Example Embodiment
[0032] Example 1
[0033] A large-color-dot sand-in-water basic paint, which is obtained through the following processing steps:
[0034] According to the dosage shown in Table 1, add deionized water to the mixer, and add dispersant, defoamer, antifreeze, film-forming aid, titanium dioxide, kaolin, and ethyl hydroxyl at a rotation speed of 300r / min. Ethyl cellulose and methyl ethyl hydroxyethyl cellulose, stir and disperse for 8 min; add pH adjuster, stir and disperse for 20 min at a speed of 1200 r / min, to obtain mixture A; at a speed of 800 r / min, Add emulsion, antiseptic, 10wt% protective glue solution, thickener and 80-120 mesh quartz sand to the mixture A in sequence, stir and disperse for 8min at a rotating speed of 800r / min, to obtain a large color dot sand-in-water basic paint.
Example Embodiment
[0035] Example 2
[0036] A large-color-dot sand-in-water basic paint, which is obtained through the following processing steps:
[0037] According to the dosage shown in Table 1, add deionized water to the mixer, and add dispersant, defoamer, antifreeze, film forming aid, titanium dioxide, kaolin, and ethyl hydroxyl at a speed of 400r / min. Ethyl cellulose and methyl ethyl hydroxyethyl cellulose, stir and disperse for 5 min; add pH adjuster, stir and disperse for 15 min at a speed of 1300 r / min to obtain Mixture A; at a speed of 900 r / min, Add emulsion, preservative, 10wt% protective glue solution, thickener and 80-120 mesh quartz sand to the mixture A in sequence, stir and disperse for 5 minutes at a rotation speed of 900 r / min, to obtain a large color dot sand-in-water base paint.
Example Embodiment
[0038] Example 3
[0039] A large-color-dot sand-in-water basic paint, which is obtained through the following processing steps:
[0040] According to the dosage shown in Table 1, add deionized water to the mixer, and add dispersant, defoamer, antifreeze, film-forming aids, titanium dioxide, kaolin, and ethyl hydroxyl at a speed of 500r / min. Ethyl cellulose and methyl ethyl hydroxyethyl cellulose, stir and disperse for 10 min; add pH adjuster, stir and disperse for 25 min at a speed of 1500 r / min to obtain Mixture A; at a speed of 1000 r / min, Add emulsion, preservative, 10wt% protective glue solution, thickener and 80-120 mesh quartz sand to the mixture A in sequence, stir and disperse for 10 minutes at a rotation speed of 1000 r / min, to obtain a large color dot sand-in-water base paint.
