粘土颗粒对疏水缔合聚合物水溶液性能的影响

EFFECTS OF CLAY PARTICLES ON THE BEHAVIORS OF HYDROPHOBICALLY ASSOCIATIVE POLYMER SOLUTION

摘要: 通过测试在少量钠基膨润土存在下疏水缔合聚合物溶液的流变性能，发现适量的粘土颗粒使缔合聚合物溶液缔合程度明显加大，所得到的缔合聚合物-粘土分散体系显示出比单纯缔合聚合物溶液有更低的临界缔合浓度，更优良的抗温性及剪切稀释性，但在NaCl存在下，“反盐效应”不明显。在实验结果基础上，探讨了粘土颗粒对缔合聚合物溶液性能的影响规律及两者之间的相互作用机理。

Abstract: Measuring the rheological properties of New Associative Polymers (NAPs) solution in the presence of a little bentonite, a greater associative behavior was found. When temperature raised and the concentration of NaCl increased, the new associative polymers
