Mixed soil material for 3D printing earthen archaeological site and preparation method
The invention discloses a mixed soil material for 3D printing of earthen ruins and a preparation method. The mixed soil material is prepared from the following components in parts by weight: 5500 to 7500 parts of ruin soil, 0 to 1800 parts of artificial gravel powder, 1000 to 1500 parts of sulphoaluminate cement, 100 to 200 parts of lime, 100 to 150 parts of starch ether, 80 to 120 parts of plant fiber, 10 to 30 parts of mineral pigment, 5 to 12 parts of silane coupling agent, 5 to 12 parts of polyacrylamide, 5 to 10 parts of naphthalene sulfonate formaldehyde condensate and 900 to 1300 parts of water. The preparation method comprises the following steps: carrying out experimental analysis on the ruin soil, and determining the particle size group and the mixing amount of the artificial gravel powder; weighing the ruin soil, the artificial gravel powder, the sulphoaluminate cement, the lime, the starch ether, the plant fiber and the mineral pigment, and uniformly stirring to obtain a first mixture; the preparation method comprises the following steps: weighing a silane coupling agent, polyacrylamide, a naphthalene sulfonate formaldehyde condensate and water, and uniformly stirring to obtain a first solution; and uniformly stirring the first mixture and the first solution. The mixed soil material disclosed by the invention can meet the requirement of 3D printing, and the color, strength and durability of the formed mixed soil material meet the cultural insurance requirement of repairing the old as the old.
本发明公开了一种用于3D打印土遗址的混合土料及制备方法，该混合土料组分及重量份数为：遗址土5500‑7500份、人工砂石粉0‑1800份、硫铝酸盐水泥1000‑1500份、石灰100‑200份、淀粉醚100‑150份、植物纤维80‑120份、矿物颜料10‑30份、硅烷偶联剂5‑12份、聚丙烯酰胺5‑12份、萘磺酸盐甲醛缩合物5‑10份、水900‑1300份。该制备方法为：对遗址土进行试验分析，确定人工砂石粉的粒径组、掺量；称取遗址土、人工砂石粉、硫铝酸盐水泥、石灰、淀粉醚、植物纤维、矿物颜料，搅拌均匀得到第一混合物；称取硅烷偶联剂、聚丙烯酰胺、萘磺酸盐甲醛缩合物、水，搅拌均匀得到第一溶液；将第一混合物和第一溶液搅拌均匀即可。本发明混合土料能达到3D打印的要求，成型后颜色、强度、耐久性能达到修旧如旧的文保要求。
