Embodiment 1
[0030] (1) Raw material quality
[0031] Bright color resin: 100 kg
[0032] Liquid SBS modifier: 4 kg
[0033] Inorganic pigment: 1 kg of 307 molybdenum chrome red pigment or 1 kg of SGC-M chrome green pigment
[0034] Pigment dispersant: 0.003 kg polycarboxylate sodium salt or 0.003 kg polyacrylate ammonium salt
[0035] (2) Preparation process (such as figure 1 shown)
[0036] 1. Add the bright-colored resin emulsion into the reactor, keep the temperature of the reactor at 20°C to 30°C, and start stirring;
[0037] 2. Add phosphoric acid to the reaction kettle, adjust the pH of the system to 2.5-4.5, and stir to make the system evenly mixed;
[0038] 3. Add liquid SBS modifier to the reaction kettle, and continue to stir until the system is evenly mixed;
[0039] 4. Add inorganic pigment 307 molybdenum chrome red pigment or SGC-M chrome green pigment to the system, and at the same time add pigment dispersant polycarboxylate sodium salt or polyacrylic acid ammonium sal...
