    摘要: The invention relates to an optionally foamed sealing composition for preformed seals which can swell when treated with water. The invention also relates to a method for the production thereof out of natural rubber and/or elastomers with a matrix comprised of natural rubber/elastomer components and particle-shaped water absorbing material stored therein. The water absorbing material is a combination of (A) polysaccharide(s) selected from cellulose, starch, starch derivatives removed from grafted starch, amylose, amylopectin, dextran, pectin, inulin, chitin, xanthan, alginic acid, alginates, carrageenan, pustulan, callose, laminarin, guluronic acid, pullulan, lichenin or mixtures of the same with (B) a highly water absorbent synthetic polymer selected from polymers based on (meth)acrylate, poly(meth)acrylic acid and the salts thereof, polyacrylamide, polyalcohols or copolymers of said synthetic polymers. The invention also relates to additional cross-linking and processing auxiliary agents and to property improving agents. It is possible to securely seal superstructures, substructures, tunnels and canals with the assistance of the inventive sealing compositions.

    摘要: This invention relates to sealing compositions and, more particularly, sealing compositions for use in conjunction with tail seals of tunnelling machines. In particular a sealing composition according to the invention comprises, by mass, from 10 to 55% of a petroleum-derived wax, or wax-consistency hydrogenated vegetable oil or fat, or a polyisoobutane of oil, grease or wax consistency, or any combination of the above, from 0.5 to 15% of a lipophilic emulsifier, and water in sufficient concentration (at least 20% preferably 20-75%) to inhibit combustion of the composition.

    摘要: This invention relates to a jointing compound of an acrylate/acrylonitrile copolymer containing 2 to 8 carbon atoms in the alcohol component as binder and fatty compounds as plasticizer and also fillers and auxiliaries. Epoxystearic acid methyl ester in particular may be used as the fatty compound while a butyl acrylate/acrylonitrile copolymer in particular may be used as the acrylate/acrylonitrile copolymer. The combination of the two substances results in jointing compounds characterized by a dramatic improvement in elasticity (resilience). Accordingly, they are particularly suitable for substrates with different coefficients of thermal expansion.
