3D printing ultralow-temperature rock-like material and preparation method thereof
The invention relates to the technical field of 3D printing materials, in particular to a 3D printing ultralow-temperature rock-like material and a preparation method thereof.The 3D printing ultralow-temperature rock-like material comprises mixed powder A, elemental powder B and a mixed solution C. The 3D printing ultralow-temperature rock-like material is characterized in that the mixed powder A comprises cement, quartz sand, fly ash, silica fume and gneiss powder; the elementary substance powder B comprises bagasse fibers; the mixed solution C comprises the following components in parts by weight: 30-35 parts of cement, 10-15 parts of an anti-freezing agent, 10-15 parts of a defoaming agent and 10-15 parts of a water reducing agent; 43 to 48 parts of quartz sand; 1.7 to 2.5 parts of fly ash; 2.5 to 4 parts of silica fume; 3 to 5 parts of gneiss stone powder; 10 to 13 parts of water; 1 to 2 parts of bagasse fiber; 0.2 to 0.5 part of an anti-freezing agent; 0.3 to 0.5 part of a defoaming agent; and 0.1 to 0.4 part of a water reducing agent. According to the present invention, the structure compactness is increased, the structure porosity and the water content are reduced, the frost resistance of the material is improved, the mechanical property of the material is improved, and the material can be used for the LNG reservoir surrounding rock mass test under the ultralow temperature simulation environment.
