Titanium dioxide photosensitive resin ceramic slurry as well as preparation method and application thereof
The invention belongs to the technical field of non-metal additive manufacturing, and particularly relates to gradient particle size titanium dioxide photosensitive resin ceramic slurry and a preparation method and application thereof. The titanium dioxide photosensitive resin ceramic slurry is prepared from the following components in parts by volume: 25-55 parts of oligomer, 10-25 parts of monomer, 3-8 parts of reactive diluent, 3-5 parts of dispersing agent, 9-18 parts of photoinitiator, 1-3 parts of assistant and 1-40 parts of titanium dioxide ceramic powder. According to the invention, amixed photoinitiator and a mixed light source are adopted; compared with the traditional photocuring equipment which uses a single ultraviolet light source and ceramic slurry which uses a single photoinitiator, the light absorption curing reaction of the ceramic photosensitive resin slurry is enhanced, so that the reflection of titanium dioxide ceramic to light is counteracted; therefore, it is ensured that the slurry curing depth reaches a certain scale in unit time, defects are few, and the forming effect is good.
本发明属于非金属增材制造技术领域，具体涉及一种梯度粒径二氧化钛光敏树脂陶瓷浆料及其制备方法和应用。本发明一种梯度粒径二氧化钛光敏树脂陶瓷浆料，按照体积份数，包括以下组分：低聚物25‑55份、单体10‑25份、活性稀释剂3‑8份、分散剂3‑5份、光引发剂9‑18份、助剂1‑3份、二氧化钛陶瓷粉末1‑40份。本发明采用混合类光引发剂和混合光源，相比以往传统光固化设备为单一紫外光源，陶瓷浆料使用单一光引发剂，本发明增强陶瓷光敏树脂浆料对于光的吸收固化反应，以此抵消二氧化钛陶瓷对于光的反射，确保在单位时间内浆料固化深度达到一定尺度，缺陷少，成型效果好。
