摘要

A method for producing a modified smectite or modified smectite-containing substance, modified smectite or modified smectite-containing substance and use thereof The present invention relates to a method for producing a modified smectite or modified smectite-containing substance capable of forming gels which are no longer thixotropic, have a stable cross-linked structure and adhesive characteristic and are capable of absorbing and releasing water in a reversible manner by treating an unactivated smectite or non-activated smectite-containing substance with a water-soluble activating agent and a water-soluble polymer. water capable of reacting with said smectite, wherein 0 to 6% by weight, calculated on the weight of unactivated smectite, water-soluble activating agent and 0.3 to 6% by weight, calculated on the weight of smectite water-soluble polymer are mixed with the smectite or smectite-containing that: at least a part of the water-soluble activating agent is added before and / or at least simultaneously with the soluble polymer, wherein at least a part of the water-soluble polymer is added as a dry solid, the obtained mixture contains an amount of water in a range of 20 wt% water to 50 wt% water, on the basis of the mixture.
