Example Embodiment
[0019] Example 1
[0020] 100 parts by mass of vinyl-terminated polydimethylsiloxane with a viscosity of 1000 mPa·s, 20 parts by mass of vinyl MQ silicone resin (vinyl content of 0.5%, M / Q value 0.8), 4.5 parts by mass of viscosity 50mPa·s polymethylhydrogensiloxane, 1.5 parts by mass of vinyltrimethoxysilane, 0.02 parts by mass of 1-ethynyl-1-cyclohexanol and 0.3 parts by mass of platinum content of 4000ppm Castel catalyst were added to the high-speed disperser, Stir for 1 hour to obtain a low-viscosity, high-transparent, self-adhesive silicone potting glue. The performance test showed that the viscosity was 1500 mPa·s, the light transmittance was 97%, and the bonding tensile shear strength (abbreviated as shear strength, the same below) was 1.02 MPa. The detailed results are shown in Table 1.
Example Embodiment
[0021] Example 2
[0022] 100 parts by mass of vinyl-terminated polydimethylsiloxane with a viscosity of 800 mPa·s, 30 parts by mass of vinyl MQ silicone resin (vinyl content of 1%, M / Q value of 1), 5 parts by mass of viscosity 30mPa·s polymethylhydrogensiloxane, 2 parts by mass of vinyltrimethoxysilane, 0.01 parts by mass of 1-ethynyl-1-cyclohexanol and 0.4 parts by mass of platinum content of 2500ppm Castel catalyst were added to the high-speed disperser, Stir for 2h to obtain a low-viscosity, high-transparent, self-adhesive silicone potting glue. The performance test showed that the viscosity was 1800 mPa·s, the light transmittance was 97%, and the shear strength was 1.15 MPa. The detailed results are shown in Table 1.
Example Embodiment
[0023] Example 3
[0024] 100 parts by mass of vinyl-terminated polydimethylsiloxane with a viscosity of 2000 mPa·s, 15 parts by mass of vinyl MQ silicone resin (vinyl content of 6.5%, M / Q value of 1.2), and 7.5 parts by mass of viscosity 150mPa·s polymethylhydrogensiloxane, 1.5 parts by mass of 3-methacryloxypropyltrimethoxysilane, 0.02 parts by mass of 1-ethynyl-1-cyclohexanol and 0.2 parts by mass of platinum with a content of 5000 ppm calories Stir catalyst was added to the high-speed disperser and stirred for 3 hours to obtain a low-viscosity, high-transparent, self-adhesive silicone potting sealant. The performance test showed that the viscosity was 2300 mPa·s, the light transmittance was 98%, and the shear strength was 1.03 MPa. The detailed results are shown in Table 1.
