Preparation method of 3D printing rapid prototyping inorganic powder material
The invention discloses a preparation method of a 3D printing rapid prototyping inorganic powder material. The method comprises the steps of: (1) preparing materials; (2) putting the main materials inparts by weight into a vibration mixer, and fully mixing for 1-1.5 hours; (3) briquetting the mixed raw materials, and sintering the mixed raw materials at a high temperature of 800-900 DEG C for 2-3hours; (4) cooling the sintered raw materials to a normal temperature state, grinding the sintered raw materials into powder by using a grinding machine, and grinding the powder, water and a hot meltadhesive into slurry in a ball mill; and (5) mixing and drying the slurry and a fiber base material, adding an auxiliary agent, performing kneading at a high speed, carrying out melt blending extrusion at a high temperature by using a screw extruder, and granulating to obtain particles. The obtained inorganic powder material is high in mechanical property, good in thermal stability, good in flameretardance and high in weather resistance, can be more widely applied to the field of rapid forming, and is high in product toughness, high in thermal deformation temperature and excellent in comprehensive performance when used in the field of forming.
本发明公开了一种三D打印快速成型无机粉末材料的制备方法，包括以下步骤；步骤(1)、备料；步骤(2)、将上述重量份的主料置于振动混料机中充分混合1‑1.5h；步骤(3)、将混合好的原料压块在800‑900的温度下高温烧结2‑3h；步骤(4)、将烧结好的原料冷却到常温状态，并利用研磨机进行研磨成粉体，将粉体与水和热熔胶置于球磨机内研磨成浆液；步骤(5)、将浆液与纤维基料混合干燥，然后加入助剂进行高速的捏合，并利用螺旋挤出机在高温下熔融共混挤出、造粒得到颗粒。本发明得到的无机粉末材料力学性能强、热稳定性好、阻燃性好、耐候性强，在快速成型领域中能够得到更加广泛的应用，用于成型领域的产品韧性强，热变形温度高，综合性能优越。
