摘　　要：将水杨酸钠作为苯酚和间苯二酚的替代品,形成了水杨酸钠/乌洛托品低毒性的有机交联体系。选用疏水改性聚丙烯酰胺与水杨酸钠/乌洛托品交联剂的水凝胶体系,研究了其成胶条件及性能。实验表明,该体系成胶时间、强度可控,能够将物理缔合与化学交联形成协同作用,同时该体系适用范围广,在高速剪切破坏下成胶强度仍能保持较大的比例。Sodium salicylate as a substitute for phenol and resorcinol, forming the low toxicity of organic cross-linking system consist of salicylic acid sodium/urotropine. The water gel consist of hydrophobic modified polyacrylamide as polymer and sodium salicylate/urotropine as cross-linker, study the formation conditions and performance of gel. The result show that, the gel can adjust formation time and strength, and synergy of physical association and chemical cross-linking can be embodied in the gel, the gel can be ap-plied in wide range and gel strength can remain recovery even after high speed shear.
