Embodiment 1
[0015] In this embodiment, the mass parts of each raw material are as follows: 8 parts of graphene, 16 parts of acrylic resin, 32 parts of water, 6 parts of BYK wetting and dispersing agent, and 5 parts of tricarboxymethylpropane glycidyl ether. The preparation steps are as follows:
[0016] (1) Mix 8 parts of graphene with 12 parts of water to infiltrate the graphene to obtain a graphene premix;
[0017] (2) Mix 16 parts of acrylic resin with 20 parts of water to swell the resin to obtain a resin premix;
[0018] (3) Mix the graphene premix with the resin premix, add 6 parts of BYK wetting and dispersing agent, and 5 parts of tricarboxymethylpropane glycidyl ether, and stir evenly to obtain a finished product.
