Example Embodiment
[0029] Example 1
[0030] The preparation process of water-based industrial dip coating according to the above formula:
[0031] Dispersion: Add water-based alkyd modified acrylic resin, deionized water, neutralizer, wetting and dispersing agent, defoamer, drier, high pigment carbon black, anti-rust pigment, and filler into the mixing tank according to the formula amount. Medium, speed 800r / min, dispersion 15min;
[0032] Grinding: Grind the dispersed slurry on a sand mill, and check the fineness every 15 minutes until the fineness of the slurry is ≤30μm;
[0033] Dilution: Put the slurry with qualified grinding fineness into the paint mixing container and adjust to the required viscosity to obtain the water-based industrial dipping paint.
Example Embodiment
[0034] Example 2
[0035] The preparation process of water-based industrial dip coating according to the above formula:
[0036] Dispersion: Add the water-based alkyd modified acrylic resin, deionized water, neutralizer, drier, defoamer, wetting and dispersing agent, high pigment carbon black, anti-rust pigment, and filler to the mixing tank according to the formula amount. Medium, speed 800r / min, dispersion 15min;
[0037] Grinding: Grind the dispersed slurry on a sand mill, and check the fineness every 15 minutes until the fineness of the slurry is ≤30μm;
[0038] Dilution: Put the slurry with qualified grinding fineness into the paint mixing container and adjust to the required viscosity to obtain the water-based industrial dipping paint.
[0039] The above-mentioned Example 1 can achieve the required fineness of 30 μm after 1.5 hours of grinding, and the required fineness of 30 μm after 2 hours of grinding in Example 2.
