Ceramic material for photocuring forming as well as emulsion coating preparation method and application of ceramic material
The invention belongs to the related technical field of ceramic materials. The invention discloses a ceramic material for photocuring forming as well as an emulsion coating preparation method and application of the ceramic material. The method comprises the following steps: (1) mixing a photosensitive resin, an emulsifier and deionized water to form a completely dispersed coating precursor emulsion, adding ceramic powder into the coating precursor emulsion, and uniformly dispersing the ceramic powder into the coating precursor emulsion; and (2) adding a photoinitiator into a mixture obtained in the step (1), irradiating with ultraviolet light, carrying out a cross-linking reaction on the photosensitive resin under the irradiation of the ultraviolet light to form a gel on the surface of theceramic powder, and uniformly coating the ceramic powder with the gel to obtain the ceramic material. The method is environmentally friendly, low in cost, high in universality, simple in process, short in preparation period and capable of effectively solving the photocuring manufacturing problem of ceramic parts such as silicon nitride and titanium dioxide.
本发明属于陶瓷材料相关技术领域，其公开了一种用于光固化成形的陶瓷材料及其乳液包覆制备方法、应用，所述方法包括以下步骤：(1)将光敏树脂、乳化剂和去离子水混合成完全分散的包覆前驱物乳浊液，再将陶瓷粉体加入所述包覆前驱物乳浊液中，并使所述陶瓷粉体均匀分散于所述包覆前驱物乳浊液中；(2)将光引发剂加入步骤(1)所得到的混合物中，并采用紫外光进行照射，所述光敏树脂在所述紫外光的照射下发生交联反应，以在所述陶瓷粉体的表面形成凝胶体，所述凝胶体均匀包覆所述陶瓷粉体，进而得到所述陶瓷材料。本发明绿色环保、成本低廉、普适性强、流程简单、制备周期短，可有效解决氮化硅、二氧化钛等陶瓷零件的光固化制造难题。
