3D printing gypsum powder and preparation method thereof
The invention discloses a 3D printing gypsum powder and a preparation method thereof. The 3D printing gypsum powder is prepared from, by mass, 80-90 parts of alpha gypsum powder, 5-10 parts of talcum powder, 1-5 parts of white Portland cement, 1-5 parts of modified toughening fiber, 0.1-0.5 part of rubber powder and 0.1-0.3 part of a thickening time control agent. The preparation method comprises the following steps: firstly, mixing the talcum powder, the white Portland cement, the modified toughening fiber, the rubber powder and the thickening time control agent in a V-shaped mixer for 20-40 min, then adding the alpha gypsum powder, feeding into a horizontal mixer, mixing for 0.5-1.5 h, and uniformly mixing the components to obtain the required 3D printing gypsum powder. The method is scientific and reasonable in design, and when the 3D printing gypsum powder is used for 3D printing, due to the fact that the fluidity of the gypsum powder is good, powder laying of a printer is uniform; a printed product is high in strength and easy to form; and the surface of the product is smooth and has no concave-convex pits.
本发明公开了一种3D打印石膏粉及其制备方法，该3D打印石膏粉按质量份计，包括以下组分：α石膏粉80‑90份，滑石粉5‑10份，白色硅酸盐水泥1‑5份，改性增韧纤维1‑5份，胶粉0.1‑0.5份，调凝剂0.1‑0.3份；制备方法为：先将滑石粉、白色硅酸盐水泥、改性增韧纤维、胶粉、调凝剂在V型混合机内混合20‑40min，然后加入α石膏粉一同送入卧式混合机中，混合0.5‑1.5h，使各组分混合均匀，即可得到所需3D打印石膏粉。本发明方法设计科学合理，利用本发明提供的3D打印石膏粉进行3D打印时，由于石膏粉的流动性较好，打印机铺粉比较均匀；打印的制品强度高，易成型；制品表面光滑，无凹凸坑点。
