The present invention provides a non-polysiloxane-based material, excellent flexibility, and excellent durability such as heat aging resistance, moisture and heat resistance and heat shock resistance, and a heat dissipation structure using it, and also provides the heat conduction It has excellent operability in the kneading step during the production of the flexible sheet, and is suitable for use as a resin composition for the adhesive material of the thermally conductive flexible sheet.nn n n The present invention relates to: a resin composition containing a block urethane prepolymer, a predetermined epoxy compound and a curing catalyst; and a heat conduction formed by curing a mixed composition containing the resin composition and a thermally conductive inorganic filler Flexible sheet; and a heat dissipation structure using the thermally conductive soft sheet. Wherein, the blocked urethane prepolymer is a reaction product of an aliphatic diisocyanate compound and a hydrogenated polybutadiene polyol having hydroxyl groups at both ends, and the aforementioned reaction product is an isocyanate at the end The group is formed by a block of an aromatic hydroxy compound. |
