THERMALLY CONDUCTIVE PRESSURE-SENSITIVE ADHESIVE, ADHESIVE SHEET CONTAINING THE SAME, AND METHOD FOR FIXING ELECTRONIC PART TO HEAT-RADIATING MEMBER WITH THE SAME |
摘要 |
A thermally conductive pressure-sensitive adhesive which is excellent in thermal conductivity and adhesive properties, has a high adhesive strength especially at high temperatures (high holding power under high-temperature shear), undergoes no abrupt viscosity increase during or after adhesive production, and has excellent stability. The adhesive comprises: (a) 100 parts by weight of a copolymer of a monomer mixture comprising 70 to 99 wt.% monomers consisting mainly of alkyl (meth)acrylates in which the alkyls each has 2 to 14 carbon atoms on the average and 30 to 1 wt.% copolymerizable monomer having an acidic or basic polar group in the molecule; and (b) 10 to 300 parts by weight of a thermally conductive filler having the same polar groups as the copolymerizable monomer and a purity of 95 wt.% or higher. The adhesive sheet comprises a substrate and, formed thereon, a layer of the thermally conductive pressure-sensitive adhesive. The method for fixing an electronic part to a heat-radiating member comprises the use of the adhesive or the adhesive sheet.
