Colored 3D printing mortar and preparation method thereof
The invention relates to the field of 3D printing mortar, and particularly discloses colored 3D printing mortar and a preparation method thereof, the colored 3D printing mortar comprises the following components: white Portland cement, limestone powder, metakaolin, an organic pigment, an internal curing agent, quartz sand, fibers, a water reducing agent, an alkali-free accelerator, an early strength agent, a defoaming agent, a polymer emulsion and water; the preparation method comprises the following steps: S1, uniformly mixing quartz sand and fibers to obtain M1; S2, uniformly mixing cement, limestone powder, metakaolin, an internal curing agent and M1 to obtain M2; S3, uniformly mixing a water reducing agent, an early strength agent, a defoaming agent and water to obtain M3; S4, uniformly stirring the polymer emulsion and the organic pigment to obtain M4; and S5, uniformly mixing and stirring M3 and M2, adding M4 while stirring, finally adding an accelerator, and uniformly mixing. The prepared mortar is proper in flowability, good in thixotropy and excellent in extrusion performance; and after printing is completed, early strength and later strength are well developed, and the product is bright in color and good in weather resistance.
本申请涉及3D打印砂浆的领域，具体公开了一种彩色3D打印砂浆及其制备方法，包括以下组分：白色硅酸盐水泥、石灰石粉、偏高岭土、有机颜料、内养护剂、石英砂、纤维、减水剂、无碱速凝剂、早强剂、消泡剂、聚合物乳液、水；其制备方法包括以下步骤：S1，将石英砂和纤维混合均匀得到M1；S2，将水泥、石灰石粉、偏高岭土、内养护剂与M1混合均匀得到M2；S3，将减水剂、早强剂、消泡剂和水混合均匀得到M3；S4，将聚合物乳液和有机颜料搅拌均匀得到M4；S5，将M3与M2混合搅拌均匀，边搅拌边加入M4，最后加入速凝剂混合均匀。其制得的砂浆流动性合适，触变性好，挤出性能佳；打印完成后早期强度和后期强度发展良好，产品颜色鲜艳，耐候性佳。
