摘要： Provided are a polyurethane-modified epoxy resin composition having satisfactory operability of processing, such as casting or impregnation, in a composition state, a production method therefor, and a composition thereof. The polyurethane-modified epoxy resin is obtained by modifying a secondary hydroxyl group-containing bisphenol-based epoxy resin (a) having an epoxy equivalent from 150 g/eq to 200 g/eq and a hydroxyl equivalent from 2,000 g/eq to 2,600 g/eq with a polyol compound (b) having an Mn of 200 or more, a polyisocyanate compound (c), and a polyol compound (d) having an Mn of less than 200 serving as a chain extender. The polyurethane-modified epoxy resin uses the epoxy resin (a) in an amount from 20 wt % to 60 wt % with respect to the total amount of the respective components (a), (b), (c), and (d), and contains a polyurethane having the epoxy resin (a) added to both terminals thereof and/or one terminal thereof.

摘要： The present invention provides a method for producing an artificial graphite electrode that enables kneading and subsequent mixing to be carried out without having to increase an amount of binder pitch used even in the case of needle coke having a large pore volume. An artificial graphite electrode is produced by kneading binder pitch with needle coke, and performing extrusion molding and then performing baking and graphitization process on the same, wherein a process for kneading the binder pitch with needle coke includes at least two separate kneading stages, and the amount of binder pitch added and kneading time in these kneading stages satisfy a kneading index as represented by formula (1) below within a range of 0.1 to 0.7. Kneading index=(a1/A)×(t1/T) (1)
