Embodiment 1

[0026] 30 g of polyethylene glycol dimethacrylate, 3 g of benzoin methyl ether, 12 g of isobutanol, 0.5 g of red pigment, and 54.5 g of deionized water. Before printing, mix the above raw materials evenly and place them in the printing nozzle, and print with 3dp technology. The curing light source is an ultraviolet light source. After printing, take out the product, put it in the above mixed solution for another 30 minutes, and then place it under the ultraviolet light source for irradiation. It can be cured for 8 hours. The formula has the advantages of fast binder penetration, short setting time, high product strength, environmental protection and no pollution. It is suitable for use as a binder for 3dp printing of plaster materials. figure 1 It is the infrared spectrogram of pure gypsum powder; figure 2 It is the infrared spectrogram of the binder solidified molded gypsum product obtained in Example 1. Compared figure 1 As can be seen, figure 2 Center at 2800cm -1 N...

Abstract

The invention discloses a polyol acrylate type photosensitive bonding agent for gypsous material 3DP (three-dimensional printing) process and a preparation method thereof. The polyol acrylate type photosensitive bonding agent is characterized in that polyol acrylate type compounds are used as monomers; benzoic acid and derivatives of the benzoic acid are used as photoinitiators; ethanol or isobutanol is used as a flowing seeping promoter; an ultraviolet light source is used as a triggering light source; the gypsous material 3DP efficient bonding agent is prepared. In the prior art, inorganic materials such as gypsum use an ordinary 3DP technology, and the defects of low product initial strength, low printing speed, high post treatment difficulty and the like exist. Through the application of the method, the printing speed of the 3D printing gypsum product can be effectively accelerated; the initial strength of the 3D printing gypsum product can be effectively improved; the complicated post treatment process of the printed product is avoided, so that the manufacturing efficiency and the finished product quality of 3D printing products are greatly improved; the process complexity degree is reduced.

Description

technical field [0001] The invention relates to a polyol acrylate photosensitive adhesive for 3D printing of gypsum materials and a preparation method thereof, belonging to the technical field of 3D printing. Background technique [0002] 3D printing technology is a rapid prototyping technology from computer three-dimensional design model to physical entity. It is based on software layered discrete and numerical control forming system. , fused deposition, laminated solids, 3D printing and other molding processes, metal powder, plastic, cell tissue and other special materials are accumulated and bonded layer by layer, and finally superimposed and formed to create an emerging technology for physical products. This digital manufacturing mode can generate parts of any shape directly from computer graphics data, enabling manufacturing to extend to a wider range of production groups. [0003] In recent years, 3D printing has been widely used in more and more fields because of its...
