Recipe details

Production Method

After preparing the above raw materials, add the formula (parts by mass) of the latex base paint to the cosolvent, dispersant, and defoamer in the water, stir evenly at low speed and slowly add the pigments and fillers, then disperse the pigments and fillers at high speed, and then sand until The fineness is less than 30μum, filter.

After the filtration is completed, under low-speed stirring, add wetting agent, defoamer, film-forming aid, emulsion to the above-mentioned dispersion slurry, and then add thickener to adjust the viscosity to 90~100KU, add pH adjuster to make the pH Value is 8.

According to the production technology of colored latex paint described in this technology, the toning color paste is composed of the color pastes PB-15:3 and PBK-7 of Shenzhen Oceanpower Company.

Inject them into the tinting machine in proportion, and after debugging, inject them together with the above-mentioned latex base paint into a special mixing machine for color paint to mix them evenly in a short time, generally 200~280s, preferably 200 ~ 250s.

Precautions

The range of the mass ratio of each component is: water 8~12, cosolvent 2~4, dispersant 0.

The tinting color paste is composed of Shenzhen Oceanpower's color paste PB-15: 3, PBK-7.

In the formula (parts by mass), it mainly plays the role of decoloring and reducing color saturation.

National standard color (GB/T 18922- 2002) 0572 colored architectural latex paint is blue, the contrast ratio should be 0.

For the selection and compatibility of emulsions, white pigments, dispersants, wetting agents, defoamers, preservatives, pH regulators, thickeners, and film-forming additives for interior wall coatings, please refer to "Yellow Interior Wall Latex Paint (1)" .
