Example Embodiment
[0041] Example 1:
[0042] Weigh 89 grams of epoxy acrylate and 40 grams of hydroxyethyl acrylate, put them into a laboratory sand mill jar, add 2 grams of polyaniline with stirring, and stir for 0.5 hours. Under stirring, add dispersant BYK163: 0.5g, talc 15g, calcium carbonate 30g, precipitated barium sulfate 15g, leveling agent BYK371: 0.5g, 2-hydroxy-2-methyl-1-phenylacetone 8g, stirred at 2500 rpm for 3 hours, sanded for 1 hour, filtered with 200 mesh filter cloth.
[0043] The coating was sprayed on a polished, degreasing, and derusted metal steel plate, leveled at 60°C for 2 minutes, irradiated with 3kw ultraviolet light, curing time 30 seconds, and the performance of the paint film was measured after curing. The results are shown in Table 1.
Example Embodiment
[0044] Example 2:
[0045] Weigh 80 grams of epoxy acrylate and 42 grams of cyclohexyl acrylate, put them into a sand mill tank, add 10 grams of polyaniline under stirring, and stir for 1 hour. Under stirring, add dispersant BYK163:1g, talc 15g, calcium carbonate 30g, precipitated barium sulfate 15g, leveling agent BYK371:1g, 2-hydroxy-2-methyl-1-phenylacetone 6 g, stirred at 2500 rpm for 0.5 hours, sanded for 5 hours, filtered with 200 mesh filter cloth.
[0046] The coating was sprayed on a polished, degreasing, and derusted metal steel plate, leveled at 60°C for 2 minutes, irradiated with 3kw ultraviolet light, curing time 30 seconds, and the performance of the paint film was measured after curing. The results are shown in Table 1.
Example Embodiment
[0047] Example 3:
[0048] Weigh 106 grams of epoxy acrylate and 50 grams of isobornyl acrylate, put them into a sand mill tank, add 20 grams of polyaniline with stirring, and stir for 2 hours. Under stirring, add dispersant BYK163: 3g, talcum powder 2g, calcium carbonate 5g, precipitated barium sulfate 3g, leveling agent BYK371: 3g, 1-hydroxycyclohexyl benzophenone 8g, at 2500 revolutions Stir at a speed of 1 hour / min, sand mill for 10 hours, filter with 200 mesh filter cloth.
[0049] Spray the paint on a polished, degreasing, and rust-removed metal steel plate, level it at 60°C for 2 minutes, irradiate with 3kw ultraviolet light, cure for 30 seconds, and measure its performance after the paint film is cured. The results are shown in Table 1. .
