Abstract

ABSTRACT This work aimed to study the use of sodium perborate as a foaming agent in the production of porous metakaolin-based geopolymer. The influence of sodium perborate foaming agent on physical properties, mechanical properties, and thermal conductivity was focused. The results revealed that the porosity and pore size increased with an increment of the additions of sodium perborate from 0.5 to 2.0 wt.%. The obtained porous geopolymers showed compressive strength of 5–6 MPa and thermal conductivity in the range of 0.22–0.32 W/mK. The addition of sodium perborate produced porous geopolymer with acceptable compressive strength and thermal conductivity.

过硼酸钠改性偏高岭土基多孔地质聚合物的制备与性能

摘要本工作旨在研究过硼酸钠作为发泡剂在多孔偏高岭土基地质聚合物生产中的应用。重点研究了过硼酸钠发泡剂对泡沫材料物理性能、力学性能和导热性能的影响。结果表明，随着过硼酸钠添加量从0.5 wt.%增加到2.0 wt.%，多孔地质聚合物的孔隙率和孔径都会增加。所得多孔地质聚合物抗压强度为5–6 MPa，热导率在0.22–0.32 W/mK范围内。过硼酸钠的加入产生了具有可接受的抗压强度和导热性的多孔地质聚合物。
