水性丙烯酸酯共聚物交联体系的流变性

Rheological Properties of Crosslinkable Water-Borne Acrylate Copolymers

摘要: 用旋转粘度计研究了甲基丙烯酸甲酯／丙烯酸丁酯／丙烯酸三元共聚物水性交联体系的流变性，考察了树脂含量、金属鳌合物含量和氨水水化对其流变性的影响。结果表明：三元共聚物水性交联体系呈非牛顿流体流变行为，具有剪切变稀特性；随树脂含量或鳌合物含量增加，体系的增稠能力得以增强；水化不仅可改善体系的增稠性能，而且可增强体系的非牛顿流变性。

Abstract: The rheological properties of crosslinkable water-borne acrylate resin based on the terpolymer of methyl-methacrylate, butyl acrylate and acrylate acid were studied with a rotation viscosimer. The factors investigated include the resin content, chelate co
