Embodiment Construction

[0028] The following specific examples will be used to further describe the present invention in detail, but should not be construed as any limitation to the protection content of the present invention.

[0029] 1. Preparation of a composition with open microporous ceramics for 3D printing

[0030] Preparation of ceramic slurry A for 3D printing: Ceramic powder, water, dispersant, binder, unsaturated ethylenic monomer, polyene crosslinking agent, and ammonium persulfate are respectively 20-60%, 20- 60%, 0.2%-4%, 0.5%-10%, 3%-20%, 0.1-4% and 0.1-2% are prepared as ceramic slurry A for 3D printing.

[0031] According to the change of the proportion of different raw materials in the ceramic slurry A for 3D printing of the present invention, the properties of the ceramic slurry A for 3D printing will have certain changes, and the specific changes are mainly from the fluidity of the printable ceramic slurry A and the printability of the ceramic slurry A. The formability of the cer...

Abstract

The invention relates to a composition with open cell ceramics for 3D printing preparation. The composition comprises slurry A for 3D printing and a curing agent B, wherein the slurry A for 3D printing comprises ceramic powder, water, a dispersing agent, an adhesive, an unsaturated alkene monomer, a polyene cross-linking agent and ammonium persulfate; the curing agent B is an aqueous solution containing tetramethylethylenediamine. The using method of the composition with open cell ceramics for 3D printing preparation comprises the following steps: I) injecting the slurry A for 3D printing into a 3D printer by using an ink-jet printing method, and printing into a ceramic preform YT; II) curing the ceramic preform YT in the curing agent B, and drying in the shade at a room temperature so as to obtain a cured ceramic body GT; III) sintering the obtained ceramic body GT at a high temperature, removing the organic matter, thereby obtaining the rich open cell ceramics with the pore size of less than 10 microns.

Description

technical field [0001] The present invention relates to a material for 3D printing. More specifically, the present invention relates to a composition for 3D printing to prepare open microporous ceramics and a method for using the same, belonging to the field of 3D printing materials. Background technique [0002] The use of 3D printing technology to prepare ceramics with specific structures is becoming an important direction in the field of 3D printing technology. Among them, combining different 3D printing technologies to develop corresponding printable ceramic materials has become a key research and development direction of this technology. At present, different ceramic materials that can be used for 3D printing have been developed one after another. For example, in order to match the selected area laser sintering (SLS) printing technology, a mixture of corresponding ceramic powder and a certain binder powder has been developed; Printing materials have been developed; fo...
