    摘要： @ The water-swellable caulking material for water-leakage prevention is of the type formed from a composition comprising a rubbery polymer and a highly water-absorptive resin and useful in caulking a concrete construction joint. The caulking material is provided on the surface of a shaped body of the water-swellable composition with a coating film which is impervious to water at a substantially neutral pH but exhibits water-permeability when contacted with water at an alkaline pH such as an uncured concrete mixture so that the caulking material is prevented from premature or untimely expansion by swelling even when inadvertently contacted with water prior to application at the working site but capable of expanding promptly when contacted with an uncured alkaline concrete mixture.

    摘要翻译： 用于防止漏水的水溶胀性填缝材料是由包含橡胶状聚合物和高吸水性树脂的组合物形成的类型，并且可用于填塞混凝土结构接头。 填缝材料在水溶胀性组合物的成形体的表面上设置有在基本上中性pH下不透水的涂膜，但是在碱性pH下与水接触时具有透水性，例如未固化的混凝土 混合物，使得即使在施加于工作现场之前不经意地与水接触，也可以通过膨胀来防止填塞材料的过早或不合时间的膨胀，但是当与未固化的碱性混凝土混合物接触时能够迅速膨胀。

    摘要： A water-absorbing rubber composition comprising (A) a 1,3-diene rubber with a crystal or glass region content as measured at an ordinary temperature of 5-50% and (B) a highly water-absorbing resin dispersed in the said rubber, the said highly water-absorbing resin being a product of crosslinking of a polymer which contains as monomer component thereof at least 40 mole percent of an a,p-unsaturated compound containing 1 or 2 groups each selected from the class consisting of a carboxyl group and a group convertible to a carboxyl group with at least one crosslinking agent selected from the class consisting of a polyfunctional epoxy compound and a polyamine, the resin being in the form of a powder capable of passing through a 20-mesh Tyler screen and absorbing 20-500 times its own weight of distilled water. The composition can absorb water rapidly and produce a high swelling pressure, and has good durability in the swollen state.

    摘要： A water-swellable adhesive water stop having improved workability and high water-stopping power comprises a shaped and vulcanized rubber composition comprising: (A) a butyl rubber; (B) a highly water-absorptive resin; (C) an inorganic water-absorbent; (D) a tackifier; (E) a plasticizer; (F) a vulcanizing agent; and, optionally, (G) a basic filler each in a limited amount relative to the component (A). The water stop has a tensile strength in the range from 1 to 30 kgf/cm , 100% elastic modulus in the range from 1 to 4 kgf/cm , ultimate elongation at break of at least 300% and degree of swelling in water in the range from 150 to 500% by weight after immersion in water for 21 days at 23 C.
