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
