Embodiment 1

[0027] 23.6kg of water, 25kg of 20% aliphatic polyoxyethylene ether aqueous solution, 1.5kg of triethanolamine, 1.5kg of diethanolamine, and 42kg of carbon black were mixed for wetting and pre-dispersion, and stirred for 1 hour at a stirring speed of 1000 rpm to obtain Soak the raw material.

[0028] Mix 0.1kg of methylisothiazolinone, 0.2kg of silicone defoamer, 0.1kg of n-octylisothiazolinone, 2kg of diethylene glycol and 1kg of nonionic polyurethane ether, and stir first , stirred for 0.5h, and the stirring speed was 1800 rpm to complete high-speed dispersion. A high-speed dispersion mixing aid is obtained.

[0029] Then add the high-speed dispersed mixing aid into the stirred soaking raw material, the stirring time is 0.5h, and the stirring speed is 600 rpm. Then use a vertical sand mill for sand grinding at a speed of 400 L / h until the particle size reaches below 10 μm to obtain an environmentally friendly water-based color paste with good dispersion performance.

Embodiment 2

[0031] Mix 38kg of water, 23kg of 20% aliphatic polyoxyethylene ether aqueous solution, 2kg of triethanolamine, 3kg of water-based acrylic acid, and 35kg of carbon black for wetting and pre-dispersion, and stir for 2 hours at a stirring speed of 1200 rpm Minutes, to obtain infiltrated raw materials.

[0032] Mix 1kg of diethylene glycol, 0.2kg of hydroxyethyl fiber thickener, 0.4kg of silicone defoamer, 0.4kg of carbendazim, 0.1kg of water-based polyurethane thickener and 1kg of nonionic polyamine Ethyl ether is mixed, first stirred, stirred for 40 minutes, the stirring speed is 2000 rpm, and high-speed dispersion is completed. . A high-speed dispersion mixing aid is obtained.

[0033] Then add the high-speed dispersed mixing aid to the stirred soaking raw material, the stirring time is 50 minutes, and the stirring speed is 800 rpm. Then use a vertical sand mill for sand grinding at a speed of 400 L / h until the particle size reaches below 10 μm to obtain an environmentally ...

Embodiment 3

[0035]Mix 48kg of water, 28kg of 20% aliphatic polyoxyethylene ether aqueous solution, 4kg of diethanolamine, 10kg of water-based polyurethane, and 30kg of carbon black for wetting and pre-dispersion, and stir for 1.5 hours at a stirring speed of 1300 rpm Minutes, to obtain infiltrated raw materials.

[0036] Mix 0.25kg of methylisothiazolinone, 3kg of diethylene glycol, 0.4kg of hydroxyethyl fiber thickener, 0.15kg of water-based polyurethane thickener and 3kg of nonionic polyurethane ether, first Stir, stir for 35 minutes, and the stirring speed is 1900 rpm to complete high-speed dispersion. A high-speed dispersion mixing aid is obtained.

[0037] Then add the high-speed dispersed mixing aid into the stirred soaking raw materials, the stirring time is 55 minutes, and the stirring speed is 900 rpm. Then use a vertical sand mill for sand grinding at a speed of 400 L / h until the particle size reaches below 10 μm to obtain an environmentally friendly water-based color paste wi...
