Bonding type 3D printing similar material for complex geological model
The invention relates to a bonding type 3D printing similar material for a complex geologic model, the bonding type 3D printing similar material comprises a powder material and ink, the powder material comprises, by weight, 10-40 parts of dead burned MgO, 5-30 parts of phosphate, 30-100 parts of barite powder, 8-25 parts of semi-hydrated gypsum, and 50-100 parts of a precision improvement component; the ink is prepared from 3%-10% of a viscosity modifier, 0.5%-2.5% of a solubilizing stabilizer, 0.1%-0.8% of a surface tension modifier, 0.01%-0.1% of a defoaming agent, 3%-6% of a humectant and 80%-97% of deionized water. The viscosity modifier is at least one of PVA (Polyvinyl Alcohol), polyvinylpyrrolidone or xanthan gum; the weight ratio of the ink to the powder material is 0.2-0.4; the precision improving component comprises PVA powder and cement clinker powder, and the mass ratio of the PVA powder to the cement clinker powder is (1: 5)-(1: 8); the hydrotropy stabilizer is at least one of 2-pyrrolidone and sodium pyrrolidone carboxylate. On the premise of realizing 3D printing, mechanical indexes such as material strength, elastic modulus, density and brittleness can meet similarity requirements.
