Ceramic core slurry as well as preparation method and application thereof
The invention belongs to the technical field of 3D printing materials, and particularly relates to ceramic core slurry as well as a preparation method and application thereof. According to the ceramic core slurry provided by the invention, the acrylate oligomer is used as a main body of the ceramic core slurry, and once the acrylate oligomer is subjected to initiated polymerization, the molecular weight is rapidly increased, and the acrylate oligomer is rapidly cured to form a solid; the acrylate monomer plays a role of a reactive diluent, is subjected to a polymerization reaction under the action of illumination, and can also be used for dissolving and diluting the acrylate oligomer, reducing the viscosity of the ceramic core slurry and improving the fluidity of the ceramic core slurry; the ceramic core slurry provided by the invention is high in solid content and excellent in fluidity, the ceramic core slurry provided by the invention is used for 3D printing, and an obtained 3D printed ceramic core has the characteristics of high bending strength, excellent high-temperature creep resistance, small shrinkage rate and good surface quality.
本发明属于3D打印材料技术领域，具体涉及一种陶瓷型芯浆料及其制备方法和应用。本发明提供的陶瓷型芯浆料，以丙烯酸酯低聚物作为陶瓷型芯浆料的主体，丙烯酸酯低聚物一经引发聚合，分子量会快速增大，迅速固化形成固体；丙烯酸酯类单体起到活性稀释剂的作用，在光照作用下发生聚合反应，还可以溶解和稀释丙烯酸酯低聚物，降低陶瓷型芯浆料的粘度，提高陶瓷型芯浆料的流动性；本发明提供的陶瓷型芯浆料固含量高且流动性优良，本发明提供的陶瓷型芯浆料3D打印，得到的3D打印陶瓷型芯具有抗弯曲强度高、抗高温蠕变性优异、收缩率小且表面质量好的特点。
