A kind of environment-friendly antibacterial material and preparation method thereof for 3D printing

Abstract

The invention discloses an environment-friendly and antibacterial material for 3D printing. The environment-friendly and antibacterial material mainly comprises materials in parts by weight as follows: 80-85 parts of thermoplastic resin, 10-15 parts of porous calcium carbonate, 3.0-5.0 parts of graphite, 1.0-1.5 parts of chlorothalonil and 0.2-0.3 parts of a silane coupling agent. The prepared environment-friendly and antibacterial material for 3D printing has excellent environment protection and antibacterial performance, excellent flowability and excellent mechanical performance due to the flowability and high-efficient adsorption performance of porous calcium carbonate and excellent environment protection and antibacterial performance of chlorothalonil and is suitable for a 3D printing technique. The invention further discloses a preparation method of the environment-friendly and antibacterial material for 3D printing. The production process is simple, the cost is low, and the material is safe, environment-friendly and has market application prospect.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to an environment-friendly antibacterial material for 3D printing. Background technique [0002] 3D printing technology is a new type of printing technology. Strictly speaking, 3D printing technology is a kind of rapid prototyping technology. It originated from the patent on 3D printing declared by Scans E.M. and Cima M.J. of the Massachusetts Institute of Technology in 1991. The difference between this technology and two-dimensional printing is that two-dimensional printing prints a flat two-dimensional pattern such as a document or a photo, while three-dimensional printing prints a three-dimensional object. The two have similarities. For example, two-dimensional printing is to spray ink and other materials on the printing material. Generally, the thickness is not high, a few microns. And if the substrate is printed not only once, but many times, the thickness of the "ink...

Problems solved by technology

The invention utilizes composite oxide nano C u f e2 o 4 As a silver carrier to prepare an antibacterial agent, it can have strong antibacterial, antibacterial, and long-lasting effects. The antibacterial rate against Escherichia coli and Staphylococcus aureus can reach more than 90%, and the antibacterial time is long, but this invention is not applicable to 3D Print

[0006] With the rapid development of 3D printing technology, 3D printing materials, as an important part of 3D printing technology, have received more and more attention. However, there are very few 3D printing materials with environmental protection and antibacterial functions, which greatly limits the selection of 3D printing materials. Therefore, it is of great significance to develop a 3D printing material with environmental protection and antibacterial function suitable for 3D printing to promote the development of 3D printing and enrich 3D printing materials.
