[0027] The present invention also provides a method for preparing the above-mentioned multicolor base paint emulsion with excellent performance, comprising the following steps:
[0028] 1) Preparation of base material liquid A: Add 10-30 parts of deionized water and 0.5-1 part of surfactant to the reaction kettle with agitator, condenser and constant flow pump feeding device, and heat up to the temperature in the kettle Reach 80-90°C;
[0029] 2) Preparation of monomer solution B: 5-10 parts of methyl methacrylate, butyl acrylate, styrene, acrylic acid, functional monomer, remaining surfactant, and deionized water in a formula amount under normal temperature and pressure Mix into a uniform solution and stir for 10-30 minutes for later use;
[0030] 3) Preparation of initiator solution C: add the formula amount of persulfate into the remaining deionized water, stir to dissolve;
[0031] 4) When the temperature in the kettle reaches 80-90°C, add 1-5 parts of step 2) to prepare...
