摘要：Polymer agglomeration has a good application prospect in enlarging the particle size of polybutadiene latex (PBL), which has attracted considerable attention in the field of agglomeration. However, the agglomeration process of PBL under different agglomeration conditions has not been studied. In this study, a coaxial cylindrical viscometer was used to perform agglomeration experiments. The different stages of PBL agglomeration can be determined by observing the viscosity changes, due to the particle size of nanoparticles in emulsion is an important factor affecting its viscosity. In this communication, the effect of the content of agglomerating agent, agglomeration temperature and shear rate on the agglomeration process and particle size of PBL were studied. It was found that with the increase of the content of agglomerating agent, the time required to reach the adsorption saturation and complete the entire agglomeration of PBL decreased. High temperature can accelerate the agglomeration process of PBL, but when the temperature is higher than 60 ℃, the stability of the emulsion will be destroyed. The increase of the shear rate can reduce the time required for the adsorption saturation, and the particle size of PBL decreases with the increase of the shear rate for the agglomeration system with the 12% content of agglomerating agent. This study not only provides a new perspective for the study the agglomeration process of PBL, but also helps to precisely control the agglomeration conditions of PBL and improve the agglomeration efficiency. ? 2024, The Authors.
