Embodiment 1
[0024] According to the formula weight ratio, add 28.5 parts of mixed solvent into the dispersion tank, add 50 parts of 70% solid-containing alkyd resin, add 6 parts of DISPERBYK-2050 color paste dispersant and stir evenly, slowly add 15 parts of translucent Guifei Hongshengsheng Sodium powder, 0.2 parts of defoaming agent, 0.3 parts of anti-sedimentation agent, then disperse at a high speed of 1000-1200r / min for 45-60 minutes, and then go to a horizontal sand mill to grind 5-8 times until the fineness of the color paste is reached. When the particle size reaches the requirement of ≤5μ, it is transferred to the paint mixing bucket for defoaming and viscosity adjustment, and is filtered and packaged to obtain chaise red pulp.
Embodiment 2
[0026] According to the weight ratio of the formula, add 17 parts of mixed solvent into the dispersion tank, add 65 parts of 70% solid alkyd resin, stir evenly, add 1 part of matting powder, 0.2 parts of dispersant, disperse at high speed for 30-40 minutes, and at low speed Add 15 parts of Royal Concubine Red Paste, 0.3 parts of titanate-modified silicone chelating leveling agent, 0.3 parts of fluorine-modified acrylic leveling agent, 0.3 parts of modified siloxane defoamer, and 1.2 parts of anti-settling agent , stirred and passed the test, filtered and packaged to obtain the translucent Guifei Hongshengshengna odor-cleaning type polyurethane wood lacquer A component.
Embodiment 3
[0028] Add 40 parts of TDI / TMP adduct, 30 parts of HDI trimer, and 30 parts of mixed solvent into the dispersion barrel and stir evenly. After passing the test, filter and pack to obtain translucent chaise longan and clean taste polyurethane wood paint B components.
[0029] Mix the paint according to the ratio of component A: component B = 1:0.5, and add thinner to adjust the viscosity to spray or brush.
