preparation example Construction

[0037] Correspondingly, an embodiment of the present invention provides a method for preparing an adhesive for photocuring ceramic 3D printing, comprising the following steps:

[0038] S01. Weigh each component according to the above-mentioned formula of the adhesive used for photocuring ceramic 3D printing;

[0039] S02. Disperse and stir each component while feeding at a constant temperature of 40-50°C, and the stirring speed is 500-600 rpm to obtain a mixed material;

[0040] S03. Cool the mixed material to normal temperature, and perform centrifugal dispersion treatment under vacuum conditions;

[0041] S04. Filtrating the mixed material after centrifugal dispersion to obtain an adhesive slurry.

[0042] Specifically, in the above step S01, the formulation components of the adhesive used for photocuring ceramic 3D printing and its preferred conditions are as described above, and will not be repeated here in order to save space.

[0043] In the above step S02, since the c...

Abstract

The invention provides an adhesive for 3D printing of photocurable ceramic and a preparation method and application of the adhesive. The adhesive for 3D printing of photocurable ceramic is prepared from, by weight, 60-85% of ceramic powder, 5-14% of photocurable resin, 5-18% of acrylate monomer, 1-5% of UV photoinitiator and 1-3% of other auxiliaries.

Description

technical field [0001] The invention belongs to the technical field of adhesives for 3D printing, and in particular relates to an adhesive for 3D printing of light-cured ceramics, its preparation method and application. Background technique [0002] The traditional ceramic processing technology is to make ceramic materials into green bodies of specified size and shape through grouting, powder pressing, etc. under the premise of mold making, and then obtain them by firing. Due to the manufacturing defects of the mold, such as high mold opening cost, low ceramic mold yield and traces on the mold surface, traditional ceramic processing technology cannot complete complex-shaped and high-precision products. Therefore, the traditional ceramic processing technology has become a bottleneck restricting the further development of ceramic products. [0003] 3D printing manufacturing technology refers to the technology of manufacturing solid parts based on the principle of layer-by-lay...
