为探讨聚丙烯酸钠吸水性树脂的粘附性能,设计了一种对其粘附性能的测定方法并进行了测试及表征,讨论了不同实验条件对树脂粘附性能的影响.结果表明,该吸水树脂的粘附性能随吸水量、初始压力和分离速率的增加具有一定的变化规律,并根据高分子结构理论、粘接的机械互锁理论和应力松弛等理论进行了解释.%In order to study the adhesion property of poly(sodium acrylate) absorption resin, a new test technique for adhesion property in swollen state was designed. Then influencing factors of the resin's adhesion property were discussed. The results indicate that adhesion property have some variation with the increase of water absorption, initial pressure and separation rate, and the phenomenon can be explained by the theory of polymer structure, mechanical interlock and stress relaxation.
