Abstract

PURPOSE: To provide the titled compsn. which is nontoxic and in which the strength reduction, the deterioration and the putrefaction of the compsn. during use do not occur, containing, as essential ingredients, an uncrosslinked rubber or a partially crosslinked rubber, a specified amount of white carbon and a specified amount of a plasticizer.
CONSTITUTION: There is provided a water-swellable waterstop material compsn. containing, as essential ingredients, (A) an uncrosslinked rubber and/or a partially crosslinked, (B) 18W45wt% (based on the weight of the compsn.) of white carbon and (C) 13W40wt% (based on the weight of the compsn.) of a plasticizer. As the uncrosslinked rubber of the component (A), a butyl rubber, a halogenated butyl rubber or an ethylene-propylene rubber is preferred. As the component (B) used, silicic anhydride or hydrated silicic acid is preferred. As the component (C), a synthetic plasticizer such as an ester or a polyamide, or a rubber softener such as a mineral oil softener is used.
