Example Embodiment
[0057] Example 1
[0058] In this case, the solvent-free conductive glue is composed of components of the following mass:
[0059]
[0060]
[0061] This example has the preparation method of such a solvent-free conductive glue as follows:
[0062] 1) According to the distribution, the solvent-free polyester resin and the dispersant BYK168 are mixed, and uniform is dispersed;
[0063] 2) Add a single-walled carbon nanotube slurry Matrix 201, high speed at a speed of 3000r / min, a high speed of 1 hour, to fineness ≤ 5 μm;
[0064] 3) Add the antifoaming agent TEGO900, disperse uniform;
[0065] 4) Add nano silver powder, uniform dispersion;
[0066] 5) Add HDI enclosed curing agent, uniform dispersion, resulting in finished products.
