3D printing material with bacteriostatic function and preparation method thereof

Abstract

The invention discloses a 3D printing material with the bacteriostatic function and a preparation method thereof. The 3D printing material is prepared from the following components in parts by weight: 120-140 parts of ABS (acrylonitrile butadiene styrene copolymers), 2-8 parts of light dispersing agent, 2-8 parts of initiator, 10-20 parts of cross-linking agent, 10-20 parts of coupling agent, 10-30 parts of clam shell powder, 2-8 parts of elemental sulfur, 1-4 parts of medical stone powder, 1-4 parts of walnut shell ultrafine powder, 1-6 parts of limonene, 4-20 parts of toosendainin, 2-8 parts of sweet stevia extract and 0.2-0.4 part of additive. The 3D printing material new variety is provided for users to selectively use as required and the application and development space of the 3D printing material with ABS as the main raw material is greatly expanded from the aspect of the 3D printing material, so the significance is outstanding.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a material for 3D printing and a preparation method thereof. Background technique [0002] With the rapid development of 3D printing technology, the concept of 3D printing is gradually known to the public. FDM technology is to use ABS, polycarbonate (PC), polyphenylsulfone (PPSF), PLA and other thermoplastic materials to be heated and extruded into semi-molten filaments, which are deposited on a layer-by-layer basis to directly construct prototypes from 3DCAD data . This technique is commonly used in prototyping, assembly, functional testing and conceptual design. In addition, FDM technology can be applied to proofing and rapid manufacturing. [0003] ABS material, ABS, formerly known as acrylonitrile-butadiene-styrene copolymer, is the main core of household fused deposition (FDM) type wire. In terms of the nature of the material, ABS plastic is fairly easy to print fr...

AI Technical Summary

Problems solved by technology

[0004] However, on the one hand, this material has the characteristic of shrinking when it is cold, and it will partially fall off from the heating plate and hang in the air, causing problems.

In addition, if the height of the printed object is very high, sometimes the whole layer will be peeled off

Therefore, ABS printing cannot be done without a heating plate

On the other hand the smell when printing is very unpleasant

[0005] With the development of science and technology and social progress, 3D printing products are not limited to industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, guns and other fields, but also It has begun to enter people's daily life to make some living utensils or decorations, but the current application in life is still reflected in the use of the shape of the printed product, as well as the artistic design formed by its color and shape, etc. , there is still a lot of room for the application and development of 3D printing, and at the same time, the degradability, toughness and strength need to be further improved
