Embodiment 1
[0024] According to the formula weight ratio, add 22.5 parts of mixed solvent into the dispersion tank, add 50 parts of 70% solid-containing net-flavored alkyd resin, add 7 parts of TEGO-610S color paste dispersant and stir evenly, slowly add 20 parts of translucent acid branch color Raw amba powder, 0.2 part of defoamer, 0.3 part of anti-sedimentation agent, and 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 color paste When the fineness and particle size reach the requirement of ≤5μ, it is transferred to the paint mixing tank for defoaming and viscosity adjustment, and filtered and packaged to obtain the rosewood color paste.
Embodiment 2
[0026] According to the formula weight ratio, add 19.5 parts of mixed solvent into the dispersion tank, add 60 parts of 70% solid-containing alkyd resin, stir evenly, add 2.5 parts of matting powder, 0.3 parts of dispersant, disperse at high speed for 30-40 minutes, and disperse at low speed Add 16 parts of acid branch color paste, 0.3 parts of titanate-modified silicone chelating leveling agent, 0.2 parts of fluorine-modified acrylic leveling agent, 0.2 parts of modified silicone defoamer, and 1 part of anti-settling agent under stirring. After stirring and passing the test, it was filtered and packaged to obtain the first component of translucent rosewood-colored raw amba net-odour type polyurethane wood lacquer.
Embodiment 3
[0028] Add 40 parts of TDI / TMP adduct, 30 parts of HDI trimer, and 30 parts of mixed solvent into the dispersion tank and stir evenly. After passing the test, filter and pack to produce translucent rosewood-colored and amba-clean odor type polyurethane woodware Paint B component.
[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.
