Embodiment 1
[0028] Include following raw material in formula and each raw material weight ratio is:
[0029] Acrylic 65%
[0030] Amino resin 22%
[0031] Pigment 0%
[0032] Adhesion Promoter 2%
[0033] Leveling agent 0.3%
[0034] Butyl acetate 7%
[0035] Diacetone Alcohol 3.7%,
[0036] When the amount of pigment is 0, it means that there is no color in the paint, and the resulting paint is a clear varnish. Put the above-mentioned materials into the stirring tank according to the paint making formula, the stirring speed is generally 200-400r / min, and the stirring time is 5 minutes. After the materials are evenly dispersed by the disperser, the performance index is inspected. After passing the inspection, filter and measure ,Package.
Embodiment 2
[0038] Include following raw material in formula and each raw material weight ratio is:
[0039] Acrylic resin 68%
[0040] Amino resin 20%
[0041] Pigment 3%
[0042] Adhesion Promoter 1%
[0043] Leveling agent 0.1%
[0044] Butyl acetate 5.9%
[0045] Diacetone Alcohol 2%,
[0046] The pigment used in this embodiment is aluminum silver paste. First, soak the aluminum powder in butyl acetate for three hours to prepare aluminum silver paste, then put the resin, solvent, and additives into the stirring tank according to the above weight ratio, stir evenly through the disperser, and soak and disperse before adding Aluminum silver paste, and disperse and stir at low speed (200-400r / min), stir for 5 minutes. Finally, color matching, inspection, filtration, measurement and packaging are carried out.
Embodiment 3
[0048] Include following raw material in formula and each raw material weight ratio is:
[0049] Acrylic 62%
[0050] Amino resin 22%
[0051] Pigment 5%
[0052] Adhesion Promoter 2%
[0053] Leveling agent 0.2%
[0054] Butyl acetate 4.8%
[0055] Diacetone Alcohol 4%,
[0056] The pigment used in this example is a mica pigment. First, soak the mica powder in butyl acetate for three hours to prepare the mica pigment, then put the resin, solvent, and additives into the stirring tank according to the above weight ratio, and stir evenly through the disperser, then add the soaked and dispersed ones Mica pigment, and disperse and stir at low speed (200-400r / min), stir for 5 minutes. Finally, color matching, inspection, filtration, measurement and packaging are carried out.
