摘要： A water swellable rubber composition comprising (a) a non-water swellable base rubber, (b) an ethylene oxide based hydrophilic elastomer having from zero up to and including 20 mole % of a crosslinkable curable functional group, and (c) a water swellable non-elastomeric material. The composition has excellent water swell characteristics under prolonged exposure to high temperature and various electrolyte solutions (strongly saline as well as acid conditions) and is particularly suitable for oil field applications. When the ethylene oxide based hydrophilic elastomer (b) has from zero to less than 5 mole % of crosslinkable functional group, the amount of (b) is between about 30 parts and 300 parts by weight based on 100 parts by weight of the base rubber (a) and the amount of (c) is between about 20 parts and 200 parts by weight based on 100 parts by weight of the base rubber (a), the composition is characterized by good shape retention after undergoing constrained swell, as well as a high degree of constrained swell at elevated temperatures in different saline concentrations.
摘要翻译：一种水溶胀性橡胶组合物，其包含（a）非水可溶胀基础橡胶，（b）具有至多且包含20摩尔％交联性可固化官能团的环氧乙烷基亲水性弹性体，和（c）水可溶胀非弹性材料。该组合物在长时间暴露于高温和各种电解质溶液（强盐水以及酸性条件）下具有优异的水溶胀特性，特别适用于油田应用。当环氧乙烷基亲水弹性体（b）的交联性官能团为零至小于5摩尔％时，相对于100重量份的基础橡胶，（b）的量为约30重量份〜300重量份（a）和（c）的量基于100重量份的基础橡胶（a）为约20重量份至200重量份，该组合物的特征在于经受约束膨胀之后具有良好的形状保持性，以及在不同盐水浓度的高温下高度受限的膨胀。
