Embodiment 1
[0031] This embodiment provides a preparation method of silica aerogel ink for 3D direct writing printing (the operation process is as follows: figure 1 shown), which includes the following steps:
[0032] The first step, prepare defoaming polyvinyl alcohol solution, the method is:
[0033] In an airtight container, the polyvinyl alcohol solid particles are slowly stirred and dissolved in an ethanol-water solvent system under heating at 80° C. to obtain a defoaming polyvinyl alcohol solution with a solid content of 8 wt %. In the preparation process, the mass ratio of water and ethanol is controlled at 9:1;
[0034] The second step is to prepare a glue solution that can be used for gel curing by:
[0035]A defoaming polyvinyl alcohol solution, glycerol and water were added to the aqueous silica sol with a solid content of 40%, and the solution was slowly stirred for 15 minutes at room temperature to obtain a homogeneous, stable, gel-solidifying solution. In this process, th...
