Abstract

PURPOSE: The titled composition that is produced by mixing a rubber mainly containing polyisobutylene, a silicate as a filler and a plasticizer in a specific proportion, thus showing good water-proofing properties, because it completely clots gaps and holes in structures and has a some level of extensiblity.
CONSTITUTION: The objective composition is obtained by combining (A) 10W 40pts.wt. of a rubber minly composed of polyisobutylene, which may be mixed with natural or synthetic rubber, with (B) 10W20pts of a silicate as a filler such as hydrated silicic acid or calcium silicate, (C) 10W60pts of bentonite and (D) 10W 40pts of a plasticizer such as paraffinic mineral oil or polybutene.
EFFECT: Water leakage can be completely prevented, because, even when gaps would be formed on the part to be stopped, after or during the operation, and water would come thereto, the material absorbs water to expand and fill the gaps.
USE: Waterstopping between segments in a tunnel or joint parts in Hume concrete pipes.
