Embodiment 1
[0019] The base epoxy resin E-51 of 40 parts by weight, the modified epoxy resin TDE-85 of 60 parts and the antifoaming agent of 0.3 parts are mixed and stirred evenly, and defoaming is used as the resin component; 10 parts of m-benzene Dimethylamine condensate and 15 parts of benzyl glycidyl ether were reacted at 60°C for 60 minutes, then 50 parts of T403 were added, mixed and stirred evenly, defoamed, cooled to room temperature, and used as a curing agent component. When in use, mix and stir the resin component and curing agent component according to the ratio of 100:75, then let it stand for defoaming for 5 minutes to obtain epoxy glue. Mixed viscosity 1780mpa.s; pot life ≥ 3h; 100g curing exothermic peak 56°C; ABS-ABS substrate lap shear strength 6.17Mpa; DSC method test Tg 97.1°C.
Embodiment 2
[0021] Mix and stir the basic epoxy resin E-51, 45 parts of modified epoxy resin AG-80 and 0.5 part of defoamer in a weight ratio of 55 parts, and defoam, as a resin component; 10 parts of m-benzene Diamine and 25 parts of benzyl glycidyl ether reacted at 80°C for 30 minutes, then added 20 parts of D230 and 30 parts of D400, mixed and stirred evenly, defoamed, and cooled to room temperature, as a curing agent component. When in use, mix and stir the resin component and the curing agent component according to the ratio of 100:85, and then let it stand for defoaming for 5 minutes to obtain the epoxy glue. Mixed viscosity 1830mpa.s; pot life ≥ 3h; 100g curing exothermic peak 49°C; ABS-ABS substrate lap shear strength 5.89Mpa; DSC method test Tg 91.8°C.
Embodiment 3
[0023] Mix and stir the base epoxy resin E-51, 30 parts of modified epoxy resin AG-80 and 0.4 part of defoamer in a weight ratio of 70 parts, and defoam, as a resin component; 10 parts of m-benzene Dimethylamine and 18 parts of phenyl glycidyl ether were reacted at 70°C for 45 minutes, then added 32 parts of T403 and 10 parts of D230, mixed and stirred evenly, defoamed, and cooled to room temperature, as a curing agent component. When in use, mix and stir the resin component and the curing agent component according to the ratio of 100:70, and then let it stand for degassing for 5 minutes to obtain the epoxy glue. Mixed viscosity 1940mpa.s; pot life ≥ 3h; 100g curing exothermic peak 53°C; ABS-ABS substrate lap shear strength 6.05Mpa; DSC method test Tg 95.2°C.
