中文摘要	土地沙漠化是当今世界面临的最大环境问题之一,采用固沙剂进行化学防治技术是沙漠化治理的主要途径之一,其优点是成本低,见效快,施工简便。通过以聚醚二元醇、甲苯二异氰酸酯(TDI)、二羟甲基丙酸(DMPA)、三羟甲基丙烷(TMP)、可溶性淀粉等为原料制备了内交联型可生物降解水性聚氨酯固沙剂,考察了可溶性淀粉用量对其性能的影响。结果表明:随着可溶性淀粉用量的增加,内交联型可生物降解水性聚氨酯固沙剂的粘度增加,粒径呈增大趋势,固沙剂对沙盘的保水效果得到提高,内交联型水性聚氨酯胶膜的生物降解性增强。通过实验制备的水性聚氨酯固沙剂,除具有固沙保水作用外,还可以生物降解,缓解固沙剂废弃物对环境造成的压力。
英文摘要	Desertification is one of the most severe environmental and social problems. Chemical prevention technology was an important method of desertification control, which is of low-cost, effective and simple for application. In this paper, a kind of networking biodegradable aqueous polyurethane sandy-soil stabilizer was synthesized by polyether glycol, toluene diisocyanate (TDI), dimethylolpropionic acid (DMPA), trimethylolpropane (TMP), soluble starch, and some other materials. The effects of the content of soluble starch on the property of the sandy-soil stabilizer were studied. The results showed that, while the content of soluble starch increased, the viscosity and the average particle size of the emulsion increased, the ability of water conservation and the biodegradation enhanced. From this experiment, aqueous polyurethane sandy-soil stabilizer was prepared, which not only good for sandy-soil stabilization and water retention, but also good for biodegradation after a long run, which was do well in environmental protection.
