Abstract

The invention discloses a 3D printing material having a self-cleaning antibacterial function as well as a preparation method and an application of the 3D printing material. The 3D printing material consists of the following components: 70-85 parts of a high-molecular polymer, 1-5 parts of pigment powder, 1-5 parts of inorganic filler, 0.5-1.5 parts of a nanometer antibacterial agent and 10-20 parts of a binding material. The 3D printing material having the self-cleaning antibacterial function is prepared by the following steps: uniformly mixing the components; adding the uniformly mixed materials to a single-screw plastic extruder, extruding, cooling and shaping, drying, drawing and winding. The 3D printing material disclosed by the invention is excellent in toughness and mechanical property, and furthermore the 3D printing material is good in self-cleaning and antifouling properties; and the 3D printing material has high application potential.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a 3D printing material with self-cleaning and antibacterial functions, a preparation method and an application. Background technique [0002] 3D printing technology is a rapid prototyping technology that is gradually becoming popular at present. This is a green desktop rapid prototyping technology, which has the advantages of small size, low cost, low pollution, and convenient use. The basic principle is to use polymer materials as the base material, and use fused deposition molding or fused deposition molding technology to complete the structure and formation of object pairs by layer-by-layer printing. Thermoplastic filamentary polymer materials are continuously extruded in a molten state, and then solidified to form contoured thin layers, which are stacked layer by layer to finally form products, which can be stacked layer by layer under precise positionin...
