Abstract

The invention discloses a binder for a 3D printed ceramic material and an application of the binder. The binder can promote a curing agent, sol ions and a ceramic surface to form stable chemical bonds such as Si-O, Si-F, Al-O and the like under the conditions of ultraviolet irradiation, normal temperature and normal pressure, the binder and ceramic particles are connected into a whole, and a ceramic product is directly obtained. Popularization and application of the 3D printed ceramic material in life are greatly promoted, and the binder has wide market prospect.

Description

technical field [0001] The invention relates to a binder for 3D printing materials and its application, in particular to a binder for 3D printing ceramic materials and its application. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, is an emerging technology in the field of rapid prototyping. It is based on digital model files and uses bondable materials such as powdered metal or plastic to print layer by layer. Techniques for constructing objects. With the development and application of 3D printing technology, materials have become one of the key factors limiting the future direction of 3D printing technology. To a certain extent, the development of materials determines whether 3D printing can be more widely used. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials, and ceramic materials. The field of printing has been applied. [0003] The d...
