Abstract
A method for manufacturing a large-particle-size styrene butadiene latex includes mixing a first styrene-butadiene latex with a polyacrylate agglomerating agent and an inorganic salt solution to allow the first styrene-butadiene latex to undergo an agglomeration process, so as to obtain a second styrene-butadiene latex that has a particle size larger than that of the first styrene-butadiene latex. The polyacrylate agglomerating agent is present in an amount ranging from 0.1 parts by weight to 1 part by weight and an inorganic salt in the inorganic salt solution is present in an amount of 0.25 parts by weight, based on 100 parts by weight of the first styrene-butadiene latex. The first styrene-butadiene latex is stable and not susceptible to emulsion breaking during the agglomeration process.
