摘要
对近年来国内外吸水树脂堵漏材料的结构和种类进行了综述,分析了膨胀倍率的影响因素,概述了目前吸水堵漏材料延时膨胀的方法如包裹法、接枝疏水性单体和采用非水携带液等。总结了吸水树脂类堵漏材料存在的问题,并提出了研究建议。
In this paper,the structure and species of water absorbent resins used as lost-control materials（LCM） was reviewed.The effects of equilibrium swelling ratio were analyzed.Moreover,the methods for delayed expansion,such as coating,grafting hydrophobic monomer,using anhydrous liquid as the carrying fluid,etc,were summarized.Finally,the current problems and research suggestions of water absorbent polymers for LCM were proposed.
