Light-cured 3D printing ceramic slurry and preparation method thereof
The invention discloses light-cured 3D printing ceramic slurry and a preparation method thereof. The light-cured 3D printing ceramic slurry is prepared from silane modified ceramic powder, photosensitive resin premixed liquid, a dispersing agent and other auxiliaries; the volume ratio of the silane modified ceramic powder to the photosensitive resin premixed liquid is 40/60-60/40; the content of the dispersing agent accounts for 0.3%-5% of the mass of the silane modified ceramic powder; the content of the other auxiliaries accounts for 0.5%-1.5% of the mass of the silane modified ceramic powder; the photosensitive resin premix liquid comprises a water-based monomer, water-based urethane acrylate and a photoinitiator; AND the mass ratio of the water-based monomer to the water-based urethaneacrylate is 7/3-9/1. The light-cured 3D printing ceramic slurry is a washable material and is good in environmental protection property; the light-cured 3D printing ceramic slurry is a solvent-free printing material and is good in printing performance and high in precision; the solid content of the slurry can reach 52 vol% or above; obvious sedimentation is avoided after the slurry stands for atleast one month or above; and a degreased and sintered product is high in density and high in mechanical property.
本申请公开了一种光固化3D打印陶瓷浆料及其制备方法，其中，光固化3D打印陶瓷浆料，包括硅烷改性陶瓷粉末、光敏树脂预混液、分散剂和其他助剂；所述硅烷改性陶瓷粉末与所述光敏树脂预混液体积比为40/60～60/40；所述分散剂含量占所述硅烷改性陶瓷粉末质量0.3％～5％，所述其他助剂含量占所述硅烷改性陶瓷粉末质量0.5％～1.5％；且所述光敏树脂预混液包括水性单体、水性聚氨酯丙烯酸酯和光引发剂；水性单体与所述水性聚氨酯丙烯酸酯混合的质量比为7/3～9/1。本申请的光固化3D打印陶瓷浆料是一种可水洗材料，环保性好，且为无溶剂型打印材料，打印性能好，精度高；固含量可达52vol％以上，静置至少1个月以上无明显沉降，脱脂烧结后产品致密度高、力学性能高。
