Method of Preparing Particle Agglomeration Using Medium Size Rubber Latex

摘要

PURPOSE: Provided is a method for producing condensed particles using rubber latex having a middle particle size by adding unsaturated acid monomer containing copolymer latex to a synthetic rubber latex having a middle particle size. CONSTITUTION: The method includes the steps of mixing a synthetic rubber latex with a particle size of 1,500 to 2,500 angstrom, an anionic emulsifying agent, non-ionic emulsifying agent and a defoaming agent, while stirring to pretreat the synthetic rubber latex; mixing ion exchanging water and pH controller to a unsaturated acid containing copolymer latex having a solid content of 10 to 50 wt% to adjust the solid content of the copolymer latex to 1 to 10 wt% and the pH of 5 to 11; and adding the unsaturated acid containing copolymer latex treated as above into the pretreated synthetic rubber latex.
