| titleOfInvention | Coating composition for casting 3D sand mold printing |
| abstract | The invention relates to the field of casting auxiliary materials for 3D sand mold printing, and relates to a coating composition for casting 3D sand mold printing, which comprises the following components in parts by weight: 100 parts of refractory filler, 20-60 parts of water, 0.1-15 parts of solubilizer, 0.01-10 parts of air permeability improving material, 0.01-5 parts of high-temperature fading agent, 0.1-5 parts of anti-settling agent, 0.01-4 parts of carbon residue generating agent and 0.01-1 part of penetrating agent. The coating composition disclosed by the invention is low in viscosity, and adjustable in coating thickness and penetration depth; meanwhile, the high-temperature air permeability is good, and the defects of possible subcutaneous air holes, insufficient pouring and the like are eliminated; the effective working time of the coating is effectively prolonged, and the tendency of metal penetration is reduced to the maximum extent; the method can be applied to all 3D printing sand molds including machine tool type castings, machine frame type castings and cylinder head type castings, and particularly relates to a 3D printing casting process aiming at complex structure, more heat and high surface quality requirements. |
