Silicon carbide ceramic photocuring slurry and preparation method thereof
The invention provides silicon carbide ceramic photocuring slurry and a preparation method thereof, and the silicon carbide ceramic photocuring slurry comprises silicon carbide powder, a photosensitive resin system, high-light-transmittance organic particles and a dispersant; the ultraviolet transmittance of the high-transmittance organic particles is higher than 60%. The preparation method comprises the following steps: mixing the prepolymer, the resin monomer and the photoinitiator to obtain a photosensitive resin system, adding the silicon carbide powder, the dispersing agent and the high-light-transmittance organic particles into the photosensitive resin system, and homogenizing to obtain the silicon carbide ceramic photocuring slurry. According to the invention, the high-light-transmittance organic particles are added into the silicon carbide slurry to construct the optical channel, and the selected high-light-transmittance organic particles for constructing the optical channel are organic polymer materials with relatively high ultraviolet transmittance, so that ultraviolet light can penetrate into the deep layer of the slurry through the optical channel constructed by the high-light-transmittance organic particles for curing; and the curing depth of the silicon carbide ceramic photocuring slurry is greatly improved.
