| 摘 要： | 近二十多年来,如何提高乳胶产品固含量一直是乳液制备工作所追求的重要目标之一。相对于传统乳液而言,高固含量具有更大的分散相体积分数,甚至达到70%(wt)以上。因此,高分散相体积分数状态下的流变性能一直成为高固含量乳液制备过程中的瓶颈。粒子尺寸及其分布在粘度控制过程中起着至关重要的作用。本文从单分散体系、多元分散体系和宽粒径分布体系三个方面,详细评述了近几年高固含量乳液流变研究领域的数学建模和实验研究。并对高固含量乳液流变性能研究的发展进行了展望。

| Abstract: | One of the major challenges in emulsion polymerization over the past two decades has been the ability to increase the solid content of emulsion products.In contrast to the conventional emulsions,High-solid-content latex has a large volume fraction of dispersed phase,even greater than 70% in weight.Rough rheology behavior is always the restricting factors existed in preparation process.Colloid particle size and particle size distribution(PSD) play an important role in the control of viscosity.The present rev... |
