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 。
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/clay solution showed lower critic associative concentration(C *) and a more powerful ability to keep or even increase the viscosity of the solution than that of pure associative polymer solution without clay. But anti-salt-effect was not evident at the exist of NaCl. Finally, based on the results of the experiment, both the effect of the clay particles on the associative polymers solution and the interaction between New Associative Polymers (NAPs) and clay particles were discussed.
