Examples
Embodiment 1
[0071] Example 1 - Coating 1
[0072] Disperse 0.01 g of benzyl alcohol, 0.01 g of pyrogallol, and 2.0 g of graphene slurry in 0.6 L of acetone, and sonicate for 1 hour. Add the obtained dispersion slurry to 50 g of acrylic resin, then add 20 mL of xylene, 0.1 g of BYK348, 0.1 g of BYK085, and 0.3 g of diatomaceous earth in sequence, and stir at 1500 r / min for 30 min to obtain Coating 1. Coating 1 is sprayed onto the PP board for its comprehensive physical properties and surface morphology see figure 2 .
[0073] result:
[0074] According to GB / T 16906, GB / T 1720 and GB / T 1771, the results are shown in Table 1 below. The surface resistivity, salt spray resistance and adhesion of coating 1 all meet the requirements.
Embodiment 2-
[0075] Example 2 - Coating 2
[0076] Disperse 0.01g of Triton X-100, 0.01g of pyrogallol, and 4.0g of graphene slurry in 1.0L of acetone, and ultrasonically disperse for 1 hour. Add the obtained dispersion slurry to 70g of acrylic resin, then sequentially add 28mL of xylene, 0.2g of BYK351, 0.1g of BYK085, 0.5g of diatomaceous earth, and stir at 1500r / min for 30min to obtain coating 2.
[0077] result:
[0078] The inspection was conducted according to GB / T 16906, GB / T 1720, and GB / T 1771. The results are shown in Table 1 below. The surface resistivity, salt spray resistance, and adhesion of coating 2 all meet the requirements.
Embodiment 3-
[0079] Example 3 - Coating 3
[0080] Disperse 0.01g of Triton X-100, 0.01g of pyrogallol, and 2.0g of graphene slurry in 0.6L of acetone, and ultrasonically disperse for 1 hour. Add the obtained dispersion slurry to 60g of acrylic resin, then add 15mL of xylene and 10mL of absolute ethanol, 0.1g of leveling agent (BYK348), 0.1g of defoamer (BYK085), 0.3g of diatomaceous earth, 1500r / min and stirred for 30 min to obtain coating 3.
[0081] result:
[0082] The inspection was conducted according to GB / T 16906, GB / T 1720, and GB / T 1771. The results are shown in Table 1 below. The surface resistivity, salt spray resistance, and adhesion of coating 3 all meet the requirements.
