Thermally Conductive Adhesive Composition and Adhesion Method
First Claim
1. A thermally conductive adhesive composition comprising:
- (A) a polymerizable (meth)acrylic compound comprising at least one of a (meth)acrylic monomer and a (meth)acrylic oligomer;
(B) an organic peroxide;
(C) a thermally conductive filler; and
(D) a vanadium compound,wherein the volume ratio α
of the polymerizable (meth)acrylic compound (A) to the thermally conductive filler (C) determined by the following formula (1) is 0.40 to 0.65;
Volume ratio α
=Volume of Thermally conductive filler (C)/(Volume of Polymerizable(meth)acrylic compound (A)+Volume of Thermally conductive filler (C))
(1)wherein 40 to 100% by mass of the thermally conductive filler (C) is subjected to hydrophobic surface treatment.

Abstract
A thermally conductive adhesive composition contains a polymerizable (meth)acrylic compound (A) comprising at least one of a (meth)acrylic monomer and a (meth)acrylic oligomer, an organic peroxide (B), a thermally conductive filler (C) and a vanadium compound (D). The volume ratio α of the polymerizable (meth)acrylic compound (A) to the thermally conductive filler (C) determined by the following formula (1) is 0.40 to 0.65. 40 to 100% by mass of the thermally conductive filler (C) is subjected to hydrophobic surface treatment.
Volume ratio α=Volume of Thermally conductive filler (C)/(Volume of Polymerizable(meth)acrylic compound (A)+Volume of Thermally conductive filler (C)) (1)
