Abstract

The invention relates to the field of ceramics and processing methods thereof, and in particular, relates to 3D printed volcanic pit-shaped texture ceramic and a processing method thereof. The 3D printed volcanic pit-shaped texture ceramic is characterized in that a blank comprises the following components in parts by weight: 20-25 parts of kaolin, 10-12 parts of aluminum oxide, 5-8 parts of zirconium oxide, 10-12 parts of calcium carbonate, 6-7 parts of a surfactant, 50-60 parts of methyl acrylate light-cured resin, 5-7 parts of a dispersing agent, 10-20 parts of hydroxyapatite powder and 30-40 parts of water. According to the 3D printed volcanic pit-shaped texture ceramic and the processing method thereof provided by the invention, blank photocuring and alkali coagulation curing are carried out at the same time, the blank strength can be effectively enhanced through multiple curing modes, and the forming speed is greatly increased; glaze dipping treatment is carried out after the blank is degreased, the porosity is reduced, and cracking and strength reduction of the blank in the firing process are avoided; external light does not need to be isolated in the printing process, and printing conditions can be observed conveniently.

Description

technical field [0001] The invention relates to the field of ceramics and processing methods thereof, in particular to a 3D printed crater-like texture ceramics and a processing method thereof. Background technique [0002] The traditional porcelain plastic production uses mud to shape, dry, mold, pour, and fire, etc., which requires a lot of time and capital costs, and is not easy to modify. Compared with the traditional production process, the application of 3D technology is more in line with the characteristics of modern people. The product model can be made through 3D modeling or 3D scanning, which can be changed based on actual needs, shorten the sample development time, and combine traditional technology with modern technology. , to promote the development of the industry. For example, the invention patent with application number CN201711107565.X is a method for preparing aluminum-based ceramic slurry and ceramic core for light-curing 3D printing.

Problems solved by technology

For example, the invention patent with application number CN201711107565.X is a method for preparing aluminum-based ceramic slurry and ceramic core for light-curing 3D printing. The slurry is composed of three parts: ceramic formula powder, light-curing resin system, and additives , the aluminum-based ceramic slurry for light-curing 3D printing shown in this application has high solid content and low viscosity, and is suitable for photopolymerization in light-curing 3D printing, which overcomes the current materials used in light-curing 3D printing crater-like texture ceramics. The slurry has problems such as high viscosity, poor fluidity, easy agglomeration and uneven dispersion of ceramic particles in the slurry, and low solid content.

However, the existing 3D printing technology of crater-like texture ceramics has some shortcomings: the porosity of the green body after degreasing increases, resulting in a decrease in the strength of the green body, which is fragile and easy to crack; It is filled with liquid photosensitive resin, which will quickly solidify under the irradiation of ultraviolet laser beams. Therefore, the printing environment needs to be isolated from external light. And the firing temperature is low, which is not suitable for high-temperature glaze firing. In view of this, this case arises
