this. Among these, a method of co-pulverizing the oxidizing agent and the inorganic compound and then adding and co-pulverizing the five-membered heterocyclic compound can be preferably employed. The composition of the present invention can be obtained by adding and mixing the five-membered heterocyclic compound polymer composition obtained above with various resins. There are no particular restrictions on the resin used in the present invention,
polyethylene, polypropylene, polystyrene,
Any resin can be used, including thermoplastic resins such as polyvinyl chloride, polymethyl methacrylate, polycarbonate, polyphenylene oxide, polyamide, and polyester. Even thermosetting resins such as polyimide and phenolic resin can be made into conductive resin compositions by mixing a five-membered heterocyclic compound polymer composition in the state of a solvent-soluble prepolymer. . There are no particular restrictions on the method of mixing the resin and the five-membered heterocyclic compound polymer composition, and if the resin is thermoplastic, it may be mixed using a Henschel mixer, etc., and then granulated using an extruder, or mixed using a roll, etc. There are methods of mixing using In the case of thermosetting resins, a method can be adopted in which the resins are mixed in a relatively high viscosity solution or molten state, molded, and then cured. [Example] The present invention will be explained below with reference to Examples. Example 1 1 Manufacture of filler Thakur powder (grade MS manufactured by Nippon Talc Co., Ltd.)

The resulting composite contained 57 g of polypyrrole. 2 Manufacture of conductive resin composition 1 kg of the filler obtained in 1) above was mixed with ethylene content of 9
It was granulated with 10 kg of ethylene/propylene copolymer (wt%) using a 25 mmφ extruder (BT-25) manufactured by Plastic Engineering Research Institute. An injection molded sheet with a thickness of 1 mm was prepared using the obtained composition, and various physical properties were measured as described below. Specific resistance: by two-terminal method Melt flow index: ASTM-D1238 conditions 2.16Kg, 230℃ Yield point stress: ASTM-D638 measurement temperature 23℃ Bending rigidity: ASTM-D747 measurement temperature 23℃ Dupont impact strength: according to JIS K6718 Measurement temperature: 23℃ -10℃ Izot impact strength: ASTM-D256 Measurement temperature: 23℃ -10℃ The measurement results are shown in the table. Comparative Example 1 and Reference Example 1 Sheets were prepared in the same manner as in 2) of Example 1, except that only talc was ground under the same conditions as in Example 1, and the physical properties were measured (Comparative Example 1). Furthermore, for reference, the physical properties of a sheet prepared without adding any filler were also measured (Reference Example 1). The measured results are shown in the table. Examples 2 and 3 Example 1 except that calcium silicate manufactured by Asada Seifun Co., Ltd. (Example 2) or calcium carbonate "Sunmite #800" manufactured by Take Chemical Industry Co., Ltd. (Example 3) was used as the inorganic compound. repeated. The measurement results of physical properties are shown in the table. In addition, polypyrrole is 43g and 37g, respectively.
