- Silica filling amount (parts by mass) 220 300 220 300
- a tensile shear adhesive strength test piece was prepared using the curable resin composition C of Sample No. 1 in the same manner as in Example 1. Then, using a thermal shock tester (Model: TSEL-2200_2, manufactured by ITEC Co., Ltd.), a heat cycle test was conducted in which the prepared test piece was repeatedly immersed in a liquid layer at -30 ° C and 150 ° C every 7 minutes. Was. After repeating 100 times, 500 times, 1000 times, 2000 times, and 3000 times, the tensile shear adhesive strength was measured in the same manner as in Example 1. Table 8 shows the results.
- a spherical alumina-containing (meth) acrylic resin-based liquid I consisting of 2.5 parts by mass of retrimethoxysilane and 1400 parts by mass of spherical alumina shown in Table 1 was obtained.
- Cobalt otathenate was added to the spherical alumina-containing acrylic resin-based liquid material J as a decomposition accelerator for organic peroxides. 1.25 parts by mass was added to 100 parts by mass of the acid ester monomer to obtain a curable resin composition K (Sampnore No. 23). The resulting curable resin composition K had a tensile modulus of 3020 MPa. A heat cycle test was performed on the curable resin composition K (Sample No. 23) in the same manner as in Example 4. Table 8 shows the results as in Example 4.
- the curable resin composition of the present invention has fluidity and excellent workability, while the cured product is flexible and has a low modulus of elasticity and is capable of radiating heat generated by electronic components. It has the characteristics of high thermal conductivity and good heat cycle resistance. For this reason, it can be applied to an adhesive used for bonding such as a potting material to seal an electronic component, a heat splitter in a semiconductor package, a heat sink, and a heat sink. In addition, it has excellent environmental resistance and can be preferably applied to the industrial field.
