Example Embodiment
[0033] A graphene nano three-proof adhesive, including the following components by mass percentage: modified polyurethane resin: 26%; functional two-dimensional nano flake graphene: 28%; polyurethane curing agent MDI: 23%; defoamer: 2 %; Hydrophobic fumed silica: 1%; Graphene dispersant: 20%. When preparing the graphene nano three-proof glue, first prepare the materials according to the above-mentioned mass percentages; then add the prepared modified polyurethane resin into the double planetary stirred tank, and add graphite in three times when the temperature is raised to 50-55°C Ene dispersant and functional two-dimensional nano flake graphene, fully stirred in a double planetary stirred tank for 2-3 hours, then cooled to 20-25 ℃, and then added hydrophobic meteorological silica, defoamer, Polyurethane curing agent MDI, stir and mix thoroughly for 2 hours to obtain the finished product, and test and pack it. Among them, when the graphene dispersant and the functional two-dim...
