Abstract

The invention discloses a 3D printing ABS composite material capable of continuously emitting light and a preparation method thereof. The preparation method comprises the following steps: respectively weighing long afterglow fluorescent powder, KH550, ABS particles and ABS powder; adding the KH550 into deionized water, carrying out hydrolyzing and stirring, adding fluorescent powder, performing refluxing, cooling and washing, carrying out vacuum drying to constant weight, and conducting grinding to obtain KH550 modified fluorescent powder; after the ABS powder is acidified by hydrochloric acid, grafting the acidified ABS powder with the KH550 modified fluorescent powder through HATU to obtain a composite material; and subjecting the composite material to melting and manufacturing through a 3D printing extruder, and carrying out extrusion and drawing to obtain the 3D printing ABS composite material capable of continuously emitting light. According to the preparation method, the combination of a long-afterglow luminescent material and a 3D printing technology is realized, and the prepared 3D printing composite material not only can continuously emit light, but also has good mechanical properties, can be applied to the aspects of medicine, the manufacturing industry, the food industry, the industry, the jewelry industry and the like, and greatly expands the application field of 3D printing.

Description

technical field [0001] The invention belongs to the technical field of polymer materials and 3D printing materials, and relates to a sustainable luminescent 3D printing ABS composite material and a preparation method thereof. Background technique [0002] In recent years, additive manufacturing, also known as 3D printing, has developed rapidly and become an important processing technology. It can quickly print prototypes of complex geometries, and has the advantages of low cost, high adaptability and material saving. It is a processing technology that is completely opposite to the traditional material removal processing method: firstly, the three-dimensional model is simulated and sliced ​​in the computer, and the three-dimensional structure is decomposed into a multi-layer two-dimensional structure; Extrusion printing; finally form a three-dimensional structural device exactly the same as the design model. Compared with removal processing, 3D printing has less waste of ra...
