Ceramic core slurry for 3D printing as well as preparation method and application of ceramic core slurry
The invention belongs to the technical field of materials for 3D printing, and particularly relates to ceramic core slurry for 3D printing as well as a preparation method and application of the ceramic core slurry. The ceramic core slurry for 3D printing provided by the invention is prepared from the following raw materials: an acrylate monomer, an acrylate oligomer, silicon dioxide powder, zirconium silicate powder, a photoinitiator, a water-based leveling agent and a dispersing agent, wherein the volume ratio of the acrylate monomer to the acrylate oligomer is (2-10): 1; the mass ratio of the silicon dioxide powder to the zirconium silicate powder is 100: (5-20); the ratio of the total volume of the acrylate monomer and the acrylate oligomer to the mass of the silicon dioxide powder is (80-600) mL: (200-1000) g. The ceramic core slurry for 3D printing provided by the invention is high in solid content and excellent in fluidity, and an obtained 3D printing ceramic core is high in bending strength, excellent in high-temperature creep resistance, small in shrinkage rate and good in surface quality.
本发明属于3D打印用材料技术领域，特别涉及一种3D打印用陶瓷型芯浆料及其制备方法和应用。本发明提供的3D打印用陶瓷型芯浆料，由包括以下组分的原料制备得到：丙烯酸酯类单体、丙烯酸酯低聚物、二氧化硅粉、硅酸锆粉、光引发剂、水性流平剂和分散剂；所述丙烯酸酯类单体和丙烯酸酯低聚物的体积比为(2～10)：1；所述二氧化硅粉和硅酸锆粉的质量比为100：(5～20)；所述丙烯酸酯类单体和丙烯酸酯低聚物的总体积与二氧化硅粉的质量的比为(80～600)mL：(200～1000)g。本发明提供的3D打印用陶瓷型芯浆料固含量高且流动性优良，所得3D打印陶瓷型芯抗弯曲强度高、抗高温蠕变性优异、收缩率小且表面质量好。
