[0036] Example:
[0037] A preparation method of soap-free synthetic water-based acrylic dispersion resin, comprising the following steps:
[0038] S1, add the deionized water of 250kg to the reactor, stir with the rotating speed of 25 rev / min, add the emulsifier COPS-1 of 0.33kg, and rinse the emulsifier COPS-1 remaining in the container with the deionized water of 2.53kg In the reactor, then the reactor is warming up to 75°C;
[0039] S2, the ammonium sulfate of 0.11kg and the deionized water of 3.8kg are added to the initiator shot tank, and the ammonium sulfate remaining in the container is rinsed into the reactor with the deionized water of 1.27kg, and the initial initiator is made for subsequent use;
[0040] S3, add 45.34kg of deionized water to the monomer tank, stir at a speed of 50 rev / min, add 0.98kg of emulsifier COPS-1 to blend and disperse uniformly;
[0041] S4, the acrylic acid of 18kg, the diacetone acrylamide of 7.29kg, the butyl acrylate of 53kg, the two m...
