摘　　要：选用不同硅烷偶联剂对凹凸棒土(ATP)进行改性,利用ATP的孔道作为保温单元,制备新型柔性饰面砖。通过X射线衍射(XRD)和扫描电镜(SEM)对改性前后的ATP进行表征,通过自制保温测试装置测试柔性饰面砖的保温隔热性能。研究结果表明,改性后ATP表面被有机改性剂包覆,当m(KH-550)/m(ATP)为0.008时,所制备柔性饰面砖的保温隔热性能最优。当KH-550/ATP填料量为35%时,柔性饰面砖的保温性能最佳。The flexible decorative brick was prepared using porous attapulgite（ATP） as thermal insulation unit,which was modified by different silane coupling agent.The unmodified and modified ATP was characterized by X-ray diffraction （XRD） and scanning electron microscopy（SEM）,and the thermal insulation performance of flexible decorative brick was test by self-made device.The results show that the modified ATP is covered with organic modifier,and it has optimized thermal insulation performance when m （KH-550）/m（ATP）is 0.008.The best thermal insulation effect is obtained with a KH-550/ATP filling content of 35％.
