Embodiment 1
[0025] The first step is to weigh 10% of resin, 1.0% of curing agent, 0.2% of accelerator, 1.5% of diluent, 0.2% of coupling agent, 0.28% of thixotropic agent, 0.3% of anti-sedimentation agent and conductive additive in order according to the mass parts 0.2%, stir and disperse with a high-speed disperser for 20-60 minutes to obtain a resin mixture.
[0026] The second step is to weigh a certain proportion of 86.32% silver powder, mix it with the above resin mixture, and stir and disperse it with a high-speed disperser for 20-60 minutes to obtain a uniform slurry.
[0027] In the third step, the prepared slurry is ground on a three-roll mill until the particle size distribution is less than 8 μm, and then passed through a 500-mesh polyester net to obtain a uniformly ground slurry.
[0028] The fourth step is to put the above slurry into the planetary degassing machine and rotate at 200rpm, rotate at 2000rpm for 15 minutes, and then the finished product can be obtained.
