ABSTRACT:
There is disclosed a water-preventing sealant with plasticity, comprising 10 to 60% by weight of a gelled base oil (i) obtained by conducting a gelling reaction of a mixture of 100 parts by weight of an oil, 10 to 100 parts by weight of a fatty acid and a metal hydroxide or oxide contained in an amount sufficient to convert the fatty acid into a metal salt, and 40 to 90% by weight of at least one member (ii) selected from the group consisting of natural and synthetic water-swellable clay minerals. This sealant has excellent water-preventing performance, stability in lapse of time and self-sealing properties, is excellent in heat stability, and has clayey plasticity to ensure high work-efficiency, and also has water-swelling properties suitable for use in water-preventing work and so on.
