Method for producing montmorillonite slurry, clay film, and montmorillonite slurry

摘要

PROBLEM TO BE SOLVED: To stably disperse lithium-fixed montmorillonite in which lithium ions are immobilized and cation exchange property and water dispersibility are deteriorated, and the particle size of the dispersed lithium-fixed montmorillonite is sufficiently small, which is industrial. To provide a slurry that does not easily cause safety problems in use. SOLUTION: Lithium-fixed montmorillonite having a cation exchange capacity of 50 meq / 100 g or less is dispersed in a polar medium composed of a mixture of ammonia, water and a lower alcohol, and the lithium-fixed montmorillonite in the dispersed state is dispersed. A montmorillonite slurry having a particle size of 10 μm or less. [Selection diagram] None
