Embodiment 1

[0022] Binder preparation: 8 parts by weight of sodium silicate, 3 parts by weight of potassium persulfate, and 5 parts by weight of sodium hydroxide are added to 75 parts by weight of magnesium aluminum hydroxide sol, and prepared by ultrasonic vibration dispersion and dissolution into a binder.

[0023] Binder application: 1) Design 3D printing three-dimensional structure model according to needs; 2) Import the designed 3D printing three-dimensional structure model into the 3D printer; 3) Add the binder of the present invention and the stone powder for 3D printing to be used The materials are added to the trough of the 3D printer; 4) Start the 3D printer and print according to the designed digital model. The printing principle is to spray a layer of stone powder first, and then spray a layer of binder to form a layer of stone powder and a layer of The alternating structure of the binder is irradiated with ultraviolet light at the same time, and the binder is quickly cured un...

Embodiment 2

[0025] Binder preparation: add 15 parts by weight of aluminum silicate, 8 parts by weight of sodium persulfate, and 6 parts by weight of calcium hydroxide to 85 parts by weight of magnesium oxide sol, and use ultrasonic vibration to disperse and dissolve to prepare a viscous Binder.

[0026] Binder application: 1) Design 3D printing three-dimensional structure model according to needs; 2) Import the designed 3D printing three-dimensional structure model into the 3D printer; 3) Add the binder of the present invention and the stone powder for 3D printing to be used The materials are added to the trough of the 3D printer; 4) Start the 3D printer and print according to the designed digital model. The printing principle is to spray a layer of stone powder first, and then spray a layer of binder to form a layer of stone powder and a layer of The alternating structure of the binder is irradiated with ultraviolet light at the same time, and the binder is quickly cured under the irradi...

Embodiment 3

[0028] Binder preparation: Add 10 parts by weight of potassium silicate, 5 parts by weight of calcium persulfate, and 8 parts by weight of oxalic acid into 75 parts by weight of silica gel sol, and use ultrasonic vibration to disperse and dissolve to prepare a binder.

[0029] Binder application: 1) Design 3D printing three-dimensional structure model according to needs; 2) Import the designed 3D printing three-dimensional structure model into the 3D printer; 3) Add the binder of the present invention and the stone powder for 3D printing to be used The materials are added to the trough of the 3D printer; 4) Start the 3D printer and print according to the designed digital model. The printing principle is to spray a layer of stone powder first, and then spray a layer of binder to form a layer of stone powder and a layer of The alternating structure of the binder is irradiated with ultraviolet light at the same time, and the binder is quickly cured under the irradiation of ultravi...

Abstract

The invention relates to an adhesive for stone 3D printing and application thereof. When the adhesive is under the conditions of ultraviolet irradiation and normal temperature and pressure, a curing agent, sol ions and stone form stable chemical bonds, such as Si-O, Si-C, Al-O, Ca-O, Ca-Si and the like, so that the adhesive and the stone are connected into an integral body, thereby obtaining the stone product. The adhesive greatly accelerates popularization and application of stone 3D printing formation in living, and has broad market prospects.

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 stone 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 development a...
