Binder for ceramic powder 3DP forming and preparation method thereof
The invention discloses a binder for ceramic powder 3DP forming, and the binder is characterized in that the binder comprises the following components in parts by mass: 90-100 parts of a base material, 15-20 parts of water-based styrene acrylic copolymer resin and 0.1-1 part of a surfactant, wherein the viscosity of the binder is 2-12 mPa.S, and the surface tension of the binder is 30-38mN/m. According to the technical scheme, the water-soluble styrene-acrylic acid copolymer resin is used as a cross-linked polymer, so the problems of low green body strength, difficulty in powder cleaning treatment, low density of a sintered ceramic product and high dielectric loss caused by poor wettability of the surfaces of a binder and ceramic powder are effectively solved. And the adhesive is simple inpreparation method and convenient to use, and the raw materials are easy to obtain.
本申请公开了一种用于陶瓷粉末3DP成型的粘结剂，其特征在于，包括下述质量份的组分：基料90～100份、水性苯乙烯‑丙烯酸共聚树脂15～20份、表面活性剂0.1～1份，所述粘结剂的粘度2‑12mPa.s，表面张力30‑38mN/m。本技术方案通过将水溶性苯乙烯‑丙烯酸共聚树脂作为交联聚合物，有效解决了粘结剂与陶瓷粉末表面润湿性不好，导致坯体强度低，清粉处理困难，烧成的陶瓷制件致密度低，介电损耗大的问题。并且该粘结剂制备方法简单，使用方便，原料容易获得。
