Abstract

The invention discloses a 3D-printing composite material with fragrance and antibacterial property, a preparation method and an application thereof. The 3D-printing composite material is prepared fromthe following components in parts by weight: 40-97 parts of high-molecular polymer, 0.2-55 parts of spice agent, 0.1-5 parts of antibacterial agent, 0.2-5 parts of plasticizing additive, 0.5-10 partsof organic additive, 0.5-5 parts of dispersing agent, 0.05-1 part of antioxidant and 0-1 part of pigment powder. The 3D-printing composite material disclosed by the invention has the beneficial effects that the fragrance with multiple types of fragrances is achieved, the original odor of plastics can be effectively covered or reduced, the antibacterial property and the mechanical property are good, and the types and manufacturing processes of materials in the technical field of 3D printing are enriched; in addition, the 3D-printing composite material is non-toxic and harmless, waste materialscan be naturally biodegraded and also can be recycled, so that the economic cost is lower relatively.

Description

technical field [0001] The invention belongs to the technical field of new materials and new processing of polymer materials, and specifically relates to a 3D printing composite material with fragrance and antibacterial properties, a preparation method and an application thereof. Background technique [0002] 3D printing technology is a rapid prototyping manufacturing technology that is gradually developing. It is a precise and personalized rapid prototyping technology. advantage. Its basic principle is mainly based on polymer materials, using fused deposition modeling technology, and completing the construction and formation of object models by layer-by-layer printing and accumulation. [0003] At present, polylactic acid (PLA), polyacrylonitrile-polybutadiene-polystyrene terpolymer (ABS), polyurethane (TPU), and wood fiber wire (WOOD) are widely used in the market. Ordinary plastics, there are also some engineering plastics such as polycarbonate (PC), nylon (PA) and so o...
