When the initial polymerization monomer input amount accounts for about 10% of the total monomer amount, a polymerization process with smaller initial polymerization monomer input amount is adopted, and the produced emulsion has stable quality but poor film forming property and adhesiveness. When the initial polymerization monomer input amount is 100%, the one-time feeding will result in large heat release and reaction fluctuation during initial polymerization, so that the mixing effect will be poor, and the quality of the produced latex will be reduced, so that a polymerization process is generally adopted in which the initial polymerization monomer accounts for more than 30%.

However, when the polymerization process of the initial polymerization monomer accounting for more than 30% is adopted, the stirring device rotates around the stirring shaft when the reaction material is stirred, the fluid is in a tangential flow state, the liquid level in the central part is lowered, so that a vortex is formed, and at the moment, the flow rate of the material sucked from the periphery of the blade to the blade area is small, so that the mixing effect of the reaction material in the initial polymerization stage is reduced, the quality of the carboxyl styrene-butadiene latex is influenced, and therefore, the improvement is needed.
