Low-shrinkage light-cured ceramic slurry and preparation method thereof
The invention discloses low-shrinkage light-cured ceramic slurry and a preparation method thereof, and belongs to the technical field of light-cured printing materials, the low-shrinkage light-cured ceramic slurry is characterized by comprising, by volume, 45%-55% of spiral light-cured resin and 45%-55% of ceramic powder; wherein the spiro-type light-cured resin comprises the following components in percentage by mass: 35-38wt% of cationic photosensitive resin, 10-20wt% of a curing agent, 1-5wt% of a curing agent, 1-5wt% of a 20 to 22 wt% of free radical type photosensitive resin; 15-17 wt% of a cationic photosensitive resin reactive diluent; 20-21 wt% of a free radical type photosensitive resin reactive diluent; 3.5 to 4 wt% of a cationic photoinitiator; and 3-3.5 wt% of a free radical type photoinitiator. The invention provides the ceramic slurry with low molding shrinkage rate.
