摘　　要：在干旱半干旱地区高效蓄集可利用水资源已成为缓解水资源短缺的一种重要途径。针对储水设施容易发生渗漏问题,该文以红黏土为主要原料,添加高分子羧甲基纤维素钠(sodium carboxyl methyl cellulose,CMC)制备红黏土防水渗漏材料。采用扫描电子显微镜(SEM)、傅里叶红外光谱(FT-IR)、粒径分析仪和X射线衍射仪(XRD)等对材料的结构进行了分析和表征,并研究了材料的防渗水性能。结果表明:添加CMC对黏土材料的防渗漏性有很大的提高,当CMC的添加量为红黏土质量的1.20%时,材料的防渗水效果最佳,在1000h无水渗出。红黏土防渗漏材料对环境无毒无污染,原材料廉价易得,具有很大的实际应用价值。Better use of scarce water resources in arid and semi-arid areas has become an important way to alleviate water shortage. In the research,a novel processing method was proposed to solve water storage prone to leakage problem. The natural red clay was designed as main material,mixed with sodium carboxyl methyl cellulose（ CMC） to prepare clay seepage prevention materials. The structure of the material was analyzed and characterized by SEM,FT-IR,Particle size distribution tester and XRD,and the impermeability of the material was also studied. The experiment results showed that addition of CMC to the red clay material has a great improvement in the anti-leakage. When the mass ratio of CMC to clay is 1. 20%,the effect of anti-seepage is the best. This material can be degraded,without secondary pollution and environment-friendly. The material possesses great practical application value due to the raw materials are cheap and easy to obtain.
