Abstract
A montmorillonite slurry, containing a lithium-immobilized montmorillonite having a cation exchange capacity of 50 meq/100 g or less, ammonia, water, and an organic solvent, in which the organic solvent includes at least one kind of organic solvent selected from the group consisting of acetonitrile and methyl ethyl ketone, the proportion occupied by the organic solvent in the total amount of the water and the organic solvent in the slurry is 10% by mass or more and 90% by mass or less, and the content of ammonia in the slurry is 0.1 mmol or more per gram of the lithium-immobilized montmorillonite in the slurry; a method of producing the same; and a clay film.
Claims6
A montmorillonite slurry, comprising:
- a lithium-immobilized montmorillonite having a cation exchange capacity of 50 meg/100 g or less;
- ammonia;
- water;
- and
- an organic solvent,
- wherein the organic solvent is at least one kind of organic solvent selected from the group consisting of acetonitrile and methyl ethyl ketone,
- wherein the proportion occupied by the organic solvent in the total amount of the water and the organic solvent in the slurry is 10% by mass or more and 90% by mass or less;
- and
- wherein the content of ammonia in the slurry is 0.1 mmol or more per gram of the lithium-immobilized montmorillonite in the slurry.
A method of producing a montmorillonite slurry, comprising mixing at least a lithium-immobilized montmorillonite having a cation exchange capacity of 50 meq/100 g or less, ammonia, water, and an organic solvent,
- wherein the organic solvent is at least one kind of organic solvent selected from the group consisting of acetonitrile and methyl ethyl ketone,
- wherein the proportion occupied by the organic solvent in the total amount of the water and the organic solvent in the slurry is 10% by mass or more and 90% by mass or less, and
- wherein the mixing amount of ammonia is 0.1 mmol or more per gram of the lithium-immobilized montmorillonite.
