Problems solved by technology

[0005] Aiming at the problems in the prior art that the printing ink is not resistant to high temperature, thermally deformed and collapsed, the surface quality of the casting is poor, not environmentally friendly, and the cost is high, the present invention proposes an inorganic single-component ink for precision casting and a preparation method thereof. The inorganic ink of the present invention The single-component ink has low cost, environmental protection, and high temperature resistance, and has realized the successful application of high temperature resistant inorganic adhesives in the direction of 3D printing precision casting; at the same time, it has overcome the problems in the prior art that the surface tension of inorganic adhesives does not meet the inkjet requirements. Problems such as dispersion and viscosity cannot be applied to 3D printing

Abstract

The invention relates to inorganic single-component ink for precision casting and a preparation method thereof. The inorganic single-component ink is prepared from an inorganic adhesive, deionized water, a thickening agent, a dispersing agent, a surfactant and a defoaming agent; the preparation method of the inorganic single-component ink comprises the following steps: 1, taking a certain amount of the inorganic adhesive, uniformly stirring, slowly adding a certain amount of deionized water into the stirred inorganic adhesive, and stirring for 5-15min; 2, taking a certain amount of a thickener, slowly adding the thickener into the above obtained stirred solution, stirring for 30-120min, slowly adding a certain amount of the dispersant, stirring until the obtained liquid material is uniformly mixed, slowly adding a certain amount of the surfactant, and stirring for 5-20min; and 3, taking a certain amount of the defoaming agent, slowly adding the defoaming agent into the stirred solution, stirring for 10-30 minutes, taking out the liquid material, and performing standing; and carrying out suction filtration treatment on the liquid material and standing for more than 2 hours. The inorganic single-component ink disclosed by the invention has the characteristics of good dispersity, clarity, transparency, difficulty in film formation, no agglomeration, good ink jet effect and the like.
