一种兼具黏土稳定和絮凝的高电荷密度两亲高分子

A High Charge Density Amphiphilic Polymer with Both Clay Stability and Flocculation

设计合成了带有高电荷密度和疏水链的聚合物PASC8,作为一种新型的阳离子黏土稳定剂,并对其进行防膨、絮凝及表面张力的性能测试评价。通过离心法、XRD、Zeta电位、浊度和表面张力测试,表明PASC8的黏土稳定剂防膨性能良好,其低浓度的絮凝效果优于传统防膨剂,且具有表面活性。

The polymer PASC8 with high charge density and hydrophobic chain was designed and synthesized as a new type of cationic clay stabilizer, and the performance of anti-swelling, flocculation and surface tension was tested and evaluated. Through centrifugal method, XRD, Zeta potential, turbidity test and surface tension test, research results show that PASC8 clay stabilizer has good anti-swelling performance, and its flocculation ability at low concentration is better than that of traditional anti-swelling agent, and its surface activity is high.
