3D printing thermal insulation mortar and preparation method and application thereof
The invention relates to the technical field of thermal insulation mortar, in particular to 3D printing thermal insulation mortar and a preparation method and application thereof. The thermal insulation mortar comprises the following components in parts by weight: 60-100 parts of white Portland cement, 0.5-1.5 parts of water-based tackifying resin, 1-3 parts of nano montmorillonite, 5-10 parts ofpolyphenyl granules, 5-10 parts of quartz sand, 1-5 parts of glass beads, 0.3-1 part of a thickening agent, 0.3-0.7 part of a water reducing agent and 50-70 parts of water. According to the invention,white Portland cement is used as a main cementing material, and the adhesive property and rheological property of the thermal insulation mortar are synergistically regulated and controlled through anadditive to meet the extrudability requirement necessary for 3D printing. Meanwhile, the structural stability of the 3D printing thermal insulation mortar is improved by doping the nano-clay materialso that the rheological property of the 3D printing thermal insulation mortar is controllable, coloring is easy, and the mechanical property of the 3D printing thermal insulation mortar can be improved.
本发明涉及保温砂浆技术领域，尤其涉及一种3D打印保温砂浆及其制备方法与应用。所述保温砂浆包括如下重量份的组分：白色硅酸盐水泥60～100份、水性增粘树脂0.5～1.5份、纳米蒙脱土1～3份、聚苯颗粒5～10份、石英砂5～10份、玻化微珠1～5份、增稠剂0.3～1份、减水剂0.3～0.7份、水50～70份。本发明采用白色硅酸盐水泥作为主要胶凝材料并通过外加剂来协同调控保温砂浆的粘接性能和流变性能来满足3D打印所必需的挤出性要求。同时通过掺入纳米黏土材料改善3D打印保温砂浆的结构稳定性，不仅可以使3D打印保温砂浆的流变性能可控、易着色，还能改善其力学性能。
