Abstract
A base material for a disk roll containing a layered silicate, in which the layered silicate is constituted to contain two or more kinds of minerals having an interlayer distance exceeding 10 angstroms. A base material for a disk roll is excellent in the compressive strength and wear resistance thereby.
Claims11
A base material for a disk roll comprising:
- a layered silicate,
- wherein the layered silicate contains two or more kinds of minerals having an interlayer distance exceeding 10 angstroms,
- the two or more kinds of minerals having an interlayer distance exceeding 10 angstroms include at least a vermiculite and a smectite, and
- a content ratio relative to a mass of the base material for a disk roll is 10 to 40 mass % for the vermiculite, and is 2 to 20 mass % for the smectite.

A production method of a base material for a disk roll comprising:
- preparing a slurry containing a layered silicate;
- and
- producing a base material for a disk roll by molding the slurry,
- wherein as the slurry, a slurry containing two or more kinds of layered silicates having an interlayer distance exceeding 10 angstroms is prepared, and this is molded to produce a base material for a disk roll, and
- thereby producing the base material for a disk roll includes a vermiculite and a smectite as the mineral having an interlayer distance exceeding 10 angstroms,
- wherein a content ratio relative to a mass of the base material for a disk roll is 10 to 40 mass % for the vermiculite, and is 2 to 20 mass % for the smectite.
