Light-cured silicon nitride ceramic and preparation method thereof
The invention discloses light-cured silicon nitride ceramic and a preparation method thereof. The silicon nitride ceramic is prepared from the following raw materials in parts by weight: 35-45 parts of silicon nitride, 3-4 parts of nano titanium dioxide, 0.4-1.2 parts of a defoaming agent, 2-4 parts of iron-silicon-aluminum, 0.6-0.8 part of a dispersing agent, 0.7-0.9 part of a rheological modifier, 1.4-1.8 parts of glass fibers, 1.6-2 parts of polyether ketone ketone ketone and 30-36 parts of liquid photosensitive resin. Silicon nitride is adopted as a main material and matched with liquid photosensitive resin, under ultraviolet irradiation, a polymer is converted into a hard substance from colloidal resin, a dispersing agent and a defoaming agent are added, the formed silicon nitride ceramic is smooth in surface, uniform in material dispersion and high in strength, a rheology modifier is added, the viscosity rheology characteristic of the silicon nitride ceramic is improved, polyether ketone ketone and glass fibers are subjected to a composite reaction in advance, a composite material capable of enhancing the strength of the silicon nitride ceramic is generated, and after nitrogen calcination, drying, thermal degreasing and sintering, the light-cured silicon nitride ceramic with high strength and low cost is obtained.
