Abstract

A shaping slurry that forms a shaped product with a granule includes: a water-based solvent; a hydrophobic granule that forms the shaped product; and an amphiphatic solid polymer that forms the shaped product, and is dissolved in the water-based solvent.

Claims

1. A shaping slurry that forms a shaped product with a granule,

the shaping slurry comprising:

a water-based solvent;

a hydrophobic granule that forms the shaped product; and

an amphiphatic solid polymer that forms the shaped product, and is dissolved in the water-based solvent.

2. The shaping slurry according to claim 1,

wherein the granule is a resin granule,

wherein the water-based solvent contains a nonorganic main solvent component, and

wherein the amphiphatic solid polymer has a hydrocarbon chain backbone, and a side-chain hydrophilic functional group.

3. The shaping slurry according to claim 1, wherein the amphiphatic solid polymer is polyvinyl alcohol.

4. The shaping slurry according to claim 3,

wherein the water-based solvent is water, and

wherein the polyvinyl alcohol has a polymerization degree of from 300 to 1,000, inclusive.

5. The shaping slurry according to claim 3,

wherein the water-based solvent is water, and

wherein the polyvinyl alcohol has a saponification degree of from 85 to 90, inclusive.

6. The shaping slurry according to claim 1, further comprising a fiber material.
