The invention discloses a cement-based composite slurry for 3D printing. The cement-based composite slurry comprises 30-50 parts of Portland cement, 8-12 parts of ceramic foundry sand, 6-8 parts of modified zirconia ceramic whisker, 4-6 parts of modified boron carbide ceramic whisker, 10-20 parts of polyurethane modified epoxy resin emulsion, 0.2-0.4 part of sodium lignin sulfonate, 1-2 parts of polysilazane, and 20-40 parts of deionized water. The invention also discloses a preparation method of the cement-based composite slurry for 3D printing. The preparation method comprises the following steps: (1) adding polyurethane modified epoxy resin emulsion and polysilazane into water, and stirring and mixing to obtain a mixed emulsion; and (2) adding Portland cement, ceramic foundry sand, modified zirconia ceramic whiskers, modified boron carbide ceramic whiskers and sodium lignin sulfonate into the mixed emulsion, and stirring and mixing to obtain the cement-based composite slurry for 3D printing.
本发明公开了一种3D打印用水泥基复合浆料，包括30‑50份硅酸盐水泥、8‑12份宝珠砂、6‑8份改性氧化锆陶瓷晶须、4‑6份改性碳化硼陶瓷晶须、10‑20份聚氨酯改性环氧树脂乳液、0.2‑0.4份木质素磺酸钠、1‑2份聚硅氮烷、20‑40份去离子水，本发明还公开了一种3D打印用水泥基复合浆料的制备方法，包括以下步骤：（1）将聚氨酯改性环氧树脂乳液、聚硅氮烷加入水中搅拌混合，得混合乳液；（2）将硅酸盐水泥、宝珠砂、改性氧化锆陶瓷晶须、改性碳化硼陶瓷晶须、木质素磺酸钠加入混合乳液中，搅拌混合，得3D打印用水泥基复合浆料。
