が激しく、長時間の使用は難しい状況でありた。The present inventors have discovered that when molding thin films and fibrous extrusion products using highly conductive resin compositions, mainly carbon-based high conductivity resin compositions, molding troubles and product performance deterioration due to the presence of aggregates have always been reported. Based on our experience, we found that these solutions cannot be solved only by the molding conditions and the cross-wire conditions of the highly conductive resin composition. However, the discharge amount changed drastically over time, making it difficult to use it for a long time.

徴とする樹脂組成物の製造方法である。The present invention is characterized in that, during the production of a conductive resin composition, filler aggregates contained in the conductive resin composition are removed using a filter having a deep filtration structure with a porosity of 5D% or more. This is a method for producing a resin composition.

い。In the present invention, the conductive resin composition refers to a resin composition obtained by filling a resin with a large amount of conductive filler, and a resin composition having a volume resistivity of 10'Ω. say. Conductive fillers include metal particles such as copper, nickel, and silver, non-metal conductive particles such as carbon black and graphite powder, or insulating particles and non-metal conductive particles whose surfaces are plated or coated with metal. There are conductive fibers such as carbon fiber and metal fiber. Considering cleaning of the filter, etc., carbon filler is preferable for use.

The metal fiber is preferably made of corrosion-resistant stainless steel. Furthermore, the porosity has a large effect on the change in discharge rate over time in the case of F, but if the porosity is less than 50%, the porosity will be close to that of general wire mesh, making it difficult to maintain the discharge rate for a long time. In order to carry out a long-time evaporation, a porosity of 50 or more is required, and a porosity of 70 or more is preferable. The filtration filter may be attached to the tip of a mixing device for manufacturing the conductive resin composition, or it may be attached to the tip of an extruder for molding and filtered immediately before molding.

Furthermore, it has been revealed that it is possible to produce thin films with a thickness of 20 μm or more with pinholes on the surface, so it can be said to be the optimal material for the trend toward lighter, thinner, shorter, and smaller batteries.
