Ultralow-viscosity light-cured ceramic resin slurry
The invention relates to the technical field of light-cured ceramic resins, particularly to ultralow-viscosity light-cured ceramic resin slurry, which comprises the following raw materials in parts byweight: 60-75 parts of coarse ceramic powder, 25-40 parts of fine ceramic powder, 20-30 parts of light-cured resin prepolymer, 25-40 parts of a reactive diluent, 0.15-0.25 part of a photoinitiator, 0.018-0.05 part of a polymerization inhibitor, 2.5-5.5 parts of a dispersing agent and 0-4.2 parts of a defoaming agent, wherein the coarse ceramic powder and the fine ceramic powder comprise the following components in parts by weight: 98 to 99.5 parts of Al2O3, 0.2 to 0.5 part of Na2O, 0.1 to 0.2 part of SiO2 and 0.02 to 0.05 part of Fe2O3. According to the invention, the coarse ceramic powder and the fine ceramic powder are proportionally matched, so that the viscosity of the slurry is reduced under the condition of ensuring the solid content of the slurry, the processability of the slurry is optimized, and the strength and reliability of a ceramic product are also ensured.
本发明涉及光固化陶瓷树脂技术领域，尤其涉及一种超低粘度光固化陶瓷树脂浆料，包括以下重量份的原料：粗陶瓷粉体60～75份、细陶瓷粉体25～40份、光固化树脂预聚物20～30份、活性稀释剂25～40份、光引发剂0.15～0.25份、阻聚剂0.018～0.05份、分散剂2.5～5.5份、消泡剂0～4.2份；粗陶瓷粉体和细陶瓷粉体的组份以重量份计为：Al2O3 98～99.5份、Na2O 0.2～0.5份、SiO2 0.1～0.2份、Fe2O3 0.02～0.05份。将粗陶瓷粉体和细陶瓷粉体按比例配合，在保证浆料固含量的情况下降低了浆料的粘度，优化了浆料的加工性能，也保证了陶瓷产品的强度和可靠性。
