2. The production process of the flat color base paint of the polymer water dispersion system:
(1) Prepare raw materials according to the paint formula;
(2) Add ethylene glycol monopropyl ether into the cylinder of the paint dispersing mixer, start the mixer (speed 300r/min), and slowly add triethylamine, 3.8kg defoamer, surfactant, chlorinated paraffin, Stir and mix the polymer dispersion, calcium carbonate, mica powder, and pigments evenly;
(3) Increase the speed of the mixer to 1000r/min, and stir for 30 minutes;
(4) Grind until the fineness is qualified, reduce the speed, add the remaining raw materials, and stir evenly;
(5) Shutdown, filtration, discharge, barreling, storage.
