NEAR-INFRARED PHOTOTHERMAL COUPLING CURING NON-OXIDE CERAMIC SLURRY AND ITS PREPARATION METHOD AND APPLICATION
The invention presents a near-infrared photothermal coupling curing non-oxide ceramic slurry, along with its preparation method and application. The ceramic slurry consists of various raw materials, with weight fractions as follows: non-oxide ceramic powder (40˜90 parts), photosensitive resin (0.5˜20 parts), photosensitive monomer (1˜40 parts), photoinitiator (0.25˜4 parts), thermal initiator (0.25˜4 parts), additive (0.75˜5 parts), and up-conversion luminescent material (0.5˜4 parts). The non-oxide ceramic powders can include Si3N4, TiN, BN, AlN, SiC, WC, TiC, ZrC, TiB2, and ZrB2. By combining the photochemical and photothermal dual curing system using near-infrared up-conversion, this invention addresses the issue of insufficient curing encountered in single photocuring or thermal curing processes. Moreover, by incorporating near-infrared light source-driven additive manufacturing, it enables rapid prototyping of high-solid-content non-oxide ceramic slurry, ultimately allowing for the fabrication of high-fidelity non-oxide ceramic structures.
