Colored decorative mortar for 3D printing
The invention discloses colored decorative mortar for 3D printing. The colored decorative mortar comprises 80-100 parts of white high-alumina cement, 100-150 parts of fine sand, 50 to 100 parts of coarse sand, 30-50 parts of high-strength gypsum powder, 10-20 parts of polyacrylate emulsion, 10-20 parts of inorganic pigment, 5-10 parts of a polycarboxylate water reducing agent, 5-10 parts of wood fibers, 5-10 parts of a volume stabilizer, 10-20 parts of a thixotropic agent special for 3D printing, 5-10 parts of an early strength agent, 5-10 parts of a retarder and 50-70 parts of water. According to the invention, the white high-alumina cement is adopted, the whiteness is greater than 88, and the 3-day compressive strength is not lower than 50.0 MPa; the high whiteness is beneficial to the freshness of the inorganic pigment color, and the white high-alumina cement has higher setting speed and higher early strength than ordinary Portland cement. The high-strength gypsum powder is also added to promote quicker setting of the mortar and achieve higher early strength, and in addition, the special thixotropic agent for 3D printing, the early strength agent, the volume stabilizer and otherassistants are also added, so that the mortar raw material is suitable for 3D printing and has high early strength and stable later strength development.
本发明公开了一种3D打印的彩色装饰砂浆，包括：白色高铝水泥80‑100份、细砂100‑150份、粗砂50‑100份、高强石膏粉30‑50份、聚丙烯酸酯乳液10‑20份、无机颜料10‑20份、聚羧酸减水剂5‑10份、木质纤维5‑10份、体积稳定剂5‑10份、3D打印专用触变剂10‑20份、早强剂5‑10份、缓凝剂5‑10份、水50‑70份。本发明采用白色高铝水泥，白度大于88，3天抗压强度不低于50.0MPa；白度高利于无机颜料颜色的鲜度体现，而白色高铝水泥比普通硅酸盐水泥的凝结速度更快和早期强度更高。本发明还添加了高强石膏粉，促进砂浆更快凝结和具备更高的早期强度，另外还添加了3D打印专用触变剂、早强剂、体积稳定剂等助剂，使砂浆原料适用于3D打印，早期强度高，后期强度发展稳定。
