Embodiment 1
[0014] 15 parts of liquid-terminated carboxylated nitrile rubber epoxy resin, 0.05 parts of 3-glycidyl etheroxypropyl trimethoxysilane, 1.5 parts of bis-nitrile amine, 65 parts of micron silver powder, 4 parts of nano-silver particles, and 5 parts of carbon nanotubes .
[0015] The preparation process is as follows: Weigh the raw materials by weight, add micron silver powder, nano silver particles and carbon nanotubes to the liquid carboxylated nitrile rubber epoxy resin and stir at a speed of 400-500r / min for 15 minutes, then add dispersant and curing agent Continue to stir for 15 minutes. After mixing evenly, move to a three-roll machine and roll and mix continuously for three times to prepare the conductive adhesive.
Embodiment 2
[0017] 20 parts of liquid-terminated carboxylated nitrile rubber epoxy resin, 0.2 parts of 3-glycidyl etheroxypropyl trimethoxysilane, 1.5 parts of triethylenetetramine, 70 parts of micron silver powder, 1 part of nano silver particles, 5 parts of carbon nanotubes share.
[0018] The preparation process of the conductive adhesive is as follows: Weigh the raw materials by weight, add micron silver powder, nano silver particles and nano carbon tubes to the liquid end carboxylated nitrile rubber epoxy resin, stir at a speed of 400-500r / min for 15min, then add the dispersant 1. The curing agent continued to stir for 15 minutes. After mixing evenly, it was transferred to a three-roller machine and continuously rolled and mixed three times to prepare the conductive adhesive.
Embodiment 3
