Abstract

PURPOSE: The titled cheap, non-toxic water-stoppable material composition with excellent swelling property and durability, useful for a civil work, etc. which is obtd. by compounding a rubber primarily composed of a reclaimed rubber with a specified proportion of a silicate, bentonite and a plasticizer.
CONSTITUTION: A rubber component primarily consisting of a reclaimed rubber such as a reclaimed butyl rubber or tire rubber and contg. about 10W30% uncrosslinked rubber such as natural, butyl or halogenated butyl rubber, is compounded with 10W20% silicate such as silica, water glass or calcium silicate, 10W60% bentonite and 10W40% plasticizer such as a paraffin base mineral oil, stearic acid or cottonseed oil, to obtain the purpose water swelling, water-stoppable material composition. The composition obtd. is not deteriorated in degree of swelling by repeated swelling and drying or with hard water and never deteriorate nor corrode for a long period of time.
